Solarcity/Tesla Pioneer Utility Scale Energy Storage System
The proposed project is believed to be the first utility-scale system in the U.S. to provide dispatchable solar energy, meaning that the utility can count on electricity being available when it’s needed, even hours after the sun goes down. The 52 MWh Tesla Powerpack lithium-ion battery storage system will feed up to 13 megawatts of electricity onto the grid to “shave” the amount of conventional power generation needed to meet peak demand in the evening from 5 p.m. to 10 p.m.
