Leases [Abstract] |
Early Termination [Policy Text Block] | The option to extend or terminate a lease is based on customary early termination provisions in the contract, such as payment defaults, bankruptcy, and lack of performance on energy delivery.
Separation of Lease and Nonlease Components [Policy Text Block] | Capacity payments are generally considered lease elements as they cover the majority of available output from a facility. The allocation of contract payments between the lease and non-lease elements is made at the inception of the lease.
Incremental Borrowing Rate [Policy Text Block] | we use the subsidiaries’ incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.
Short-term Leases [Policy Text Block] | eases with an initial term of 12 months or less are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term.
