 Jason Ryan, executive vice president of CenterPoint Energy, said power had been restored to more than a million homes and businesses since barrel-made landfall in Texas Monday, and the company expects to get hundreds of thousands of more customers back online by Sunday, but many more will have to wait much longer. During a news conference Thursday, Lt. Gov. Dan Patrick pushed CenterPoint to work harder to relieve residents who have been without power for days and have been forced to seek air conditioning in community cooling centers and meals from food and water distribution points.
