Power was restored to the main campus of the Southern York County School District on Wednesday morning so that all the schools could open following a two-hour delay.

The power went out at about 11 a.m. on Tuesday, and crews worked through the night to restore power by Wednesday morning, said Wayne McCullough, chief financial and operations operator.

The outage affected Susquehannock High School, Southern Middle School and Southern Elementary School.

"It was a problem with our main distribution line," McCullough said.
