World Power Plants

Taum Sauk, located in the United States at coordinates 37.5208° N, -90.8347° W, stands out as a notable hydroelectric power generation facility with a capacity of 408 MW. Commissioned in 1964 and operated by Union Electric Company (Missouri), this power plant plays a vital role in the local energy landscape by harnessing the power of water to produce electricity. The use of hydroelectric technology not only contributes to the energy supply but also aligns with environmental goals by providing a renewable source of energy that minimizes greenhouse gas emissions. The technology implemented at Taum Sauk involves a pumped storage system, which allows for energy storage and generation by utilizing elevation changes. This innovative method enables the power plant to generate electricity during peak demand periods while storing energy during low demand times, effectively balancing the grid and enhancing overall energy reliability. The operational capabilities of Taum Sauk are essential to meeting the fluctuating energy needs of the region, particularly in a landscape that increasingly incorporates renewable sources like wind and solar. Situated in a region with abundant water resources, Taum Sauk’s significance is amplified as it provides a stable source of electricity to the local grid, supporting both urban and rural areas. The plant’s operations are particularly relevant within the context of Missouri’s energy policies, which emphasize sustainability and the adoption of renewable energy sources. By employing hydroelectric power, Taum Sauk contributes to Missouri’s objectives of reducing carbon footprints and enhancing energy independence. As a long-standing facility, Taum Sauk reflects Union Electric’s dedication to maintaining reliable and efficient energy generation. The plant not only serves the immediate power needs of the communities it serves but also exemplifies the role of hydroelectric power in a modern energy strategy focused on sustainability and environmental stewardship.
