Harbor Substation Project

New Indoor Substation in Central Anaheim 


Critical Power Source to Provide Reliability and Future Development


Anaheim Public Utilities is planning to construct a new Substation at 131 W. Katella Ave.  The substation will be built inside a building that blends with similar structures in the area. This facility will improve electric service reliability and provide additional power capacity to Central Anaheim.  

Project Description:

The new substation will utilize Gas Insulated Switchgear technology which allows the substation equipment to have a much smaller footprint and be constructed inside an aesthetically pleasing building. All incoming/outgoing electric lines to the substation will be constructed underground.

Once complete, the substation will be outfitted with two transformers that provide enough additional capacity to serve 15,000 customers.

Project Benefits:

  • Harbor Substation will help Anaheim Public Utilities meet existing power demands, future development in the area, and maintain power reliability.
  • This project will help maintain a stable level of electric service in the area during the event of a major power shutdown or service disruption.

Construction Schedule


  • February 28, 2017 Design & Construction Award Consideration by City Council
