Basis of Presentation [Abstract]
Basis of Presentation	NOTE 1: BASIS OF PRESENTATION Nature of Business Portland General Electric Company (PGE or the Company) is a single, vertically-integrated electric utility engaged in the generation, purchase, transmission, distribution, and retail sale of electricity in the State of Oregon (State). The Company also participates in the wholesale market by purchasing and selling electricity, natural gas, and environmental credits in an effort to meet the needs of, and obtain reasonably-priced power for, its retail customers, manage risk, and administer its long-term wholesale contracts. In addition, PGE performs wholesale market services for third parties in the region. The Company develops products and service offerings for the benefit of retail and wholesale customers. PGE operates as a single segment, with revenues and costs related to its business activities recorded and analyzed on a total electric operations basis. The Company owns unregulated, non-utility real estate comprised primarily of PGE’s corporate headquarters. The Company’s corporate headquarters is located in Portland, Oregon and its approximately 4,000 square mile, State-approved service area, entirely within the State, encompasses 51 incorporated cities. As of June 30, 2026, PGE served 962,000 retail customers within a service area of approximately 2 million residents. PGE is subject to the jurisdiction of the Public Utility Commission of Oregon (OPUC) with respect to retail prices, utility services, accounting policies and practices, issuances of securities, and certain other matters. Retail prices are based on the Company’s cost to serve customers, including an opportunity to earn a reasonable rate of return, as determined by the OPUC. The Company is also subject to regulation by the Federal Energy Regulatory Commission (FERC) in matters related to wholesale energy transactions, transmission services, reliability standards, natural gas pipelines, hydroelectric project licensing, accounting policies and practices, short-term debt issuances, and certain other matters. Condensed Consolidated Financial Statements These condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such regulations, although PGE believes that the disclosures provided are adequate to make the interim information presented not misleading. The financial information included herein as of and for the three and six months ended June 30, 2026 and 2025 is unaudited; however, in the opinion of management, such information reflects all adjustments necessary to fairly present the condensed consolidated financial position, condensed consolidated income and comprehensive income, and condensed consolidated cash flows of the Company for these interim periods. All such adjustments are of a normal recurring nature, unless otherwise noted. The financial information as of December 31, 2025 is derived from the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2025, included in Item 8 of PGE’s Annual Report on Form 10-K, filed with the SEC on February 17, 2026, which should be read in conjunction with the interim unaudited Financial Statements. Comprehensive Income No material change occurred in Other comprehensive income in the three and six months ended June 30, 2026 and 2025. Use of Estimates The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of gain or loss contingencies, as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results experienced by the Company could differ materially from those estimates. Certain costs are estimated for the full year and allocated to interim periods based on estimates of operating time expired, benefit received, or activity associated with the interim period; accordingly, such costs may not be reflective of amounts to be recognized for a full year. Due to seasonal fluctuations in electricity sales, as well as the price of wholesale electricity and natural gas, interim financial results do not necessarily represent those to be expected for the year. Recent Accounting Pronouncements In November 2024, the FASB issued Accounting Standards Update (ASU) 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires additional disclosure, in the notes to financial statements, of specified information about certain costs and expenses. For calendar year-end entities, the update will be effective for annual periods beginning on January 1, 2027. Early adoption is permitted. PGE is assessing the impact of adoption on the consolidated financial statements and does not plan to early adopt the standard. In December 2025, the FASB issued ASU 2025-10 Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. ASU 2025-10 adds guidance to Accounting Standards Codification (ASC) 832 on the recognition, measurement, and presentation of government grants. For calendar year-end entities, the update will be effective for annual periods beginning on January 1, 2029. Early adoption is permitted. PGE is assessing the impact of adoption on the consolidated financial statements and does not plan to early adopt the standard. In May 2026, the FASB issued ASU 2026-02 Environmental Credits and Environmental Credit Obligations (Topic 818). ASU 2026-02 provides specific guidance for accounting for environmental credits and environmental credit obligations. For calendar year-end entities, the update will be effective for annual periods beginning on January 1, 2028. Early adoption is permitted. PGE is assessing the impact of adoption on the consolidated financial statements and does not plan to early adopt the standard. Pending Acquisition On February 15, 2026, PGE, through a newly formed, wholly owned subsidiary, entered into an Asset Purchase and Service Area Transfer Agreement (the “Agreement”) with PacifiCorp, an indirect subsidiary of Berkshire Hathaway Energy Company, to acquire select portions of PacifiCorp’s Washington state regulated utility retail business. Under the Agreement, PGE would acquire certain assets and liabilities related to generation, transmission, and distribution business to serve the related service area comprised of approximately 140,000 customers. The stated purchase price is $1.9 billion in cash, subject to customary adjustments, including adjustments for net working capital, regulatory assets and liabilities, assumed liabilities, and capital expenditures at closing. Upon execution of the Agreement, the acquisition was supported by a fully committed bridge facility with Barclays Bank PLC and JPMorgan Chase Bank, N.A. for $1.9 billion. On March 23, 2026, the bridge facility was amended to an amount of approximately $1.3 billion and at the same time, the Company entered into a 364-day Delay Draw Term Loan in the amount of approximately $700 million. Borrowings under the Delayed Draw Term Loan bear interest at a rate equal to either (i) Term SOFR Rate, or (ii) the Alternate Base Rate in each case, plus an applicable margin determined by reference to the Company’s long-term debt securities credit ratings. The Company expects to permanently finance the transaction through a balanced mix of debt, equity, and its minority investment partner, Manulife Infrastructure Fund III L.P. and its affiliates including John Hancock Life Insurance Company (USA) (“Manulife”). In connection with the financing plan, PGE expects equity commitments from Manulife to finance up to $600 million of the purchase. Assuming the closing of the transactions contemplated by the Agreement and the consummation of the financing transactions, Manulife will be the Company's joint venture partner in the business. PGE would remain majority owner and sole operator. The Agreement also provides for certain termination rights, and under certain specified circumstances, the Company may be required to pay PacifiCorp a termination fee of $35 million. The transaction is expected to consummate approximately twelve months after submission of regulatory filings, subject to customary closing conditions and regulatory approvals, including under the Hart-Scott-Rodino Act, Section 203 of the Federal Power Act from the FERC, the Washington Utilities and Transportation Commission (“WUTC”), the OPUC, the Idaho Public Utilities Commission, the Public Service Commission of Utah, the Public Utilities Commission of the State of California, the Public Service Commission of Wyoming, and certain other federal and state regulatory approvals. PGE submitted regulatory applications related to the Acquisition with the WUTC and the OPUC on March 30, 2026 and April 2, 2026, respectively. On July 15, 2026, the Company, jointly with other parties, submitted an application to the FERC seeking approval of the transaction, requesting a decision by December 15, 2026. The transaction is expected to be accounted for as a business combination pursuant to ASC 805, Business Combinations, using the acquisition method of accounting and in which PGE would record the fair value of the assets acquired and liabilities assumed as of the acquisition date. To the extent that the consideration transferred is greater than the fair value of the net assets acquired, goodwill will be recorded.
