 The head of TEPCO, Jo Conn Guild, was vehemently opposed to the creation of TVA, and with the help of attorney Wendell Willkie, challenged the constitutionality of the TVA Act in federal court.The U.S. Supreme Court upheld the TVA Act, however, in its 1939 decision "Tennessee Electric Power Company v. TVA".On August 16, 1939, TEPCO was forced to sell its assets to TVA for $78 million, which included $2.68 million for Ocoee Dam No.
