Power has been restored in Repulse Bay.
The community was in the dark for several hours yesterday, after the power went off in the morning.
The Qulliq Energy Corporation flew staff in from Iqaluit and Rankin Inlet to deal with the problem.
The company says power was restored to everybody in Repulse by about 5 p.m. last night.
The company says it's still trying to figure out what happened, and what to do next.
In an interview yesterday, Qulliq president and chief executive officer Peter Ma said restoring power was a top priority.
"Our entire focus right now for the residents of Repulse is to get the power restored as quickly as possible," he said. "I'd rather send more resources than not enough resources to make that happen."
Repulse Bay's power plant was built in 2000 and was last upgraded in 2008.
