Tesla Completes 20-MW Energy Storage for Southern California Edison

By Editors of Power Engineering

Tesla has completed a 20-MW energy storage system that will ensure reliability for Southern California Edison’s grid.

The battery storage system includes two 10-MW systems, each of which contain 198 Tesla Powerpacks and 24 inverters. This system allows it to be connected to two separate circuits at the Mira Loma substation.

SCE selected Tesla for the project during a competitive bid in September.

“We are very excited to bring this site online,” said JB Straubel, Tesla chief technical officer. “Storage is quite a new thing … and this is a different breed of battery. This is the tip of the iceberg of how much storage we’ll see on the grid.”

The California Public Utilities Commission ordered SCE to ramp up its use of energy storage to help make up for the loss of natural gas storage at Southern California Gas Company’s Aliso Canyon storage facility due to a massive leak.

“This was unprecedented fast action on the part of the CPUC,” said Michael Picker, the commission’s president. “And we are once again stunned by the battery industry to meet our needs. This is another example of progress,” he added, congratulating all the participants.
