Understanding Santa Clara's Energy Market
Santa Clara's energy landscape is unlike that of most California cities. Instead of receiving electricity from a large investor-owned utility, residents and businesses are served by Silicon Valley Power, the city-owned electric utility. Natural gas, meanwhile, is delivered by Pacific Gas and Electric. Large commercial customers may also explore on-site generation, battery storage, and specialized energy services to manage costs and reliability.
This structure matters because Santa Clara is home to one of the largest concentrations of data centers in the country. These facilities require massive amounts of reliable power, and their growth is reshaping how energy is planned, purchased, and delivered in the city. Whether you are a homeowner, a small business, or a large facility manager, understanding your energy supply options can lead to meaningful savings and improved resilience.

Frequently Asked Questions
Can I choose a different electricity provider in Santa Clara?
Most residents and small businesses receive electricity from Silicon Valley Power, the city-owned utility, and do not have the option to switch to another retail provider.
