Kind of. Texas now has two DC interconnects to the two North American grids,
which allows them to share power without having frequency management issues
or accept government regulation from the FERC (which does include a lot of
silliness but also includes standards for safety margins that are worth
following).
Texas has had DC grid ties for years, they're just not high enough capacity to
make much difference statewide (aggregate of around 1 GW I believe). Peak
summer demand is somewhere around 85 GW.
It's doubtful that any realistic grid ties would have done more than reduce
the scope and duration of the rolling blackouts during winter storm Uri.
Demand was around double available capacity...a shortfall of at least 35 GW.
There's been a huge change in potential winter demand as residences moved
from gas heating to heat pumps and population increased. With the entire state
below freezing (and many areas below 0 F) there were a lot of heat pumps
running in "emergency" mode. In our case that changed our power consumption for
heating from 5 kW to 15 kW. I'm not sure anybody knows what the "real" demand
was or would have been. We only had power about 1/3 of the time (15 minutes on,
30 minutes off) during the height of the rolling blackouts, but when we did
have it we were running all out...a space heater trying to keep our gecko
alive, the heat pump running in emergency mode and the (electric) oven on with
the door open. I'm guessing 20+ kW. I think we hit a low of 50F in the house.
Even with rolling blackouts we used a normal February's amount of electricity
in four days.

ERCOT only includes residential and commercial demand in their demand calcs. ERCOT does not include gross industrial power generation from the refineries and chemical plants, only the net that is sold to the grid. The industrial power generation in Texas is over 20,000 MW, it is a hard number to get a hold of and changes over time as plants are added or closed.
For instance, the big Alcoa Aluminum plant in Rockdale, Texas used about 600 MW for the nine aluminum potlines before they were closed down in 2008. Whereas the four older lignite units could generate about 900 MW (net) until the oldest three 1950s units (360 MW net) were replaced in 2009 with a single unit that could generate 580 MW (net) for a plant total of 1,137 MW (net).
