Description of business and basis of presentation | Description of Business and Basis of Presentation Description of Business Tecogen Inc. (together with its subsidiaries, “we,” “our,” or “us,” or “Tecogen”) designs, manufactures, markets, and maintains high efficiency, ultra-clean cogeneration products. These include natural gas engine driven combined heat and power (CHP) systems, chillers and heat pumps for multi-family residential, commercial, recreational and industrial use. We are known for products that provide customers with substantial energy savings, resiliency from utility power outages and for significantly reducing a customer’s carbon footprint. Our products are sold with our patented Ultera® emissions technology which nearly eliminates all criteria pollutants such as nitrogen oxide ("NOx") and carbon monoxide ("CO"). We developed Ultera® for other applications including stationary engines and forklifts. We were incorporated in the State of Delaware on September 15, 2000. We have wholly-owned subsidiaries American DG Energy, Inc. ("ADGE") and Tecogen CHP Solutions, Inc., and we own a 51% interest in American DG New York, LLC ("ADGNY"), a joint venture. ADGE and ADGNY distribute, own, and operate clean, on-site energy systems that produce electricity, hot water, heat and cooling. ADGE owns the equipment that it installs at a customer’s facility and sells the energy produced by its systems to the customer on a long-term contractual basis. Our operations are comprised of three business segments: • our Products segment, which designs, manufactures and sells industrial and commercial cogeneration systems; • our Services segment, which provides operations and maintenance ("O&M") services and turn-key installation for our products under long term service contracts, and • our Energy Production segment, which sells energy in the form of electricity, heat, hot water and cooling to our customers under long-term energy sales agreements. The majority of our customers are located in regions with the highest utility rates, typically California, the Midwest and the Northeast. On July 20, 2022, we announced our intention to increase focus on opportunities relating to Controlled Environment Agriculture (CEA). Tecogen believes that CEA offers an exciting opportunity to apply the company’s expertise in clean cooling, power generation, and greenhouse gas reduction to address critical issues affecting food and energy security. Our common stock is quoted on OTC Markets Group, Inc.'s OTCQX Best Market tier and trades under the symbol "TGEN." On May 18, 2017, the Company acquired 100% of the outstanding common stock of American DG Energy Inc., formerly a related entity, in a stock-for-stock merger. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The condensed consolidated balance sheet at December 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in Tecogen's Annual Report on Form 10-K for the year ended December 31, 2022. The accompanying unaudited condensed consolidated financial statements include our accounts and the accounts of entities in which we have a controlling financial interest. Those entities include our wholly-owned subsidiaries American DG Energy Inc., Tecogen CHP Solutions, Inc., and a joint venture, American DG New York, LLC, in which American DG Energy Inc. holds a 51% interest. Investments in partnerships and companies in which we do not have a controlling financial interest but where we have significant influence are accounted for under the equity method. Any intercompany transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Income Taxes The provisions for income taxes in the accompanying unaudited consolidated statements of operations differ from that which would be expected by applying the federal statutory tax rate primarily due to losses for which no benefit is recognized. Employee Retention Credit On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law providing numerous tax provisions and other stimulus measures, including an employee retention credit (“ERC”), which is a refundable tax credit against certain employment taxes. The Taxpayer Certainty and Disaster Tax Relief Act of 2020 and the American Rescue Plan Act of 2021 extended and expanded the availability of the ERC. As a result of our election to use an alternative quarter, we qualified for the ERC in the first, second and third quarters of 2021 because our gross receipts decreased by more than 20% from the first, second and third quarters of 2019. As a result of averaging 100 or fewer full-time employees in 2019, all wages paid to employees in the first, second and third quarters of 2021, excluding the wages applied to the Paycheck Protection Program Second Draw Loan, were eligible for the ERC. During the three months ended June 30, 2021, we recorded an ERC benefit for the first and second quarters of 2021 of $713,269 and, in the three months ended September 30, 2021 we recorded an ERC benefit for the third quarter of 2021 of $562,752, respectively, in other income (expense), net in the our condensed consolidated statements of operations. On April 14, 2022, we received $564,027 from the Internal Revenue Service representing the ERC claim for the third quarter of 2021 and $1,275 of accrued interest. We received $667,121 from the Internal Revenue Service on January 12, 2023 in payment of the ERC claimed from the first and second quarters of 2021 and $15,775 of accrued interest, which is reported in other income (expense) in our condensed consolidated statements of operations for the three months ended March 31, 2023. A current receivable in the amount of $46,148 is included in our condensed consolidated balance sheet as of March 31, 2023. We expect to receive the remaining balance in 2023. |

Revenue Recognition [Abstract] | |
Revenue | Revenue Revenue is recognized when performance obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of our products, services and energy production. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services or energy to customers. Shipping and handling fees billed to customers in a sales transaction are recorded in revenue and shipping and handling costs incurred are recorded in cost of sales. We have elected to exclude from revenue any value-added sales and other taxes which we collect concurrent with revenue-producing activities. These accounting policy elections are consistent with the manner in which we historically recorded shipping and handling fees and value-added taxes. Incremental costs incurred by us to obtain a contract with a customer are negligible, if any, and are expensed ratably in proportion to the related revenue recognized. Disaggregated Revenue In general, our business segmentation is aligned according to the nature and economic characteristics of our products and customer relationships and provides meaningful disaggregation of each business segment's results of operations. The following table further disaggregates our revenue by major source by segment for the three months ended March 31, 2023 and 2022. Three Months Ended March 31, 2023 Products Services Energy Production Total Products $ 1,710,136 $ — $ — $ 1,710,136 Maintenance services — 3,136,173 — 3,136,173 Energy production — — 533,509 533,509 Total revenue $ 1,710,136 $ 3,136,173 $ 533,509 $ 5,379,818 Three Months Ended March 31, 2022 Products Services Energy Production Total Products $ 3,939,481 $ — $ — $ 3,939,481 Installation services — 20,109 — 20,109 Maintenance services — 2,897,171 — 2,897,171 Energy production — — 581,562 581,562 Total revenue $ 3,939,481 $ 2,917,280 $ 581,562 $ 7,438,323 Products Segment Products. Our Product revenues include cogeneration systems that supply electricity and hot water, chillers that provide air-conditioning and hot water and engineered accessories, which consist of ancillary products and parts necessary to install a cogeneration unit including integration into the customers’ existing electrical and mechanical systems. We refer to the package of engineered accessories and engineering and design services necessary for the customers' installation of a cogeneration unit as light installation services. We transfer control and generally recognize a sale when we ship a product from our manufacturing facility at which point the customer takes ownership of the product. Payment terms on product sales are generally 30 days. We recognize revenue in certain circumstances before delivery to the customer has occurred (commonly referred to as bill and hold transactions). We recognize revenue related to such transactions once, among other things, the customer has made a written fixed commitment to purchase the product(s) under normal billing and credit terms, the customer has requested the product(s) be held for future delivery as scheduled and designated by them, risk of ownership has been assumed by the customer, and the product(s) are tagged as sold and segregated for storage awaiting further direction from the customer. Due to the infrequent nature and duration of bill and hold arrangements, the value associated with custodial storage services is deemed immaterial in the context of the contract and in total, and accordingly, none of the transaction price is allocated to such service. Depending on the product and terms of the arrangement, we may defer the recognition of a portion of the transaction price received because we have to satisfy a future obligation (e.g., product start-up service). Amounts allocated to product start-up services are recognized as revenue when the start-up service has been completed. We use an observable selling price to determine standalone selling prices where available and either a combination of an adjusted market assessment approach, an expected cost plus a margin approach, and/or a residual approach to determine the standalone selling prices for separate performance obligations as a basis for allocating contract consideration when an observable selling price is not available. Amounts received but not recognized pending completion of performance are recognized as contract liabilities and are recorded as deferred revenue along with deposits by customers. Services Segment Maintenance Services. Maintenance services are provided under either long-term maintenance contracts or time and material maintenance contracts. Revenue under time and material maintenance contracts is recognized when the maintenance service is completed. Revenue under long-term maintenance contracts is recognized either ratably over the term of the contract where the contract price is fixed or when the periodic maintenance activities are completed where the invoiced cost to the customer is based on run hours or kilowatts produced in a given period. We use an output method to measure progress towards completion of our performance obligation which results in the recognition of revenue on the basis of a direct measurement of the value to the customer of the services transferred to date relative to the remaining services promised under the contract. We use the practical expedient at ASC 606-10-55-18 of recognizing revenue in an amount equal to the amount we have the right to invoice the customer under the contract. Payment terms for maintenance services are generally 30 days. Installation Services. We provide both complete turnkey installation services which typically include all necessary engineering and design, labor, subcontract labor to install a cogeneration unit including integration into the customers’ existing electrical and mechanical systems. Under complete turnkey installation service contracts revenue is recognized over time using the percentage-of-completion method determined on a cost to cost basis. Our performance obligation under such contracts are satisfied progressively over time as enhancements are made to customer owned and controlled properties. We measure progress towards satisfaction of the performance obligation based on an input method based on cost which we believe is the most faithful depiction of the transfer of products and services to the customer under these contracts. When the financial metrics of a contract indicate a loss, our policy is to record the entire expected loss as soon as it is known. Contract costs and profit recognized to date under the percentage-of-completion method in excess of billings are recognized as contract assets and are recorded as unbilled revenue. Billings in excess of contract costs and profit are recognized as contract liabilities and are recorded as deferred revenue. Generally billings under complete turnkey installation contracts are made when contractually determined milestones of progress have been achieved, with payment terms generally being 30 days. Our installation services revenue decreased significantly in three months March 31, 2023 and is likely to continue to remain low due to our strategy to focus on higher margin segments of our business. Energy Production Segment Energy Production. Revenue from energy contracts is recognized when electricity, heat, hot and/or chilled water is produced by our owned on-site cogeneration systems. Each month we bill the customer and recognize revenue for the various forms of energy delivered, based on meter readings which capture the quantity of the various forms of energy delivered in a given month, under a contractually defined formula which takes into account the current month's cost of energy from the local power utility. As the various forms of energy delivered by us under energy production contracts are simultaneously delivered and consumed by the customer, our performance obligation under these contracts is considered to be satisfied over time. We use an output method to measure progress towards completion of our performance obligation which results in the recognition of revenue on the basis of a direct measurement of the value to the customer of the services transferred to date relative to the remaining services promised under the contract. We use the practical expedient at ASC 606-10-55-18 of recognizing revenue in an amount equal to that amount to which we have the right to invoice the customer under the contract. Payment terms on invoices under these contracts are generally 30 days. Contract Balances The timing of revenue recognition, billings and cash collections result in billed accounts receivable, unbilled revenue (contract assets) and deferred revenue, consisting of customer deposits and billings in excess of revenue recognized (contract liabilities) on the condensed consolidated balance sheets. We did not recognize any revenue during the three months ended March 31, 2023 that was included in unbilled revenue at the end of the period. Approximately $16,428 was billed in this period that had been recognized as revenue in previous periods. Revenue recognized during the three ended months March 31, 2023 that was included in deferred revenue at the beginning of the period was approximately $136,640. Remaining Performance Obligations Remaining performance obligations related to ASC 606 represent the aggregate transaction price allocated to performance obligations with an original contract term of greater than one year, excluding certain maintenance contracts and all energy production contracts where a direct measurement of the value to the customer is used as a method of measuring progress towards completion of our performance obligation. Exclusion of these remaining performance obligations is due in part to the inability to quantify values based on unknown future levels of delivery and in some cases rates used to invoice customers. Remaining performance obligations therefore consist of unsatisfied or partially satisfied performance obligations related to fixed price maintenance contracts and installation contracts. As of March 31, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $2.3 million. We expect to recognize revenue of approximately 98.5% of the remaining performance obligations over the next 24 months, 90.1% recognized in the first 12 months and 8.4% recognized over the subsequent 12 months, and the remainder recognized thereafter. |

Discontinued Operations and Disposal Groups [Abstract] | |
Sale of Energy Producing Assets and Goodwill Impairment | Sale of Energy Producing Assets and Goodwill ImpairmentDuring the first quarter of 2019 we recognized two individual sales of energy producing assets, for a total of eight power purchase agreements, including the associated energy production contracts for total consideration of $7 million. In connection with these assets sales, we entered into agreements with the purchaser to maintain and operate the assets over the remaining periods of the associated energy production contracts (through August 2033 and January 2034, respectively) in exchange for monthly maintenance and operating fees. These agreements contain provisions whereby we have guaranteed to the purchaser a minimum level or threshold of cash flows from the associated energy production contracts. Actual results are compared to the minimum threshold bi-annually and we are contractually obligated to reimburse any shortfall to the purchaser. To the extent actual cash flow results exceed the minimum threshold, we are entitled to fifty percent of such excess under the agreements. Based upon an analysis of these energy producing assets expected future performance, as of March 31, 2023, we do not expect to make any material payments under the guarantee. At March 31, 2023, we were due $22,229 under the energy production contracts, representing outstanding accounts receivable balances that were due from the purchaser's customers which were past due at December 31, 2022 and have since been collected. We expect to receive these funds in the third quarter of 2023 when the bi-annnual reconciliation for the period ended June 30, 2023 is prepared. The foregoing agreements also contain provisions whereby we have agreed to make whole the purchaser in the event the counterparty to the energy production contract(s) defaults on or otherwise terminates before the stated expiration of the energy production contract. Should we be required to make whole the purchaser under such provisions, we would be entitled to seek recovery from the counterparty to the energy production contract(s) under a similar provision contained in those contracts in respect of early termination. |

Leases [Abstract] | |
Leases | Leases Our leases principally consist of operating leases related to our corporate office, field offices, and our research, manufacturing and storage facilities. At inception, we determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of our lease agreements contain lease components (e.g. minimum rent payments) and non-lease components (e.g. maintenance, labor charges, etc.). We account for each component separately based on the estimated standalone price of each component. Operating leases are included in Right-of-use assets, Lease obligations, current and Lease obligations, long term on the condensed consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term and using an incremental borrowing rate consistent with the lease terms or implicit rates, when readily determinable. For those leases where it is reasonably certain at the commencement date that we will exercise the option to extend the lease, then the lease term will include the lease extension term. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. Lease expense for operating leases, which principally consist of fixed payments for base rent, is recognized on a straight-line basis over the lease term. Lease expense for the three months ended March 31, 2023 and 2022 was $189,715 and and $196,979, respectively. Supplemental information related to leases for the three months ended March 31, 2023 was as follows: Three Months Ended March 31, 2023 March 31, 2022 Cash paid for amounts included in the measurement of operating lease liabilities $ 184,072 $ 181,661 Right-of-use assets obtained in exchange for operating lease liabilities $ — $ — Weighted-average remaining lease term - operating leases 3.60 years 3.80 years Weighted-average discount rate - operating leases 6 % 6 % Supplemental information related to operating leases as of March 31, 2023 and December 31, 2022 was as follows: March 31, 2023 December 31, 2022 Operating leases Right-of-use assets $ 1,084,033 $ 1,245,549 Operating lease liability, current $ 646,805 $ 687,589 Operating lease liability, long-term 496,526 623,452 Total operating lease liability $ 1,143,331 $ 1,311,041 Future minimum lease commitments under non-cancellable operating leases as of March 31, 2023 were as follows: Operating Leases Year 1 $ 691,899 Year 2 146,956 Year 3 120,763 Year 4 94,023 Year 5 53,092 Thereafter 157,648 Total lease payments 1,264,381 Less: imputed interest 121,050 Total $ 1,143,331 The lease on our headquarters located in Waltham, Massachusetts which consists of approximately 43,000 square feet of manufacturing, storage and office space, expires on March 31, 2024. Currently, our monthly base rent is $44,254. On March 31, 2023, we entered into two lease agreements for two adjoining buildings, located in Billerica, Massachusetts, containing approximately 26,412 square feet of manufacturing, storage and offices space to serve as our headquarters and manufacturing facilities. Under the terms of the leases, which have initial lease terms of five (5) years with two successive options to renew for additional terms of five (5) years, both leases commence on January 1, 2024 and require payment of the base rent, plus real estate taxes and common maintenance expenses. Our costs for initial improvements required to the leased premises is estimated to range between $1,000,000 and $1,250,000. The estimated straight-line rent expense for the initial term of the lease is approximately $24,800. In accordance with ASC 842-20-30-1, we will record the lease liability and right-of-use asset using the discount rate for the lease upon the lease commencement date. |

Stock-Based Compensation | Stock-Based Compensation Stock-Based Compensation We adopted a 2006 Stock Option and Incentive Plan, or the Plan, under which the Board of Directors may grant incentive or non-qualified stock options and stock grants to key employees, directors, advisors and consultants. The Plan was amended at various dates by the Board of Directors to increase the reserved shares of common stock issuable under the Amended Plan to 3,838,750 as of March 31, 2023, and in June 2017 stockholders approved an amendment to extend the termination date of the Plan to January 1, 2026. Stock options vest based upon the terms within the individual option grants, with an acceleration of the unvested portion of such options upon a change in control event, as defined in the Amended Plan. The options are not transferable except by will or domestic relations order. The option price per share under the Amended Plan cannot be less than the fair market value of the underlying shares on the date of the grant. The number of shares remaining available for future issuance under the Amended Plan as of March 31, 2023 was 150,893. During the three months ended March 31, 2023, we did not grant any options to purchase shares of common stock under the Amended Plan. We adopted the 2022 Stock Incentive Plan (the "2022 Plan"), under which the Board of Directors may grant incentive or non-qualified stock options and stock grants to key employees, directors, advisors and consultants. We have reserved 3,800,000 shares of our common stock for issuance pursuant to awards under the 2022 Plan. The adoption of the 2022 Plan was approved by our shareholders on June 9, 2022. Under the 2022 Plan, stock options vest based upon the terms within the individual option grants, with an acceleration of the unvested portion of such options upon a change in control event, as defined in the 2022 Plan. The options are not transferable except by will or domestic relations order. The option price per share under the 2022 Plan cannot be less than the fair market value of the underlying shares on the date of the grant. The number of shares remaining available for future issuance under the Plan as of March 31, 2023 was 3,600,000. During the three months ended March 31, 2023, we did not grant any options to purchase shares of common stock under the 2022 Plan.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The fair value topic of the FASB Accounting Standards Codification defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities. We currently do not have any Level 1 financial assets or liabilities. Level 2 - Observable inputs other than quoted prices included in Level 1. Level 2 inputs include quoted prices for identical assets or liabilities in non-active markets, quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for substantially the full term of the asset or liability. We have Level 2 financial assets and liabilities as provided below. Level 3 - Unobservable inputs reflecting management’s own assumptions about the input used in pricing the asset or liability. We do not currently have any Level 3 financial assets or liabilities. The following tables presents the asset reported in "other assets" in the consolidated balance sheet measured at its fair value on a recurring basis as of March 31, 2023 and 2022 by level within the fair value hierarchy.

That measurement is equal to the quoted market closing price at period end. Since this security is not actively traded we classify it as Level 2. The following table summarizes changes in Level 2 assets which are comprised of marketable equity securities for the three months ended March 31, 2023 and 2022: Fair value at December 31, 2022 $ 93,744 Unrealized gains — Fair value at March 31, 2023 $ 93,744 Fair value at December 31, 2021 $ 74,995 Unrealized gains 37,497 Fair value at March 31, 2022 $ 112,492 |

Subsequent Events | Subsequent Events We have evaluated events through the date of this filing, and, except as described below, have determined that no material subsequent events occurred that would require recognition in the consolidated financial statements or disclosure in the notes thereto. On March 15, 2023, we entered into an Agreement with Aegis Energy Services, LLC (“Aegis”) regarding the assignment and assumption of certain maintenance agreements, the purchase and sale of certain assets, and related matters (the “Agreement”) pursuant to which we agreed to assume Aegis’ rights and obligations arising on or after April 1, 2023 under Maintenance Agreements for 202 cogeneration systems, and acquire certain vehicles and inventory used in connection with the performance of maintenance services. On April 1, 2023, we closed on the agreement with Aegis and acquired certain Aegis vehicles for $170,000, and hired eight (8) former Aegis employees who will continue to provide maintenance services relating to the cogeneration systems. As agreed, Aegis will provide transitional services relating to the assumed Maintenance Agreements. between the closing and June 30, 2023, we will acquire from Aegis inventory used to provide maintenance services in exchange for a credit of $300,000 to be used for purchases by Aegis of our cogeneration equipment on or before June 30, 2023. Following the closing, for a period of up to seven years, we will pay Aegis a portion of the revenue collected for maintenance services provided pursuant to the assumed Maintenance Agreements. We also have the right to assume Aegis’ remaining Maintenance Agreements for cogeneration systems on the same terms and conditions but effective December 31, 2023 to the extent that Aegis is permitted to assign such agreements to us in accordance with the terms of such agreements. Management is in the process of evaluating the accounting impact of the Aegis agreement. |

Principles of Consolidation and Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The condensed consolidated balance sheet at December 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in Tecogen's Annual Report on Form 10-K for the year ended December 31, 2022. |
Use of Estimates | Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates |
Income Taxes | Income Taxes The provisions for income taxes in the accompanying unaudited consolidated statements of operations differ from that which would be expected by applying the federal statutory tax rate primarily due to losses for which no benefit is recognized. |

Our Product revenues include cogeneration systems that supply electricity and hot water, chillers that provide air-conditioning and hot water and engineered accessories, which consist of ancillary products and parts necessary to install a cogeneration unit including integration into the customers’ existing electrical and mechanical systems. We refer to the package of engineered accessories and engineering and design services necessary for the customers' installation of a cogeneration unit as light installation services. We transfer control and generally recognize a sale when we ship a product from our manufacturing facility at which point the customer takes ownership of the product. Payment terms on product sales are generally 30 days. We recognize revenue in certain circumstances before delivery to the customer has occurred (commonly referred to as bill and hold transactions). We recognize revenue related to such transactions once, among other things, the customer has made a written fixed commitment to purchase the product(s) under normal billing and credit terms, the customer has requested the product(s) be held for future delivery as scheduled and designated by them, risk of ownership has been assumed by the customer, and the product(s) are tagged as sold and segregated for storage awaiting further direction from the customer. Due to the infrequent nature and duration of bill and hold arrangements, the value associated with custodial storage services is deemed immaterial in the context of the contract and in total, and accordingly, none of the transaction price is allocated to such service. Depending on the product and terms of the arrangement, we may defer the recognition of a portion of the transaction price received because we have to satisfy a future obligation (e.g., product start-up service). Amounts allocated to product start-up services are recognized as revenue when the start-up service has been completed. We use an observable selling price to determine standalone selling prices where available and either a combination of an adjusted market assessment approach, an expected cost plus a margin approach, and/or a residual approach to determine the standalone selling prices for separate performance obligations as a basis for allocating contract consideration when an observable selling price is not available. Amounts received but not recognized pending completion of performance are recognized as contract liabilities and are recorded as deferred revenue along with deposits by customers. Services Segment Maintenance Services. Maintenance services are provided under either long-term maintenance contracts or time and material maintenance contracts. Revenue under time and material maintenance contracts is recognized when the maintenance service is completed. Revenue under long-term maintenance contracts is recognized either ratably over the term of the contract where the contract price is fixed or when the periodic maintenance activities are completed where the invoiced cost to the customer is based on run hours or kilowatts produced in a given period. We use an output method to measure progress towards completion of our performance obligation which results in the recognition of revenue on the basis of a direct measurement of the value to the customer of the services transferred to date relative to the remaining services promised under the contract. We use the practical expedient at ASC 606-10-55-18 of recognizing revenue in an amount equal to the amount we have the right to invoice the customer under the contract. Payment terms for maintenance services are generally 30 days. Installation Services. We provide both complete turnkey installation services which typically include all necessary engineering and design, labor, subcontract labor to install a cogeneration unit including integration into the customers’ existing electrical and mechanical systems. Under complete turnkey installation service contracts revenue is recognized over time using the percentage-of-completion method determined on a cost to cost basis. Our performance obligation under such contracts are satisfied progressively over time as enhancements are made to customer owned and controlled properties. We measure progress towards satisfaction of the performance obligation based on an input method based on cost which we believe is the most faithful depiction of the transfer of products and services to the customer under these contracts. When the financial metrics of a contract indicate a loss, our policy is to record the entire expected loss as soon as it is known. Contract costs and profit recognized to date under the percentage-of-completion method in excess of billings are recognized as contract assets and are recorded as unbilled revenue. Billings in excess of contract costs and profit are recognized as contract liabilities and are recorded as deferred revenue. Generally billings under complete turnkey installation contracts are made when contractually determined milestones of progress have been achieved, with payment terms generally being 30 days. Our installation services revenue decreased significantly in three months March 31, 2023 and is likely to continue to remain low due to our strategy to focus on higher margin segments of our business. Energy Production Segment Energy Production. Revenue from energy contracts is recognized when electricity, heat, hot and/or chilled water is produced by our owned on-site cogeneration systems. Each month we bill the customer and recognize revenue for the various forms of energy delivered, based on meter readings which capture the quantity of the various forms of energy delivered in a given month, under a contractually defined formula which takes into account the current month's cost of energy from the local power utility. |
