* Federal tax credits primarily consist of production tax credits (PTCs) earned from Company-owned wind-powered generating facilities as well as amortization of investment tax credits (ITCs). PTCs are earned based on a per-kilowatt hour rate and, as a result, the annual amount of PTCs earned will vary based on weather conditions and availability of the facilities. PTCs are earned for 10 years from the in-service dates of the corresponding facilities. PGE’s PTC generation will end at various dates through 2033. The generation of production tax credits from Tucannon River Wind Farm ended in 2024. ITCs are deferred and amortized as a reduction of income tax expense over the estimated useful lives of the related properties.
