High winds appear to be to blame for the outages, but Met-Ed and PPL did not immediately confirm when Daily Voice contacted them on Monday afternoon.
Some areas only lost power for a few seconds to approximately 30 minutes, but others are still in the dark.
Over 2,000 customers in Adams, Cumberland, Dauphin, Lancaster, Lebanon and York counties remain without power as of 3 p.m., according to each companies outage maps.
PPL outage map shows power is expected to be fully restored between 7:30 and 8:30 p.m.
It is unclear when Met-Ed power will be fully restored.
