Filings with Idaho state regulators indicate Idaho Power wants to close the 522-MW North Valmy coal-fired power station by 2025, or 10 years sooner than expected.
The utility said it will work with NV Energy, co-owner of the plant in Nevada 250 miles east of Reno, on an agreement, the Associated Press reported. NV Energy officials had no comment.
Earlier this year, the Nevada Public Utilities Commission ordered NV Energy to undertake a new economic analysis of the plant’s efficiency due to testimony from the Sierra Club indicated the current closure plan would cost Nevada ratepayers $30 million or more.
Valmy became the last coal-fired utility-owned plant still operating in Nevada after the closure of the Reid-Gardner Generation Station.
Under existing plans, one of Valmy’s units would close in 2031 and the other in 2035. The accelerated plans proposed by Idaho power would close one unit by the end of 2019 and the other in 2025.
