Like it's pulling a lot of weight because it's 80% of the capacity if nothing's going wrong! If it was 100% then maybe 40 GW of thermal capacity would _also_ be offline.
ERCOT assumed 0% from Wind. Instead we're getting 25% They assumed 100% from gas. Instead we're getting 50% (or 70% or whatever). You look at that and tell me gas is what's performing well here, and the segment that should be expanded. (EDIT: Sorry, I think your original thing was "all in nuclear." I think I read nuclear was also having some issues but it's at least not the "more gas is the solution for a situation where gas is failing" narrative)
I get that wind + solar can't cover everything, but right now what we're seeing is massive failures from gas. In a universe where we had more wind + solar, there could likely be more energy going around right now.
