I have committed the sin of mixing energy with power units.
I think its 300 MWh. Phase 3 just completed. Here is the proposal from Phase 4, which is supposedly going to increase from 300MW(?) to 600MW(?). The proposal is also kinda loose with their units.
300 MW for how long? A second? An hour? A day?
The exact figures:
735.5 MW AC 2,942 MWh
Verified from Minnesota PUC and EQB.

If it’s Lithium-ion battery storage, I’d wager the dis/charge rate is anywhere from 2-4 hours.
Assuming 300 MW, that’s a 600-1,200 MWh battery.
Assuming 300 MWh, that’s a 75-150 MW battery.
