The power was out for about an hour for close to 2,000 Maritime Electric customers in Charlottetown early Wednesday afternoon.
The power went out shortly after 1 p.m. The Maritime Electric outage map showed around 1,985 customers without power, with outages in an area from Winsloe to Charlottetown Airport and south to the harbour.
A Maritime Electric spokesperson told CBC News crews patrolled the area but could not find any issues.
The grid was re-energized a little after 2 p.m., and power came back for customers without any reported problems.
