Peninsula Clean Energy is to procure 245MW from three California wind projects as part of its goal of providing reliable all-renewable, emission-free power by 2025.
The deals include a seven-year extension until 2030 of an existing 150-MW wind project in Solano County with Avangrid Renewables.
The current five-year term ends in December 2023.
An additional eight years has been agreed with Shell Energy North America (US) for half of the capacity and renewable energy generated by the existing 130MW wind project near Mojave.
The final source will be half of the expected 60MW generated for 20 years from this project being repowered by a subsidiary of NextEra Energy Resources near Bakersfield in Kern County.
The project, which will repower an existing facility by replacing 157 existing turbines with 11 new turbines for Peninsula Clean Energy’s portion, is expected to be operational by September 2021.
The additional wind generation will supplement solar generation – including supply from the newly commissioned 200MW Wright Solar and 100MW Mustang Two Whirlaway projects.
Peninsula Clean Energy chief executive Jan Pepper said: “In order to hit our 100% renewable goal we will need some significant contributions from wind energy.
“We are particularly gratified to have longer-term commitments in a highly competitive market for wind energy projects that will help us further push the envelope in giving our customers clean and affordable power.”
NextEra Energy Resources senior vice president of development Matt Handel said: “We are pleased to work with Peninsula Clean energy to bring additional low-cost, renewable energy to its customers and economic growth to California.
“Once construction on this upgrade is completed, our project partners will enjoy an improved wind project that is more efficient and produces cost-effective energy.”
