Students went home early when the power cut off at the Clearfield Area Junior-Senior High School.
This was the scene around 1 p.m. as buses filled the circle earlier than usual.
The three-phase power line from PenElec stopped working around 11:30 a.m. and was back up by 3 p.m., facilities director Rick Bunning said.
They do have some back-up power in the school, and everything is alright for Thursday since the power is back on, Bunning said.
The district just had a two-hour delay on Tuesday due to concerns over the early-morning icy weather.
