Idaho Power Seeks to Close Coal Plant a Decade Early

By Editors of Power Engineering

According to filings to the Idaho Public Utilities Commission, Idaho Power seeks to close the coal-fired North Valmy Power Plant much earlier than expected.

The utility now wants to close both units at the 522-MW plant by 2025. Previously, they were expecting to close Unit 1 by 2031 and Unit 2 by 2035.

Idaho Power told the commission they anticipate it wouldn’t be economically viable or reliable to operate the facility beyond 2025, especially with the commitment to move away from coal.

The plant is jointly-owned by NV Energy and Idaho Power. Unit 1 went into service in 1981 and Unit 2 followed in 1985.

The same filing also proposed to increase fees to customers by $35.2 million beginning June 1 of next year, or $3.08 monthly per customer, due to the change in depreciation rates.
