The coal-powered electricity-producing plant is question is owned and operated by the TVA, meaning that it is owned by us. The Tennessee Valley Authority was started by the Federal government in 1933:

"President Franklin Roosevelt needed innovative solutions if the New Deal was to lift the nation out of the depths of the Great Depression. And TVA was one of his most innovative ideas. Roosevelt envisioned TVA as a totally different kind of agency. He asked Congress to create "a corporation clothed with the power of government but possessed of the flexibility and initiative of a private enterprise." On May 18, 1933, Congress passed the TVA Act"

"By the end of the war, TVA had completed a 650-mile (1,050-kilometer) navigation channel the length of the Tennessee River and had become the nation's largest electricity supplier. Even so, the demand for electricity was outstripping TVA's capacity to produce power from hydroelectric dams. Political interference kept TVA from securing additional federal appropriations to build coal-fired plants, so it sought the authority to issue bonds. Congress passed legislation in 1959 to make the TVA power system self-financing, and from that point on it would pay its own way."
