Related Party Transactions [Abstract] |
Related Party Transactions | Related Party Transactions The NYSPSC generally requires that the Utilities and Con Edison’s other subsidiaries be operated as separate entities. The Utilities and the other subsidiaries are required to have separate operating employees and operating officers of the Utilities may not be operating officers of the other subsidiaries. The Utilities may provide administrative and other services to, and receive such services from, Con Edison and its other subsidiaries only pursuant to cost allocation procedures approved by the NYSPSC. Transfers of assets between the Utilities and Con Edison or its other subsidiaries may be made only as approved by the NYSPSC. The debt of the Utilities is to be raised directly by the Utilities and not derived from Con Edison. Without the prior permission of the NYSPSC, the Utilities may not make loans to, guarantee the obligations of, or pledge assets as security for the indebtedness of Con Edison or its other subsidiaries. The NYSPSC limits the dividends that the Utilities may pay Con Edison. See “Dividends” in Note C. As a result, substantially all of the net assets of CECONY and O&R ($16,312 million and $888 million, respectively), at December 31, 2021, are considered restricted net assets. The NYSPSC may impose additional measures to separate, or “ring fence,” the Utilities from Con Edison and its other subsidiaries. See “Rate Plans” in Note B. The costs of administrative and other services provided by CECONY to, and received by it from, Con Edison and its other subsidiaries for the years ended December 31, 2021, 2020 and 2019 were as follows:
| CECONY
(Millions of Dollars) | 2021 | 2020 | 2019
Cost of services provided | $137 | $128 | $121
Cost of services received | 68 | 66 | 64
In addition, CECONY and O&R have joint gas supply arrangements in connection with which CECONY sold to O&R $90 million, $59 million and $71 million of natural gas for the years ended December 31, 2021, 2020 and 2019, respectively. These amounts are net of the effect of related hedging transactions. The Utilities perform work and incur expenses on behalf of NY Transco, a company in which CET Electric has a 45.7 percent equity interest. The Utilities bill NY Transco for such work and expenses in accordance with established policies. For the years ended December 31, 2021 and 2020, the amounts billed by the Utilities to NY Transco were $5.9 million and immaterial, respectively. In May 2016, CECONY transferred certain electric transmission projects to NY Transco. CECONY has storage and wheeling service contracts with Stagecoach Gas Services LLC (Stagecoach), a joint venture formerly owned by a subsidiary of CET Gas and a subsidiary of Crestwood Equity Partners LP (Crestwood). In addition, CECONY is the replacement shipper on one of Crestwood’s firm transportation agreements with Tennessee Gas Pipeline Company LLC. CECONY incurred costs for storage and wheeling services from Stagecoach of $31 million, $34 million and $33 million for the years ended December 31, 2021, 2020 and 2019, respectively. During 2021, a subsidiary of CET Gas completed the sale of its 50 percent interest in Stagecoach. See Note W. CECONY has a 20-year transportation contract with Mountain Valley Pipeline, LLC (MVP) for 250,000 dekatherms per day of capacity. CET Gas owns a 10.2 percent equity interest in MVP (that is expected to be reduced to 8.5 percent). See "Investments - 2020 and 2021 Partial Impairments of Investment in Mountain Valley Pipeline, LLC (MVP) " in Note A. In October 2017, the Environmental Defense Fund and the Natural Resource Defense Council requested the NYSPSC to prohibit CECONY from recovering costs under its MVP contract unless CECONY can demonstrate that the contract is in the public interest. CECONY advised the NYSPSC that it would respond to the request if the NYSPSC opened a proceeding to consider this request. For the years ended December 31, 2021 and 2020, CECONY incurred no costs under the contract. FERC has authorized CECONY to lend funds to O&R for a period of not more than 12 months, in an amount not to exceed $250 million, at prevailing market rates. At December 31, 2021 and 2020 there were no outstanding loans to O&R. The Clean Energy Businesses had financial electric capacity contracts with CECONY and O&R during 2021 and 2020. For the years ended December 31, 2021 and 2020, the Clean Energy Businesses realized a $4 million loss and an immaterial loss, respectively, under these contracts.
