A giant 1.3 GWh Tesla Megapack project is going online in Arizona

A massive Tesla Megapack project with 1.3 GWh of energy storage capacity is coming online in Arizona – making it one of the largest battery systems.

Salt River Project (SRP) and Plus Power LLC are behind the massive project.

Yesterday, they announced that it is coming online and should provide enough power for 76,000 homes:

Salt River Project (SRP) and Plus Power LLC today celebrated two new grid-charged battery storage systems, Sierra Estrella Energy Storage and Superstition Energy Storage. Together, these facilities will add 340 megawatts (MW) / 1,360 megawatt-hours (MWh) of additional battery storage capacity to SRP’s system – enough to power 76,000 residential homes for a four-hour period. The batteries will absorb excess energy when customer demand is lower and store it for use during times of peak demand.

By being turned on, it automatically became the largest standalone battery system in Arizona and one of the biggest in the US.

SRP Vice President Chris Dobson, Plus Power President Alex Fraenkel, Avondale Mayor Ken Weise, and U.S.DOE Deputy Assistant Secretary Jeff Marootian

Plus Power has been using Tesla Megapacks in many of its energy storage projects, like the one that replaced Hawaii’s last coal power plant.

The Megapack has quickly become the go-to solution for large-scale energy storage projects.

Last quarter, Tesla deployed a record amount of energy storage, 4 GWh, and most of that is believed to be Megapacks.
