Well, it's still not "fixed", but they're making improvements. And FWIW, here is a comparison of my summer electric bills since 2021:
2021
June - 163
July - 214
August - 204
2022
June - 252
July - 321
August - 303
2023 (hottest summer on record)
June - 209
July - 288
August - 237
2024
June - 224
July - 228
August - TBD
We had to take it up the rump in 2022 after that winter storm, but looks like improvements are getting things back to normal.

TL;DR Summary:
The Texas power grid has undergone significant changes following the severe outages experienced during the 2021 winter storm, prompting a rapid evolution aimed at enhancing reliability and sustainability. Texas operates independently from the Eastern and Western grids, allowing for market-driven policies and reduced federal oversight but requiring self-sufficiency in meeting electricity demands within state borders. As the state grapples with increasing population and business growth, including energy-intensive sectors like bitcoin mining, there has been a notable shift towards renewable energy sources such as wind and solar. By 2023, these renewables accounted for nearly a third of the grid's fuel sources, reducing reliance on fossil fuels like gas and coal.
Despite challenges associated with the intermittent nature of renewable resources, advancements in battery storage technology have supported their integration into the grid, helping to stabilize supply during peak demand periods. This transition has not only contributed to preventing outages but has also led to lower electricity costs for consumers. To manage escalating electricity demand—fueled by factors like population growth and climate-driven extreme weather—ERCOT has expanded its capacity, although concerns about grid reliability persist, prompting conservation measures during periods of strain.
Looking forward, Texas is increasingly focused on further developing renewable energy infrastructure while addressing the aging of existing fossil fuel plants. The state's commitment to incentivizing "dispatchable" resources like natural gas and coal aims to bolster grid stability while managing the costs associated with integrating more intermittent renewables. These efforts underscore Texas's ongoing transformation towards a more resilient and sustainable energy future, albeit one that requires careful balancing of technological advancement, regulatory oversight, and consumer affordability.
