On Wednesday, the PG&E-backed Elkhorn Battery Storage Facility was unanimously approved by the Monterey County Planning Commission as the second element of what would be one of the largest energy storage projects in the world.
Located on a 4.5-acre portion of the PG&E substation off Dolan Road and Highway 1, the project will include the installation of 268 Tesla-manufactured Megapack lithium-ion battery units in 17 modules resembling metal storage containers with the capacity to store up to 730-megawatt hours of renewable energy sources during off-peak hours.
The project is the second such initiative at the site after Vistra Energy won planning commission approval in May last year for an even larger, 1,200-megawatt-hour battery energy storage project on the adjacent Dynegy power plant grounds. That project is already under construction, according to county staff.
