Regarding Highgrove Hydroelectric Plant. After the initiation of Riverside's municipal direct current power system in 1896, the Highgrove plant also supplied some electricity to San Bernardino. In 1898, alternating current generators replaced the original direct current generators. Later the plant was merged into the Southern California Edison Company and only remnants are there now.
