The California Public Utilities Commission at its March 26 meeting will be looking at a proposed resolution approving cost recovery for a long-term renewable energy power purchase agreement (PPA) between Southern California Edison (SCE) and Tribal Solar LLC.
The 328-MW Tribal Project is located on the Fort Mojave Indian Reservation in San Bernardino County, California, and was developed by First Solar Inc. The Tribal Project will interconnect with the California Independent System Operator-control grid at the Mojave Generation Station located in Laughlin, Nevada.
SCE filed an advice letter in October 2014 requesting commission review and approval of a 20-year renewable energy PPA with Tribal Solar. The PPA resulted from SCE’s 2013 renewable portfolio standard (RPS) solicitation and was executed in July 2014. The project is located on the Fort Mojave Indian Reservation and has a capacity of approximately 328 MW. The expected commercial operation date is in December 2019.
The expected annual generation to be purchased from the project is 830 Gigawatthours (GWh). This generation could count towards SCE’s RPS requirements in Compliance Period 2017-2020.
SCE retained Merrimack Energy Group Inc. as the independent evaluator (IE) to oversee its 2013 RPS solicitation. In addition, Merrimack oversaw the negotiations with Tribal and evaluated the overall merits of the Tribal PPA. The IE states in its report that the Tribal PPA was reasonably negotiated with contract terms that when taken as a whole appropriately protect the interests of SCE’s ratepayers. The IE also concludes that the project is very mature in terms of project development.
