Tesla And PG&E Are Working On A Massive ‘Up To 1.1 GWh’ Powerpack Battery System

The title of this post, is the same as that of this article on electrek.

This is the first two paragraphs.

For the past few months, Tesla and CEO Elon Musk have been teasing a giant battery project that would dwarf even the company’s 129 MWh Powerpack project in Australia.

Today, we learn that Tesla is working with PG&E on a massive battery system with a capacity of “up to 1.1 GWh” in California.

It certainly, is a big lithium-ion battery.

  • It will be able to provide 182.5 MW for four hours.
  • It looks like it could be the largest  lithium-ion battery in the world.

It is worth comparing with the Castaic Power Plant, which is also in California.

  • This is a pumped storage plant.
  • It can produce 1566 MW and has a capacity of 12470 MWh.

This Google Map shows the plant.

Note.

  1. The power plant is also part of the California State Water Project, which transfer water from North to South.
  2. The low-lake is Elderberry Forebay to the East.
  3. The high-lake is Pyramid Lake to the North.

It is a complicated system that includes the Angeles Tunnel, which takes water between Pyramid Lake and the Castaic power plant.

It cost a lot more than the 1.1 GWh battery, but it can generate a lot more power.
