Leases [Abstract] |
Leases | Note 13.Leases Leases as Lessee SCE enters into various agreements to purchase power, electric capacity and other energy products that may be accounted for as leases when SCE has dispatch rights that determine when and how a plant runs. SCE also leases property and equipment primarily related to vehicles, office space and other equipment. The terms of the lease contracts included in the table below are primarily 2 to 20 years for PPA leases, 3 to 72 years for office leases, and 5 to 13 years for the remaining other operating leases. The following table summarizes SCE's lease payments for operating and finance leases as of December 31, 2021:
