Newfoundland and Labrador Hydro says many Black Tickle residents should be prepared to go without power overnight after a fire at the southern Labrador community's diesel-generating plant.

A company news release said Wednesday the fire broke out around 6 a.m., causing the plant to shut down, and knocking out power to approximately 100 customers.

Company vice-president Jim Haynes said it could be a while before people get their power back.

"I think people should be prepared to be without power overnight regardless," he said.

"Because even getting generators in we have to muscle them, we have to either fly [them in] or obviously shipping would be difficult, but I mean that's not ruled out. But it's going to be a little challenge to get those things in anyway."

No one was injured in the fire, although heavy smoke and flame was seen at the plant Wednesday morning.

A Hydro crew from Happy Valley-Goose Bay and the fire chief from Cartwight travelled to Black Tickle to assess the damage.

Black Tickle has a population of more than 200 people.
