Saft Supplying Battery Technology For SMUD PV Project


Saft will provide its lithium-ion (Li-ion) battery technology to supply renewable energy storage for the Sacramento Municipal Utility District's (SMUD) photovoltaic storage pilot program at Anatolia III, a high-penetration PV community within SMUD's service territory.

SMUD was awarded $4.3 million from the U.S. Department of Energy to conduct a two-year pilot project to examine the value of distributed PV coupled with energy storage in 15 homes and three sites on SMUD's distribution system.

The project will allow assessment of the PV system and energy storage capability and determine how well the storage systems perform during periods of peak demand, according to Saft. Through this pilot, SMUD will gain insights into the technical and economic feasibility of using distributed storage to enable higher penetrations of PV within its service territory.

The role of the battery system is to provide efficient energy storage so that solar power can be time-shifted to support SMUD's super-peak from 4 p.m. to 7 p.m.- particularly when PV output drops off after 5 p.m. According to Saft, Li-ion is the only technology that meets the project's need for 20-year battery life in a range of demanding environmental conditions.
