Overview
Distributing Station 140 is a substation in Los Angeles, California, operated by the Los Angeles Department of Water and Power. It handles voltages of 34.5 kV and 4.8 kV, serving the local electrical grid.
Distributing Station 140 is a substation located in Los Angeles, California, United States. It is owned and operated by the Los Angeles Department of Water and Power (LADWP), the largest municipal utility in the country. The substation operates at voltage levels of 34.5 kV and 4.8 kV, indicating its role in distributing electricity from transmission lines to local distribution networks. As part of LADWP's infrastructure, this substation falls under the regulatory oversight of the California Public Utilities Commission (CPUC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. The facility is situated in an urban environment, serving a dense population center with high electricity demand. Typical substations of this scale in the United States are equipped with switchgear, transformers, and protection systems compliant with IEEE standards. The substation plays a critical role in maintaining grid stability for the Los Angeles area, which experiences peak demand during summer months due to air conditioning loads. Its urban location requires careful integration with surrounding infrastructure and adherence to local safety and environmental regulations. The facility contributes to the resilience of the regional power grid, supporting residential, commercial, and industrial customers.
Environmental context
Located in an urban area of Los Angeles, the substation operates in a region with a Mediterranean climate, characterized by hot, dry summers and mild winters. The high population density and associated electricity demand necessitate efficient grid management to minimize environmental impacts. The substation's equipment is designed to minimize electromagnetic field exposure and noise, in compliance with local ordinances. Its role in distributing power helps reduce transmission losses compared to longer-distance lines.
