Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business, Liquidity, Basis of PresentationNature of Business, Liquidity and Basis of Presentation Nature of Business We design, manufacture, sell and, in certain cases, install solid-oxide fuel cell systems ("Energy Servers") for on-site power generation. Our Energy Servers utilize an innovative fuel cell technology and provide efficient energy generation with reduced operating costs and lower greenhouse gas emissions as compared to conventional fossil fuel generation. By generating power where it is consumed, our energy producing systems offer increased electrical reliability and improved energy security while providing a path to energy independence. We continue to monitor and adjust as appropriate our operations in response to the COVID-19 pandemic. During the three months ended March 31, 2021, we continued to experience supply chain disruptions due to COVID-19 as well as the Suez Canal blockage that affected logistics and container shortages. We put actions in place to mitigate the disruptions by booking alternate sea routes, creating virtual hubs and consolidating shipments coming from the same region. These mitigation efforts have increased the costs of our parts and materials. Liquidity We have generally incurred operating losses and negative cash flows from operations since our inception. With the series of new debt offerings, debt extensions and conversions to equity that we completed during 2020, we had $290.1 million of total outstanding recourse debt as of March 31, 2021, all of which is classified as long-term debt. Our recourse debt scheduled repayments will commence in June 2022. Our future capital requirements will depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, the rate of growth in the volume of system builds and the need for additional manufacturing space, the expansion of sales and marketing activities both in domestic and international markets, market acceptance of our product, our ability to secure financing for customer use of our Energy Servers, the timing of installations, and overall economic conditions including the impact of COVID-19 on our ongoing and future operations. In the opinion of management, the combination of our existing cash and cash equivalents and operating cash flows is expected to be sufficient to meet our operational and capital cash flow requirements and other cash flow needs for the next 12 months from the date of issuance of this Quarterly Report on Form 10-Q. Basis of Presentation We have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"), and as permitted by those rules, including all disclosures required by generally accepted accounting principles as applied in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated upon consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. As disclosed in the 2020 Annual Report on Form 10-K, effective on December 31, 2020, we lost our emerging growth company ("EGC") status which accelerated the adoption of ASC 842 - Leases . As a result, we adjusted our previously reported consolidated financial statements effective January 1, 2020. Principles of Consolidation These condensed consolidated financial statements reflect our accounts and operations and those of our subsidiaries in which we have a controlling financial interest. We use a qualitative approach in assessing the consolidation requirement for each of our variable interest entities ("VIEs"), which we refer to as a tax equity partnership (each such VIE, also referred to as our power purchase agreement entities ("PPA Entities")). This approach focuses on determining whether we have the power to direct those activities of the PPA Entities that most significantly affect their economic performance and whether we have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the PPA Entities. For all periods presented, we have determined that we are the primary beneficiary in all of our operational PPA Entities, as discussed in Note 11 - Portfolio Financings . We evaluate our relationships with the PPA Entities on an ongoing basis to ensure that we continue to be the primary beneficiary. All intercompany transactions and balances have been eliminated upon consolidation. The sale of an operating company with a portfolio of PPAs in which we do not have an equity interest is called a “Third-Party PPA.” We have determined that, although these entities are VIEs, we do not have the power to direct those activities of the Third-Party PPAs that most significantly affect their economic performance. We also do not have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the Third-Party PPAs. Because we are not the primary beneficiary of these activities, we do not consolidate Third-Party PPAs. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. The most significant estimates include the determination of the stand-alone selling price, including material rights estimates, inventory valuation, specifically excess and obsolescence provisions for obsolete or unsellable inventory and, in relation to property, plant and equipment (specifically Energy Servers), assumptions relating to economic useful lives and impairment assessments. Other accounting estimates include variable consideration relating to product performance guaranties, lease and non-lease components and related financing obligations such as incremental borrowing rates, estimated output, efficiency and residual value of the Energy Servers, product performance warranties and guaranties and extended maintenance, derivative valuations, estimates for recapture of the U.S. investment tax credit ("ITC") and similar federal tax benefits, estimates relating to contractual indemnities provisions, estimates for income taxes and deferred tax asset valuation allowances, and stock-based compensation costs. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, our allowance for doubtful accounts, stock-based compensation, the carrying value of our long-lived assets, inventory, financial assets, and valuation allowances for tax assets, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning the COVID-19 pandemic and the actions taken to contain it or treat it, as well as the economic impact on local, regional, national and international customers, suppliers and markets. We have made estimates of the impact of COVID-19 within our condensed consolidated financial statements and there may be changes to those estimates in future periods as new information becomes available. Actual results could differ materially from these estimates under different assumptions and conditions. Concentration of Risk Geographic Risk - The majority of our revenue and long-lived assets are attributable to operations in the United States for all periods presented. Additionally, we sell our Energy Servers in Japan, India and the Republic of Korea (collectively, the "Asia Pacific region"). In the three months ended March 31, 2021 and 2020, total revenue in the Asia Pacific region was 43% and 37%, respectively, of our total revenue. Credit Risk - At March 31, 2021 and December 31, 2020, one customer, SK Engineering and Construction Co., Ltd. ("SK E&C"), accounted for approximately 76% and 56% of accounts receivable. To date, we have not experienced any credit losses. Customer Risk - During the three months ended March 31, 2021, revenue from two customers, SK E&C and EdgeWise Energy LLC, accounted for approximately 43% and 30%, respectively of our total revenue. During the three months ended March 31, 2020, revenue from two customers, SK E&C and Duke Energy, accounted for approximately 36% and 31%, respectively, of our total revenue.

Accounting Policies [Abstract]
Summary of Significant Accounting PoliciesSummary of Significant Accounting Policies There have been no changes in our accounting policies from those reported in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. We have expanded our accounting policy relating to foreign currency transactions as follows: Foreign Currency Transactions The functional currencies of most of our foreign subsidiaries are the U.S. dollar since the subsidiaries are considered financially and operationally integrated with their domestic parent. For these subsidiaries, the foreign currency monetary assets and liabilities are remeasured into U.S. dollars at end-of-period exchange rates. Any currency transaction gains and losses are included as a component of other expense in our condensed consolidated statements of operations. The functional currency of our joint venture in the Republic of Korea is the local currency, the South Korean won ("KRW"), since the joint venture is financially independent of its U.S. parent and the KRW is the currency in which the joint venture generates and expends cash. Assets and liabilities of this entity are translated at the rate of exchange at the balance sheet date. Revenues and expenses are translated at the weighted average rate of exchange during the period. For this entity, translation adjustments resulting from the process of translating the KRW financial statements into U.S dollars are included in other comprehensive loss. Translation adjustments attributable to noncontrolling interests are allocated to and reported as part of the noncontrolling interests in the condensed consolidated financial statements. Recent Accounting Pronouncements Other than the adoption of the accounting guidance mentioned below, there have been no other significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements. Accounting Guidance Implemented in 2021 In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06"). The new standard simplifies the accounting for convertible instruments by eliminating the conversion option separation model for convertible debt that can be settled in cash and by eliminating the measurement model for beneficial conversion features. The guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted as early as fiscal years (including interim periods) beginning after December 15, 2020. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. There will no longer be a debt discount representing the difference between the carrying value, excluding issuance costs, and the principal of the convertible debt instrument and, as a result, there will no longer be interest expense from the amortization of the debt discount over the term of the convertible debt instrument. The amendments in this update also require the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. We elected to early adopt ASU 2020-06 as of January 1, 2021 using the modified retrospective transition method, which resulted in a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. Prior period condensed consolidated financial statements were not restated upon adoption. Upon adoption of ASU 2020-06, the Company combined the previously separated equity component with the liability component of our 2.5% Green Convertible Senior Notes due August 2025. These components are now together classified as Recourse debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and will be amortized as interest expense. Accordingly, we recorded a decrease to Accumulated deficit of $5.3 million, a decrease to Additional paid-in capital of $126.8 million, and an increase to Recourse debt, non-current of approximately $121.5 million. There is no deferred tax impact related to the adoption of ASU 2020-06 due to our full valuation allowance. Accounting Guidance Not Yet Adopted Cessation of LIBOR - In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"), which provides optional expedients for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the London

Fair Value Disclosures [Abstract]
Fair ValueFair Value Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis The tables below set forth, by level, our financial assets that are accounted for at fair value for the respective periods. The table does not include assets and liabilities that are measured at historical cost or any basis other than fair value (in thousands): Fair Value Measured at Reporting Date Using March 31, 2021 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 150,367 $ — $ — $ 150,367 $ 150,367 $ — $ — $ 150,367 Liabilities Derivatives: Natural gas fixed price forward contracts $ — $ 1,650 $ — $ 1,650 Embedded EPP derivatives — — 6,060 6,060 Interest rate swap agreements — 11,301 — 11,301 $ — $ 12,951 $ 6,060 $ 19,011 Fair Value Measured at Reporting Date Using December 31, 2020 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 235,902 $ — $ — $ 235,902 $ 235,902 $ — $ — $ 235,902 Liabilities Derivatives: Natural gas fixed price forward contracts $ — $ — $ 2,574 $ 2,574 Embedded EPP derivatives — — 5,541 5,541 Interest rate swap agreements — 15,989 — 15,989 $ — $ 15,989 $ 8,115 $ 24,104 Money Market Funds - Money market funds are valued using quoted market prices for identical securities and are therefore classified as Level 1 financial assets. Interest Rate Swap Agreements - Interest rate swap agreements are valued using quoted prices for similar contracts and are therefore classified as Level 2 financial assets. Interest rate swaps are designed as hedging instruments and are recognized at fair value on our condensed consolidated balance sheets. As of March 31, 2021, we expect $2.2 million of the loss on the interest rate swaps accumulated in other comprehensive loss to be reclassified into earnings in the next 12 months. Natural Gas Fixed Price Forward Contracts - As of December 31, 2020, natural gas fixed price forward contracts were valued using a combination of factors including the counterparty's credit rating and estimates of future natural gas prices and therefore, as no observable inputs to support market activity were available, were classified as Level 3 liabilities. T he leveling of each financial instrument is reassessed at the end of each period, and is based on pricing information received from third-party pricing sources. At March 31, 2021, we transferred $1.7 million of natural gas forward contracts from Level 3 to Level 2. Transfers between these hierarchy levels were based on the availability of sufficient observable inputs to meet Level 2 versus Level 3 criteria. We recognized an unrealized gain of $0.2 million and an unrealized loss of $0.6 million, as a result of a change in the fair value of our natural gas fixed price forward contracts during the three months ended March 31, 2021 and 2020, respectively. We realized gains of $0.7 million and $1.0 million for the three months ended March 31, 2021 and 2020, respectively, on the settlement of these contracts in cost of revenue on our condensed consolidated statements of operations. Embedded Escalation Protection Plan Derivative Liability in Sales Contracts - We estimate the fair value of the embedded Escalation Protection Plan ("EPP") derivatives in certain sales contracts using a Monte Carlo simulation model, which considers various potential electricity price curves over the sales contracts' terms. We use historical grid prices and available forecasts of future electricity prices to estimate future electricity prices. We have classified these derivatives as a Level 3 financial liability. For the three months ended March 31, 2021 and 2020, we recorded the fair value of the embedded EPP derivatives and recognized an unrealized loss of $0.5 million and an unrealized gain of $0.3 million, respectively, in (loss) gain on revaluation of embedded derivatives on our condensed consolidated statements of operations. The changes in the Level 3 financial liabilities during the three months ended March 31, 2021 were as follows (in thousands): Natural Embedded EPP Derivative Liability Total Liabilities at December 31, 2019 $ 6,968 $ 6,176 $ 13,144 Settlement of natural gas fixed price forward contracts (4,503) — (4,503) Changes in fair value 109 (635) (526) Liabilities at December 31, 2020 2,574 5,541 8,115 Settlement of natural gas fixed price forward contracts (731) — (731) Changes in fair value (193) 519 326 Transfer from Level 3 to Level 2 in fair value hierarchy (1,650) — (1,650) Liabilities at March 31, 2021 $ — $ 6,060 $ 6,060 To estimate the liabilities related to the EPP contracts an option pricing method was implemented through a Monte Carlo simulation. The unobservable inputs were simulated based on the available values for avoided cost and cost of electricity as calculated for March 31, 2021, using an expected growth rate of 7% over the contracts' life and volatility of 20%. The estimated growth rate and volatility were estimated based on the historical tariff changes for the period 2008 to 2020. Avoided cost is the transmission and distribution cost expressed in dollars per kilowatt hours avoided in the given year of the contract, calculated using the billing rates of the effective utility tariff applied during the quarter to the host account for which usage is offset by the generator. If the billing rates within the utility tariff change during the measurement period, the average of the amount of charge for each rate is weighted by the number of effective months for each amount. The inputs listed above would have had a direct impact on the fair values of the above derivatives if they were adjusted. Generally, an increase in natural gas prices and a decrease in electric grid prices would each result in an increase in the estimated fair value of our derivative liabilities. Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis Customer Receivables and Debt Instruments - The fair value for customer financing receivables is based on a discounted cash flow model, whereby the fair value approximates the present value of the receivables (Level 3). The senior secured notes, term loans and convertible notes are based on rates currently offered for instruments with similar maturities and terms (Level 3). The following table presents the estimated fair values and carrying values of customer receivables and debt instruments (in thousands): March 31, 2021 December 31, 2020 Net Carrying Fair Value Net Carrying Fair Value Customer receivables Customer financing receivables $ 49,395 $ 41,039 $ 50,746 $ 42,679 Debt instruments Recourse: 10.25% Senior Secured Notes due March 2027 68,703 70,873 68,614 71,831 2.5% Green Convertible Senior Notes due August 2025 221,387 400,009 99,394 426,229 Non-recourse: 7.5% Term Loan due September 2028 30,869 37,044 31,746 37,658 6.07% Senior Secured Notes due March 2030 76,130 85,830 77,007 89,654 LIBOR + 2.5% Term Loan due December 2021 111,410 113,165 114,138 116,113

Non-recourse debt refers to debt that is recourse to only our subsidiaries. The differences between the unpaid principal balances and the net carrying values apply to deferred financing costs. We and all of our subsidiaries were in compliance with all financial covenants as of March 31, 2021 and December 31, 2020. Recourse Debt Facilities 10.25% Senior Secured Notes due March 2027 - On May 1, 2020, we issued $70.0 million of 10.25% Senior Secured Notes in a private placement ("10.25% Senior Secured Notes"). The 10.25% Senior Secured Notes are governed by an indenture (the “Senior Secured Notes Indenture”) entered into among us, the guarantor party thereto and U.S. Bank National Association, in its capacity as trustee and collateral agent. The 10.25% Senior Secured Notes are secured by certain of our operations and maintenance agreements that previously were part of the security for the 6% Convertible Notes. We used the proceeds of this issuance to repay $70.0 million of our 10% Convertible Notes. The 10.25% Senior Secured Notes are supported by a $150.0 million indenture between us and U.S. Bank National Association, which contains an accordion feature for an additional $80.0 million of notes that can be issued on or prior to September 27, 2021. Interest on the 10.25% Senior Secured Notes is payable quarterly, commencing June 30, 2020. The 10.25% Senior Secured Notes Indenture contains customary events of default and covenants relating to, among other things, the incurrence of new debt, affiliate transactions, liens and restricted payments. On or after March 27, 2022, we may redeem all of the 10.25% Senior Secured Notes at a price equal to 108% of the principal amount of the 10.25% Senior Secured Notes plus accrued and unpaid interest, with such optional redemption prices decreasing to 104% on and after March 27, 2023, 102% on and after March 27, 2024 and 100% on and after March 27, 2026. Before March 27, 2022, we may redeem the 10.25% Senior Secured Notes upon repayment of a make-whole premium. If we experience a change of control, we must offer to purchase for cash all or any part of each holder’s 10.25% Senior Secured Notes at a purchase price equal to 101% of the principal amount of the 10.25% Senior Secured Notes, plus accrued and unpaid interest. The outstanding unpaid principal of the 10.25% Senior Secured Notes of $70.0 million was classified as non-current as of March 31, 2021. 2.5% Green Convertible Senior Notes due August 2025 - In August 2020, we issued $230.0 million aggregate principal amount of our 2.5% Green Convertible Senior Notes due August 2025, unless earlier repurchased, redeemed or converted ("Green Notes"). The principal amount of the Green Notes are $230.0 million, less initial purchaser's discount of $6.9 million and other issuance costs of $3.0 million resulting in net proceeds of $220.1 million. The Green Notes are senior, unsecured obligations accruing interest at a rate of 2.5% per annum, payable semi-annually in arrears on February 15 and August 15 of each year, beginning on February 15, 2021. We may not redeem the Green Notes prior to August 21, 2023. We may elect to redeem, at face value, all or any portion of the Green Notes at any time on or after August 21, 2023 and on or before the twenty-sixth trading day immediately before the maturity date, provided certain conditions are met. Before May 15, 2025, the noteholders have the right to convert their Green Notes only upon the occurrence of certain events, including a conversion upon satisfaction of a condition relating to the closing price of our common stock ("the Closing Price Condition"). If the Closing Price Condition is met on at least 20 of the last 30 consecutive trading days in any quarter, the noteholders may convert their Green Notes at any time during the immediately following quarter. The Closing Price Condition was met during the three months ended March 31, 2021 and accordingly, the noteholders may convert their Green Notes at any time during the quarter ending June 30, 2021. From and after May 15, 2025, the noteholders may convert their Green Notes at any time at their election until the close of business on the second trading day immediately before the maturity date. Should the noteholders elect to convert their Green Notes, we may elect to settle the conversion by paying or delivering, as applicable, cash, shares of our Class A common stock or a combination thereof. The initial conversion rate is 61.6808 shares of Class A common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $16.21 per share of Class A common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” as defined occur, the conversion rate will, in certain circumstances, be increased for a specified period of time. We adopted ASU 2020-06 as of January 1, 2021 using the modified retrospective transition method. Upon adoption, we combined the previously separated equity component of the Green Notes with the liability component, which is now together classified as debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and amortized as interest expense. Accordingly, we recorded a net decrease to Accumulated deficit of $5.3 million, a decrease to Additional paid-in capital of $126.8 million, and an increase to Recourse debt, non-current, of approximately $121.5 million. As of March 31, 2021, the remaining lives of the Green Notes are approximately 4.4 years and accordingly, the Green Notes are classified as long-term debt. Interest expense for the three months ended March 31, 2021 was $1.2 million, including amortization of issuance costs of $0.5 million. Non-recourse Debt Facilities 7.5% Term Loan due September 2028 - In December 2012 and later amended in August 2013, PPA IIIa entered into a $46.8 million credit agreement to fund the purchase and installation of our Energy Servers. The loan bears a fixed interest rate of 7.5% payable quarterly. The loan requires quarterly principal payments which began in March 2014. The credit agreement requires us to maintain a debt service reserve for all funded systems, the balance of which was $3.8 million and $3.8 million as of March 31, 2021 and December 31, 2020, respectively, which was included as part of long-term restricted cash in the condensed consolidated balance sheets. The loan is secured by all assets of PPA IIIa. 6.07% Senior Secured Notes due March 2030 - The notes bear a fixed interest rate of 6.07% per annum payable quarterly, which began in December 2015 and ends in March 2030. The note purchase agreement requires us to maintain a debt service reserve, the balance of which was $8.7 million and $8.5 million as of March 31, 2021 and December 31, 2020, respectively, which was included as part of long-term restricted cash in the condensed consolidated balance sheets. The notes are secured by all the assets of the PPA IV. LIBOR + 2.5% Term Loan due December 2021 - In June 2015, PPA V entered into a $131.2 million term loan due December 2021. The current portion of the LIBOR + 2.5% Term Loan as of March 31, 2021 and December 31, 2020 was $111.4 million and $114.1 million, respectively. There was no non-current portion of this loan as of March 31, 2021 and December 2020. In accordance with the credit agreement, PPA V was issued floating rate debt based on LIBOR plus a margin, paid quarterly. The applicable margins used for calculating interest expense are 2.25% for years 1-3 following the Term Conversion Date and 2.5% thereafter. For the lenders’ commitments to the loan and the commitments to a letter of credit ("LC") facility, the PPA V also pays commitment fees at 0.50% per annum over the outstanding commitments, paid quarterly. The loan is secured by all the assets of the PPA V and requires quarterly principal payments which began in March 2017. In connection with the floating-rate credit agreement, in July 2015, PPA V entered into pay-fixed, receive-float interest rate swap agreements to convert its floating-rate loan into a fixed-rate loan. The agreement also included commitments to a Letter of Credit facility with the aggregate principal amount of $6.4 million, later adjusted down to $6.2 million. The amount reserved under the letter of credit as of March 31, 2021 and December 31, 2020 was $5.4 million and $5.2 million, respectively, and the unused capacity was $0.8 million and $1.0 million, respectively. Related Party Debt Portions of the above described recourse and non-recourse debt were held by various related parties. See Note 12 - Related Party Transactions for a full description.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial InstrumentsDerivative Financial Instruments Interest Rate Swaps We use various financial instruments to minimize the impact of variable market conditions on our results of operations. We use interest rate swaps to minimize the impact of fluctuations of interest rate changes on our outstanding debt where LIBOR is applied. We do not enter into derivative contracts for trading or speculative purposes. The fair values of the derivatives designated as cash flow hedges as of March 31, 2021 and December 31, 2020 on our condensed consolidated balance sheets are as follows (in thousands): March 31, December 31, 2021 2020 Liabilities Accrued expenses and other current liabilities $ 11,301 $ 15,989 PPA V - In July 2015, PPA V entered into nine interest rate swap agreements to convert a variable interest rate debt to a fixed rate and we designated and documented the interest rate swap arrangements as cash flow hedges. Three of these swaps matured in 2016, three will mature on December 31, 2021 and the remaining three will mature on June 30, 2031. The effective change is recorded in accumulated other comprehensive loss and is recognized as interest expense on settlement. The notional amounts of the swaps are $180.7 million and $181.4 million as of March 31, 2021 and December 31, 2020, respectively. We measure the swaps at fair value on a recurring basis. Fair value is determined by discounting future cash flows using LIBOR rates with appropriate adjustment for credit risk. We realized immaterial gains attributable to the change in valuation during the three months ended March 31, 2021 and 2020, and these gains are included in other expense, net, in the condensed consolidated statements of operations. The changes in fair value of the derivative contracts designated as cash flow hedges and the amounts recognized in accumulated other comprehensive loss and in earnings are as follows (in thousands): Three months ended March 31, 2021 2020 Beginning balance $ 15,989 $ 9,238 (Gain) loss recognized in other comprehensive loss (4,164) 8,356 Amounts reclassified from other comprehensive loss to earnings (489) (142) Net (gain) loss recognized in other comprehensive loss (4,653) 8,214 Gain recognized in earnings (35) (37) Ending balance $ 11,301 $ 17,415 Embedded EPP Derivatives in Sales Contracts

Our lease for our Sunnyvale manufacturing facilities was entered into in April 2005 and expired in December 2020. In January 2021, we extended this lease to December 2023. In June 2020 and in March 2021, we signed leases in Fremont that will expire in 2027 and 2036, respectively, to replace our manufacturing facilities in Sunnyvale and Mountain View. The existing plants together comprise approximately 534,894 square feet of space. We lease additional office space as field offices in the United States and around the world including in Dubai, India, the Republic of Korea, China and Taiwan. Certain of these arrangements have free rent periods or escalating rent payment provisions. We recognize lease cost under such arrangements on a straight-line basis over the life of the leases. During the quarters ended March 31, 2021 and 2020, rent expense for all occupied facilities was $3.1 million and $2.1 million, respectively. Our leases have remaining lease terms ranging from less than 1 year to 15 years, some of which include options to extend the leases. The lease term is the non-cancelable period of the lease and includes options to extend or terminate the lease when it is reasonably certain that an option will be exercised.

Prior to our adoption of ASC 842 as of January 1, 2020, such arrangements with customers that qualified as leases were classified as either sales-type leases or operating leases. For all pre-existing Managed Services arrangements or Portfolio Financings through PPA Entities, we have carried over the accounting classifications for those transactions and continue to account for such transactions as either sales-type leases or operating leases under ASC 842. Customer arrangements under Managed Services and Portfolio Financings through PPA Entities entered into after January 1, 2021 do not contain a lease under ASC 842 and are accounted for under ASC 606 as revenue arrangements. Lease agreements under our Managed Services arrangements and Portfolio Financings through PPA Entities include non-cancellable lease terms, during which terms the majority of our investment in Energy Servers under lease are typically recovered. We mitigate remaining residual value risk of its Energy Servers through its provision of maintenance on the Energy Servers during the lease term and through insurance whose proceeds are payable in the event of theft, loss, damage, or destruction. Managed Services Financings - Our Managed Services arrangements with financiers are accounted for as financing transactions. Payments received from the financier are recognized as financing obligations in our condensed consolidated balance sheets. These financing obligations are included in each agreements' contract value and are recognized as short-term or long-term liabilities based on the estimated payment dates. The lease agreements expire on various dates through 2034 and there was no recorded rent expense for the three months ended March 31, 2021 and 2020.

The following are the aggregate carrying values of our VIEs' assets and liabilities in our condensed consolidated balance sheets, after eliminations of intercompany transactions and balances, including each of the PPA Entities in the PPA IIIa transaction, the PPA IV transaction, and the PPA V transaction (in thousands): March 31, December 31, 2020 Assets Current assets: Cash and cash equivalents $ 856 $ 1,421 Restricted cash 1,686 4,698 Accounts receivable 4,359 4,420 Customer financing receivable 5,515 5,428 Prepaid expenses and other current assets 1,822 3,048 Total current assets 14,238 19,015 Property and equipment, net 246,216 252,020 Customer financing receivable, non-current 43,880 45,268 Restricted cash, non-current 15,367 15,320 Other long-term assets 38 37 Total assets $ 319,739 $ 331,660 Liabilities Current liabilities: Accrued expenses and other current liabilities $ 14,587 $ 19,510 Deferred revenue and customer deposits 662 662 Non-recourse debt 118,468 120,846 Total current liabilities 133,717 141,018 Deferred revenue and customer deposits, non-current 5,909 6,072 Non-recourse debt, non-current 99,942 102,045 Total liabilities $ 239,568 $ 249,135 As of January 1, 2020, the flip date, we are the majority owner shareholder in PPA IIIa receiving 95% of all cash distributions and profits and losses. In addition, we consolidated each PPA Entity as VIEs in the PPA IV transaction and PPA V transaction, as we remain the minority shareholder in each of these transactions but have determined that we are the primary beneficiary of these VIEs. These PPA Entities contain debt that is non-recourse to us and own Energy Server assets for which we do not have title. We believe that by presenting assets and liabilities separate from the PPA Entities, we provide a better view of the true operations of our core business. The table below provides detail into the assets and liabilities of Bloom Energy separate from the PPA Entities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and ContingenciesCommitments and Contingencies Commitments Purchase Commitments with Suppliers and Contract Manufacturers - In order to reduce manufacturing lead-times and to ensure an adequate supply of inventories, we have agreements with our component suppliers and contract manufacturers to allow long lead-time component inventory procurement based on a rolling production forecast. We are contractually obligated to purchase long lead-time component inventory procured by certain manufacturers in accordance with our forecasts. We can generally give notice of order cancellation at least 90 days prior to the delivery date. However, we issue purchase orders to our component suppliers and third-party manufacturers that may not be cancellable. As of March 31, 2021 and December 31, 2020, we had no material open purchase orders with our component suppliers and third-party manufacturers that are not cancellable. Portfolio Financings Performance Guarantees - We guarantee the performance of Energy Servers at certain levels of output and efficiency to its customers over the contractual term. The PPA Entities monitor the need for any accruals arising from such guaranties, which are calculated as the difference between committed and actual power output or between natural gas consumption at warranted efficiency levels and actual consumption, multiplied by the contractual rates with the customer. Amounts payable under these guaranties are accrued in periods when the guaranties are not met and are recorded in cost of service revenue in the condensed consolidated statements of operations. We paid $0.1 million and $5.7 million for the three months ended March 31, 2021 and 2020, respectively. Letters of Credit - In 2019, pursuant to the PPA II upgrade of Energy Servers, we agreed to indemnify our financing partner for losses that may be incurred in the event of certain regulatory, legal or legislative development and established a cash-collateralized LC facility for this purpose. As of March 31, 2021, the balance of this cash-collateralized LC was $108.7 million, of which $28.2 million and $80.5 million is recognized as short-term and long-term restricted cash, respectively. Pledged Funds - In 2019, pursuant to the PPA IIIb upgrade of Energy Servers, we have restricted cash of $13.3 million, which has been pledged for a seven-year period to secure our operations and maintenance obligations with respect to the totality of our obligations to the financier. All or a portion of such funds would be released if we meet certain credit rating and/or market capitalization milestones prior to the end of the pledge period. If we do not meet the required criteria within the first five-year period, the funds would still be released to us over the following two years as long as the Energy Servers continue to perform in compliance with our warranty obligations. Contingencies Indemnification Agreements - We enter into standard indemnification agreements with our customers and certain other business partners in the ordinary course of business. Our exposure under these agreements is unknown because it involves future claims that may be made against us but have not yet been made. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. Delaware Economic Development Authority - In March 2012, we entered into an agreement with the Delaware Economic Development Authority to provide a grant of $16.5 million to us as an incentive to establish a new manufacturing facility in Delaware and to provide employment for full time workers at the facility over a certain period of time. The grant contains two types of milestones that we must complete to retain the entire amount of the grant proceeds. The first milestone was to provide employment for 900 full time workers in Delaware by the end of the first recapture period of September 30, 2017. The second milestone was to pay these full-time workers a cumulative total of $108.0 million in compensation by September 30, 2017. There are two additional recapture periods at which time we must continue to employ 900 full time workers and the cumulative total compensation paid by us is required to be at least $324.0 million by September 30, 2023. As of March 31, 2021, we had 462 full time workers in Delaware and paid $162.8 million in cumulative compensation. As of December 31, 2020, we had 424 full time workers in Delaware and paid $152.2 million in cumulative compensation. We have so far received $12.0 million of the grant, which is contingent upon meeting the milestones through September 30, 2023. In the event that we do not meet the milestones, we may have to repay the Delaware Economic Development Authority, up to $1.6 million on September 30, 2021 and up to an additional $2.5 million on September 30, 2023. We repaid $1.5 million of the grant in 2017, and no additional amounts have been repaid since then. As of March 31, 2021, we have recorded $1.3 million in current liabilities and $9.2 million in other long-term liabilities for potential future repayments of this grant. Investment Tax Credits - Our Energy Servers are eligible for federal ITCs that accrued to qualified property under Internal Revenue Code Section 48 when placed into service. However, the ITC program has operational criteria that extend for five years. If the energy property is disposed of or otherwise ceases to be qualified investment credit property before the close of the five-year recapture period is fulfilled, it could result in a partial reduction of the incentives. Energy Servers are purchased by the PPA Entities, other financial sponsors, or customers and, therefore, these parties bear the risk of repayment if the assets placed in service do not meet the ITC operational criteria in the future although in certain limited circumstances we do provide indemnification for such risk. Legal Matters - We are involved in various legal proceedings that arise in the ordinary course of business. We review all legal matters at least quarterly and assess whether an accrual for loss contingencies needs to be recorded. We record an accrual for loss contingencies when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Legal matters are subject to uncertainties and are inherently unpredictable, so the actual liability in any such matters may be materially different from our estimates. If an unfavorable resolution were to occur, there exists the possibility of a material adverse impact on our consolidated financial condition, results of operations or cash flows for the period in which the resolution occurs or on future periods. In July 2018, two former executives of Advanced Equities, Inc., Keith Daubenspeck and Dwight Badger, filed a statement of claim with the American Arbitration Association in Santa Clara, CA, against us, Kleiner Perkins, Caufield & Byers, LLC (“KPCB”), New Enterprise Associates, LLC (“NEA”) and affiliated entities of both KPCB and NEA seeking to compel arbitration and alleging a breach of a confidential agreement executed between the parties on June 27, 2014 (the “Confidential Agreement”). On May 7, 2019, KPCB and NEA were dismissed with prejudice. On June 15, 2019, a second amended statement of claim was filed against us alleging securities fraud, fraudulent inducement, a breach of the Confidential Agreement, and violation of the California unfair competition law. On July 16, 2019, we filed our answering statement and affirmative defenses. On September 27, 2019, we filed a motion to dismiss the statement of claim. On March 24, 2020, the Tribunal denied our motion to dismiss in part, and ordered that claimant’s relief is limited to rescission of the Confidential Agreement or remedies consistent with rescission, and not expectation damages. On September 14, 2020, the Tribunal issued an interim order dismissing the claimant’s remaining claims and requesting further briefing on the issue of prevailing party. On November 10, 2020, the Tribunal issued an order declaring us the prevailing party and requesting a motion for award of attorney’s fees. On March 17, 2021, we received the final award for attorneys fees and costs. On March 26, 2021, we filed a petition in the Northern District of California to confirm the award. In June 2019, Messrs. Daubenspeck and Badger filed a complaint against our Chief Executive Officer ("CEO") and our former Chief Financial Officer ("CFO") in the United States District Court for the Northern District of Illinois asserting nearly identical claims as those in the pending arbitration discussed above. The lawsuit was stayed pending the outcome of the arbitration. The stay was lifted on October 20, 2020. On March 19, 2021 we filed a motion to dismiss the case on several grounds. On May 3, 2021, plaintiffs filed a motion to stay the lawsuit pending the outcome of the petition to confirm the arbitration award in the Northern District of California. We believe the complaint to be without merit and that the issues were previously tried and dismissed in the arbitration. We are unable to estimate any range of reasonably possible losses. In March 2019, the Lincolnshire Police Pension Fund filed a class action complaint in the Superior Court of the State of California, County of Santa Clara, against us, certain members of our senior management, certain of our directors and the underwriters in our July 25, 2018 IPO alleging violations under Sections 11 and 15 of the Securities Act of 1933, as amended (the "Securities Act"), for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. Two related class action cases were subsequently filed in the Santa Clara County Superior Court against the same defendants containing the same allegations; Rodriquez vs Bloom Energy et al. was filed on April 22, 2019 and Evans vs Bloom Energy et al. was filed on May 7, 2019. These cases have been consolidated. Plaintiffs' consolidated amended complaint was filed with the court on September 12, 2019. On October 4, 2019, defendants moved to stay the lawsuit pending the federal district court action discussed below. On December 7, 2019, the Superior Court issued an order staying the action through resolution of the parallel federal litigation mentioned below. We believe the complaint to be without merit and we intend to defend this action vigorously. We are unable to estimate any range of reasonably possible losses. In May 2019, Elissa Roberts filed a class action complaint in the federal district court for the Northern District of California against us, certain members of our senior management team, and certain of our directors alleging violations under Section 11 and 15 of the Securities Act for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. On September 3, 2019, James Hunt was appointed as lead plaintiff and Levi & Korsinsky was appointed as plaintiff’s counsel. On November 4, 2019, plaintiffs filed an amended complaint adding the underwriters in the IPO, claims under Sections 10b and 20a of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and extending the class period to September 16, 2019. On April 21, 2020, plaintiffs filed a second amended complaint adding claims under the Securities Act. The second amended complaint also adds allegations pertaining to the restatement and, as to claims under the Exchange Act, extends the class period through February 12, 2020. On July 1, 2020, we filed a motion to dismiss the second amended complaint and are waiting for a ruling on that motion. We believe the complaint to be without merit and we intend to defend this action vigorously. W e are unable to predict the outcome of this litigation at this time and accordingly are not able to estimate any range of reasonably possible losses. I n September 2019, we received a books and records demand from purported stockholder Dennis Jacob (“Jacob Demand”). The Jacob Demand cites allegations from the September 17, 2019 report prepared by admitted short seller Hindenburg Research. In November 2019, we received a substantially similar books and records demand from the same law firm on behalf of purported stockholder Michael Bolouri (“Bolouri Demand” and, together with the Jacob Demand, the “Demands”). On January 13, 2020, Messrs. Jacob and Bolouri filed a complaint in the Delaware Court of Chancery to enforce the Demands in the matter styled Jacob, et al. v. Bloom Energy Corp. , C.A. No. 2020-0023-JRS. On March 9, 2020, Messrs. Jacob and Bolouri filed an amended complaint in the Delaware Court of Chancery to add allegations regarding the restatement. The court held a one-day trial on December 7, 2020. On February 25, 2021, the Delaware Court of Chancery issued a decision rejecting the Bolouri Demand but granting in part the Jacob Demand allowing limited access to certain books and records pertaining to the allegations made in the Hindenburg Research Report. On March 29, 2021, the Court of Chancery entered a Final Order and Judgment regarding the required production of documents. On April 28, 2021, we produced documents responsive to the Final Order and Judgment to Mr. Jacob. We are unable to estimate any range of reasonably possible losses. In March 2020, Francisco Sanchez filed a class action complaint in Santa Clara County Superior Court against us a lleging certain wage and hour violations under the California Labor Code and Industrial Welfare Commission Wage Orders and that we engaged in unfair business practices under the California Business and Professions Code, and in July 2020 he amended his complaint to add claims under the California Labor Code Private Attorneys General Act. On November 30, 2020, we filed a motion to compel arbitration and the motion was to be heard on March 5, 2021. On February 24, 2021, Mr.Sanchez dismissed the individual and class action claims without prejudice, leaving one cause of action for enforcement of the Private Attorney Generals Act. In April 2021, an amended complaint reflecting these changes was filed with the Santa Clara Superior Court. Given that the case is still in its early stages, we are unable to estimate any range of reasonably possible losses.

The effective tax rate for the three months ended March 31, 2021 and 2020 is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.

Earnings Per Share [Abstract]
Net Loss per Share Attributable to Common StockholdersNet Loss per Share Available to Common Stockholders Net loss per share (basic) available to common stockholders is calculated by dividing net loss available to common stockholders by the weighted-average shares of common stock outstanding for the period. Net loss per share is the same for each class of common stock as they are entitled to the same liquidation and dividend rights. As a result, net loss per share (basic) and net loss per share (diluted) available to common stockholders are the same for both Class A and Class B common stock and are combined for presentation. Net loss per share (diluted) is computed by using the if-converted method when calculating the potentially dilutive effect, if any, of our convertible notes. Net loss per share (diluted) available to common stockholders is then calculated by dividing the resulting adjusted net loss available to common stockholders by the combined weighted-average number of fully diluted common shares outstanding. There were no adjustments to net loss available to common stockholders (diluted). Equally, there were no adjustments to the weighted average number of outstanding shares of common stock (basic) in arriving at the weighted average number of outstanding shares (diluted), as such adjustments would have been antidilutive. The following table sets forth the computation of our net loss per share available to common stockholders, basic and diluted (in thousands, except per share amounts): Three Months Ended 2021 2020 Numerator: Net loss available to Class A and Class B common stockholders $ (24,889) $ (75,949) Denominator: Weighted average shares of common stock, basic and diluted 170,745 123,763 Net loss per share available to Class A and Class B common stockholders, basic and diluted $ (0.15) $ (0.61) The following common stock equivalents (in thousands) were excluded from the computation of our net loss per share available to common stockholders, diluted, for the three months presented as their inclusion would have been antidilutive: Three Months Ended 2021 2020 Convertible notes $ 14,187 $ 40,723 Stock options and awards 8,625 4,993 $ 22,812 $ 45,716

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)3 Months Ended
Mar. 31, 2021
Accounting Policies [Abstract]
Basis of PresentationBasis of Presentation We have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"), and as permitted by those rules, including all disclosures required by generally accepted accounting principles as applied in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated upon consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. As disclosed in the 2020 Annual Report on Form 10-K, effective on December 31, 2020, we lost our emerging growth company ("EGC") status which accelerated the adoption of ASC 842 - Leases . As a result, we adjusted our previously reported consolidated financial statements effective January 1, 2020.
Principles of ConsolidationPrinciples of Consolidation These condensed consolidated financial statements reflect our accounts and operations and those of our subsidiaries in which we have a controlling financial interest. We use a qualitative approach in assessing the consolidation requirement for each of our variable interest entities ("VIEs"), which we refer to as a tax equity partnership (each such VIE, also referred to as our power purchase agreement entities ("PPA Entities")). This approach focuses on determining whether we have the power to direct those activities of the PPA Entities that most significantly affect their economic performance and whether we have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the PPA Entities. For all periods presented, we have determined that we are the primary beneficiary in all of our operational PPA Entities, as discussed in Note 11 - Portfolio Financings . We evaluate our relationships with the PPA Entities on an ongoing basis to ensure that we continue to be the primary beneficiary. All intercompany transactions and balances have been eliminated upon consolidation.
Use of EstimatesUse of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. The most significant estimates include the determination of the stand-alone selling price, including material rights estimates, inventory valuation, specifically excess and obsolescence provisions for obsolete or unsellable inventory and, in relation to property, plant and equipment (specifically Energy Servers), assumptions relating to economic useful lives and impairment assessments. Other accounting estimates include variable consideration relating to product performance guaranties, lease and non-lease components and related financing obligations such as incremental borrowing rates, estimated output, efficiency and residual value of the Energy Servers, product performance warranties and guaranties and extended maintenance, derivative valuations, estimates for recapture of the U.S. investment tax credit ("ITC") and similar federal tax benefits, estimates relating to contractual indemnities provisions, estimates for income taxes and deferred tax asset valuation allowances, and stock-based compensation costs. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including sales, expenses, our allowance for doubtful accounts, stock-based compensation, the carrying value of our long-lived assets, inventory, financial assets, and valuation allowances for tax assets, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning the COVID-19 pandemic and the actions taken to contain it or treat it, as well as the economic impact on local, regional, national and international customers, suppliers and markets. We have made estimates of the impact of COVID-19 within our condensed consolidated financial statements and there may be changes to those estimates in future periods as new information becomes available. Actual results could differ materially from these estimates under different assumptions and conditions.
Foreign Currency TransactionsForeign Currency Transactions The functional currencies of most of our foreign subsidiaries are the U.S. dollar since the subsidiaries are considered financially and operationally integrated with their domestic parent. For these subsidiaries, the foreign currency monetary assets and liabilities are remeasured into U.S. dollars at end-of-period exchange rates. Any currency transaction gains and losses are included as a component of other expense in our condensed consolidated statements of operations. The functional currency of our joint venture in the Republic of Korea is the local currency, the South Korean won ("KRW"), since the joint venture is financially independent of its U.S. parent and the KRW is the currency in which the joint venture generates and expends cash. Assets and liabilities of this entity are translated at the rate of exchange at the balance sheet date. Revenues and expenses are translated at the weighted average rate of exchange during the period. For this entity, translation adjustments resulting from the process of translating the KRW financial statements into U.S dollars are included in other comprehensive loss. Translation adjustments attributable to noncontrolling interests are allocated to and reported as part of the noncontrolling interests in the condensed consolidated financial statements.
Recent Accounting PronouncementsRecent Accounting Pronouncements Other than the adoption of the accounting guidance mentioned below, there have been no other significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements. Accounting Guidance Implemented in 2021 In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06"). The new standard simplifies the accounting for convertible instruments by eliminating the conversion option separation model for convertible debt that can be settled in cash and by eliminating the measurement model for beneficial conversion features. The guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted as early as fiscal years (including interim periods) beginning after December 15, 2020. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. There will no longer be a debt discount representing the difference between the carrying value, excluding issuance costs, and the principal of the convertible debt instrument and, as a result, there will no longer be interest expense from the amortization of the debt discount over the term of the convertible debt instrument. The amendments in this update also require the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. We elected to early adopt ASU 2020-06 as of January 1, 2021 using the modified retrospective transition method, which resulted in a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. Prior period condensed consolidated financial statements were not restated upon adoption. Upon adoption of ASU 2020-06, the Company combined the previously separated equity component with the liability component of our 2.5% Green Convertible Senior Notes due August 2025. These components are now together classified as Recourse debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and will be amortized as interest expense. Accordingly, we recorded a decrease to Accumulated deficit of $5.3 million, a decrease to Additional paid-in capital of $126.8 million, and an increase to Recourse debt, non-current of approximately $121.5 million. There is no deferred tax impact related to the adoption of ASU 2020-06 due to our full valuation allowance. Accounting Guidance Not Yet Adopted Cessation of LIBOR - In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"), which provides optional expedients for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the London
