> MISO

As a retail electricity customer, I vastly prefer whatever is going on in their operational context.

I live 10 miles from the "border" between ERCOT and MISO and I've got a lot of experience with both, particularly in disaster scenarios. ERCOT is a total shitshow when it comes to the edges. The fuel mix in MISO is pretty terrible for the environment, but it is also unbelievably reliable. The Mississippi River is not to be underestimated in its logistical impacts. The price of natural gas drives the daily fuel mix proportions, but it doesn't affect the available base capacity and its financial status (fully amortized for over a generation). If natural gas gets expensive in ercot and the wind isn't blowing, there isn't anything else to give. MISO has 2-3x the coal and nuclear capacity that ERCOT does.
