Why? What should people know about Texas power grid upgrades?

Best I can see right now is ERCOT and others saying lots of upgrades have been made, but not specifics. I can see ERCOT and the legislature going back and forth on a “market overhaul” that no one can quite agree on yet and which favors more on-demand sources (natural gas and such). Can you point to where people should read about upgrades?

I think there is a bad title here, but that’s not the title at the link. I don’t know where this title came from. OP? The link is a pretty straight forward reporting of this recently released EIA report and doesn’t seem to contain much of the author’s opinion (apart from being on a renewable biased website).
