Hetch Hetchy Power

The San Francisco Public Utilities Commission (SFPUC)—a department of the City and County of San Francisco that delivers drinking water to 2.7 million people and collects and treats wastewater—owns and operates Hetch Hetchy Power. This power represents some of the cleanest energy available in California.

For over 100 years this system—which utilizes the gravity flow of the City’s water from source to tap—has operated without producing any carbon emissions nor any radioactive byproducts. Hetch Hetchy Power energizes vital San Francisco services as well as a growing number of residential and commercial customers. In all, we provide nearly 20% of San Francisco’s total electricity.

Any municipal facility and many large commercial and residential developments are eligible to be Hetch Hetchy Power customers, providing an independent alternative to PG&E and Direct Access.
