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.

They are demonstrating geothermal boreholes with plasma drills now. The plan is to do a 20km deep borehole, in just 100 days, next year.

If that is actually achievable, we can drill a borehole next to every single coal plant in the world, and run the turbine off of super critical geothermal steam... Basically forever.

Because you don't just use all solar?

You mix solar, with geo-seperated wind farms, and existing hydro resources.

It tends to be sunny during the day and windy at night. It tends to be sunny in the summer and windy in winter. They kind of naturally dovetail. Also, off -Shore wind has incredibly high capacity factors...

Batteries, especially cheap and durable LFP batteries can definitely help cover peak loads, and then we start talking long scale storage, with things like ammonia / hydrogen storage, where we can start storing weeks worth of energy.

And even still, you probably have natural gas turbines hanging around for a few decades for those low periods, but we use them less and less as we increase storage and over build our wind and solar installs.

Huge thermal storage for industrial process heat is also coming.

The problem here is that a lot of the energy is going to keeping the battery warm enough to accept charge, because they're charging the battery outside, in the cold. Of the 1500 watts from the plug, less than 500 watts is actually going into the battery, with 1000 watts going to heat.

Move up to 3000 watts, and you're still throwing 1000 watts to heat, but 2000 watts will be going into the battery, and your charge time drops to like, 2.5 days instead of 10.
