Goes to show the government should have mandated a VTG system.

Wow that’s as much battery as 33,500 Model Ys.

Totally, it’s actually not that many vehicles! And it implies a value of thousands of dollars per EV in its lifetime grid balancing.

In a package the size of only 12,300 elephants!

It’s actually pretty incredible. About 8 years ago SMUD cancelled their Iowa Hill pumped storage project. The stats are pretty comparable to this one, except for physical size! About $1B, 400 MW, 4,800 MWh of storage, by pumping 6400 acre feet of water 1200 feet uphill (7.9 million cubic meters of water 365 meters uphill).
