Tesla begins construction of 730 MWh energy storage system in CaliforniaAugust 8, 2020
Tesla and Pacific Gas and Electric Company announced that they have received all approvals from the authorities and are starting to build a battery energy storage system at a distribution substation in Moss Landing, California. According to Electrek, the system will consist of 256 Megapack units and will store twice as much energy as all Tesla batteries sold in the last three months – 730 MWh.
Tesla first announced negotiations with PG&E back in the summer of 2018. The companies quickly agreed on a joint project and submitted an application for approval to the California Public Utilities Commission (CPUC). The project was under consideration by the department for almost two years, but was still approved.
The 730 MWh Battery Energy Storage System (BESS) will be built jointly by Tesla and PG&E at a distribution substation in Moss Landing. Construction work will begin shortly and should be completed by early next year, with the super-battery scheduled for commissioning in the second quarter of 2021.
“Battery systems play an important role in improving the efficiency and reliability of power grids, integrating renewable resources while reducing dependence on fossil fuels. Our project will serve as an alternative to more expensive traditional solutions, resulting in lower overall costs for our customers. The scale, purpose and flexibility of the Megapack project at Moss Landing will play a big role in future energy storage designs, ”said Fong Wan, senior vice president of energy policy and procurement at PG&E.
The finished project will consist of 256 Tesla Megapack units, which will be installed on 33 concrete slabs. In addition, in the future, the partners plan to expand the project to 1.1 GWh of total capacity, which will mean the installation of an additional 130 Megapack units. So far, this is the largest project of all that Tesla intends to implement in the next 3 years, which has received all the necessary permits.
PG&E said the Megapack batteries will save the company more than $ 100 million over the project’s 20-year life.
