Overview
John Day is a 2,160 MW hydroelectric power plant operated by USACE Northwestern Division in the United States. It is a major renewable energy facility on the Columbia River.
John Day is a large hydroelectric power plant located in the United States, specifically on the Columbia River. With a capacity of 2,160 MW, it ranks among the largest hydroelectric facilities in the country. The plant is owned and operated by the USACE Northwestern Division and is currently operational, contributing significantly to the regional power grid. The facility operates using hydroelectric technology, which harnesses the kinetic energy of flowing water to generate electricity. As a renewable energy source, hydroelectric power has a low carbon footprint compared to fossil fuel-based plants. The John Day plant benefits from the consistent water flow of the Columbia River, which supports reliable power generation. The plant's capacity places it in the large-scale category for hydroelectric facilities globally. Environmentally, hydroelectric plants like John Day produce no direct emissions during operation, but they can impact local aquatic ecosystems and fish migration patterns. The plant's location on the Columbia River, a major waterway in the Pacific Northwest, means it operates under strict environmental regulations, including those related to fish passage and water quality. The facility plays a key role in providing clean energy to the region, supporting both residential and industrial needs.
Environmental context
Hydroelectric power generation has a low carbon footprint but can affect local aquatic ecosystems. The John Day plant is located on the Columbia River, which supports salmon runs and other wildlife. Operations must comply with environmental regulations to mitigate impacts on fish migration and water quality. The facility's large capacity means it has a significant role in regional renewable energy production.
Frequently asked questions
The John Day hydroelectric plant is located on the Columbia River in the United States, with coordinates approximately 45.7164 N, -120.6941 W.
The John Day hydroelectric plant has a capacity of 2,160 megawatts (MW), making it one of the largest hydroelectric facilities in the United States.
