Power System Reliability Program


The Power System Reliability Program provides a blueprint for ensuring continued reliable energy service for future generations of Los Angeles residents. LADWP implemented the Power System Reliability Program through a two-pronged approach—rebuilding infrastructure and proactive maintenance—and will invest more than $1 billion in the program over the next 5 to 15 years. The program is funded through a power reliability surcharge.

The goals of the program include:

  • Reducing Temporary Circuits
  • Replacing Distribution Transformers, Poles, Underground Cables, and Substructures
  • Reducing Frequency and Duration of System Interruptions
The table and graphs below detail the progress of the Power System Reliability Program.
