Imports and exports are nearly balanced when you consider that is 1% of the total TWh produced on the west coast.

Being able to import a few percent when you need it and export a few when you don't without having to spin something down is pretty important to having a stable power grid.

The reality is that there is no dividing line between Canada and U.S. when it comes to electricity. Power grids cross the 49th at will. In California, you're on the same interconnection as Vancouver and Calgary.

Conflict would disrupt power in both countries, and much further from the border than you may suspect.

When I worked in energy, trading was entirely on a futures market. Real time load balancing was a mechanical process.

I don’t buy it. Massive generators larger than the Canadian market go down from time to time. There’s dozens of contingencies in place.
