Milner Hydro Hydroelectric Power Plant, Idaho | United States

Milner Hydro is a hydroelectric power plant located in Idaho, United States, with a generating capacity of 59.5 megawatts. Owned and operated by Idaho Power Co, the facility is currently operational and contributes to the regional power grid. As a hydroelectric plant, it utilizes the flow of water to produce electricity, a renewable energy source that supports clean energy goals. The plant operates under the regulatory framework of the United States, including the Clean Air Act and state-level environmental regulations. Hydroelectric plants like Milner Hydro are subject to Federal Energy Regulatory Commission (FERC) licensing and oversight, ensuring compliance with environmental and operational standards. The technology involves turbines driven by water flow, typically from a dam or diversion structure, and the 59.5 MW capacity places it in the small-to-medium scale for hydroelectric facilities in the US. Milner Hydro plays a role in Idaho's energy mix, providing low-carbon electricity to the grid. Its operation supports Idaho Power's portfolio of renewable energy resources, contributing to the company's commitment to clean energy. The plant's location in the Snake River basin leverages the region's water resources for power generation, aligning with the state's emphasis on hydropower as a key energy source.

As a hydroelectric plant, Milner Hydro generates electricity with minimal direct air emissions, avoiding CO2, SOx, and NOx associated with fossil fuels. However, hydropower can affect aquatic ecosystems and water flow regimes. The plant's location in Idaho, a region with significant hydropower infrastructure, means it operates within a regulatory framework that includes FERC licensing conditions to mitigate environmental impacts, such as fish passage and water quality monitoring. The 59.5 MW capacity represents a moderate scale, with environmental effects typically proportional to the size and design of the facility.
