Park Substation

Anaheim Unveils Cutting-Edge Technology with Dedication of Park Above Electric Substation

Anaheim Public Utilities, in a partnership that included the city’s Community Services Department as well as some of the nation’s top energy contracting and consulting firms, today dedicated Park Substation, the first underground electric substation in the United States. Adding to the uniqueness of the substation is the fact that it sits below Roosevelt Park, a 2-acre facility that serves the East Anaheim neighborhood.

The electric distribution station has the capacity to serve 25,000 current and future residential customers. It uses state-of-the-art technology in substation design with Gas Insulated Switchgear (GIS), which reduces the required space for the substation to approximately 30 percent of a conventional station design. The use of this technology is more common in Europe and Japan.
