Tesla’s Megapack, the company’s upcoming new stationary energy storage product, will be reportely installed at Tesla’s giant 1.2 GWh energy storage project with PG&E in California.

Acording to information was reported by electrek.co, Tesla's new large container-size energy storage system will to debut in its upcoming project commissioned by PG&E at the Moss Landing substation.

The report claims that, the Megapack consists of a 23′-5″ (7.14m) x 5′-3″ (1.60m) battery system, which the company mostly installs back to back with another unit.

According to Tesla’s plan, they will deploy 449 Megapacks at the site, which is said to have a total capacity of 1,200 MWh. As a result, Megapack seems to have a capacity of 2,673 kWh. That’s more than 12 times the capacity of Powerpack 2 in a package that could potentially fit about 8 Powerpacks.

The California Public Utilities Commission approved the project last month and along with 3 other energy storage system, the new energy storage capacity is so important that it will replace three gas power plants.

PG&E says that they aim to bring the energy project online by the end of 2020.
