Organization Consolidation And Presentation Of Financial Statements [Abstract]
General	1. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary for a fair statement of our consolidated financial position as of June 30, 2021, our consolidated results of operations for the three and six months ended June 30, 2021 and 2020, and cash flows for the six months ended June 30, 2021 and 2020. The consolidated results of operations for the three and six months ended June 30, 2021, are not necessarily indicative of the results to be expected for the entire year. These financial statements should be read in conjunction with the financial statements and notes thereto included in our 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission. The accompanying financial statements reflect the consolidated accounts of Old Dominion Electric Cooperative and TEC. We are a not-for-profit wholesale power supply cooperative, incorporated under the laws of the Commonwealth of Virginia in 1948. We have two classes of members. Our eleven Class A members are customer-owned electric distribution cooperatives engaged in the retail sale of power to member customers located in Virginia, Delaware, and Maryland. Our sole Class B member is TEC, a taxable corporation owned by our member distribution cooperatives. Our board of directors is composed of two representatives from each of the member distribution cooperatives and one representative from TEC. In accordance with Consolidation Accounting, TEC is considered a variable interest entity for which we are the primary beneficiary. We have eliminated all intercompany balances and transactions in consolidation. The assets and liabilities and non-controlling interest of TEC are recorded at carrying value and the consolidated assets were $5.8 million as of June 30, 2021 and December 31, 2020. The income taxes reported on our Condensed Consolidated Statements of Revenues, Expenses, and Patronage Capital relate to the tax provision for TEC. As TEC is wholly-owned by our Class A members, its equity is presented as a non-controlling interest in our consolidated financial statements. Our rates are set periodically by a formula that was accepted for filing by FERC and are not regulated by the public service commissions of the states in which our member distribution cooperatives operate. We comply with the Uniform System of Accounts as prescribed by FERC. In conformity with GAAP, the accounting policies and practices applied by us in the determination of rates are also employed for financial reporting purposes. The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported therein. Actual results could differ from those estimates. We did not have any other comprehensive income for the periods presented. The impact that the COVID-19 pandemic will have on our consolidated results of operations, financial condition, and cash flows is uncertain. We continue to actively manage our business to respond to this health crisis and will continue to evaluate the nature and extent of any impact.

Fair Value Measurements

Fair Value Measurements	6 Months Ended
	Jun. 30, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	2. The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability. The following table summarizes our financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2021 and December 31, 2020: Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable June 30, Assets Inputs Inputs 2021 (Level 1) (Level 2) (Level 3) (in thousands) Nuclear decommissioning trust (1) $ 74,570 $ 74,570 $ — $ — Nuclear decommissioning trust - net asset value (1)(2) 190,015 — — — Unrestricted investments and other (3) 179 — 179 — Derivatives - gas and power (4) 37,003 30,942 3,689 2,372 Total Financial Assets $ 301,767 $ 105,512 $ 3,868 $ 2,372 Derivatives - gas and power (4) $ 2,005 $ — $ 2,005 $ — Total Financial Liabilities $ 2,005 $ — $ 2,005 $ — Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable December Assets Inputs Inputs 2020 (Level 1) (Level 2) (Level 3) (in thousands) Nuclear decommissioning trust (1) $ 76,037 $ 76,037 $ — $ — Nuclear decommissioning trust - net asset value (1)(2) 166,300 — — — Unrestricted investments and other (3) 166 — 166 — Derivatives - gas and power (4) 3,478 1,582 480 1,416 Total Financial Assets $ 245,981 $ 77,619 $ 646 $ 1,416 Derivatives - gas and power (4) $ 6,406 $ — $ 6,406 $ — Total Financial Liabilities $ 6,406 $ — $ 6,406 $ — (1) For additional information about our nuclear decommissioning trust, see Note 4—Investments below. (2) Nuclear decommissioning trust includes investments measured at net asset value per share (or its equivalent) as a practical expedient and these investments have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in our Condensed Consolidated Balance Sheet. (3) Unrestricted investments and other includes investments that are related to equity securities. (4) Derivatives - gas and power represent natural gas futures contracts and call option premiums (Level 1 and Level 2), and financial transmission rights (Level 3). Level 1 are indexed against NYMEX. Level 2 are valued by ACES using observable market inputs for similar transactions. Level 3 are valued by ACES using unobservable market inputs, including situations where there is little market activity. Sensitivity in the market price of financial transmission rights could impact the fair value. For additional information about our derivative financial instruments, see Note 1 of the Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives And Hedging	3. We are exposed to market price risk by purchasing power to supply the power requirements of our member distribution cooperatives that are not met by our owned generation. In addition, the purchase of fuel to operate our generating facilities also exposes us to market price risk. To manage this exposure, we utilize derivative instruments. See Note 1 of the Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K. Changes in the fair value of our derivative instruments accounted for at fair value are recorded as a regulatory asset or regulatory liability. The change in these accounts is included in the operating activities section of our Condensed Consolidated Statements of Cash Flows. Outstanding derivative instruments, excluding contracts accounted for as normal purchase/normal sale, were as follows: Quantity As of June 30, As of December 31, Commodity Unit of Measure 2021 2020 Natural gas MMBTU 61,310,000 55,630,000 Purchased power - financial transmission rights MWh 10,665,893 6,922,373 The fair value of our derivative instruments, excluding contracts accounted for as normal purchase/normal sale, was as follows: Fair Value As of June 30, As of December 31, Balance Sheet Location 2021 2020 (in thousands) Derivatives in an asset position: Natural gas futures contracts Other assets $ 34,631 $ 2,062 Financial transmission rights Other assets 2,372 1,416 Total derivatives in an asset position $ 37,003 $ 3,478 Derivatives in a liability position: Natural gas futures contracts Other liabilities $ 2,005 $ 6,406 Total derivatives in a liability position $ 2,005 $ 6,406 The Effect of Derivative Instruments on the Condensed Consolidated Statements of Revenues, Expenses, and Patronage Capital for the Three and Six Months Ended June 30, 2021 and 2020 Amount of Gain Location of Amount of Gain (Loss) Reclassified (Loss) Recognized Gain (Loss) from Regulatory Asset/Liability in Regulatory Reclassified into Income for the Derivatives Asset/Liability for from Regulatory Three Months Six Months Accounted Derivatives as of Asset/Liability Ended Ended Regulatory Accounting June 30, into Income June 30, June 30, 2021 2020 2021 2020 2021 2020 (in thousands) (in thousands) Natural $ 37,203 $ (12,638 ) Fuel $ 1,333 $ (5,726 ) $ (3,033 ) $ (27,192 ) Purchased power 2,372 68 Purchased power 839 (898 ) 4,451 (4,482 ) Total $ 39,575 $ (12,570 ) $ 2,172 $ (6,624 ) $ 1,418 $ (31,674 ) Our hedging activities expose us to credit-related risks. We use hedging instruments, including forwards, futures, financial transmission rights, and options, to mitigate our power market price risks. Because we rely substantially on the use of hedging instruments, we are exposed to the risk that counterparties will default in performance of their obligations to us. Although we assess the creditworthiness of counterparties and other credit issues related to these hedging instruments, and we may require our counterparties to post collateral with us, defaults may still occur. Defaults may take the form of failure to physically deliver purchased energy or failure to pay. If a default occurs, we may be forced to enter into alternative contractual arrangements or purchase energy in the forward, short-term, or spot markets at then-current market prices that may exceed the prices previously agreed upon with the defaulting counterparty.

Other	5. Revolving Credit Facility We maintain a revolving credit facility to cover our short-term and medium-term funding needs that are not met by cash from operations or other available funds. Commitments under this syndicated credit agreement extend until February 28, 2025. Available funding under this facility totals $500 million through March 3, 2022, and $400 million from March 4, 2022 through February 28, 2025. As of June 30, 2021 and December 31, 2020, we had no borrowings and had a $0.5 million letter of credit outstanding under this facility. Cash and Cash Equivalents For purposes of our Condensed Consolidated Statements of Cash Flows, we consider all unrestricted highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. The following table provides a reconciliation of cash and cash equivalents and restricted cash and cash equivalents reported within our Condensed Consolidated Balance Sheets that sum to the total of the same amounts shown in our Condensed Consolidated Statements of Cash Flows: As of June 30, 2021 2020 (in thousands) Cash and cash equivalents $ 58,599 $ 42,914 Restricted cash and cash equivalents — 24,349 Total $ 58,599 $ 67,263 Restricted cash and cash equivalents related to funds held in escrow for payments related to the construction of Wildcat Point and in July 2020 the funds were released and paid to the contractors. Revenue Recognition Our operating revenues are derived from sales of power and renewable energy credits to our member distribution cooperatives and non-members. We supply power requirements (energy and demand) to our eleven member distribution cooperatives subject to substantially identical wholesale power contracts with each of them. We bill our member distribution cooperatives monthly and each member distribution cooperative is required to pay us monthly for power furnished under its wholesale power contract. We transfer control of the electricity over time and our member distribution cooperatives simultaneously receive and consume the benefits of the electricity. The amount we invoice our member distribution cooperatives on a monthly basis corresponds directly to the value to the member distribution cooperatives of our performance, which is determined by our formula rate included in the wholesale power contract. We sell excess energy and renewable energy credits to non-members at prevailing market prices as control is transferred. We sell excess purchased and generated energy to PJM, TEC, or third parties. Sales to TEC consist of sales of excess energy that we do not need to meet the actual needs of our member distribution cooperatives. TEC’s sales to third parties are reflected as non-member revenues. For the three and six months ended June 30, 2021 and 2020, we had no sales to TEC and TEC had no sales to third parties. Our operating revenues for the three and six months ended June 30, 2021 and 2020, were as follows: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (in thousands) Revenues from sales to: Member distribution cooperatives Energy revenues $ 70,220 $ 80,372 $ 161,054 $ 179,293 Renewable energy credits 8 13 17 13 Demand revenues 102,477 103,491 196,377 208,735 Total revenues from sales to member distribution cooperatives 172,705 183,876 357,448 388,041 Non-members: Energy revenues 6,398 5,665 12,589 10,142 Renewable energy credits 2,381 — 2,564 104 Demand revenues — 21 — 21 Total revenues from sales to non-members 8,779 5,686 15,153 10,267 Total operating revenues $ 181,484 $ 189,562 $ 372,601 $ 398,308

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements	6. 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. The guidance provides temporary optional expedients and exceptions related to contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate and other interbank offered rates to alternative reference rates. The new guidance allows entities to elect not to apply certain modification accounting requirements, if certain criteria are met, to contracts affected by what the guidance calls reference rate reform. An entity that makes this election would consider changes in reference rates and other contract modifications related to reference rate reform to be events that do not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The ASU notes that changes in contract terms that are made to effect the reference rate reform transition are considered related to the replacement of a reference rate if they are not the result of a business decision that is separate from or in addition to changes to the terms of a contract to effect that transition. The guidance is effective upon issuance and generally can be applied as of March 12, 2020 through December 31, 2022. We are continuing to evaluate the impact of this standard on our financial statements.

[1]	For additional information about our nuclear decommissioning trust, see Note 4—Investments below.
[2]	Nuclear decommissioning trust includes investments measured at net asset value per share (or its equivalent) as a practical expedient and these investments have not been categorized in the fair value hierarchy.  The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in our Condensed Consolidated Balance Sheet.
[3]	Unrestricted investments and other includes investments that are related to equity securities.
[4]	Derivatives - gas and power represent natural gas futures contracts and call option premiums (Level 1 and Level 2), and financial transmission rights (Level 3).  Level 1 are indexed against NYMEX.  Level 2 are valued by ACES using observable market inputs for similar transactions.  Level 3 are valued by ACES using unobservable market inputs, including situations where there is little market activity.  Sensitivity in the market price of financial transmission rights could impact the fair value.  For additional information about our derivative financial instruments, see Note 1 of the Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K.
