The CD4 power plant will be the first geothermal power plant built within the California Independent System Operator (CAISO) balancing authority in the last 30 years. The 16 MW of energy deliveries under the PPA will begin no later than the end of 2021 with an extension option. The PPA is for a term of 25 years and has a fixed price of $68 per MWh. Ormat intends to sell the balance of 14 MW to other offtakers or at the spot market.
“The Colton Electric Department looks forward to taking delivery of energy from a geothermal facility as the cornerstone of our renewable resources,” said, Colton Mayor, Frank Navarro. “CD4 will be a long-term, renewable resource with no greenhouse gas emissions and will provide resource adequacy capacity and energy at an affordable price to Colton’s ratepayers. CD4 will provide almost 25 percent of Colton’s annual energy supplies. This power purchase agreement with Ormat for CD4 demonstrates Colton’s commitment to a green economy with affordable energy prices for our citizen’s while committing to zero emission sustainable resources.”
