Ice Harbor Hydroelectric Power Plant | Washington State Renewable Energy Facility

Ice Harbor is a hydroelectric power plant located in Washington State, United States, with a generating capacity of 603 megawatts. Operated by the USACE Northwestern Division, the facility plays a key role in the region's renewable energy portfolio. Hydroelectric plants like Ice Harbor convert the kinetic energy of flowing water into electricity, providing a low-carbon power source. The plant operates under the regulatory framework of the Federal Energy Regulatory Commission (FERC) and must comply with environmental standards set by the Clean Water Act and the National Environmental Policy Act (NEPA). As a hydroelectric facility, it does not emit CO2, SOx, or NOx during operation, distinguishing it from fossil fuel plants. The 603 MW capacity places it in the large-scale category for hydropower in the United States. Ice Harbor contributes to grid stability and supports the Pacific Northwest's energy needs, particularly during peak demand periods. Its operation as a run-of-river or storage facility depends on water flow management, which also provides benefits such as flood control and irrigation support. The plant's long operational history underscores its importance to the local energy infrastructure.

As a hydroelectric plant, Ice Harbor has a low carbon footprint but can affect local aquatic ecosystems through changes in water flow and fish passage. The facility is located on the Snake River, a major tributary of the Columbia River, which supports salmon and steelhead populations. Mitigation measures such as fish ladders are typically employed to reduce ecological impact. The plant's operation aligns with regional renewable energy goals, though it must balance power generation with environmental stewardship.
