CleanPowerSF Delivers on Promise to Invest in Renewable Energy Projects with New Wind, Solar Developments
New projects expand CleanPowerSF power portfolio and ensure clean, safe and reliable energy for customers for years to come

San Francisco, CA – Delivering on a promise to invest in new renewable energy projects, CleanPowerSF has signed several multi-year deals to build new wind and solar projects that will create more than 600 new jobs and ensure a clean, safe and reliable renewable power supply to customers over the next several decades.
This month, the City’s community choice energy program signed two long-term agreements to purchase the renewable power created from a new 100-megawatt solar photovoltaic power plant to be built in Lancaster, California and a new 47-megawatt wind power plant in Mohave, California. Combined, the projects will generate enough renewable energy to power over 130,000 average San Franciscan households.
The new solar project, called San Pablo Raceway, is expected to begin delivering solar power to CleanPowerSF customers in summer 2019. The 22-year contract is being developed by sPower, the largest private owner of operating solar assets in the U.S. San Pablo Raceway will generate ten full-time operations-related positions and approximately 500 construction jobs (150,000-200,000 work hours) during the 7-8 month construction period.
The new wind project, which expands Terra-Gen, LLC’s Voyager Wind IV facility, located in Kern County, California, is expected to begin delivering wind power to CleanPowerSF customers in winter 2020. The project will create six full-time positions and at its peak, approximately 100 construction jobs during the six-month building phase.
Terra-Gen, LLC is a renewable energy company focused on developing, owning, and operating utility-scale wind, solar and geothermal generation. The company owns 1,051 megawatts of wind, geothermal and solar generating capacity throughout the western United States.
The San Francisco Public Utilities Commission (SFPUC), which provides operational oversight on rates and charges, contracts, and organizational policy, unanimously approved the agreement.
“Choosing CleanPowerSF means investing in clean energy projects that will bring cleaner, greener electricity to San Francisco. We are thrilled that the San Pablo Raceway and Voyager Wind IV Expansion projects will be built to serve the residents and businesses of San Francisco,” said Barbara Hale, SFPUC Assistant General Manager for Power.

“sPower is excited to partner with CleanPowerSF to provide clean renewable energy for San Francisco,” said Hans Isern, sPower’s SVP of Power Marketing. “We're proud that San Pablo Raceway will be a major contributor to the ambitious clean energy goals of CleanPowerSF and the State of California.”
“Terra-Gen's portfolio is one of the largest renewable businesses in the United States. We’re thrilled to be able to partner with CleanPowerSF on such a large scale and continue providing clean energy to San Francisco and the Golden State,” said Terra-Gen, LLC CEO James Pagano.
CleanPowerSF also recently signed a short-term agreement with Calpine Energy Services, LLC., America's largest generator of electricity from natural gas and geothermal resources, for energy from the Geysers geothermal plant located in Sonoma County. The 5-year deal will supply CleanPowerSF with 5 megawatts of renewable energy this year, increasing to 20 megawatts in 2019 and 2020, and 25 megawatts in 2021 and 2022. Calpine has also made community benefit commitments to support climate education programming for youth as a part of the agreement.
