The last time I ran the numbers I think Alberta would need about 10% more grid capacity for 50% of regular vehicles(including trucks and suv's) being EV's, not including any large commercial vehicles. So it's not a huge leap, but we will need that mostly as baseload.

Watching generation this cold week we have essentially nothing from solar and wind ranged from about 3% to 10%(currently around 0.4%, so incredibly variable), while we imported about 7% net. To put that in perspective, 7% is about 1 Shepard Energy Centre(the big one for Calgary). So we'd probably need to add 2 of those at minimum, but we also have to replace ~3000MW coal, which is another 4-5. So we should be planning to build at least 6 large NG generating stations to maintain baseload capacity, as we can't rely on wind that fluctuates from near nothing to 10%. Maybe some of that can be offloaded to batteries, but the variable downtime makes that either really expensive or a massive gamble. For instance, if wind represented 30% of our capacity, but drops to only making 5% for a few days, that's 2500MW, or 3-4 large NG plants. I don't imagine batteries would help much in that situation. It's a huge amount of power.

The largest grid battery currently is about 129MWh, so to store 2500MW for 2 days, that's 120 000MWh. 100 times the largest installed.

Sorry, veered a little off topic.
