Summary
The council adopted a resolution approving a 15-year renewable energy credit purchase agreement with Desert Breeze Solar LLC to help meet state Renewable Portfolio Standard targets; the contract supplies about 49,000 PCC1 credits annually at $31 per credit.
The Roseville City Council adopted a resolution Oct. 15 approving a 15-year power purchase agreement (PPA) to acquire renewable energy credits from Desert Breeze Solar LLC as part of the utility’s compliance with California’s Renewable Portfolio Standard (RPS).
Petra Wallace, Roseville Electric’s power supply and portfolio administrator, told the council the contract will deliver about 49,000 PCC1 renewable energy credits each year and "cover about 7% of our 2030 renewable target." The contract is a fixed-price deal at $31 per credit with anticipated commercial operation in mid-2027 and a total contract value of about $22,800,000 over the contract term.
Wallace explained that California’s RPS requires utilities to increase renewable generation and that Roseville Electric must meet a 60% renewable requirement by 2030. She said the city is currently in compliance period 5 (2025–2027), when the average renewable requirement is 52% of Roseville’s load and that 65% of qualifying renewables must come from long-term contracts (10 years or longer).
Roseville already has long-term contracts that supply part of its compliance portfolio, Wallace said, and the Desert Breeze purchase aligns with the city’s 2023 integrated resource plan. Sean Matcham, chief operating officer for Roseville Electric, said the city will only pay for credits after they have been delivered and transferred, which staff described as a risk-mitigation measure.
On the council floor, no members requested further public comment and the council adopted Resolution No. 25-332 authorizing the city manager to execute the PPA and related documents. The vote was unanimous, 5-0.
The contract is intended to help Roseville Electric meet long-term RPS targets and to secure PCC1-category renewable credits within the California Independent System Operator region.
