The Southern California Public Power Authority, or SCPPA, agreed to purchase 16 MW of electricity from Ormat Technologies Inc.'s planned 30-MW Casa Diablo IV geothermal project in Mammoth Lakes, Calif.
The power purchase agreement has a 25-year term and a fixed price of $68/MWh. Deliveries under the contract will begin no later than the end of 2021 with an extension option, according to a March 20 news release.
SCPPA will resell the output to the city of Colton, Calif.
Ormat said the Casa Diablo-IV project will be the first geothermal power plant built within the California ISO balancing authority in the last 30 years. The company plans to sell the remaining 14 MW to other offtakers or at the spot market.
