Overview
Big Cliff is an 18 MW hydroelectric power plant in Oregon, United States, operated by the USACE Northwestern Division. It generates renewable electricity from hydropower.
Big Cliff is a hydroelectric power plant located in Oregon, United States, with an installed capacity of 18 megawatts (MW). It is owned and operated by the USACE Northwestern Division and is currently operational. As a hydroelectric facility, it contributes to the region's renewable energy portfolio. The plant operates under the regulatory framework of the United States, including the Clean Water Act and Federal Energy Regulatory Commission (FERC) oversight for hydropower projects. Hydroelectric plants like Big Cliff typically use run-of-river or reservoir-based systems to generate electricity, with minimal direct emissions compared to fossil fuel plants. Big Cliff plays a role in the local power grid by providing clean, renewable energy. Its location in the Pacific Northwest, a region rich in hydropower resources, supports the area's energy needs while reducing reliance on fossil fuels. The facility's operational status ensures continued contribution to the regional energy mix.
Environmental context
As a hydroelectric plant, Big Cliff produces electricity with negligible direct CO2, SOx, and NOx emissions, offering environmental benefits over fossil fuel generation. However, hydropower can affect local aquatic ecosystems and water flow regimes. The plant's capacity of 18 MW is relatively small, which may limit its ecological footprint. Its location in Oregon, a state with strong environmental regulations, ensures compliance with water quality and habitat protection standards.
Frequently asked questions
Big Cliff is located in Oregon, United States, at coordinates 44.7514, -122.2832.
Big Cliff has an installed capacity of 18 megawatts (MW), making it a small-scale hydroelectric facility.
Big Cliff is owned and operated by the USACE Northwestern Division, a branch of the U.S. Army Corps of Engineers.
Hydroelectric plants in the U.S. must comply with the Clean Water Act, the National Environmental Policy Act (NEPA), and FERC licensing requirements, which include environmental impact assessments and fish passage measures.
Hydroelectric power produces low direct emissions but can alter aquatic habitats, affect fish migration, and change water flow patterns. Modern projects often include mitigation measures like fish ladders and minimum flow releases.
