In 1895, the first powerhouse was built in Calaveras County in Angels Camp.

“Besides providing water to the Utica Gold Mining Company’s mill in Angels Camp, its canal supplied the mine, via a hydroelectric plant, with the first electricity produced in Calaveras County.

The Utica Mining Company built this powerhouse in Angels Camp along Angels Creek in order to supply additional electricity to Utica and other mines in the area.

This powerhouse was the fourth to be built in California and the eighth to be built west of the Rocky Mountains. After only three years, the Angels Powerhouse was upgraded by the Utica Company’s subsidiary, the Stanislaus Electric Power Company.
