Clean energy makes a difference and so do predictable rates. With our electricity services you get both.

We believe all San Franciscans should have access to affordable, clean electricity. That's why, as a not-for-profit power provider, we set our rates based on the actual cost of getting power to our customers. 

To provide predictability for our CleanPowerSF and Hetch Hetchy Power customers, the San Francisco Public Utilities Commission (SFPUC) aims to update its electricity rates just once a year.
