Texas lawmakers to hold ERCOT under microscope for winter grid disaster KTRK Share: HOUSTON, Texas (KTRK) -- As the Texas Legislature prepares to hold hearings Thursday into the failure of the state's power grid during last week's historic winter storms, many questions remain for both storm victims and lawmakers alike. ABC13 hosted a town hall Tuesday night, gathering one of the state's foremost experts on the power grid and four legislators from Houston who will investigate why millions of Texans were left in the dark, with some still trying to recover without access to water. At least 20 deaths have been attributed to the winter storms, which brought the coldest February temperatures in 122 years to our region. Analysts say four million homes lost power, heat or water at some point during the disaster.
