             | winterize for the marginal once-a-decade blizzard any more
             | than utilities; around half our homes have relatively
             | inefficient resistance heaters as opposed to furnaces.
             | 
             | We have a lot more growth in the past few years than most
             | other places, both in relative terms, and in absolute (big
             | state + high growth introduces more absolute friction than
             | small state). Demand is forecast to rise over 20% from 2024

             | So no wonder our reserve margins run thinner when we're
             | already having to build at such speed just to keep pace
             | with regular demand.
             | 
             | Texas has been building a ton of wind and solar to
             | supplement generation capacity and is taking some
             | leadership in the next-gen nuclear stuff for a reliable
             | base load, but in the mean time the shortage of CCGTs is
             | going to bite in a state where demand goes up this much,
             | this fast. SB6 passed this summer also should help with
             | reasonable control and oversight.
             | 
             | ERCOT actually does a pretty okay job, all things
             | considered; it's hard to invest heavily in winterization
             | for rare events when you're having to invest heavily in new
             | generation to keep up with steadily increasing baseline

       | Feels like that statement deserves to be contextualized with
       | weather data. There were a few summers leading up to that where
       | all of the major metro areas shared concurrent record high heat
       | days, and sometimes coincided with poor air quality from
       | wildfires (meaning more people closed their windows and ran AC

       | 
       | They mention it here, but then don't talk about whether similar
       | circumstances have been faced since. Don't get me wrong, this is
       | encouraging, but the article invited this kind of reaction by
       | putting "leaving rolling blackouts behind" in the title.
       | 
       | Funny enough, if you look at the article's original title via the
       | URL slug, it was much more measured:                 california-

         | This is underselling it, if anything. The multi-day heatwave
