Met-Ed confirmed Wednesday, thousands of York County residents were without power.
Central York School District posted on its website that students were being dismissed at 11:30 a.m. Other businesses, like the York Galleria, were affected for only 10 minutes until power was restored.
According to a Met-Ed spokesperson, a 115 kilovolt transmission line tripped at 9:49 a.m., which resulted in outages to several Met-Ed substations in the York County area. Approximately, 6,000 customers were affected. Service was restored to about 3,200 customers at 10:06 a.m.
Power was restored a few minutes after students were released, a school employee said.
The remaining 2,800 customers, Met-Ed reported, should have service restored shortly. The cause has not yet been determined.
