Overview
Lewis Smith Dam is a 181 MW hydroelectric power plant in Alabama, United States, operated by Alabama Power Co. It generates renewable electricity from hydropower.
Lewis Smith Dam is a hydroelectric power plant located in Alabama, United States, with a generating capacity of 181 megawatts (MW). The facility is owned by Alabama Power Co and is currently operational, contributing to the region's renewable energy portfolio. As a hydroelectric facility, Lewis Smith Dam utilizes the flow of water to generate electricity, a technology that produces no direct CO2, SOx, or NOx emissions. The plant operates under the regulatory framework of the US Clean Air Act, though hydroelectric plants are generally subject to less stringent air quality regulations compared to fossil fuel plants. The dam's capacity places it in the medium-to-large scale for hydropower in the US. The plant plays a role in Alabama's energy mix by providing clean, renewable power to the grid. Its operation supports local energy reliability and reduces reliance on fossil fuels. The facility's location on a river also involves considerations for aquatic ecosystems and water management, which are typical for hydroelectric projects.
Environmental context
Hydroelectric power generation at Lewis Smith Dam involves minimal air emissions, but the facility's reservoir can affect local aquatic habitats and water flow regimes. The dam's operation is subject to Federal Energy Regulatory Commission (FERC) licensing requirements, which include environmental mitigation measures. The surrounding area in Alabama features diverse ecosystems, and the plant's management of water levels can influence downstream water quality and fish populations.
Frequently asked questions
Lewis Smith Dam is located in Alabama, United States, at coordinates 33.9406, -87.1077.
Lewis Smith Dam has a generating capacity of 181 megawatts (MW), making it a medium-to-large hydroelectric facility.
Lewis Smith Dam is owned by Alabama Power Co, a major utility in the region.
Hydroelectric plants in the US are regulated under the Federal Power Act by the Federal Energy Regulatory Commission (FERC), which oversees licensing and environmental compliance. The Clean Water Act also applies to water quality and discharge.
Hydroelectric power produces no direct air emissions, but dams can alter river ecosystems, affect fish migration, and change water temperature and flow. Mitigation measures like fish ladders and minimum flow requirements are often implemented.
