ST. JOHN’S — Thousands of electricity consumers across Newfoundland experienced a sudden power disruption on Saturday midday following an unexpected technical glitch on the power grid. Newfoundland Power confirmed that a trip on the “Labrador Island Link” was the root cause of the widespread outage.
According to a social media update by Newfoundland and Labrador Hydro, the trip triggered an automatic safety mechanism known as an “underfrequency load shed.” In the event of a sudden system failure, this automated safety feature cuts off power supply to designated blocks of customers to re-balance the grid and prevent a catastrophic, total system collapse.
Newfoundland Power informed CBC News that approximately 73,000 customers across the province lost electricity due to this protective system intervention. Fortunately, utility crews responded swiftly, and power was successfully restored to a vast majority of the affected areas by Saturday afternoon.
Currently, only about 800 customers in the Appleton area remain without electricity while restoration efforts continue. Officials also clarified that two other power outages experienced on Saturday—specifically in the Sunnyside-Clarenville-Bonavista Peninsula region and the Baie Verte Junction-Sheppardville area—were unrelated to the grid glitch and were part of previously scheduled routine maintenance.
