Peninsula Clean Energy Starts Construction of 200-Megawatt Solar Facility

LOS BANOS, Calif.--(BUSINESS WIRE)--California’s largest solar installation built exclusively
for a Community Choice Aggregation (CCA) agency broke ground today in California’s Central
Valley. Peninsula Clean Energy (PCE), the electricity provider for 290,000 San Mateo County
customers, expects the 200-megawatt utility-scale Wright Solar project to come online in late

This is a huge step for Peninsula Clean Energy and our customers,” said CEO Jan Pepper.
“The Wright Solar project moves us toward our goal of providing all customers with 100%
renewable power by 2025. This long-term contract locks in the price we pay for electricity, which
helps ensure that our rates will remain low. The size of the project is unique for a CCA and
positions PCE as a leader in the industry.”

Peninsula Clean Energy has an exclusive 25-year power purchase agreement with Wright Solar
Park LLC to buy the solar facility’s electricity. The project is owned by Centaurus Renewable
Energy and the construction and operations are managed by Clēnera, LLC. The solar facility is
being constructed by Swinerton Renewable Energy with union labor hired from the surrounding
areas. The facility will produce enough electricity to power more than 100,000 San Mateo
County homes a year.

“One of our primary objectives for PCE is to grow the supply of new renewable energy sources,”
said Dave Pine, founding PCE Board Chair and President of the San Mateo County Board of
Supervisors. “With the Wright Solar project, we are helping to fight climate change by adding
200 megawatts of new solar power. We’re also proud that the construction of this project will
create approximately 400 union jobs in Merced County.”
