The more I look into Texas the more it seems it was an inside attack.
DS insiders giving them a big FU for not being tied into the federal grid.

I thought they were having all the power issues due to the use of green energy intiatives like windmills and solar which are freezing up and snow covered respectively...Is this not the case?

It's complicated. Texas knew solar & windmills could have problems during the winter. So they had small power plants to fill in when this happened. Those were small power plants but the state required those plants to follow green energy regulations. The cost was impossible for those plants so all those plants shut down. On top of that TX power plants didn't winterize their generators so all of them froze up. TX knew they had a problem after the freeze of 2011, but nothing was done about it. So 3M+are without power in TX.

Corruption is showing in Texas’ government.
