Retirement Benefits [Abstract] |
Components Of Net Periodic Benefit Cost | The following table provides the components of net periodic benefit costs (credits) relating to all qualified and nonqualified pension and OPEB plans on an aggregate basis for PSEG, excluding Servco. Net periodic pension benefit costs are reduced in 2023 as a result of an accounting order from the BPU authorizing PSE&G to modify its method for calculating the amortization of the net actuarial gain or loss component of pension expense for rate making purposes. See Note 5. Rate Filings. Amounts shown do not reflect the impacts of capitalization, co-owner allocations and the 2023 BPU accounting order. Only the service cost component is eligible for capitalization, when applicable.
