Site description

Idaho Power Company and NV Energy’s North Valmy Generating Station is in Valmy, Nevada in Humboldt County. North Valmy Station began operations in 1981 and now operates two coal-fired units capable of generating 522-MW. This power plant is Nevada’s last utility-owned, coal-fired power plant in operation. Plans have been put into place to close both of Plant Valmy’s coal-fired units by 2025 and replace them with two new solar-plus-storage projects totaling 600-MW of generating capacity and 480-MW of storage capacity. North Valmy Generating Station’s Landfill is regulated under the CCR rule.
