Utility Resources Supply Information

The mission of the City of Palo Alto Utilities (CPAU) is to provide safe, reliable, environmentally friendly and cost-effective utility services. Read more below about these services. 


Effective January 2013, Palo Alto achieved an "all green" carbon neutral electric supply portfolio. Palo Alto gets its electricity from several sources. The exact numbers from each source vary annually.


 The City uses a "market-based" purchase strategy. This means that gas rates change every month based on market prices.  The City of Palo Alto adopted a carbon neutral gas portfolio in 2017. Click here to learn more


Palo Alto is fortunate to get its water from the Hetch-Hetchy system, one of the most pristine, high-quality sources in the country. Like all Californians, we face the risk of not having enough water to meet ever-growing needs in some years; a challenge that is not going away. Recurring drought cycles are a permanent feature of water supply in this state. Learn more about our water supply and through our Urban Water Management Plan

Infrastructure Projects


 CPAU is always performing ongoing maintenance on its equipment. Several infrastructure projects to replace aging lower voltage lines are ongoing. The new, higher voltage lines will better serve Palo Alto's growing electric needs. 


 CPAU leads the industry with an aggressive capital improvement and maintenance program, continuing our work to upgrade, replace and improve the gas distribution infrastructure to reliability and safety. 


 Palo Alto's water supplier, the San Francisco Public Utilities Commission (SFPUC), completed the Water System Improvement Project (WSIP) to replace a 4.8 billion dollar infrastructure improvement program on the Hetch-Hetchy system. This project will replace aging infrastructure and improve seismic reliability. 

  • CPAU continues a proactive program to upgrade its own water distribution pipelines as well. The City is undergoing a multi-year project to rehabilitate, replace and install new reservoirs and wells. These efforts will bolster our local emergency water supply system. 
  • Both the SFPUC and CPAU projects are investments in the long-term viability of our superior water supply. 


 CPAU continues to maintain and replace sewer lines that are reaching the end of useful life. Since July 2011, the City has engaged in an industry-leading program to search for and identify any gas line crossbores into sewer pipes. This program will help ensure customer safety when dealing with blocked sewer lines.
