Leases [Abstract] |
Leases | (19) Leases In 2021, Houston Electric entered into a temporary short-term lease and long-term leases for temporary generation. The short-term lease agreement expired on December 31, 2022. Effective January 1, 2023, all temporary generation assets were leased under the long-term lease agreement. Expenses associated with the short-term lease, including carrying costs, are deferred to a regulatory asset and totaled $89 million and $100 million as of December 31, 2024 and 2023, respectively. The long-term lease agreement includes up to 505 MW of TEEEF, all of which was delivered as of December 31, 2022, triggering lease commencement at delivery, with an initial term ending in 2029 for all TEEEF leases. The total cash payments under the long-term lease totaled $664 million, with the final $485 million paid in 2022. Houston Electric derecognized the finance lease liability when the extinguishment criteria in Topic 405 - Liabilities was achieved. Per the terms of the agreement, lease payments are due and made in full by Houston Electric upon taking possession of the asset, relieving substantially all of the associated finance lease liability at that time. The remaining finance lease liability associated with the commenced long-term TEEEF agreement was not significant as of December 31, 2024 and 2023 and relates to removal costs that will be incurred at the end of the lease term. As of December 31, 2024, Houston Electric had secured a first lien on the assets leased under the prepayment agreement, except for assets with lease payments totaling $79 million, which is being held in an escrow account, not controlled by Houston Electric, and the funds will be released when a first lien can be secured by Houston Electric. Expenses associated with the long-term lease, including variable costs associated with the operation and maintenance of the temporary generation assets, depreciation expense on the right of use asset and carrying costs, are deferred to a regulatory asset as a recoverable cost under the 2021 Texas legislation and totaled $158 million and $124 million as of December 31, 2024 and 2023, respectively. For further discussion of the regulatory impacts, see Note 7. The components of lease cost, included in Operation and maintenance expense on the Registrants’ respective Statements of Consolidated Income, are as follows for the periods presented:
