Overview
Greers Ferry Lake is a 96 MW hydroelectric power plant in the United States, operated by the USCE-Little Rock District. It provides renewable energy to the regional grid.
Greers Ferry Lake is a hydroelectric power plant located in the United States, with a generating capacity of 96 megawatts (MW). The facility is owned and operated by the USCE-Little Rock District and is currently in operational status. As a hydroelectric plant, it harnesses the energy of flowing water to generate electricity, contributing to the nation's renewable energy portfolio. The plant operates under the regulatory framework of the United States, which includes federal oversight by agencies such as the Federal Energy Regulatory Commission (FERC) for hydroelectric projects. Hydroelectric power is a well-established technology in the U.S., with many facilities built in the mid-20th century. Greers Ferry Lake, with its 96 MW capacity, falls into the medium-scale range for hydroelectric plants, which can vary from small run-of-river projects to large dams exceeding 1,000 MW. Environmentally, hydroelectric power offers low greenhouse gas emissions compared to fossil fuel plants, but it can affect local aquatic ecosystems and water flow regimes. The facility's location in Arkansas contributes to the regional energy mix, providing a stable source of renewable power. Its operational role supports grid reliability and helps meet state renewable energy goals.
Environmental context
Hydroelectric power generation at Greers Ferry Lake involves minimal direct air emissions, but the reservoir can alter local hydrology and aquatic habitats. The facility's 96 MW capacity indicates a moderate scale, with potential impacts on fish migration and sediment transport. Proximity to populated areas may influence recreational use and water quality management. Overall, the plant's environmental footprint is lower than fossil fuel alternatives, though site-specific factors like reservoir size and operational regime are important.
Frequently asked questions
Greers Ferry Lake is located in the United States, specifically in Arkansas, with coordinates 35.5207 N, -91.9953 W.
The Greers Ferry Lake hydroelectric plant has a generating capacity of 96 megawatts (MW).
The plant is owned and operated by the USCE-Little Rock District, a division of the U.S. Army Corps of Engineers.
Hydroelectric plants in the US are regulated by the Federal Energy Regulatory Commission (FERC) under the Federal Power Act, which governs licensing, safety, and environmental compliance.
Hydroelectric power produces low greenhouse gas emissions but can impact aquatic ecosystems through altered water flow, fish migration barriers, and reservoir sedimentation. Proper management and mitigation measures are required.
