At December 31, 2019, Idaho Power's construction work in progress balance of $552.5 million included relicensing costs of $326.0 million for the HCC, Idaho Power's largest hydropower complex. In 2019, 2018, and 2017, Idaho Power had IPUC authorization to include in its Idaho jurisdiction rates $6.5 million annually ($8.8 million when grossed-up for the effect of income taxes in 2019 and 2018 and $10.7 million when grossed-up for the effect of income taxes in 2017 prior to income tax reform described in Note 2 - "Income Taxes") of AFUDC relating to the HCC relicensing project. Collecting these amounts will reduce the amount collected in the future once the HCC relicensing costs are approved for recovery in base rates. At December 31, 2019, Idaho Power's regulatory liability for collection of AFUDC relating to the HCC was $151.7 million.

Idaho Power's ownership interest in three jointly-owned generating facilities is included in the table above. Under the joint operating agreements for these facilities, each participating utility is responsible for financing its share of construction, operating, and leasing costs. Idaho Power's proportionate share of operating expenses for each facility is included in the Consolidated Statements of Income. These jointly-owned facilities, including balance sheet amounts and the extent of Idaho Power’s participation, were as follows at December 31, 2019 (in thousands of dollars):
