Tesla and PG&E Building World Largest Energy Storage Facility

Tesla in partnership with The Pacific Gas and Electric Company have started the construction of the largest energy storage facility in the world, which is set to be finished by end of year.

Back in Febraury, Officials in Monterey County gave the green light on a massive clean-energy battery farm project in Moss Landing spearheaded by Tesla and PG&E that officials say would be the largest of its kind in the world, that project has now started.

The super advanced energy storage facility will use hundreds of lithium batteries to store the clean-renewable energy and then use existing power lines to transmit energy.

According to Tesla, the Megapack will act as a sustainable alternative to natural gas “peaker” power plants. Peaker power plants fire up whenever the local utility grid can’t provide enough power to meet peak demand. They cost millions of dollars per day to operate and are some of the least efficient and dirtiest plants on the grid. Instead, a Megapack installation can use stored excess solar or wind energy to support the grid’s peak loads.

With this world class energy storage facility and other storage products built by Tesla, Powerwall and Powerpack, Tesla’s total global footprint is now clearly more than 2 GWh of cumulative storage. With Megapack, this number will continue to accelerate exponentially in the coming years. This is an amazing news for Tesla energy business and investors.

The battery park will be able to dispatch up to 730 MWh of energy to the electrical grid at a maximum rate of 182.5 MW for up to four hours using 256 of Tesla’s lithium-ion (Li-ion) Megapacks. Tesla and PG&E will have the option to upgrade Moss Landing’s capacity to bring the system up to 1.2-gigawatt-hours which could, according to Tesla, power every home in San Francisco for six hours.

In comparison, the current world’s largest energy storage facility is the Hornsdale Power, Australia, built by Tesla with the Li-ion battery, with a capacity of 150 MW, a duration of 1.2 hours. Once this Moss Landing is upgraded to the 1.2 GW capacity as anticipated, its storage capacity will be approximately ten times larger than Australia’s Hornsdale Power station. The next largest Li-ion storage system in the world is the United Kingdom’s Stocking Pelham station at 50 MW.
