Texas (ERCOT) hit an electricity demand record this week to the point that there was a risk of blackouts. That didn't happen, and they do have a lot of new generation in the works (wind, solar, and gas alike, along with energy storage). However, it goes to show that being a fully deregulated market (ie. utilities don't directly own any generation or have any customers - they're just responsible for the transmission & distribution infrastructure) does work for them, even without any real environmental policy (while having the most wind and fastest growing market for solar).... Of course, wind & solar isn't really a political issue in other Great Plains and Southwest states, as well..... Hopefully the Southeast will finally learn soon enough, but I'm not optimistic, except for Florida and North Carolina....
