Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the SEC’s regulations for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements.
Revision of Previously Issued Unaudited Financial Information | Certain prior period financial information included in these unaudited interim consolidated financial statements has been revised to correct immaterial errors. See Note 13, Revision of Previously Issued Unaudited Financial Information, for additional information. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the consolidated financial statements included in the Company’s 2025 Form 10-K. Interim results are not necessarily indicative of results for a full year. In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary for a fair statement of the Company’s consolidated financial position as of June 30, 2026 and December 31, 2025, and results of operations, comprehensive income (loss) and cash flows for the three and six months ended June 30, 2026 and 2025.
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amounts of net earnings during the reporting periods. Actual results could be different from these estimates.
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include highly liquid investments with an original maturity of three months or less at the time of purchase.Restricted cash consists primarily of funds held to satisfy the requirements of certain debt agreements and funds held within the Company’s facilities that are restricted in their use.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards Effective January 1, 2026, the Company adopted ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendment clarifies when software costs should be capitalized and requires certain disclosures for all capitalized internal-use software costs. The Company adopted ASU 2025-06 prospectively and the adoption had no material impact on the Company’s financial statements. Effective January 1, 2026, the Company adopted ASU No. 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract. The amendment expands the derivative scope exceptions and clarifies when an entity should apply the guidance in ASC 606, Revenue from Contracts with Customers, to contracts with share-based noncash consideration from a customer for the transfer of goods or services. The Company adopted ASU 2025-07 prospectively, and the adoption had no material impact on the Company’s financial statements. Recent Accounting Standards Not Yet Adopted In May 2026, the FASB issued ASU 2026-02, Environmental Credits and Environmental Credit Obligations (Topic 818), which establishes guidance for the recognition, measurement, presentation and disclosure of environmental credits and environmental credit obligations. The guidance is effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual periods. The amendment must be applied retrospectively through a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the annual reporting period of adoption. Early adoption is permitted. As of June 30, 2026, the Company has not elected to early adopt the standard and is evaluating the effect of the new guidance on its consolidated financial statements.
Concentration of Credit Risk | Concentration of Credit Risk In addition to the credit risk discussion as disclosed under Item 15 — Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements included in the Company’s 2025 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company’s financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) monitoring of counterparties’ credit limits on an as needed basis; (iii) as applicable, the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties. Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. A significant portion of these energy-related commodity contracts are with utilities with strong credit quality and public utility commission or other regulatory support. However, such regulated utility counterparties can be impacted by changes in government regulations or adverse financial conditions, which the Company is unable to predict. Certain subsidiaries of the Company sell the output of their facilities to PG&E, a significant counterparty of the Company, under long-term PPAs, and PG&E’s credit rating is below investment-grade.
