Electric Engineering and Operations

Palo Alto's electric utility system---
empowering you every day!

The job of maintaining and operating the entire electric distribution system falls to both the Engineering and Operations Divisions of the department. The Engineering Division is also responsible for the engineering and construction involved in providing new services and for the on-going electric projects budgeted in the Capital Improvement Program.

Undergrounding Overhead Lines
Since 1965, the Utilities Department has had an ongoing Capital Improvement Project (CIP) to underground overhead utility lines

Prior to an area being selected and proposed for undergrounding, the City's Electric Utility engineering staff must determine whether the local telephone and the Cable TV (CATV) companies will also be willing to underground their lines.  Hence, underground district areas selected need to meet not only the City guidelines for undergrounding, but also the California Public Utilities Commission guidelines, which dictate what areas local telephone and the CATV companies can underground. 

The areas shown on the Proposed Electric Underground Program Plan meets these standards and were chosen for the next 5 years.

Capital Improvement Program Details



The Electric Utility is proud to have earned this designation by the American Public Power Association based on our superior reliability, safety and system improvement record.
