Variable Interest Entity [Line Items]
Variable Interest Entities (VIEs) [Text Block]	Variable Interest Entities (VIEs) VIE for which PSEG LI is the Primary Beneficiary PSEG LI consolidates Servco, a marginally capitalized VIE, which was created for the purpose of operating LIPA’s T&D system in Long Island, New York as well as providing administrative support functions to LIPA. PSEG LI is the primary beneficiary of Servco because it directs the operations of Servco, the activity that most significantly impacts Servco’s economic performance and it has the obligation to absorb losses of Servco that could potentially be significant to Servco. Such losses would be immaterial to PSEG. Pursuant to the OSA, Servco’s operating costs are paid entirely by LIPA, and therefore, PSEG LI’s risk is limited related to the activities of Servco. PSEG LI has no current obligation to provide direct financial support to Servco. In addition to payment of Servco’s operating costs as provided for in the OSA, PSEG LI receives an annual contract management fee. PSEG LI’s annual contractual management fee, in certain situations, could be partially offset by Servco’s annual storm costs not approved by the Federal Emergency Management Agency, limited contingent liabilities and penalties for failing to meet certain performance metrics. For transactions in which Servco acts as principal and controls the services provided to LIPA, such as transactions with its employees for labor and labor-related activities, including pension and OPEB-related transactions, Servco records revenues and the related pass-through expenditures separately in Operating Revenues and O&M Expense, respectively. In 2022, 2021 and 2020, Servco recorded $516 million, $511 million and $520 million, respectively, of O&M costs, the full reimbursement of which was reflected in Operating Revenues. For transactions in which Servco acts as an agent for LIPA, it records revenues and the related expenses on a net basis, resulting in no impact on PSEG’s Consolidated Statement of Operations. VIE for which PSEG is not the Primary Beneficiary PSEG holds a 25% equity interest in Ocean Wind JV HoldCo, LLC (OWH), which holds Ørsted North America Inc.’s (Ørsted) Ocean Wind 1 project that is expected to achieve full commercial operation in 2025. OWH is considered a VIE since its equity investments at risk are not sufficient to permit this entity to finance its activities without additional subordinated financial support. Since PSEG does not have voting control or the power to direct the activities of OWH that most significantly impact its economic performance, PSEG has determined that it is not the primary beneficiary and therefore accounts for this investment under the equity method. As of December 31, 2022 and 2021, PSEG’s carrying amount of its investment in OWH was $225 million and $111 million, respectively, which is included in Long-Term Investments on PSEG’s Consolidated Balance Sheet. PSEG’s maximum exposure to loss is limited to the carrying amount of its investment. In January 2023, PSEG agreed to sell to Ørsted its 25% equity interest in OWH. The sale proceeds approximate PSEG’s carrying value of the investment and no material gain or loss is expected upon disposition nor is the sale contingent upon Ørsted electing to proceed to the construction phase of the project. The sale is contingent upon finalization of a purchase and sale agreement with Ørsted as well as other closing conditions and any potential state regulatory approval that may be required to close on the transaction. The sale is expected to close in the first half of 2023. PSEG has no further obligation to make any capital contributions to the project prior to closing on the transaction.
