Site description

Idaho Power Company’s North Valmy Generating Station is located in Humboldt County, NV. 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 down both of Plant Valmy’s coal-fired units by 2025. The first coal-fired unit is scheduled to be retired at the end of 2019. North Valmy Generating Station’s Landfill is regulated under the CCR-rule. You can find the industry reported data here. For more information on this site see EIP’s 2019 National Coal Ash Report, Coal’s Poisonous Legacy.
