The Wilmington receiving station was constructed in 1927, the same year as station B, and was part of the early high voltage (132,000 volt) belt line, a ring of five receiving stations being built at the time to encircle the city. The high voltage coming to the station came from the LA Aqueduct’s hydro-electric plants, and starting in the 1930s, the power from the Boulder Dam. The five substations in the ring provided stepped-down voltage to their respective constellation of distributing stations, which in the early 1940s, numbered around 85 throughout the DWP service area. Wilmington served the electrical demands of the city’s expanding industrial center at the port. It connects now to the Harbor Generating Station, one of four DWP gas-fired plants.
