OMAHA, Neb. (AP) — The second day of Arctic temperatures across Middle America has prompted rolling power outages in Nebraska and a call for energy conservation in Iowa. Nebraska residents experience some of the coldest weather they’ve seen early Tuesday, putting a strain on the power grid that saw the state’s power utilities implementing rolling outages. Nebraska’s largest utilities — the Omaha and Nebraska Public Power Districts — said the planned power outages were over by midmorning, and they were working to restore power to all customers. But more outages could be required later in the day. In Iowa, where overnight lows dipped to around 30 below zero in some places, MidAmerican Energy issued a plea for residents to dial back power use.
