They faced questions on the need to winterize the system and whether different forms of energy would perform better in extreme weather, according to the Texas Tribune.
- The of head of the state's power grid operator, the Electric Reliability Council of Texas, announced his resignation after the storm, as well as four members of its board of directors.
