SCE Selects Six Companies for 125-MW of Grid Edge Technologies

LCG, September 19, 2016--Southern California Edison (SCE) recently announced that it has selected six companies to construct 125 MW of distributed energy storage and demand response for its Preferred Resources Pilot (PRP), a long-term testing ground to learn how distributed energy and the grid can work together.

The companies selected for the second round of PRP contracts include: Advanced Microgrid Solutions, with a 40-MW contract for demand response (DR) with energy conservation and batteries; Convergent, with 35 MW of batteries; Hecate with 15 MW of batteries; NextEra with 10 MW of batteries and 10 MW of demand response, NRG with 10 MW of solar-storage "hybrid," and residential battery startup Swell with 5 MW of batteries.

SCE is offering 10- to 20-year contract terms, with delivery set to begin between 2018 and 2020. These six companies will now pursue developing sites and customers within specific areas of Orange County served by SCE's Johanna and Santiago substations, where reliability is a concern given (i) the closure of the San Onofre Nuclear Generating Station (SONGS), (ii) the planned closures of natural-gas-fired power plants serving the area, and (iii) the changing patterns of grid power generation over the course of the day, largely driven by the growth rooftop solar PV.

The PRP was started at the same time as a testing ground for these technologies on a more local scale, as well as to develop the technology expertise to expand SCE's smart grid capabilities to include more distributed energy resources (DERs) at a broader scale. The initial procurement was primarily for rooftop solar and energy efficiency, unlike this new round, which includes batteries for all the projects.
