It is important for you to read and consider all information contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus in making your investment decision. You should also read and consider the information contained in the documents to which we have referred you in “Where You Can Find More Information” in this prospectus supplement and the accompanying prospectus.
Unless we have indicated otherwise, or the context otherwise requires, references in this prospectus supplement and the accompanying prospectus to “Duke Energy Florida,” “the Company,” “we,” “us” and “our” or similar terms are to Duke Energy Florida, LLC. References in this prospectus supplement to “First Mortgage Bonds” are to all of our first mortgage bonds issued under the Mortgage (as defined under “Description of the Sustainability Bonds” below) and from time to time outstanding.
Notice to Prospective Investors in the European Economic Area
None of this prospectus supplement, the accompanying prospectus or any related free writing prospectus is a prospectus for the purposes of Regulation (EU) 2017/1129 (the “Prospectus Regulation”). This prospectus supplement, the accompanying prospectus and any related free writing prospectus have been prepared on the basis that any offer of the Sustainability Bonds in any Member State of the European Economic Area (the “EEA”) will only be made to a legal entity which is a qualified investor under the Prospectus Regulation (“EEA Qualified Investors”). Accordingly, any person making or intending to make an offer in that Member State of Sustainability Bonds which are the subject of one of the offerings contemplated in this prospectus supplement, the accompanying prospectus and any related free writing prospectus may only do so with respect to EEA Qualified Investors. Neither Duke Energy Florida nor the underwriters have authorized, nor do they authorize, the making of any offer of Sustainability Bonds other than to EEA Qualified Investors.
Prohibition of Sales to EEA Retail Investors—The Sustainability Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, as amended (the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”) for offering or selling the Sustainability Bonds or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Sustainability Bonds or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

None of this prospectus supplement, the accompanying prospectus or any related free writing prospectus is a prospectus for the purposes of Regulation (EU) 2017/1129 as it forms part of domestic law in the United Kingdom by virtue of the European Union (Withdrawal) Act 2018, as amended by the European Union (Withdrawal Agreement) Act 2020 (the “EUWA”) (the “UK Prospectus Regulation”). This prospectus supplement, the accompanying prospectus and any related free writing prospectus have been prepared on the basis that any offer of Sustainability Bonds in the United Kingdom will only be made to a legal entity which is a qualified investor under the UK Prospectus Regulation (“UK Qualified Investors”).

Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law in the United Kingdom by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Sustainability Bonds or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the Sustainability Bonds or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

Special Redemption
Upon the occurrence of certain specific events described under “Description of the Sustainability Bonds—Redemption—Special Redemption,” we may redeem, at our option, the Sustainability Bonds of either series, together with all other outstanding First Mortgage Bonds, in whole, but not in part, at the make-whole redemption price applicable to the optional redemption of the Sustainability Bonds of such series (with respect to the 2031 Sustainability Bonds, at the redemption price applicable to the optional redemption of the 2031 Sustainability Bonds at any time before the 2031 Par Call Date, and with respect to the 2051 Sustainability Bonds, at the redemption price applicable to the optional redemption of the 2051 Sustainability Bonds at any time before the 2051 Par Call Date) as described
 
S-3

 
above, plus accrued and unpaid interest to, but excluding, the redemption date. See “Description of the Sustainability Bonds—Redemption—Special Redemption.”
No Sinking Fund
The Sustainability Bonds will not be entitled to the benefit of any sinking fund or to a special redemption by operation of a sinking fund.
Basis for Issuance of Additional First Mortgage Bonds
We will issue the Sustainability Bonds based upon the bondable value of property additions. Under the terms of the Mortgage, (i) as of September 30, 2021, we could issue additional First Mortgage Bonds in amounts up to approximately $5.5 billion based upon the bondable value of property additions (approximately $       billion after giving effect to this offering) and (ii) as of September 30, 2021, we could issue additional First Mortgage Bonds in amounts equal to approximately $630 million based upon the amount of previously authenticated First Mortgage Bonds that have been cancelled or delivered for cancellation.
Use of Proceeds
The aggregate net proceeds from the sale of the Sustainability Bonds, after deducting the respective underwriting discounts and related offering expenses and giving effect to the underwriters’ payment to us, will be approximately $      . We intend to use an amount equal to such net proceeds from the sale of the Sustainability Bonds to finance or refinance, in whole or in part, existing or new Eligible Projects as described under “Use of Proceeds.” Pending the disbursement of the aggregate net proceeds from the sale of the Sustainability Bonds to finance or refinance Eligible Projects, such net proceeds are expected to be used to pay down a portion of our outstanding intercompany short-term debt under our money-pool borrowing arrangement with Duke Energy Corporation. At November 1, 2021, we had approximately $648 million of outstanding short-term money-pool borrowings at an annual interest rate of 0.13%. See “Use of Proceeds.”
We expect that the sales of the 2031 Sustainability Bonds and the 2051 Sustainability Bonds will take place concurrently. The sales of the 2031 Sustainability Bonds and the 2051 Sustainability Bonds are not conditioned upon each other, and we may consummate the sale of one series and not the other, or consummate the sales at different times.
Book-Entry
Each series of the Sustainability Bonds will be represented by one or more global securities registered in the name of and deposited with or on behalf of The Depository Trust Company (“DTC”) or its nominee. Beneficial interests in each series of the Sustainability Bonds will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the global securities through either DTC in the United States or Clearstream Banking, S.A. (“Clearstream”) or Euroclear Bank SA/NV, as operator of the Euroclear System (the “Euroclear System”) in Europe if they are participants in those systems, or indirectly through organizations which are participants in those systems. This means that you will not receive a certificate for your Sustainability Bonds and Sustainability Bonds will not be registered in your name,

Risk Factors
An investment in the Sustainability Bonds involves risks. You should carefully consider the discussion of risks in “Risk Factors” included or incorporated by reference in this prospectus supplement and the other information in this prospectus supplement and the accompanying prospectus, including “Cautionary Statement Regarding Forward-Looking Information” in this prospectus supplement, before making an investment decision.
 
S-5

 
RISK FACTORS
In addition to the risk factor described below, you should carefully consider the risk factors in our Annual Report on Form 10-K for the year ended December 31, 2020 and our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2021, June 30, 2021 and September 30, 2021, each of which has been filed with the Securities and Exchange Commission (the “SEC”) and is incorporated by reference in this prospectus supplement and the accompanying prospectus, as well as all of the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision.
Additional Risks Related to the Sustainability Bonds
The Sustainability Bonds may not be a suitable investment for all investors seeking exposure to green, social or sustainable assets.
There is currently no clearly defined definition (legal, regulatory or otherwise) of, nor market consensus as to what constitutes, a “green,” “social,” “sustainable” or equivalently labeled project, or as to what precise attributes are required for a particular project to be defined as “green,” “social,” “sustainable” or such other equivalent label, nor can any assurance be given that such a clear definition or consensus will develop over time. No assurance or representation is given as to the suitability or reliability for any purpose of any second party opinion that may be made available in connection with the issuance of the Sustainability Bonds and, in particular, with respect to whether any Eligible Projects fulfill any environmental, social, sustainability or other criteria. Furthermore, any second party opinion is not, and should not be deemed to be, a recommendation by Duke Energy Florida or any other person to buy, sell or hold the Sustainability Bonds. Any second party opinion is not, nor shall it be deemed to be, incorporated in or form a part of this prospectus supplement or the accompanying prospectus. Any withdrawal of any opinion or any additional opinion attesting that Duke Energy Florida or Duke Energy Corporation is not complying in whole or in part with any matters for which any opinion is opining may have a material adverse effect on the value of the Sustainability Bonds and/or result in adverse consequences for certain investors with mandates to invest in securities to be used for a particular purpose.
The examples of Eligible Projects in “Use of Proceeds” are for illustrative purposes only and no assurance can be provided that disbursements for Eligible Projects with these specific characteristics will be made by Duke Energy Florida with the proceeds from the Sustainability Bonds. Neither the terms of the Sustainability Bonds nor the Mortgage require Duke Energy Florida to use the proceeds as described under “Use of Proceeds” and any failure by Duke Energy Florida to comply with the anticipated use of proceeds will not constitute a breach of or an event of default under the Sustainability Bonds or the Mortgage. Additionally, any information that Duke Energy Florida provides concerning the environmental or social impacts of the Sustainability Bonds will be estimates determined by its management to the best of its ability based on the information available to its at such time. The determinations giving rise to such impact information are inherently imprecise and should not be taken as statements of fact. Furthermore, the underwriters are not responsible for assessing or verifying whether the Eligible Projects meet the prescribed eligibility criteria or for the monitoring of the use of proceeds. There can be no assurance that the Eligible Projects funded with the proceeds from the Sustainability Bonds will meet investor expectations regarding environmental or social performance. Adverse environmental or social impacts may occur during the implementation of the Eligible Projects or the Eligible Projects may become controversial or criticized by activist groups or other stakeholders which may have a material adverse effect on the value of the Sustainability Bonds and/or result in adverse consequences for certain investors with mandates to invest in securities to be used for a particular purpose.
While no assurance can be provided that any such listing will occur, in the event that the Sustainability Bonds are listed or admitted to trading on any dedicated “green,” “social,” “environmental,” “sustainable” or other equivalently-labeled segment of any stock exchange or securities market (whether or not regulated), no representation or assurance can be given that such listing or admission would satisfy, whether in whole or in part, any present or future investor expectations or requirements, or that any such listing or admission to trading will be maintained during the life of the Sustainability Bonds. In the event that the Sustainability Bonds are so listed, any change to the listing or admission status of the Sustainability Bonds may have a material adverse effect on the value of the Sustainability Bonds and/or result in adverse consequences for certain investors with portfolio mandates to invest in securities to be used for a particular purpose.

The ability to control operation and maintenance costs;

The level of creditworthiness of counterparties to transactions;

The ability to obtain adequate insurance at acceptable costs;

Employee workforce factors, including the potential inability to attract and retain key personnel;

In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements included or incorporated by reference in this prospectus supplement and the accompanying prospectus might not occur or might occur to a different extent or at a different time than described. Forward-looking statements speak only as of the date they are made and we expressly disclaim an obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

The aggregate net proceeds from the sale of the Sustainability Bonds, after deducting the respective underwriting discounts and related offering expenses and giving effect to the underwriters’ payment to us, will be approximately $      million. We intend to allocate an amount equal to such net proceeds to finance or refinance, in whole or in part, existing or new Eligible Projects in the United States. Eligible Projects include disbursements made in the two years prior to the issue date of the Sustainability Bonds, or any time following the issue date of the Sustainability Bonds until December 15, 2024.
“Eligible Projects” mean projects that meet Eligibility Criteria (as defined below).
“Eligibility Criteria” means projects within the following categories:
Renewable Energy
1.
expenditures and investments related to the construction, development, expansion, production, acquisition, maintenance, transmission, research and development, and operation of renewable energy generation and infrastructure including solar power;
2.
expenditures related to transmission and distribution networks projects that aim to connect renewable energy sources, support increased deployment of renewables on the grid, or reduce greenhouse gas emissions through installation of equipment that will improve system efficiency or energy use management (e.g., transmission built for the purpose of connecting renewable generation resources);
3.
expenditures on the development, construction, maintenance, research and development, and acquisition of new non-hydro energy storage capacity;
Energy Efficiency
4.
expenditures and programs related to construction, development, expansion, production, acquisition, research and development, and maintenance of energy technologies or assets, such as smart meters and related communications networks, programs to aid customers with energy efficiency including energy efficiency rebates (electric only) and costs to provide customer energy audits;
Clean Transportation
5.
expenditures related to the procurement, maintenance, and operation of electric vehicles (“EV”) and associated infrastructure, such as installation of EV charging stations and infrastructure and procurement of EVs for company fleet;
Climate Change Adaptation
6.
investments in transmission and distribution infrastructure designed to make the system more resilient and improve customer reliability when considering climate change related impacts, such as severe weather events, including more frequent and severe hurricanes, as well as other impacts and changing weather patterns; and
Socioeconomic Advancement and Empowerment
7.
expenditures and programs related to enabling opportunities for diverse and small businesses/suppliers, such as procurement of products and services from diverse suppliers, programs that empower small businesses through training, education on potential business opportunities and mentoring, education assistance related to technology, infrastructure and professional development for minority populations, and resources to identify and fund businesses with diverse founders such as mentoring programs, access to professional services and networking.
 
S-9

 

Target Population: Minority-owned, female-owned, veteran-owned, LGBTQ+-owned and small businesses as defined by the Small Business Administration (“SBA”)/ suppliers or businesses owned by other excluded, marginalized or underserved individuals.
Additional Criteria for Use of Proceeds
We will not intentionally allocate any of the net proceeds from the sale of the Sustainability Bonds to:

Investments that receive an allocation of proceeds under any other Green, Social, or Sustainable Financing;

Activities related to the exploration, production or transporting of fossil fuels (e.g., coal, oil and gas); or

Consumption of fossil fuels for the purposes of power generation.
Nuclear energy is a key part of Duke Energy Corporation’s transition to net-zero, and we continue to make investments in maintaining and operating our nuclear generation fleet. Nonetheless, we will not intentionally allocate proceeds from any Sustainability Bonds to Nuclear energy.
The “Green Bond Principles”, the “Social Bond Principles” and the “Sustainability Bond Guidelines” (collectively, the “Principles”) are a set of voluntary guidelines for the issuance of green bonds, social bonds and sustainability bonds developed by a committee made up of issuers, investors and intermediaries in the green, social and sustainability bond markets and are intended to promote integrity in these markets through guidelines that recommend transparency, disclosure and reporting. The Principles have four components:

use of proceeds;

process for project evaluation and selection;

management of proceeds; and

reporting.
We anticipate that the use of the aggregate net proceeds from the sale of the Sustainability Bonds will be in alignment with the Principles, and we expect to apply the relevant requirements in the management of our use of proceeds as appropriate. Duke Energy Corporation has published its Sustainable Financing Framework pursuant to which it and its subsidiaries (including Duke Energy Florida) propose to make bond offerings that align with the Principles. Duke Energy Corporation has commissioned an outside consultant to conduct an external review of Duke Energy Corporation’s Sustainable Financing Framework, and to issue a second party opinion on the Framework’s environmental credentials, and its alignment with the Principles, among other things. Neither the second party opinion nor the information contained on such outside consultant’s website is and should be deemed a part of this prospectus supplement and the accomanying prospectus.
Process for Expenditure Evaluation and Selection
Duke Energy Corporation’s Sustainability Financing committee, which is comprised of members of Duke Energy Corporation’s Sustainability department together with members of Duke Energy Corporation’s Treasury department, will select expenditures based on the Eligibility Criteria set forth above and that adhere to the requirements of Duke Energy Corporation’s Environmental/Social Impact Assessments. Additionally, the committee will oversee internal tracking systems to manage the allocation of an amount equal to the aggregate net proceeds from the sale of the Sustainability Bonds to Eligible Projects.
Management of Proceeds for the Sustainability Bonds
So long as a series of Sustainability Bonds remains outstanding, our internal records will show the amount of the net proceeds from the issuance of such series of Sustainability Bonds allocated to the Eligible Projects, as well as the amount of net proceeds pending allocation. Pending allocation, an amount equal to the net proceeds from the issuance of Sustainability Bonds of a series will be held in accordance with
 
S-10

 
Duke Energy Corporation’s internal liquidity policy. Pending the allocation of the aggregate net proceeds from the sale of the Sustainability Bonds to finance or refinance Eligible Projects, such net proceeds are expected to be used to pay down a portion of outstanding intercompany short-term debt under our money-pool borrowing arrangement with Duke Energy Corporation. At November 1, 2021, we had approximately $648 million of outstanding short-term money-pool borrowings at an annual interest rate of 0.13%. An amount equal to the net proceeds from the sale of the Sustainability Bonds of each series will be allocated and managed by Duke Energy Corporation’s Finance department.
Payment of principal and interest on the Sustainability Bonds will be made from our general funds and will not be directly linked to the performance of any Eligible Projects. We will use reasonable efforts to substitute any material Eligible Projects that are no longer eligible as soon as practical upon identifying an appropriate substitute Eligible Project.
Reporting
Allocation Reporting
During the term of the Sustainability Bonds, we will provide, and keep readily available, on Duke Energy Corporation’s website, information on the allocation of an amount equal to the aggregate net proceeds of the Sustainability Bonds, to be updated at least annually until full allocation of such net proceeds and as necessary thereafter in the event of material developments. This information will include (i) amounts allocated to Eligible Projects, by category, (ii) the amount pending allocation, and (iii) assertions by management with respect to (i) and (ii).
The final allocation report will be accompanied by a report from an independent registered public accounting firm in respect of its examination of management’s assertions conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants.
Impact Reporting
Where feasible and subject to any confidentiality considerations, Duke Energy Corporation will report estimated environmental impacts (on an annual basis until full allocation), the respective calculation methodology and key assumptions for each metric, and case studies of Eligible Projects to which a portion of the aggregate net proceeds of the Sustainability Bonds are allocated.
Information contained on Duke Energy Corporation’s website is not and should not be deemed a part of this prospectus supplement, the accompanying prospectus or any other report or filing filed with the SEC. Neither the Sustainability Bonds nor the Mortgage requires Duke Energy Florida to use the net proceeds from the sale of the Sustainability Bonds as described above, and any failure of Duke Energy Florida to comply with the foregoing will not constitute a breach of or default under the Sustainability Bonds or the Mortgage. The above description of the use of the proceeds from the sale of the Sustainability Bonds is not intended to modify or add any covenant or other contractual obligation undertaken by Duke Energy Florida under the Sustainability Bonds or the Mortgage.

DESCRIPTION OF THE SUSTAINABILITY BONDS
We will issue the Sustainability Bonds as two new series of First Mortgage Bonds under an Indenture, dated as of January 1, 1944 (the “Original Indenture”), with The Bank of New York Mellon, as successor trustee (the “Mortgage Trustee”). The Original Indenture is supplemented by supplemental indentures, including by the Fifty-Eighth Supplemental Indenture to be dated as of [November 1], 2021 (the “Supplemental Indenture”), which establishes the specific terms of the Sustainability Bonds. In the following discussion, we will refer to the Original Indenture and all indentures supplemental to the Indenture together as the “Mortgage.”
Please read the following information concerning the Sustainability Bonds in conjunction with the statements under “Description of First Mortgage Bonds” in the accompanying prospectus, which the following information supplements and, in the event of any inconsistencies, supersedes. Capitalized terms not defined in this prospectus supplement are used as defined in the Mortgage and the Supplemental Indenture governing the Sustainability Bonds or as otherwise provided in the accompanying prospectus.
General
We will initially offer $      aggregate principal amount of the Sustainability Bonds, consisting of $      aggregate principal amount of the 2031 Sustainability Bonds and $      aggregate principal amount of the 2051 Sustainability Bonds. Subject to the limits contained in the Mortgage that are described under “—Basis for Issuance of the Sustainability Bonds,” we may, at any time, without the consent of the holders of the Sustainability Bonds, issue additional First Mortgage Bonds having the same ranking, interest rate, maturity and other terms (except for the price to the public, the issue date and, if applicable, the initial interest accrual date and the first interest payment date) as the Sustainability Bonds of either series being offered hereby; provided, however, that such additional First Mortgage Bonds must be fungible with the applicable Sustainability Bonds offered hereby for U.S. federal income tax purposes, and any such additional First Mortgage Bonds, together with the Sustainability Bonds of such series, will be taken to constitute the same series of First Mortgage Bonds under the Mortgage.
The Sustainability Bonds will be issuable in denominations of $2,000 and integral multiples of $1,000 above that amount. For more information on DTC, see “Book-Entry System—The Depository Trust Company” below.
We expect that the sales of the 2031 Sustainability Bonds and the 2051 Sustainability Bonds will take place concurrently. The sales of the 2031 Sustainability Bonds and the 2051 Sustainability Bonds are not conditioned upon each other, and we may consummate the sale of one series and not the other, or consummate the sales at different times.
Basis for Issuance of the Sustainability Bonds
We will issue the Sustainability Bonds under the Mortgage based upon the bondable value of property additions.

As of September 30, 2021, we could issue under the Mortgage, based upon the bondable value of property additions, up to approximately $5.5 billion of additional First Mortgage Bonds (approximately $      billion after giving effect to the offerings); and

As of September 30, 2021, we could issue under the Mortgage, based upon the amount of previously authenticated First Mortgage Bonds that have been canceled or delivered for cancellation, approximately $630 million of additional First Mortgage Bonds.
Maturity, Interest and Payment
The 2031 Sustainability Bonds will mature on December 15, 2031, and the 2051 Sustainability Bonds will mature on December 15, 2051.
We will pay interest on the 2031 Sustainability Bonds at the rate of    % per annum and the 2051 Sustainability Bonds at the rate of    % per annum. Interest on the Sustainability Bonds of each series will accrue from and including December    , 2021 or from the most recent interest payment date to which
 
S-12

 
interest on the Sustainability Bonds of such series has been paid or provided for. We will pay interest on the Sustainability Bonds of each series on June 15 and December 15 of each year, beginning on June 15, 2022. We will pay interest on the Sustainability Bonds of each series to the person(s) in whose name(s) such Sustainability Bonds are registered at the close of business on the record date for the applicable interest payment date, which will be the close of business on (i) the business day immediately preceding such interest payment date so long as all of the Sustainability Bonds of such series remain in book-entry only form or (ii) the tenth calendar day immediately preceding such interest payment date if any of the Sustainability Bonds of such series do not remain in book-entry only form. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If a due date for the payment of interest or principal falls on a day that is not a business day, then the payment will be made on the next succeeding business day, and no interest will accrue on the amounts payable for the period from and after the original due date and until the next business day.
Pursuant to the Mortgage, we will pay interest, to the extent enforceable under law, on any overdue installment of interest on the Sustainability Bonds at the highest rate of interest payable on any of the First Mortgage Bonds outstanding under the Mortgage.
Ranking and Security
The Sustainability Bonds will be secured by the lien of the Mortgage and will rank equally with all our other First Mortgage Bonds from time to time outstanding. At September 30, 2021, we had approximately $5.9 billion in aggregate principal amount of First Mortgage Bonds outstanding, which will rank equally with the Sustainability Bonds. In the opinion of our counsel, the Mortgage constitutes a first mortgage lien, subject only to permitted encumbrances and liens, on substantially all of the fixed properties owned by us, except miscellaneous properties specifically excepted. After-acquired property is covered by the lien of the Mortgage, subject to existing liens at the time such property is acquired.
Dividend Restrictions
So long as any First Mortgage Bonds are outstanding, we may only pay cash dividends on our common stock, and make any other distribution to Progress Energy, Inc., our common stockholder, out of our net income subsequent to December 31, 1943. For purposes of the Mortgage, the terms (i) “dividend” shall be interpreted so as to include distributions and (ii) “common stock” shall be interpreted so as to include membership interests.
Redemption
In the case of any redemption as described under “—Optional Redemption” below, any notice of redemption may state that the redemption will be conditional upon the Mortgage Trustee receiving sufficient funds to pay the principal, premium, if any, and interest on the Sustainability Bonds of each series to be redeemed on the date fixed for redemption and that if the Mortgage Trustee does not receive those funds, the redemption notice will not apply, and we will not be required to redeem those Sustainability Bonds of such series. If we elect to redeem each series of the Sustainability Bonds as described under “—Optional Redemption,” we will notify the Mortgage Trustee of our election at least 15 days prior to the redemption date, including in the notice of redemption a reasonably detailed computation of the redemption price, or manner of calculation if not then known.
In the case of any redemption as described under “—Special Redemption” below, we have agreed that before any such redemption date for either series of the Sustainability Bonds, we will deposit with the Mortgage Trustee a sum of money equal to the redemption price. If we elect to redeem any Sustainability Bonds of either series as described under “—Special Redemption,” we will notify the Mortgage Trustee of our election at least 45 days prior to the redemption date, or a shorter period acceptable to the Mortgage Trustee, including in the notice of redemption a reasonably detailed computation of the redemption price, or manner of calculation if not then known. In the event we fail to make the required deposit, all outstanding First Mortgage Bonds, including the Sustainability Bonds, shall immediately become due and payable.
 
S-13

 
Optional Redemption
2031 Sustainability Bonds
At any time before September 15, 2031 (which is the date that is three months prior to the maturity date of the Sustainability Bonds (the “2031 Par Call Date”)), we will have the right to redeem the 2031 Sustainability Bonds, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the 2031 Sustainability Bonds being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2031 Sustainability Bonds being redeemed that would be due if the 2031 Sustainability Bonds matured on the 2031 Par Call Date (exclusive of interest accrued to the redemption date), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) applicable to the 2031 Sustainability Bonds plus           basis points, plus, in either case, accrued and unpaid interest on the principal amount of the 2031 Sustainability Bonds being redeemed to, but excluding, such redemption date.
At any time on or after the 2031 Par Call Date, we will have the right to redeem the 2031 Sustainability Bonds, in whole or in part and from time to time, at a redemption price equal to 100% of the principal amount of the 2031 Sustainability Bonds being redeemed plus accrued and unpaid interest on the principal amount of the 2031 Sustainability Bonds being redeemed to, but excluding, such redemption date.
2051 Sustainability Bonds
At any time before June 15, 2051 (which is the date that is six months prior to the maturity date of the Sustainability Bonds (the “2051 Par Call Date”)), we will have the right to redeem the 2051 Sustainability Bonds, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the 2051 Sustainability Bonds being redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2051 Sustainability Bonds being redeemed that would be due if the 2051 Sustainability Bonds matured on the 2051 Par Call Date (exclusive of interest accrued to the redemption date), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate applicable to the 2051 Sustainability Bonds plus           basis points, plus, in either case, accrued and unpaid interest on the principal amount of the 2051 Sustainability Bonds being redeemed to, but excluding, such redemption date.
At any time on or after the 2051 Par Call Date, we will have the right to redeem the 2051 Sustainability Bonds, in whole or in part and from time to time, at a redemption price equal to 100% of the principal amount of the 2051 Sustainability Bonds being redeemed plus accrued and unpaid interest on the principal amount of the 2051 Sustainability Bonds being redeemed to, but excluding, such redemption date.
For purposes of the optional redemption provisions, the following terms have the following meanings:
Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the applicable series of Sustainability Bonds to be redeemed (assuming, for this purpose, that the 2031 Sustainability Bonds matured on the 2031 Par Call Date and the 2051 Sustainability Bonds matured on the 2051 Par Call Date), that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Sustainability Bonds.
Comparable Treasury Price” means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Quotation Agent obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations as determined by us.
Quotation Agent” means one of the Reference Treasury Dealers appointed by us.
Reference Treasury Dealer” means each of (i) BofA Securities, Inc., Goldman Sachs & Co. LLC and Mizuho Securities USA LLC and (ii) a Primary Treasury Dealer (as defined below) selected by each of
 
S-14

 
SMBC Nikko Securities America, Inc. and Truist Securities, Inc., or their respective affiliates or successors, each of which is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”); provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer, we shall substitute therefor another Primary Treasury Dealer.
Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.
Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date.
Notice of redemption shall be given not less than 10 nor more than 90 days prior to the date fixed for redemption to the holders of Sustainability Bonds to be redeemed, which, as long as the Sustainability Bonds are held in the book-entry only system, will be DTC, its nominee or a successor depositary. If the redemption notice is given and funds deposited as required, then interest will cease to accrue from and after the redemption date on all or such portions of the Sustainability Bonds so called for redemption. So long as the Sustainability Bonds are registered in the name of DTC, its nominee or a successor depositary, if we elect to redeem less than all of the Sustainability Bonds, DTC’s practice is to determine by lot the amount of the interest of each direct participant in DTC in the Sustainability Bonds to be redeemed. At all other times, the Mortgage Trustee shall draw by lot the particular Sustainability Bonds, or portions of them, to be redeemed. For further information on DTC and its practices, see “Book-Entry System—The Depository Trust Company” below.
Special Redemption
The Sustainability Bonds of each series, together with all other outstanding First Mortgage Bonds, are redeemable as a whole, but not in part, at our option, at the prices set forth below, upon not less than 30 nor more than 90 days’ notice in the event that:

all of our outstanding common stock is acquired by some governmental body or instrumentality and we elect to redeem all outstanding First Mortgage Bonds, including the Sustainability Bonds; or

all, or substantially all, of the mortgaged and pledged property constituting “bondable property,” as defined in the Mortgage, that is then subject to the Mortgage as a first lien shall be released from the lien of the Mortgage pursuant to the provisions thereof, and available moneys held by the Mortgage Trustee, including any moneys deposited by us for the purpose, are sufficient to redeem all outstanding First Mortgage Bonds, including the Sustainability Bonds, at the applicable redemption prices (together with accrued interest to the date of redemption) upon the happening of such event.
In the event of a special redemption, the Sustainability Bonds of either series will be redeemable at the make-whole redemption price applicable to the optional redemption of the Sustainability Bonds of such series (with respect to the 2031 Sustainability Bonds, at the redemption price applicable to the optional redemption of the 2031 Sustainability Bonds at any time before the 2031 Par Call Date and with respect to the 2051 Sustainability Bonds, at the redemption price applicable to the optional redemption of the 2051 Sustainability Bonds at any time before the 2051 Par Call Date) as set forth above under “—Optional Redemption,” plus accrued and unpaid interest to, but excluding, the redemption date.
Sinking Fund
The Sustainability Bonds will not be entitled to the benefit of any sinking fund or to a special redemption by operation of a sinking fund.
Satisfaction and Discharge of the Mortgage
Upon our request, all mortgaged property shall be reconveyed to us, the Mortgage shall be satisfied and discharged, and the lien of the Mortgage released, when:
 
S-15

 

we deliver to the Mortgage Trustee for cancellation all First Mortgage Bonds and coupons previously authenticated and not previously cancelled; or

all First Mortgage Bonds not previously cancelled or delivered to the Mortgage Trustee for cancellation shall be due and payable within one year, or are to be called for redemption within one year under arrangements satisfactory to the Mortgage Trustee for the giving of notice of redemption, and we have deposited with the Mortgage Trustee cash sufficient to pay at maturity or upon redemption all of such bonds; and

we have paid or caused to be paid all other sums payable under the Mortgage.
Concerning the Mortgage Trustee
The Bank of New York Mellon is the Mortgage Trustee. Duke Energy Florida and some of its affiliates have banking relationships with The Bank of New York Mellon and its affiliates. The Bank of New York Mellon or its affiliate also serves as trustee or agent under other indentures and agreements pursuant to which securities of Duke Energy Florida and of some of its affiliates are outstanding.
The holders of not less than a majority in principal amount of the First Mortgage Bonds outstanding have the right to direct the time, method and place of conducting any proceedings for any remedy available to, or conferred by the Mortgage upon, the Mortgage Trustee; provided, however, that the Mortgage Trustee may, if it determines in good faith that such direction would involve the Mortgage Trustee in personal liability or be unjustly prejudicial to the rights of the non-assenting bondholders, decline to follow such direction. The Mortgage Trustee will not be liable for any action that it takes or omits to take in good faith in accordance with any such direction.
 
S-16

 
CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS
The following discussion summarizes certain U.S. federal income tax considerations relevant to the acquisition, ownership and disposition of the Sustainability Bonds, and does not purport to be a complete analysis of all potential U.S. federal income tax considerations. This discussion only applies to Sustainability Bonds that are held as capital assets, within the meaning of section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), and that are purchased in the initial offering at the initial offering price by Non-U.S. Holders (as defined below).
This summary is based on the Code, administrative pronouncements, judicial decisions and regulations of the Treasury Department, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. This discussion does not describe all of the U.S. federal income tax considerations that may be relevant to Non-U.S. Holders in light of their particular circumstances or to Non-U.S. Holders subject to special rules, such as certain financial institutions, tax-exempt organizations, insurance companies, traders or dealers in securities or commodities, persons holding Sustainability Bonds as part of a hedge or other integrated transaction, accrual method taxpayers subject to special tax accounting rules as a result of their use of certain financial statements under Section 451(b) of the Code, or certain former citizens or residents of the United States. This discussion does not address any U.S. federal income tax consequences for U.S. taxpayers who purchase Sustainability Bonds. Persons considering the purchase of Sustainability Bonds are urged to consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. Furthermore, this discussion does not describe the effect of U.S. federal estate and gift tax laws or the effect of any applicable foreign, state or local laws.
We have not and will not seek any rulings or opinions from the Internal Revenue Service (the “IRS”) with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the acquisition, ownership or disposition of the Sustainability Bonds or that any such position would not be sustained.
Prospective investors should consult their own tax advisors with regard to the application of the U.S. federal income tax considerations discussed below to their particular situations as well as the application of any state, local, foreign or other tax laws, including gift and estate tax laws.
For purposes of this summary, a “Non-U.S. Holder” means a beneficial owner of a Sustainability Bond that, for U.S. federal income tax purposes, is neither a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) nor (i) an individual that is a citizen or resident of the United States; (ii) a corporation or other entity treated as a corporation for U.S. federal income tax purposes that is created or organized under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (A) a court within the United States is able to exercise primary supervision over its administration and one or more United States persons (as defined in the Code) have the authority to control all substantial decisions of such trust, or (B) the trust has made an election under the applicable Treasury regulations to be treated as a United States person.
If a partnership, or other entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds Sustainability Bonds, the tax treatment of a partner in such a partnership will generally depend upon the status of the partner and the activities of the partnership. Partners in a partnership holding Sustainability Bonds should consult their tax advisor as to the particular U.S. federal income tax considerations relevant to the acquisition, ownership and disposition of the Sustainability Bonds applicable to them.
Interest
It is anticipated, and this discussion assumes, that the Sustainability Bonds will not be issued with more than a de minimis amount of original issue discount. Except if interest on the Sustainability Bonds is effectively connected with the conduct by a Non-U.S. Holder of a trade or business within the United States, and subject to the discussions below under “Foreign Account Tax Compliance Act” and “Information
 
S-17

 
Reporting and Backup Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on payments of interest on the Sustainability Bonds provided that such Non-U.S. Holder (A) does not directly or indirectly, actually or constructively, own 10% or more of the total combined voting power of all classes of our equity entitled to vote, (B) is not a controlled foreign corporation that is related to us directly or constructively through stock ownership, (C) is not a bank receiving such interest on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business, and (D) satisfies certain certification requirements. Such certification requirements will be met if (x) the Non-U.S. Holder provides its name and address, and certifies on an IRS Form W-8BEN or IRS Form W-8BEN-E (or a substantially similar form), under penalties of perjury, that it is not a United States person or (y) a securities clearing organization or certain other financial institutions holding the Sustainability Bonds on behalf of the Non-U.S. Holder certifies on IRS Form W-8IMY, under penalties of perjury, that such certification has been received by it and furnishes us or our paying agent with a copy thereof. In addition, we or our paying agent must not have actual knowledge or reason to know that the beneficial owner of the Sustainability Bonds is a United States person.
If interest on the Sustainability Bonds is not effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States, but such Non-U.S. Holder does not satisfy the other requirements outlined in the preceding paragraph, interest on the Sustainability Bonds generally will be subject to U.S. withholding tax at a 30% rate (or a lower applicable treaty rate).
If interest on the Sustainability Bonds is effectively connected with the conduct by a Non-U.S. Holder of a trade or business within the United States, and, if certain tax treaties apply, is attributable to a permanent establishment or fixed base within the United States, the Non-U.S. Holder generally will be subject to U.S. federal income tax on a net income basis at the rate applicable to United States persons generally (and, with respect to corporate holders, may also be subject to a 30% branch profits tax or a lower applicable treaty branch profits tax rate). If interest on the Sustainability Bonds is effectively connected with the conduct by a Non-U.S. Holder of a trade or business within the United States, such interest payments will not be subject to U.S. withholding tax so long as the Non-U.S. Holder provides us or our paying agent with the appropriate documentation (generally an IRS Form W-8ECI).
Sale, Redemption or Other Taxable Disposition of the Sustainability Bonds
Subject to the discussion below under “Information Reporting and Backup Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal withholding tax with respect to gain, if any, recognized on the sale, redemption or other taxable disposition of the Sustainability Bonds. A Non-U.S. Holder will also generally not be subject to U.S. federal income tax with respect to such gain, unless (i) the gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States, and, if certain tax treaties apply, is attributable to a permanent establishment or fixed base within the United States, or (ii) in the case of a Non-U.S. Holder that is a nonresident alien individual, such Non-U.S. Holder is present in the United States for 183 or more days in the taxable year of the disposition and certain other conditions are satisfied. In the case described in (i) above, gain or loss recognized on the disposition of such Sustainability Bonds generally will be subject to U.S. federal income taxation in the same manner as if such gain or loss were recognized by a United States person, and, in the case of a Non-U.S. Holder that is a foreign corporation, may also be subject to the branch profits tax at a rate of 30% (or a lower applicable treaty branch profits tax rate). In the case described in (ii) above, the Non-U.S. Holder will be subject to a 30% tax (or a lower applicable treaty rate) on any capital gain recognized on the disposition of the Sustainability Bonds (after being offset by certain U.S. source capital losses).
Information Reporting and Backup Withholding
Information returns will be filed annually with the IRS in connection with payments we make on the Sustainability Bonds. Copies of these information returns may also be made available under the provisions of a specific tax treaty or other agreement to the tax authorities of the country in which the Non-U.S. Holder resides. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a United States person, information returns may be filed with the IRS in connection with the proceeds from a sale, redemption or other disposition of the Sustainability Bonds, and the Non-U.S. Holder may be subject to backup withholding (currently at a rate of 24%) on payments on the Sustainability Bonds or on

the proceeds from a sale, redemption or other disposition of the Sustainability Bonds. The certification procedures required to claim the exemption from withholding on interest described above will satisfy the certification requirements necessary to avoid the backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder generally will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is furnished to the IRS in a timely manner.
Foreign Account Tax Compliance Act
Under the Foreign Account Tax Compliance Act and related IRS guidance concerning foreign account tax compliance rules (“FATCA”), a 30% U.S. withholding tax is imposed on certain payments (which includes interest payments on the Sustainability Bonds) made to a non-United States entity that fails to take required steps to provide information regarding its “United States accounts” or its direct or indirect “substantial United States owners,” as applicable, or to make a required certification that it has no such accounts or owners. We will not be obligated to make any “gross up” or additional payments in respect of amounts withheld on the Sustainability Bonds if we determine that we must so withhold in order to comply with FATCA in respect of the amounts described above. Prospective investors should consult their own tax advisors regarding FATCA and whether it may be relevant to the ownership and disposition of the Sustainability Bonds.

BOOK-ENTRY SYSTEM
We have obtained the information in this section concerning DTC and its book-entry system and procedures from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.
Each series of the Sustainability Bonds initially will be represented by one or more fully registered global securities. Each global security will be deposited with, or on behalf of, DTC or any successor thereto and registered in the name of Cede & Co., DTC’s nominee.
Investors may elect to hold interests in a global security through either DTC in the United States or Clearstream or the Euroclear System in Europe if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream and the Euroclear System will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and the Euroclear System’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Citibank, N.A. will act as depositary for Clearstream and JPMorgan Chase Bank, N.A. will act as depositary for the Euroclear System (in such capacities, the “U.S. Depositaries”).
You may hold your interests in a global security in the United States through DTC, either as a participant in such system or indirectly through organizations which are participants in such system. So long as DTC or its nominee is the registered owner of the global securities representing the Sustainability Bonds, DTC or such nominee will be considered the sole owner and holder of the Sustainability Bonds for all purposes of the Sustainability Bonds and the Mortgage. Except as provided below, owners of beneficial interests in the Sustainability Bonds will not be entitled to have the Sustainability Bonds registered in their names, will not receive or be entitled to receive physical delivery of the Sustainability Bonds in definitive form and will not be considered the owners or holders of the Sustainability Bonds under the Mortgage, including for purposes of receiving any reports that we or the Mortgage Trustee deliver pursuant to the Mortgage. Accordingly, each person owning a beneficial interest in a Sustainability Bond must rely on the procedures of DTC or its nominee and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of Sustainability Bonds.
Unless and until we issue the Sustainability Bonds in fully certificated form under the limited circumstances described below under the heading “—Certificated Sustainability Bonds”:

you will not be entitled to receive physical delivery of a certificate representing your interest in the Sustainability Bonds;

all references in this prospectus supplement or in the accompanying prospectus to actions by holders will refer to actions taken by DTC upon instructions from its direct participants; and

all references in this prospectus supplement or the accompanying prospectus to payments and notices to holders will refer to payments and notices to DTC or Cede & Co., as the registered holder of the Sustainability Bonds, for distribution to you in accordance with DTC procedures.
The Depository Trust Company
DTC will act as securities depositary for the Sustainability Bonds. The Sustainability Bonds will be issued as fully registered securities registered in the name of Cede & Co. DTC is:

a limited-purpose trust company organized under the New York Banking Law;

a “banking organization” within the meaning of the New York Banking Law;

a member of the Federal Reserve System;

a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended.
DTC holds securities that its direct participants deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions, in deposited securities through
 
S-20

 
electronic computerized book-entry transfers and pledges between direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.
Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to indirect participants such as securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com. The contents of such website do not constitute part of this prospectus supplement.
If you are not a direct participant or an indirect participant and you wish to purchase, sell or otherwise transfer ownership of, or other interests in the Sustainability Bonds, you must do so through a direct participant or an indirect participant. DTC agrees with and represents to DTC participants that it will administer its book-entry system in accordance with its rules and by-laws and requirements of law. The SEC has on file a set of the rules applicable to DTC and its direct participants.
Purchases of the Sustainability Bonds under DTC’s system must be made by or through direct participants, which will receive a credit for the Sustainability Bonds on DTC’s records. The ownership interest of each beneficial owner is in turn to be recorded on the records of direct participants and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through which such beneficial owners entered into the transaction. Transfers of ownership interests in the Sustainability Bonds are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive physical delivery of certificates representing their ownership interests in the Sustainability Bonds, except as provided below in “—Certificated Sustainability Bonds.”
To facilitate subsequent transfers, all Sustainability Bonds deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Sustainability Bonds with DTC and their registration in the name of Cede & Co. or such other DTC nominee has no effect on beneficial ownership. DTC has no knowledge of the actual beneficial owners of the Sustainability Bonds. DTC’s records reflect only the identity of the direct participants to whose accounts such Sustainability Bonds are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.
Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.
Book-Entry Format
Under the book-entry format, the Mortgage Trustee will pay interest and principal payments to Cede & Co., as nominee of DTC. DTC will forward the payment to the direct participants, who will then forward the payment to the indirect participants or to the beneficial owners. You may experience some delay in receiving your payments under this system.
DTC is required to make book-entry transfers on behalf of its direct participants and is required to receive and transmit payments of principal, premium, if any, and interest on the Sustainability Bonds. Any direct participant or indirect participant with which you have an account is similarly required to make book-entry transfers and to receive and transmit payments with respect to Sustainability Bonds on your behalf. We and the Mortgage Trustee have no responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Sustainability Bonds or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.
 
S-21

 
The Mortgage Trustee will not recognize you as a holder of any Sustainability Bonds under the Mortgage and you can only exercise the rights of a holder indirectly through DTC and its direct participants. DTC has advised us that it will only take action regarding a Sustainability Bond if one or more of the direct participants to whom the Sustainability Bond is credited direct DTC to take such action. DTC can only act on behalf of its direct participants. Your ability to pledge Sustainability Bonds to indirect participants, and to take other actions, may be limited because you will not possess a physical certificate that represents your Sustainability Bonds.
Certificated Sustainability Bonds
Unless and until they are exchanged, in whole or in part, for Sustainability Bonds in definitive form in accordance with the terms of the Sustainability Bonds, the Sustainability Bonds may not be transferred except as a whole by DTC to a nominee of DTC; as a whole by a nominee of DTC to DTC or another nominee of DTC; or as a whole by DTC or a nominee of DTC to a successor of DTC or a nominee of such successor.
We will issue Sustainability Bonds to you or your nominees, in fully certificated registered form, rather than to DTC or its nominees, only if:

DTC notifies us that it is unwilling or unable to continue as depositary or DTC is no longer a registered clearing agency under the Securities Exchange Act of 1934, as amended, and we are unable to appoint a qualified successor within 90 days;

an event of default has occurred and is continuing with respect to the Sustainability Bonds; or

we, at our option, and subject to DTC’s procedures, elect to effect an exchange of global securities for Sustainability Bonds issued to you or your nominees.
If any of the above events occurs, DTC is required to notify all direct participants that Sustainability Bonds in fully certificated registered form are available through DTC. DTC will then surrender each global security representing the Sustainability Bonds along with instructions for re-registration. The Mortgage Trustee will re-issue the Sustainability Bonds in fully certificated registered form and will recognize the registered holders of the certificated Sustainability Bonds as holders under the Mortgage.
Global Clearance and Settlement Procedures
Initial settlement for the Sustainability Bonds will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream participants and/or Euroclear System participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and the Euroclear System, as applicable.
Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream participants or Euroclear System participants on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. Depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream participants and Euroclear System participants may not deliver instructions directly to their respective U.S. Depositaries.
Because of time-zone differences, credits of Sustainability Bonds received in Clearstream or the Euroclear System as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such Sustainability Bonds settled during such processing will be reported to the
 
S-22

 
relevant Euroclear System Participant or Clearstream participant on such business day. Cash received in Clearstream or the Euroclear System as a result of sales of the Sustainability Bonds by or through a Clearstream participant or a Euroclear System participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or the Euroclear System cash account only as of the business day following settlement in DTC.
Although DTC, Clearstream and the Euroclear System have agreed to the foregoing procedures in order to facilitate transfers of Sustainability Bonds among participants of DTC, Clearstream and the Euroclear System, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued or changed at any time.

We have entered into an underwriting agreement with respect to the Sustainability Bonds with the underwriters listed below for whom BofA Securities, Inc., Goldman Sachs & Co. LLC, Mizuho Securities USA LLC, SMBC Nikko Securities America, Inc. and Truist Securities, Inc. are acting as representatives. Subject to certain conditions, each of the underwriters has severally agreed to purchase the principal amounts of Sustainability Bonds indicated in the following table:

Truist Securities, Inc.
MUFG Securities Americas Inc.
Scotia Capital (USA) Inc.
TD Securities (USA) LLC
Total$            $            
The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the Sustainability Bonds are subject to certain conditions, including the receipt of legal opinions relating to certain matters. The underwriters must purchase all of the 2031 Sustainability Bonds if they purchase any of the 2031 Sustainability Bonds and the underwriters must purchase all of the 2051 Sustainability Bonds if they purchase any of the 2051 Sustainability Bonds. The sales of the 2031 Sustainability Bonds and the 2051 Sustainability Bonds are not conditioned upon each other, and we may consummate the sale of one series and not the other, or consummate the sales at different times. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.
We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of any of these liabilities.
The underwriters are offering the Sustainability Bonds subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Sustainability Bonds, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
Commissions and Discounts
The Sustainability Bonds sold by the underwriters to the public will initially be offered at the prices to the public set forth on the cover of this prospectus supplement and may be offered to certain dealers at these prices less a concession not in excess of (i)    % of the principal amount of the 2031 Sustainability Bonds or (ii)    % of the principal amount of the 2051 Sustainability Bonds. The underwriters may allow, and those dealers may reallow, a discount not in excess of (i)    % of the principal amount of the 2031 Sustainability Bonds or (ii)    % of the principal amount of the 2051 Sustainability Bonds to certain other dealers. If all the Sustainability Bonds are not sold at the prices to the public, the underwriters may change the prices to the public and the other selling terms.
The expenses of these offerings, not including the respective underwriting discounts, are estimated to be approximately $980,000. The underwriters have agreed to make a payment to us in an amount equal to $      , including in respect of expenses incurred by us in connection with these offerings.
 
S-24

 
Settlement
It is expected that delivery of the Sustainability Bonds will be made against payment for the Sustainability Bonds on or about the date specified on the cover page of this prospectus supplement, which is the third business day following the date of this prospectus supplement (such settlement cycle being referred to as “T+3”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Sustainability Bonds on the date of this prospectus supplement will be required, by virtue of the fact that the Sustainability Bonds initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Sustainability Bonds who wish to trade the Sustainability Bonds on the date of this prospectus supplement should consult their own advisors.
New Issues of Sustainability Bonds
Each series of the Sustainability Bonds is a new issue of securities with no established trading market. The Sustainability Bonds will not be listed on any securities exchange or included in any automated quotation system. We have been advised by the underwriters that the underwriters intend to make a market in each series of the Sustainability Bonds, but they are not obligated to do so and may discontinue market-making at any time without notice. No assurance can be given as to the liquidity of any trading markets for the Sustainability Bonds.
Price Stabilization and Short Positions
In connection with these offerings, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the prices of the Sustainability Bonds. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater aggregate principal amount of each series of the Sustainability Bonds than they are required to purchase in the offerings. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of each series of the Sustainability Bonds while the offerings are in process.
These activities by the underwriters may stabilize, maintain or otherwise affect the market prices of the Sustainability Bonds. As a result, the price of each series of the Sustainability Bonds may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.
Other Relationships
The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include, among other activities, securities trading and underwriting, commercial and investment banking, financial advisory, corporate trust, investment management, investment research, principal investment, hedging, financing and brokerage activities. In the ordinary course of their respective businesses, some of the underwriters and/or their affiliates have in the past and may in the future provide us and our affiliates with commercial banking, investment banking, financial advisory and other services for which they have received and in the future will receive customary fees.
In addition, in the ordinary course of their business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates.
Certain of the underwriters or their affiliates have a lending relationship with us and our affiliates. Certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us and our affiliates consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by
 
S-25

 
entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Sustainability Bonds offered hereby. Any such credit default swaps or short positions could adversely affect future trading price of the Sustainability Bonds offered hereby. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

DESCRIPTION OF FIRST MORTGAGE BONDS
General
We will issue First Mortgage Bonds in one or more series under an Indenture, dated as of January 1, 1944, with The Bank of New York Mellon, as successor trustee (the “Mortgage Trustee”), as supplemented to date (the “Mortgage”) and as proposed to be supplemented by one or more supplemental indentures, including one or more supplemental indentures relating to the First Mortgage Bonds. When we offer to sell a particular series of First Mortgage Bonds, we will describe the specific terms of these First Mortgage Bonds in a prospectus supplement.
In the following discussion, we will refer to all of our First Mortgage Bonds, including those already issued and those to be issued in the future, as “First Mortgage Bonds.”
The information we are providing you in this prospectus concerning the First Mortgage Bonds and the Mortgage is only a summary of the information provided in those documents and the information is qualified in its entirety by reference to the provisions of the Mortgage. You should consult the First Mortgage Bonds themselves, the Mortgage and other documents for more complete information on the First Mortgage Bonds or any particular series thereof. These documents appear as exhibits to the registration statement of which this prospectus is a part, or are incorporated by reference as exhibits to such registration statement, or will appear as exhibits to other documents that we will file with the SEC, which will be incorporated by reference into this prospectus. The Mortgage has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”) and you should refer to the Trust Indenture Act for the provisions that apply to the First Mortgage Bonds. In the summary below, we have included references to applicable section numbers of the Mortgage so that you can more easily locate the relevant provisions.

Provisions of a Particular Series
The First Mortgage Bonds may from time to time, be issued in one or more series. You should consult the prospectus supplement or any free writing prospectus relating to any particular issue of the First Mortgage Bonds for the following information:

the designation, series and aggregate principal amount of the First Mortgage Bonds;

the percentage of the principal amount for which we will issue and sell the First Mortgage Bonds;

the date of maturity for the First Mortgage Bonds;

the rate at which the First Mortgage Bonds will bear interest or the method of determining that rate;

the dates on which interest is payable;

the denominations in which we will authorize the First Mortgage Bonds to be issued, if other than $1,000 or integral multiples of $1,000;

whether we will offer the First Mortgage Bonds in the form of global bonds and, if so, the name of the depositary for any global bonds;

the terms applicable to any rights to convert First Mortgage Bonds into or exchange them for other of our securities or those of any other entity;

redemption terms and sinking fund provisions, if any; and

any other specific terms that do not conflict with the Mortgage.
For more information, see Section 2.01 of the Mortgage.
No series of the First Mortgage Bonds will be limited in aggregate principal amount except as provided in the Mortgage. Unless the applicable prospectus supplement states otherwise, the covenants contained in the Mortgage will not afford holders of the First Mortgage Bonds protection in the event of a change of control or highly leveraged transaction.
Form and Exchanges
Unless otherwise specified in the applicable prospectus supplement, we expect to issue the First Mortgage Bonds as fully registered bonds without coupons in denominations of $1,000 or any integral multiple of $1,000. Holders may exchange them, free of charge, for a like aggregate principal amount of other First Mortgage Bonds of different authorized denominations of the same series. Holders may also transfer the First Mortgage Bonds free of charge except for any stamp taxes or other governmental charges that may apply. The First Mortgage Bonds may be presented for transfer or exchange at the corporate trust office of the Trustee in New York, New York. For more information, see Sections 2.01 and 2.03 of the Mortgage.
Interest and Payment
The prospectus supplement for any First Mortgage Bonds will state the interest rate, the method of determination of the interest rate, and the date on which interest is payable. Unless the prospectus supplement states otherwise, principal and interest on First Mortgage Bonds held in (i) definitive or certificated form will be paid at the corporate trust office of the Mortgage Trustee in New York, New York, and (ii) global form will be paid as set forth herein under “Global Securities.”
Pursuant to the Mortgage, we will pay interest, to the extent enforceable under law, on any overdue installment of interest on the First Mortgage Bonds at the highest rate of interest payable on any of the First Mortgage Bonds outstanding under the Mortgage. For more information, see Section 2.01 and Article X of the Mortgage.
Redemption and Purchase of First Mortgage Bonds
If the First Mortgage Bonds are redeemable, the redemption terms will appear in the prospectus supplement. We may declare redemptions on at least 30 days’ notice to the holders of First Mortgage Bonds
 
3

 
to be redeemed and to the Mortgage Trustee. We have agreed that before the redemption date we will deposit with the Mortgage Trustee a sum of money sufficient to redeem the subject First Mortgage Bonds. Our failure to make this required deposit will constitute a completed default under the Mortgage on the specified redemption date and the First Mortgage Bonds called for redemption shall immediately become due and payable. For more information, see Article VIII of the Mortgage.
First Mortgage Bonds are redeemable, in whole but not in part, on not more than 90 days’ notice to holders, at a redemption price of 100% of the principal amount thereof, together with accrued interest to the date of redemption, in the event that:

all of our outstanding common stock is acquired by some governmental body or instrumentality and we elect to redeem all First Mortgage Bonds; or

all or substantially all the mortgaged and pledged property, constituting bondable property as defined in the Mortgage, that is then subject to the Mortgage as a first lien shall be released from the lien of the Mortgage under the provisions thereof, and available moneys held by the Mortgage Trustee, including any moneys deposited by us for the purpose, are sufficient to redeem all the First Mortgage Bonds at the redemption prices (together with accrued interest to the date of redemption) specified therein applicable to the redemption thereof upon the happening of such event.
For more information, see Section 8.08 of the Mortgage.
Maintenance Fund
The Mortgage provides that the amount expended for property additions (excluding several stated exceptions) will, at the end of each year, equal the minimum provision for depreciation, for each calendar year subsequent to December 31, 1943, and if at the end of any such year we have not expended such required amount, we will, on or before the next succeeding March 31, deposit with the Mortgage Trustee the difference in cash. Certain credits are allowed against cash so required to be deposited. During the three years immediately following a cash deposit with the Mortgage Trustee, we may at any time or from time to time withdraw cash in an amount equal to any available maintenance credit. Cash not so withdrawn shall be applied towards the payment due upon maturity or for the redemption of outstanding First Mortgage Bonds as provided in the Mortgage. For more information, see Sections 5.08 and 1.05 of the Mortgage.
We must provide the Mortgage Trustee with an annual maintenance certificate with respect to the bondable value of property additions.
The minimum provision for depreciation means an amount equal to:

15% of our gross operating revenues, net of the cost of electric energy purchased for resale; less

an amount equal to the aggregate of the charges to operating expense for maintenance; provided, however,

that the minimum provision for depreciation for any period shall not exceed the maximum provision for depreciation, as defined, for the period.
The maximum provision for depreciation shall mean as to each full calendar year, an amount equal to:

$755,000, plus

2.25% of the sum of all property additions after January 1, 1944 up to the beginning of the subject calendar year, less

2.25% of the aggregate amount of all retirements of bondable property during the period after January 1, 1944 up to the beginning of the subject calendar year.
For periods other than a calendar year, the maximum provision for depreciation shall be based upon the maximum provision for depreciation for the calendar year ended during such period multiplied by the number of calendar months or fractions thereof included in such period and divided by 12.

Ranking and Security
The First Mortgage Bonds will be secured by the lien of the Mortgage and will rank equally with all bonds outstanding thereunder. In the opinion of our counsel, the Mortgage constitutes a first mortgage lien, subject only to permitted encumbrances and liens, on substantially all of the fixed properties owned by us except miscellaneous properties specifically excepted. In addition, after-acquired property is covered by the lien of the Mortgage, subject to existing liens at the time such property is acquired. For more information, see the Preambles and Section 2.01 of the Mortgage.
Issuance of Additional First Mortgage Bonds
First Mortgage Bonds may be issued under the Mortgage in a principal amount equal to:

an amount not exceeding 60% of the bondable value of property additions, which term generally includes all of our tangible property that we are authorized to acquire, own and operate, that has become subject to the Mortgage and which is used in connection with the generation, purchase, transmission, distribution or sale of electricity for light, heat, power or other purposes;

an additional aggregate principal amount not exceeding the aggregate principal amount of refundable prior lien bonds deposited with the Mortgage Trustee or judicially determined to be invalid;

an additional aggregate principal amount not exceeding the aggregate principal amount of any outstanding First Mortgage Bonds that have been canceled or delivered for cancellation; and

an additional aggregate principal amount equal to the amount of cash deposited with the Mortgage Trustee against the issuance of bonds.
For more information, see Sections 4.03 thorough 4.06 of the Mortgage.
First Mortgage Bonds may be authenticated pursuant to the first and fourth bullet points above (and in certain cases pursuant to the second and third bullet points above) only if net earnings for 12 successive months in the 15 months immediately preceding the first day of the month in which application for additional First Mortgage Bonds is made shall be at least two times the annual interest charges on the First Mortgage Bonds and prior lien bonds outstanding and to be outstanding. For more information, see Sections 4.08 and 1.06 of the Mortgage.
Restriction on Dividends
Unless otherwise stated in the prospectus supplement, in the case of First Mortgage Bonds issued under this prospectus and any accompanying prospectus supplement, and so long as any First Mortgage Bonds are outstanding, we may only pay cash dividends on our common stock, and make any other distribution to Florida Progress, our common stockholder, out of our net income subsequent to December 31, 1943. For more information, see Section 5.24 of the Mortgage. For purposes of the Mortgage, the terms (i) “dividend” shall be interpreted so as to include distributions and (ii) “common stock” shall be interpreted so as to include membership interests.
Release and Substitution of Property
Subject to various limitations, property may be released from the lien of the Mortgage when sold or exchanged, upon the basis of:

cash deposited with the Mortgage Trustee;

the principal amount of any purchase money obligations pledged with the Mortgage Trustee;

the fair value of any property additions certified to the Mortgage Trustee and acquired by us in exchange for the property to be released; or

if non-bondable property is to be released, the fair value of property and certain securities certified to the Mortgage Trustee and acquired by us in exchange for the property to be released, less the principal amount of certain outstanding prior lien bonds.

For more information, see Section 9.03 of the Mortgage.
If all or substantially all of the mortgaged and pledged property constituting bondable property which at the time shall be subject to the lien of the Mortgage as a first lien shall be released, whether pursuant to our request or by eminent domain, then we are required to redeem all the First Mortgage Bonds and have agreed to deposit with the Mortgage Trustee sufficient cash for that purpose. Any new property acquired to take the place of any property released shall be subjected to the lien of the Mortgage. For more information, see Sections 8.08(b), 9.03, 9.05 and 9.11 of the Mortgage.
Modification of Mortgage
The Mortgage may generally be modified with the consent of the holders of not less than 75% in aggregate principal amount of First Mortgage Bonds outstanding which would be affected by the action proposed to be taken, except no such modifications shall:

extend the maturity of any First Mortgage Bonds, or reduce the interest rate or extend the time of payment thereof, or reduce the principal amount thereof, without the express consent of the holder of each First Mortgage Bond affected;

reduce the percentage of holders who must consent to the modifications referred to in this section without the consent of the holders of all First Mortgage Bonds outstanding;

permit the creation of a prior or equal lien on the pledged property; or

deprive any First Mortgage Bond of the lien of the Mortgage.
For more information, see Section 17.02 of the Mortgage.
Default
In the event of a completed default, the Mortgage Trustee or the holders of at least 25% of the outstanding First Mortgage Bonds may declare the principal of all outstanding First Mortgage Bonds immediately due and payable. The following are defined as completed defaults in the Mortgage:

default in the payment of principal of, and premium, if any, on any of the First Mortgage Bonds when due and payable, whether at maturity or by declaration, or otherwise;

default continued for 60 days in the payment of any interest on any of the First Mortgage Bonds;

default in the payment of principal or interest upon any outstanding prior lien bonds continued beyond any applicable grace period;

certain acts of bankruptcy, insolvency or reorganization; and

default continued for 60 days after written notice to us by the Mortgage Trustee (or to us and the Mortgage Trustee by the holders of at least 25% in principal amount of the then outstanding First Mortgage Bonds) in the observance or performance of any other covenant, agreement or condition contained in the Mortgage or in any of the First Mortgage Bonds.
For more information, see Section 10.01 of the Mortgage.
If all defaults have been cured, however, the holders of not less than a majority in aggregate principal amount of the First Mortgage Bonds then outstanding may rescind and annul the declaration and its consequences. If the Mortgage Trustee in good faith determines it to be in the interest of the holders of the First Mortgage Bonds, it may withhold notice of default, except in payment of principal, premium, if any, interest or sinking fund payments, if any, for retirement of First Mortgage Bonds. We are required by the Mortgage to report annually to the Mortgage Trustee as to the absence of default and compliance with the provisions of the Mortgage. For more information, see Sections 10.01, 10.02 and 5.23 of the Mortgage.
The holders of not less than a majority in principal amount of the First Mortgage Bonds outstanding have the right to direct the time, method and place of conducting any proceedings for any remedy available to, or conferred by the Mortgage upon, the Mortgage Trustee; provided, however, that the Mortgage Trustee may, if it determines in good faith that such direction would involve the Mortgage Trustee in personal
 
6

 
liability or be unjustly prejudicial to the rights of the non-assenting bondholders, decline to follow such direction. For more information, see Section 10.06 of the Mortgage.
Satisfaction and Discharge of the Mortgage
Upon our request, all mortgaged property shall be reconveyed to us, the Mortgage shall be satisfied and discharged, and the lien of the Mortgage released, when:

we deliver to the Mortgage Trustee for cancellation all First Mortgage Bonds and coupons previously authenticated and not previously cancelled; or;

all First Mortgage Bonds not previously cancelled or delivered to the Mortgage Trustee for cancellation shall be due and payable within one year, or are to be called for redemption within one year under arrangements satisfactory to the Mortgage Trustee for the giving of notice of redemption, and we have deposited with the Mortgage Trustee cash sufficient to pay at maturity or upon redemption of all of such bonds; and

we have paid or caused to be paid all other sums payable under the Mortgage.
Evidence to Be Furnished to the Mortgage Trustee Under the Mortgage
Upon any request or application by us to the Mortgage Trustee to take action that is dependent upon our compliance with conditions precedent (including covenant compliance) under the Mortgage, we shall provide to the Mortgage Trustee certificates and opinions required under the Mortgage with respect to compliance with such conditions precedent.
We may demonstrate compliance with Mortgage provisions regarding certificates and opinions by providing written statements to the Mortgage Trustee from our officers or experts we select. For instance, we may select an engineer or appraiser to provide a written statement regarding the value of property being certified or released, or an accountant regarding net earnings, or counsel regarding property titles and compliance with the Mortgage generally. In certain significant matters, applicable law requires that an accountant or engineer must be independent. For more information, see Section 314(d) of the Trust Indenture Act. We must file certificates and other papers each year and whenever certain events occur. Additionally, we must provide evidence from time to time demonstrating our compliance with the conditions and covenants under the Mortgage.
Concerning the Mortgage Trustee
In the normal course of business, the Mortgage Trustee or its affiliates may, from time to time, provide certain commercial banking, investment banking, and securities underwriting services to us and our affiliates. The Mortgage Trustee’s affiliate currently serves as Debt Securities Trustee under our Debt Securities Indenture described below.

In the following discussion, we refer to any subordinated obligations as the “Subordinated Debt Securities.” Unless the applicable prospectus supplement provides otherwise, we will use a separate Debt Securities Indenture for any Subordinated Debt Securities that we may issue. The Indenture (For Debt Securities) dated as of December 7, 2005 has been, and any future Debt Securities Indenture will be, qualified under the Trust Indenture Act and you should refer to the Trust Indenture Act for the provisions that apply to the Debt Securities.

Unless the applicable prospectus supplement states otherwise, the covenants contained in the applicable indenture will not afford holders of Debt Securities protection in the event we have a change in control or are involved in a highly-leveraged transaction.
Subordination
The applicable prospectus supplement may provide that a series of Debt Securities will be Subordinated Debt Securities, subordinate and junior in right of payment to all of our Senior Indebtedness, as defined below. If so, we will issue these securities under a separate Debt Securities Indenture for Subordinated Debt Securities. For more information, see Article XV of the form of Debt Securities Indenture.
Unless the applicable prospectus supplement states otherwise, no payment of principal of, including redemption and sinking fund payments, or any premium or interest on, the Subordinated Debt Securities may be made if:

there occur certain acts of bankruptcy, insolvency, liquidation, dissolution or other winding up of our company;

any Senior Indebtedness is not paid when due;

any applicable grace period with respect to other defaults with respect to any Senior Indebtedness has ended, the default has not been cured or waived and the maturity of such Senior Indebtedness has been accelerated because of the default; or

the maturity of the Subordinated Debt Securities of any series has been accelerated because of a default and Senior Indebtedness is then outstanding.
Upon any distribution of our assets to creditors upon any dissolution, winding-up, liquidation or reorganization, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all principal of, and any premium and interest due or to become due on, all outstanding Senior Indebtedness must be paid in full before the holders of the Subordinated Debt Securities are entitled to payment. For more information, see Section 1502 of the applicable Debt Securities Indenture. The rights of the holders of the Subordinated Debt Securities will be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions applicable to Senior Indebtedness until all amounts owing on the Subordinated Debt Securities are paid in full. For more information, see Section 1504 of the applicable Debt Securities Indenture.
Unless the applicable prospectus supplement states otherwise, the term “Senior Indebtedness” means:

all obligations (other than non-recourse obligations and the indebtedness issued under the Subordinated Debt Securities Indenture) of, or guaranteed or assumed by, us:

for borrowed money (including both senior and subordinated indebtedness for borrowed money, but excluding the Subordinated Debt Securities);

for the payment of money relating to any lease that is capitalized on our consolidated balance sheet in accordance with generally accepted accounting principles; or

indebtedness evidenced by bonds, debentures, notes or other similar instruments.
In the case of any such indebtedness or obligations, Senior Indebtedness includes amendments, renewals, extensions, modifications and refundings, whether existing as of the date of the Subordinated Debt Securities Indenture or subsequently incurred by us.
The Subordinated Debt Securities Indenture does not limit the aggregate amount of Senior Indebtedness that we may issue.
Form, Exchange and Transfer
Unless the applicable prospectus supplement states otherwise, we will issue Debt Securities only in fully registered form without coupons and in denominations of $1,000 and integral multiples of that amount. For more information, see Sections 201 and 302 of the applicable Debt Securities Indenture.

Holders may present Debt Securities for exchange or for registration of transfer, duly endorsed or accompanied by a duly executed instrument of transfer, at the office of the security registrar or at the office of any transfer agent we may designate. Exchanges and transfers are subject to the terms of the applicable indenture and applicable limitations for global securities. We may designate ourselves the security registrar.
No charge will be made for any registration of transfer or exchange of Debt Securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge that the holder must pay in connection with the transaction. Any transfer or exchange will become effective upon the security registrar or transfer agent, as the case may be, being satisfied with the documents of title and identity of the person making the request. For more information, see Section 305 of the applicable Debt Securities Indenture.
The applicable prospectus supplement will state the name of any transfer agent, in addition to the security registrar initially designated by us, for any Debt Securities. We may at any time designate additional transfer agents or withdraw the designation of any transfer agent or make a change in the office through which any transfer agent acts. We must, however, maintain a transfer agent in each place of payment for the Debt Securities of each series. For more information, see Section 602 of the applicable Debt Securities Indenture.
We will not be required to:

issue, register the transfer of, or exchange any Debt Securities or any tranche of any Debt Securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any Debt Securities called for redemption and ending at the close of business on the day of mailing; or

register the transfer of, or exchange any Debt Securities selected for redemption except the unredeemed portion of any Debt Securities being partially redeemed.

Payment and Paying Agents

For more information, see Section 307 of the applicable Debt Securities Indenture.
Unless the applicable prospectus supplement provides otherwise, we will pay principal and any premium and interest on Debt Securities at the office of the paying agent whom we will designate for this purpose. Unless the applicable prospectus supplement states otherwise, the corporate trust office of the Debt Securities Trustee in New York City will be designated as our sole paying agent for payments with respect to Debt Securities of each series. Any other paying agents initially designated by us for the Debt Securities of a particular series will be named in the applicable prospectus supplement. We may at any time add or delete paying agents or change the office through which any paying agent acts. We must, however, maintain a paying agent in each place of payment for the Debt Securities of a particular series. For more information, see Section 602 of the applicable Debt Securities Indenture.
All money we pay to a paying agent for the payment of the principal and any premium or interest on any Debt Security that remains unclaimed at the end of two years after payment is due will be repaid to us. After that date, the holder of that Debt Security shall be deemed an unsecured general creditor and may look only to us for these payments. For more information, see Section 603 of the applicable Debt Securities Indenture.
Redemption
You should consult the applicable prospectus supplement for any terms regarding optional or mandatory redemption of Debt Securities. Except for any provisions in the applicable prospectus supplement regarding Debt Securities redeemable at the holder’s option, Debt Securities may be redeemed only upon notice by mail not less than 30 nor more than 60 days prior to the redemption date. Further, if less than all of the Debt
 
11

 
Securities of a series, or any tranche of a series, are to be redeemed, the Debt Securities to be redeemed will be selected by the method provided for the particular series. In the absence of a selection provision, the Debt Securities Trustee will select a fair and appropriate method of selection. For more information, see Sections 403 and 404 of the applicable Debt Securities Indenture.
A notice of redemption we provide may state:

that redemption is conditioned upon receipt by the paying agent on or before the redemption date of money sufficient to pay the principal of and any premium and interest on the Debt Securities; and

that if the money has not been received, the notice will be ineffective and we will not be required to redeem the Debt Securities.
For more information, see Section 404 of the applicable Debt Securities Indenture.
Consolidation, Merger and Sale of Assets
We may not consolidate with or merge into any other person, nor may we transfer or lease substantially all of our assets and property to any person, unless:

the corporation formed by the consolidation or into which we are merged, or the person that acquires by conveyance or transfer, or that leases, substantially all of our property and assets:

is organized and validly existing under the laws of any domestic jurisdiction; and

expressly assumes by supplemental indenture our obligations on the Debt Securities and under the applicable indentures;

immediately after giving effect to the transaction, no event of default, and no event that would become an event of default, has occurred and is continuing; and

we have delivered to the Debt Securities Trustee an officer’s certificate and opinion of counsel as provided in the applicable indentures.
For more information, see Section 1101 of the applicable Debt Securities Indenture.
Events of Default
Unless the applicable prospectus supplement states otherwise, “event of default” under the applicable indenture with respect to Debt Securities of any series means any of the following:

failure to pay any interest due on any Debt Security of that series within 30 days;

failure to pay principal or premium, if any, when due on any Debt Security of that series;

failure to make any required sinking fund payment on any Debt Securities of that series;

breach of or failure to perform any other covenant or warranty in the applicable indenture with respect to Debt Securities of that series for 60 days (subject to extension under certain circumstances for another 120 days) after we receive notice from the Debt Securities Trustee, or we and the Debt Securities Trustee receive notice from the holders of at least 33% in principal amount of the Debt Securities of that series outstanding under the applicable indenture according to the provisions of the applicable indenture;

certain events of bankruptcy, insolvency or reorganization; and

any other event of default set forth in the applicable prospectus supplement.
For more information, see Section 801 of the applicable Debt Securities Indenture.
An event of default with respect to a particular series of Debt Securities does not necessarily constitute an event of default with respect to the Debt Securities of any other series issued under the applicable indenture.
If an event of default with respect to a particular series of Debt Securities occurs and is continuing, either the Debt Securities Trustee or the holders of at least 33% in principal amount of the outstanding
 
12

 
Debt Securities of that series may declare the principal amount of all of the Debt Securities of that series to be due and payable immediately. If the Debt Securities of that series are discount securities or similar Debt Securities, only the portion of the principal amount as specified in the applicable prospectus supplement may be immediately due and payable. If an event of default occurs and is continuing with respect to all series of Debt Securities issued under a Debt Securities Indenture, including all events of default relating to bankruptcy, insolvency or reorganization, the Debt Securities Trustee or the holders of at least 33% in principal amount of the outstanding Debt Securities of all series issued under that Debt Securities Indenture, considered together, may declare an acceleration of the principal amount of all series of Debt Securities issued under that Debt Securities Indenture. There is no automatic acceleration, even in the event of our bankruptcy or insolvency.
The applicable prospectus supplement may provide, with respect to a series of Debt Securities to which a credit enhancement is applicable, that the provider of the credit enhancement may, if a default has occurred and is continuing with respect to the series, have all or any part of the rights with respect to remedies that would otherwise have been exercisable by the holder of that series.
At any time after a declaration of acceleration with respect to the Debt Securities of a particular series, and before a judgment or decree for payment of the money due has been obtained, the event of default giving rise to the declaration of acceleration will, without further action, be deemed to have been waived, and the declaration and its consequences will be deemed to have been rescinded and annulled, if:

we have paid or deposited with the Debt Securities Trustee a sum sufficient to pay:

all overdue interest on all Debt Securities of the particular series;

the principal of and any premium on any Debt Securities of that series that have become due otherwise than by the declaration of acceleration and any interest at the rate prescribed in the Debt Securities;

interest upon overdue interest at the rate prescribed in the Debt Securities, to the extent payment is lawful; and

all amounts due to the Debt Securities Trustee under the applicable indenture; and

any other event of default with respect to the Debt Securities of the particular series, other than the failure to pay the principal of the Debt Securities of that series that has become due solely by the declaration of acceleration, has been cured or waived as provided in the applicable indenture.
For more information, see Section 802 of the applicable Debt Securities Indenture.
The applicable Debt Securities Indenture includes provisions as to the duties of the Debt Securities Trustee in case an event of default occurs and is continuing. Consistent with these provisions, the Debt Securities Trustee will be under no obligation to exercise any of its rights or powers at the request or direction of any of the holders unless those holders have offered to the Debt Securities Trustee reasonable indemnity against the costs, expenses and liabilities that may be incurred by it in compliance with such request or direction. For more information, see Section 903 of the applicable Debt Securities Indenture. Subject to these provisions for indemnification, the holders of a majority in principal amount of the outstanding Debt Securities of any series may direct the time, method and place of conducting any proceeding for any remedy available to the Debt Securities Trustee, or exercising any trust or power conferred on the Debt Securities Trustee, with respect to the Debt Securities of that series. For more information, see Section 812 of the applicable Debt Securities Indenture.
No holder of Debt Securities may institute any proceeding regarding the applicable indenture, or for the appointment of a receiver or a trustee, or for any other remedy under the applicable indenture unless:

the holder has previously given to the Debt Securities Trustee written notice of a continuing event of default of that particular series;

the holders of a majority in principal amount of the outstanding Debt Securities of all series with respect to which an event of default is continuing have made a written request to the Debt Securities Trustee, and have offered reasonable indemnity to the Debt Securities Trustee, to institute the proceeding as trustee; and
 
13

 

the Debt Securities Trustee has failed to institute the proceeding, and has not received from the holders of a majority in principal amount of the outstanding Debt Securities of that series a direction inconsistent with the request, within 60 days after notice, request and offer of reasonable indemnity.
For more information, see Section 807 of the applicable Debt Securities Indenture.
The preceding limitations do not apply, however, to a suit instituted by a holder of a Debt Security for the enforcement of payment of the principal of or any premium or interest on the Debt Securities on or after the applicable due date stated in the Debt Securities. For more information, see Section 808 of the applicable Debt Securities Indenture.
We must furnish annually to the Debt Securities Trustee a statement by an appropriate officer as to that officer’s knowledge of our compliance with all conditions and covenants under each of the indentures for Debt Securities. Our compliance is to be determined without regard to any grace period or notice requirement under the respective indenture. For more information, see Section 606 of the applicable Debt Securities Indenture.
Modification and Waiver
We and the Debt Securities Trustee, without the consent of the holders of the Debt Securities, may enter into one or more supplemental indentures for any of the following purposes:

to evidence the assumption by any permitted successor of our covenants in the applicable indenture and the Debt Securities;

to add one or more covenants or other provisions for the benefit of the holders of outstanding Debt Securities or to surrender any right or power conferred upon us by the applicable indenture;

to add any additional events of default;

to change or eliminate any provision of the applicable indenture or add any new provision to it, but if this action would adversely affect the interests of the holders of any particular series of Debt Securities in any material respect, the action will not become effective with respect to that series while any Debt Securities of that series remain outstanding under the applicable indenture;

to provide collateral security for the Debt Securities;

to establish the form or terms of Debt Securities according to the provisions of the applicable indenture;

to evidence the acceptance of appointment of a successor Debt Securities Trustee under the applicable indenture with respect to one or more series of the Debt Securities and to add to or change any of the provisions of the applicable indenture as necessary to provide for trust administration under the applicable indenture by more than one trustee;

to provide for the procedures required to permit the use of a non-certificated system of registration for any series of Debt Securities;

to change any place where:

the principal of and any premium and interest on any Debt Securities are payable;

any Debt Securities may be surrendered for registration of transfer or exchange; or

notices and demands to or upon us regarding Debt Securities and the applicable indentures may be served; or

to cure any ambiguity or inconsistency, but only by means of changes or additions that will not adversely affect the interests of the holders of Debt Securities of any series in any material respect.
For more information, see Section 1201 of the applicable Debt Securities Indenture.
The holders of at least a majority in aggregate principal amount of the outstanding Debt Securities of any series may waive:
 
14

 

compliance by us with certain provisions of the applicable indenture (see Section 607 of the applicable Debt Securities Indenture); and

any past default under the applicable indenture, except a default in the payment of principal, premium, or interest and certain covenants and provisions of the applicable indenture that cannot be modified or amended without consent of the holder of each outstanding Debt Security of the series affected (see Section 813 of the applicable Debt Securities Indenture).
The Trust Indenture Act may be amended after the date of the applicable indenture to require changes to the indenture. In this event, the indenture will be deemed to have been amended so as to effect the changes, and we and the Debt Securities Trustee may, without the consent of any holders, enter into one or more supplemental indentures to evidence or effect the amendment. For more information, see Section 1201 of the applicable Debt Securities Indenture.
Except as provided in this section, the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities issued pursuant to a Debt Securities Indenture, considered as one class, is required to change in any manner the applicable indenture pursuant to one or more supplemental indentures. If less than all of the series of Debt Securities outstanding under a Debt Securities Indenture are directly affected by a proposed supplemental indenture, however, only the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities of all series directly affected, considered as one class, will be required. Furthermore, if the Debt Securities of any series have been issued in more than one tranche and if the proposed supplemental indenture directly affects the rights of the holders of one or more, but not all, tranches, only the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities of all tranches directly affected, considered as one class, will be required. In addition, an amendment or modification:

may not, without the consent of the holder of each outstanding Debt Security affected:

change the maturity of the principal of, or any installment of principal of or interest on, any Debt Securities;

reduce the principal amount or the rate of interest, or the amount of any installment of interest, or change the method of calculating the rate of interest;

reduce any premium payable upon the redemption of the Debt Securities;

reduce the amount of the principal of any Debt Security originally issued at a discount from the stated principal amount that would be due and payable upon a declaration of acceleration of maturity;

change the currency or other property in which a Debt Security or premium or interest on a Debt Security is payable; or

impair the right to institute suit for the enforcement of any payment on or after the stated maturity, or in the case of redemption, on or after the redemption date, of any Debt Securities;

may not reduce the percentage of principal amount requirement for consent of the holders for any supplemental indenture, or for any waiver of compliance with any provision of or any default under the applicable indenture, or reduce the requirements for quorum or voting, without the consent of the holder of each outstanding Debt Security of each series or tranche affected; and

may not modify provisions of the applicable indenture relating to supplemental indentures, waivers of certain covenants and waivers of past defaults with respect to the Debt Securities of any series, or any tranche of a series, without the consent of the holder of each outstanding Debt Security affected.
A supplemental indenture will be deemed not to affect the rights under the applicable indenture of the holders of any series or tranche of the Debt Securities if the supplemental indenture:

changes or eliminates any covenant or other provision of the applicable indenture expressly included solely for the benefit of one or more other particular series of Debt Securities or tranches thereof; or
 
15

 

modifies the rights of the holders of Debt Securities of any other series or tranches with respect to any covenant or other provision.
For more information, see Section 1202 of the applicable Debt Securities Indenture.
If we solicit from holders of the Debt Securities any type of action, we may at our option by board resolution fix in advance a record date for the determination of the holders entitled to vote on the action. We shall have no obligation, however, to do so. If we fix a record date, the action may be taken before or after the record date, but only the holders of record at the close of business on the record date shall be deemed to be holders for the purposes of determining whether holders of the requisite proportion of the outstanding Debt Securities have authorized the action. For that purpose, the outstanding Debt Securities shall be computed as of the record date. Any holder action shall bind every future holder of the same security and the holder of every security issued upon the registration of transfer of or in exchange for or in lieu of the security in respect of anything done or permitted by the Debt Securities Trustee or us in reliance on that action, whether or not notation of the action is made upon the security. For more information, see Section 104 of the applicable Debt Securities Indenture.
Defeasance
Unless the applicable prospectus supplement provides otherwise, any Debt Security, or portion of the principal amount of a Debt Security, will be deemed to have been paid for purposes of the applicable indenture, and, at our election, our entire indebtedness in respect of the Debt Security, or portion thereof, will be deemed to have been satisfied and discharged, if we have irrevocably deposited with the Debt Securities Trustee or any paying agent other than us, in trust money, certain eligible obligations, as defined in the applicable indenture, or a combination of the two, sufficient to pay principal of and any premium and interest due and to become due on the Debt Security or portion thereof. For more information, see Section 701 of the applicable Debt Securities Indenture. For this purpose, unless the applicable prospectus supplement provides otherwise, eligible obligations include direct obligations of, or obligations unconditionally guaranteed by, the United States, entitled to the benefit of full faith and credit of the United States, and certificates, depositary receipts or other instruments that evidence a direct ownership interest in those obligations or in any specific interest or principal payments due in respect of those obligations.
Resignation, Removal of Debt Securities Trustee; Appointment of Successor
The Debt Securities Trustee may resign at any time by giving written notice to us or may be removed at any time by an action of the holders of a majority in principal amount of outstanding Debt Securities delivered to the Debt Securities Trustee and us. No resignation or removal of the Debt Securities Trustee and no appointment of a successor trustee will become effective until a successor trustee accepts appointment in accordance with the requirements of the applicable indenture. So long as no event of default or event that would become an event of default has occurred and is continuing, and except with respect to a Debt Securities Trustee appointed by an action of the holders, if we have delivered to the Debt Securities Trustee a resolution of our board of directors appointing a successor trustee and the successor trustee has accepted the appointment in accordance with the terms of the applicable indenture, the Debt Securities Trustee will be deemed to have resigned and the successor trustee will be deemed to have been appointed as trustee in accordance with the applicable indenture. For more information, see Section 910 of the applicable Debt Securities Indenture.
Notices
We will give notices to holders of Debt Securities by mail to their addresses as they appear in the Debt Security Register. For more information, see Section 106 of the applicable Debt Securities Indenture.
Title
The Debt Securities Trustee and its agents, and we and our agents, may treat the person in whose name a Debt Security is registered as the absolute owner of that Debt Security, whether or not that Debt Security may be overdue, for the purpose of making payment and for all other purposes. For more information, see Section 308 of the applicable Debt Securities Indenture.

Governing Law
The Debt Securities Indentures and the Debt Securities, including any Subordinated Debt Securities Indentures and Subordinated Debt Securities, will be governed by, and construed in accordance with, the law of the State of New York. For more information, see Section 112 of the applicable Debt Securities Indenture.
Concerning the Current Trustee or Future Trustees
In the normal course of business, the Trustee under our Indenture (For Debt Securities), dated as of December 7, 2005, or its affiliates provides, and any future trustee or its affiliates may, from time to time, provide certain commercial banking, investment banking, and securities underwriting services to us and our affiliates. The Debt Securities Trustee’s affiliate currently serves as Mortgage Trustee under our Mortgage described above.
GLOBAL SECURITIES
We may issue some or all of the First Mortgage Bonds and Debt Securities as book-entry securities. Any such book-entry securities will be represented by one or more fully registered global certificates. We will register each global security with or on behalf of a securities depositary identified in the applicable prospectus supplement. Each global security will be deposited with the securities depositary or its nominee or a custodian for the securities depositary.
As long as the securities depositary or its nominee is the registered holder of a global security representing securities described in this prospectus, that person will be considered the sole owner and holder of the global security and the securities it represents for all purposes. Except in limited circumstances, owners of beneficial interests in a global security:

may not have the global security or any securities it represents registered in their names;

may not receive or be entitled to receive physical delivery of certificated securities in exchange for the global security; and

will not be considered the owners or holders of the global security or any securities it represents for any purposes under the applicable securities or the related mortgage or indenture.
We will make all payments of principal and any premium and interest on a global security to the securities depositary or its nominee as the holder of the global security. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.
Ownership of beneficial interests in a global security will be limited to institutions having accounts with the securities depositary or its nominee, which are called “participants” in this discussion, and to persons that hold beneficial interests through participants. When a global security representing securities described in this prospectus is issued, the securities depositary will credit on its book-entry, registration and transfer system the principal amounts of securities the global security represents to the accounts of its participants. Ownership of beneficial interests in a global security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by:

the securities depositary, with respect to participants’ interests; and

any participant, with respect to interests the participant holds on behalf of other persons.
Payments participants make to owners of beneficial interests held through those participants will be the responsibility of those participants. The securities depositary may from time to time adopt various policies and procedures governing payments, transfers, exchanges and other matters relating to beneficial interests in a global security. None of the following will have any responsibility or liability for any aspect of the securities depositary’s or any participant’s records relating to beneficial interests in a global security representing securities described in this prospectus, for payments made on account of those beneficial interests or for maintaining, supervising or reviewing any records relating to those beneficial interests:

any agent of either of them.
