Texas death toll from February winter storm climbs to 111

• The majority of the deaths were associated with hypothermia, and the death toll may continue to rise as officials link more deaths to the storm, AP notes.

The big picture: State officials testified before a House Energy subcommittee on Wednesday during Congress' first hearing on the widespread failure of Texas' power grid. 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 head of the Electric Reliability Council of Texas, the state's power grid operator, announced his resignation after the storm, as well as four members of its board of directors.
