According to a Newfoundland and Labrador Hydro spokeswoman, an “underfrequency load shedding” event responded automatically to the trip in order to protect the power system, resulting in a loss of electricity for approximately 15,000 Newfoundland Power customers.
“We had plenty of generation reserves available, so we were able to call Newfoundland Power right away and say, ‘You can start putting your customers back on,’” said the Hydro spokeswoman.
The outage lasted approximately 20 minutes. It was the second day in a row that generating Unit 3 in Holyrood tripped. That unit is the only one currently operating in Holyrood. The spokeswoman said Hydro is still investigating what caused the trip.
Island-wide power outages reported
Power outages have been reported from St. John’s all the way to Port aux Basques and in most areas in between this morning.
According to Newfoundland Power’s website, the outages are connected to a loss of power supply from Newfoundland and Labrador Hydro. The outages started shortly before 9:45 a.m.
A spokeswoman for Hydro contacted by The Telegram shortly after the outages were first reported said she was still gathering information about the situation. As of 9:55 a.m., generators used by Hydro were producing 713 megawatts of power.
According to Newfoundland Power’s website, a time for power restoration has not been established.
