US utility San Diego Gas & Electric announced on June 4 it has five lithium ion energy storage projects totalling more than 80MW and one demand response program equalling 4.5MW approved by the California Public Utilities Commission.

The six projects will improve grid reliability and integrate more renewables in the San Diego and south Orange counties of California. The largest will be built by Fluence in Fallbrook. The 40MW/160MWh battery facility is due to be completed by March 2021.

The second largest will be a 30MW/120MWh storage facility in San Diego by Renewable Energy Systems. The project should be online by December 2019.

The other projects are: a 4MW/16MWh system in San Juan Capistrano by Advanced Microgrid Solutions to be completed by December 2019; Powin Energy’s 6.5MW/26MWh facility in Escondido by June 2021.

The only non-US firm to be contracted in the projects is Italy’s Enel Green Power, which will build a 3MW/12MWh facility in Poway by December 2021.

OhmConnect is providing the demand response programme, which requires customers to conserve energy during heavy peak periods to limit demand on the grid.

By 2030, the utility expects to develop or interconnect more than 330MWs of energy storage.
