Maritime Link problem causes power outage in parts of Newfoundland
CBC
A "significant event" involving the Maritime Link system led to a swath of power outages across Newfoundland Monday morning, according to Newfoundland and Labrador Hydro.
In a statement to CBC News, the company said the outages happened after exporting electricity to Nova Scotia.
About 57,000 customers lost power, with most of them having it restored within 16 minutes, said the company.
"After the Maritime Link had been ramped down following scheduled exports to Nova Scotia, it experienced significant power swings which resulted in oscillations in system frequency," said the company in an email statement to CBC News. "This resulted in the activation of the island's under-frequency load-shedding scheme, leading to widely dispersed customer outages."
The company tweeted about the issue just after 7 a.m. but provided few details about the problem.
As of 9:30 a.m., the company said, power had been restored.
The Maritime Link transmits hydroelectric power from Cape Ray to Point Aconi in Cape Breton over 180 kilometres of subsea cables. The $1.52-billion link is part of the Muskrat Falls project.
Electricity was first transmitted over the link between N.L. and Nova Scotia in 2017. It was the first time Newfoundland had been connected to the North American energy grid.
N.L. Hydro says it's still investigating what happened.
