Condensed Financial Statements, Captions [Line Items] |
Principles of Consolidation | Principles of Consolidation IDACORP’s and Idaho Power’s consolidated financial statements include the assets, liabilities, revenues, and expenses of each company and its wholly-owned subsidiaries listed above, as well as any variable interest entity (VIE) for which the respective company is the primary beneficiary. Investments in VIEs for which the companies are not the primary beneficiaries, but have the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method of accounting. IDACORP also consolidates one VIE, Marysville Hydro Partners (Marysville), which is a joint venture owned 50 percent by Ida-West and 50 percent by Environmental Energy Company (EEC). At December 31, 2023 and 2022, Marysville had approximately $14.9 million of primarily hydropower plant assets. EEC has borrowed amounts from Ida-West to fund a portion of its required capital contributions to Marysville. The loans are payable from EEC’s share of distributions from Marysville and are secured by the stock of EEC and EEC’s interest in Marysville. Ida-West is identified as the primary beneficiary because the combination of its ownership interest in the joint venture with the intercompany note and the EEC note result in Ida-West's ability to control the activities of the joint venture. The BCC investment is also a VIE, but because the power to direct the activities that most significantly impact the economic performance of BCC is shared with the joint-owner, Idaho Power is not the primary beneficiary. The carrying value of Idaho Power's investment in BCC was $24.1 million at December 31, 2023, and Idaho Power's maximum exposure to loss is the carrying value, any additional future contributions to BCC, and a $47.6 million guarantee for mine reclamation costs. BCC has a reclamation trust fund set aside specifically for the purpose of paying the reclamation costs, the market value of which exceeded the total estimated reclamation obligation at December 31, 2023. The guarantee, reclamation obligation, and reclamation trust are discussed further in Note 9 - "Commitments." IFS's affordable housing limited partnership and other real estate tax credit investments are also VIEs for which IDACORP is not the primary beneficiary. IFS's limited partnership interests range from 4 to 100 percent and were acquired between 2003 and 2023. As a limited partner, IFS does not control these entities and they are not consolidated. IFS’s maximum exposure to loss in these developments is limited to its net carrying value, which was $57.3 million at December 31, 2023. Ida-West's other investments in PURPA facilities, Idaho Power's investment in BCC, and IFS's investments are accounted for under the equity method of accounting (see Note 14 - "Investments"). Except for amounts related to sales of electricity by Ida-West's PURPA projects to Idaho Power, all intercompany transactions and balances have been eliminated in consolidation. The accompanying consolidated financial statements include Idaho Power's proportionate share of utility plant and related operations resulting from its interests in jointly-owned plants (see Note 12 - "Property, Plant and Equipment and Jointly-Owned Projects").
