Our Presence in California

The largest 100% renewable energy company in the state

Founded in 2009 and headquartered in San Francisco, Pattern Energy is helping provide low-cost renewable energy to millions of Californian ratepayers, more than any other company in the state. 

We are involved in community giving throughout the life of our projects. Acting as a good neighbor benefits both the communities where we develop and the long-term success of our facilities. A Community Benefits Program will support the local economy and ensure benefits to the region have a lasting impact through sponsorships and donations.
