Where does SMUD get your power?

We get power from various sources, including hydropower, natural-gas-fired generators, renewable energy such as solar, wind, hydro and biomass, and power we purchase on the wholesale market. Our goal is a balanced and sustainable mix of sources. Our biggest single source is the Cosumnes Power Plant and we are always adding to our green energy sources.

​Power sources

Natural gas

To offer the best price and reliability we completed the 500-megawatt Cosumnes Power Plant in 2006. The gas-fired plant, in southern Sacramento County, generates enough electricity to power 450,000 single-family homes.


SMUD's Upper American River Project (UARP), with 11 reservoirs and eight powerhouses, is the cleanest and most economical power source we have. In a normal water year, the UARP provides roughly 1.8 billion kilowatt-hours of electricity, providing approximately 20 percent of SMUD’s power needs. Operating and maintaining our hydro facilities requires a license from the Federal Energy Regulatory Commission (FERC). A new 50-year license was issued in July 2014.

Solar Power

SMUD has been a leader in solar power for over 30 years and has continued to be a solar pioneer. Our Rancho Seco Solar project is a prime example of how we're sourcing more renewable energy and looking towards a sustainable future. We also help homeowners and partner with local businesses to determine if solar is right for them.

Solar for your home

As a SMUD customer, you can put the sun to work with your own solar power system and generate your own energy for a better and cleaner Sacramento.

Solar for your business

Community solar

Solar is for everyonand we’re bringing it to our community.

Battery storage

To get even more out of a solar system, consider adding battery storage to your home or business.

Wind power

Wind power is one of SMUD most economical resources.

The Delta breezes of Solano County are producing electricity for thousands of SMUD customers. Located in the Montezuma Hills near Rio Vista, SMUD’s wind farm was developed in 1994 and continues to expand. The three sites in operation have 107 turbines and produce 230 megawatts of clean power. A fourth phase is expected to be operational in 2023. SMUD studies the wind patterns and picks the best spots for the turbines to take full advantage of the winds that whip in from the coast, squeeze through the Carquinez Straits, and spill into the Delta. The site is one of the best locations in all of California for wind generation.
