A planned power outage that affected the entire city of Summerside, P.E.I. on Friday night has some business owners questioning the timing of the repair work.

Maritime Electric knocked out power to the city around 4 p.m. AT to fix some frayed wires.

Gordon Sobey just finished getting his hair cut as the power went out, forcing his barber to close the shop.

"At least we got all the trimming done that we needed to do. The next guy is in more worse shape than me,” he said

But some businesses weren't as pleased.

Convenience store employee Donna Palmer said she never saw the outage coming. She wonders why work to the power grid had to be done during her busiest time.

"It came as a surprise to me. About five minutes after the fact that it went out people were saying, ‘Oh ya, it was a planned outage.’ I didn't know before,” she said.

That's because the city only had two hours to notify 7,000 customers that Maritime Electric was shutting off the power supply to the entire city.

"I feel bad about it because I know the big grocery stores and small grocery stores and all the businesses need the electricity,” said Mayor Basil Stewart.

Other stores did what they could with the lights off.

Wayne Maddox had some intricate jewellery repairs to finish. 

"I have the daylight still. Once it gets dark though, I'm finished,” he said.

A hockey tournament with players from the entire region was put on hold until the power was restored.

About an hour and a half later, power came back on.

By that point many businesses had closed up for the day.

The city is able to generate its own electricity, but Basil said they couldn't get the system online.
