The Fountain Green Power Plant was built 1922-23 out on flat land below the foothills of the San Pitch Mountains. Unlike hydroelectric plants powered by water from mountain streams, it used water from Big Springs, which collected behind an earthen dam and was transported by a conduit pipe to the Fountain Green powerhouse. The powerhouse is a relatively small structure holding only two turbine units. It has a simple architectural style containing elements of Art Moderne. Two ancillary smaller brick buildings are close by; in 1988 one was in use as a garage and battery house, the other as storage. The plant is located by the intersection of Big Spring Road (or N. 500 West Street) with the driveway to the Fountain Green Fish Hatchery, on the northwest side of Fountain Green. The power plant was decommissioned in 2014.
