The Osage Dam, with a capacity of 208 MW, ranks as the 1,331st largest power generation facility among over 10,000 plants in the United States, reflecting its relatively modest contribution of 0.02% to the national energy supply. Specifically, it holds the 94th position out of 1,469 hydroelectric plants across the country. Commissioned in 1935, this facility has been a long-standing contributor to the region's energy profile, which is predominantly fueled by natural gas. The dam employs traditional hydroelectric technology, utilizing the flow of water to generate electricity, a method that not only provides reliable power but also helps in flood control and water management. In the immediate vicinity, Osage Dam is surrounded by a mix of energy generation facilities, including the Fairgrounds Oil Plant (68.3 MW) and the Niangua Hydro Plant (3 MW), providing a varied energy landscape. This local energy cluster underscores the importance of diverse energy sources in maintaining grid reliability. The United States' total capacity reaches approximately 1,386,385 MW, dominated by gas, making Osage Dam's hydroelectric generation a small yet vital part of the overall energy equation. Operated by Union Electric Co. in Missouri, Osage Dam exemplifies the critical role of aging infrastructure in the nation's energy portfolio. As the U.S. continues to explore sustainable energy solutions, the Osage Dam serves as a reminder of the importance of maintaining and modernizing existing hydro facilities to enhance their efficiency and environmental impact.
