Nine Mile Hydroelectric Power Plant | Washington, USA

Nine Mile is a hydroelectric power plant located in Washington, United States, with an operational capacity of 37.6 MW. Owned and operated by Avista Corp, the facility is currently operational and contributes to the region's renewable energy portfolio. The plant utilizes hydropower as its primary fuel source, a clean and renewable energy technology. In the United States, hydroelectric facilities like Nine Mile are subject to federal regulations under the Federal Energy Regulatory Commission (FERC) and environmental oversight from the EPA, including the Clean Water Act. The plant's capacity places it in the small-to-medium scale range for hydroelectric power generation. As a renewable energy source, Nine Mile helps reduce greenhouse gas emissions compared to fossil fuel-based generation. Its location in Washington, a state with abundant water resources, supports reliable hydropower generation. The facility plays a role in the local grid, providing clean electricity to the surrounding community.

The plant's hydroelectric generation produces no direct CO2, SOx, or NOx emissions, offering environmental benefits over fossil fuel plants. However, hydropower can affect local aquatic ecosystems through changes in water flow and fish passage. The facility's relatively small capacity (37.6 MW) limits its overall environmental footprint, and it operates under U.S. regulations that require environmental impact assessments and mitigation measures.
