May 4 (Renewables Now) - US utility Southern California Edison (SCE) has contracted 770 MW of battery storage projects in a tender to enhance grid reliability and help address potential energy shortfalls identified in the state.

The utility has signed seven contracts for energy storage projects with capacities of between 50 MW and 230 MW. All of the plants will be commissioned by August 1, 2021, SCE said on Friday. Some of them are co-located with solar photovoltaic (PV) farms.

More details on the selected schemes are available in the table.

Selected bidder Project name Location Contract term (years) Contracted capacity (MW)
Southern Power Garland Rosamond, Kern County 20 88
Southern Power Tranquillity Tranquillity, Fresno County 20 72
TerraGen Power Sanborn Mojave, Kern County 10 50
NextEra Energy Resources Blythe 2 Blythe, Riverside County 15 115
NextEra Energy Resources Blythe 3 Blythe, Riverside County 15 115
NextEra Energy Resources McCoy Blythe, Riverside County 15 230
LS Power Gateway 1-2 San Diego, San Diego County 15 100

The additional capacity will help integrate more renewable energy capacity into the grid and will support California's energy transition, addressing certain reliability issues in electricity supply that the state’s Public Utilities Commission (PSC) has identified. The projects will need to be cleared by the PSC and will be submitted for review later this month.

“These new emissions-free projects will help us ensure the reliability of the grid for our customers and integrate an ever-increasing amount of clean renewable energy over the next decade,” said William Walsh, SCE vice president of Energy Procurement & Management.

California has set a goal to cut its greenhouse gas emissions 40% below 1990 levels by 2030.
