Bonneville Hydroelectric Power Plant | 1,162 MW Renewable Energy Facility in Oregon

Bonneville is a hydroelectric power plant located on the Columbia River in Oregon, United States. With a capacity of 1,162 MW, it is one of the larger hydroelectric facilities in the country, contributing significantly to the region's renewable energy portfolio. The plant is operated by the USACE Northwestern Division and has been in operational status. The facility utilizes hydroelectric technology, which generates electricity by harnessing the flow of water. As a renewable energy source, hydroelectric power produces no direct CO2 emissions during operation. The plant's capacity places it in the large-scale category for hydroelectric power generation in the United States. Regulatory oversight for such facilities typically involves Federal Energy Regulatory Commission (FERC) licensing and compliance with environmental laws such as the Clean Water Act and the National Environmental Policy Act (NEPA). Bonneville plays a key role in the Pacific Northwest's power grid, providing reliable baseload electricity and supporting grid stability. Its operation contributes to the region's renewable energy goals and reduces reliance on fossil fuel-based generation. The plant's location on the Columbia River also supports water management and recreational activities in the area.

As a hydroelectric plant, Bonneville has a low carbon footprint compared to fossil fuel plants, but its operation can affect local aquatic ecosystems. The Columbia River supports salmon runs, and the facility includes fish ladders to mitigate impacts on fish migration. The plant's large capacity means it displaces significant greenhouse gas emissions that would otherwise come from thermal power sources.
