The first Tesla Megapack was installed at the PG&E Moss Landing substation. The project will be commissioned in Q2 2021 and will become one of the world's largest lithium-ion energy storage systems.
In late July, Tesmanian reported that Pacific Gas and Electric Company (PG&E) and Tesla began construction of a 182.5-megawatt (MW) lithium-ion battery energy storage system (BESS) at PG&E’s electric substation in Moss Landing in Monterey County.
The system will be designed, built, and maintained by PG&E and Tesla, and will be owned by PG&E. The goal of PG&E is to launch the system in early 2021 and have it fully operational in the second quarter of 2021. Upon commissioning, the Moss Landing substation system will become one of the world's largest lithium-ion battery energy storage systems.
PG&E today announced that the first Megapack has been successfully installed.

PG&E predicts Moss Landing BESS will save more than $100 million over a 20-year lifespan. The BESS was approved by the California Public Utilities Commission in November 2018 and by the Monterey County Planning commission in February 2020.
It includes the installation of 256 Tesla Megapack battery units on 33 concrete slabs. Each unit houses batteries and power conversion equipment in a single cabinet. Transformers and switch-gears will also be installed along with the Megapacks to connect energy stored in the batteries with the 115 kilovolts (kV) electric transmission system.
The BESS will have the capacity to store and dispatch up to 730-megawatt hours (MWh) of energy to the electrical grid at a maximum rate of 182.5 MW for up to four hours during periods of high demand. PG&E's agreement with Tesla contains an upsize option that can increase the system’s capacity to up to six hours or 1.1-Gigawatt hour (GWh) total.
