So the day peaked at 85 GW of load, and they got down to only 130 MW of spare capacity. Just 0.15% from running out. And they never asked for conservation? Is it normal to go that close to the edge without trying to cut load?
This is a state that should basically be peppered with residential rooftop solar. Of course, there's zero chance of any sort of state governmental policy to help incentivize it in deep red state land. But if recent history has shown anything, I would consider it a primary feature of any home in Texas to be relatively grid independent with its own generating capacity and storage.

A lot of the incentives are from local power companies like Oncor, but one notable state-wide incentive is that solar installations are exempt from property tax by state law.
I dunno why people act like Texas is staunchly anti-renewable. TX state politicians have said some goofy stuff about "windmills freezing over", but overall Texans are extremely pro-wind and pro-solar. It's a huge economic driver for a large part of the state, and it's seen as an overall part of Texas's strong energy industry, complimentary to oil rather than as a competitor to it. George Bush and Rick Perry were both Republican governors but both were _very_ pro-renewable and oversaw massive booms in wind energy especially. In 2005 Texas (including Perry at the time) passed a law to invest billions of state dollars into building transmission lines specifically to make it feasible for renewable energy generation in west Texas to bring power to the populated areas in the east, which is attributed to the massive wind boom. Abbot, on the other hand, has sadly not been very pro-renewable, but much of the state still is.
