The site of the existing Lockhart Hydro Project was originally developed by the state of South Carolina as a canal lock system in the 1820’s. In 1893-94, the original canal was enlarged and a dam was built to supply the newly constructed Lockhart Textile Mill with water for its hydromechanical water wheels. The current Lockhart hydroelectric facility was developed for the purpose of supplying electricity to the textile mill and later to the surrounding communities. In 1918 modifications on the 1.5-mile power canal and construction of the current power house began, both which were completed in 1920. The power house contains five vertical-shaft Francis turbines that were rehabilitated in the late 1980’s.
