I mean, the batteries are already coming. Ontario is bringing a 250 MW battery facility online point the next two years, as a part of a plan to deploy 1500 MW worth of battery capacity.

That's nearly 10% of our average demand being supplied by batteries, and it's cost effective to do so...

We can charge them with cheap overnight power, and use it to trim our peaks... Or prevent wind turbine from curtailing by starting to charge our battery banks.

12h hours of battery storage for our province should come out to only about 20 billion assuming you can do it with $100/kwh with LFP cells.

Considering we just spent $13 billion on a nuclear refurbishment, this doesn't seem crazy levels of investment at all.

My number might be a bit optimistic, but I'm assuming building the biggest battery plant in the world will net you some discounts.
