Riverside Electrical Substation is a 66 kV substation located in Riverside, California, United States. Owned and operated by Riverside Public Utilities, it serves as a critical node in the city's electrical distribution network, stepping down transmission-level voltage for local distribution. The substation operates at 66 kV, a common sub-transmission voltage level in the United States, connecting the bulk power system to distribution feeders. As a municipally owned utility asset, it falls under the regulatory oversight of the California Public Utilities Commission and adheres to NERC reliability standards for grid stability and safety. Located in an urban area of Riverside, the substation supports the growing residential and commercial demand in the region. Its operational status ensures reliable electricity supply to thousands of customers, contributing to the city's economic vitality and community well-being.

The substation is situated in an urban environment in Riverside, California, where summer temperatures often exceed 100°F, increasing electricity demand for cooling. The facility's 66 kV voltage level is typical for sub-transmission networks that balance capacity with environmental footprint, as lower voltages reduce electromagnetic field impacts compared to higher-voltage lines. Its urban location means it is subject to local land use regulations and community noise ordinances.
