You’re both sorta wrong (and sorta right).
Texas’s grid is crap. It’s far too unregulated and operators do not focus on the right sorts of improvements that will enhance grid stability. Sure, production is great, which means prices are low, but when you ignore warning calls, you invite disaster. They knew, and they chose not to enforce regulations that other states enforce. Other states deal with far colder weather. This was a failure of regulation. And they also fail to maintain basic system design, so a normal power fault can grow out of control to take out power to most of west Texas.
Anyway - sorry. That’s just a pet annoyance of mine. I hate it when pro-corporate governmental policies are seen as a positive thing based on limited metrics. Lower rates amidst poorer performance is not what I’d consider a marker of success. People die, have their homes and property damaged, and lose a lot of money during power outages.
While the chronic underinvestment in their infrastructure is still an issue, the recently announced infrastructure investment is geared toward transmission and generation, which wouldn’t (directly) address their reliability woes.
It seems to me that the goal of this allocation is to build generation capacity in states with space for solar (and possibly wind, although the Biden admin isn’t trying to bootstrap the wind industry in the U.S.). And also build transmission capacity to get that power out of those states and into other areas of the country. (And possibly back in, should they face local problems.)
My hunch is that they want to get some of that renewable power out west, to have a backup the next time the Colorado river/areas that currently get power from the Hoover Dam suffer from a drought, and to feed power up to the east coast so they can decarbonize more easily.
