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 ongoing electric projects budgeted in the Capital Improvement Program (CIP).
Utility Undergrounding Projects
Since 1965, the Utilities Department has had an ongoing program to convert overhead utility lines to underground. Our underground conversion project map shows areas of the City with underground utilities, as well as currently proposed underground projects.
Prior to an area being proposed and selected for utilities undergrounding, the City must coordinate with local telephone and Cable TV (CATV) companies to also underground their equipment and lines. Underground "district" areas need to meet City guidelines for undergrounding, as well as California Public Utilities Commission guidelines, which dictate requirements for local telephone and CATV companies.
