Southern California Ed looking to buy 50 MW from Geyser geothermal facility

The California Public Utilities Commission at its May 26 meeting is scheduled to look at a resolution from staff recommending approval of Southern California Edison’s (SCE’s) request to enter into a renewables portfolio standard (RPS) power purchase agreement with Geysers Power Co. LLC.

SCE’s renewable energy power purchase agreement (PPA) with Geysers Power, a unit of Calpine (NYSE: CPN), complies with the Renewables Portfolio Standard (RPS) procurement guidelines, the resolution said.

In October 2015, SCE requested review and approval of this 10-year renewable energy PPA with Geysers. The PPA was executed through SCE’s 2014 RPS solicitation (2014 RPS RFO). Pursuant to the PPA, RPS-eligible generation will be purchased from the Geysers facility which is located in Sonoma and Lake counties.

The supplying facility that is contemplated by the Geysers PPA is a 50-MW portion of an existing portfolio of geothermal facilities totaling over 725 MW. The project is located in the Geysers Known Geothermal Resource Area. Each Geysers power plant is interconnected to one of four transmission lines owned by Pacific Gas and Electric (PG&E): the Geysers-Eagle Rock 115 kV, Geysers 12-Fulton 230 kV, Geysers 17-Fulton 230 kV or Geysers-Lakeville 230 kV transmission lines.

Pursuant to the Geysers PPA, SCE is to begin purchasing generation from the Geysers facilities beginning Jan. 1, 2018. The expected annual generation to be purchased from Geysers is 438 Gigawatt-hours (GWh). The generation could count towards SCE’s RPS requirements beginning in January 2018.

The generation to be delivered pursuant to the Geysers PPA is from an online and operating facility that has been certified by the California Energy Commission as RPS-eligible and is managed by an experienced generator, Calpine, said the resolution. It is reasonable to expect that Geysers will meet the terms and conditions of its PPA.
