Newfoundland and Labrador Hydro executives are cautioning about the potential for rotating power blackouts due to insufficient electricity supply to meet the demand. The Bay d’Espoir plant, the island’s primary generating facility, is currently completely offline for the first time since 1967.
In case of outages, power will be selectively shut down in various neighborhoods or communities without prior notice, according to Byron Chubbs, Newfoundland Power’s vice-president of engineering and energy supply. The anticipated duration of these rotating outages is around 60 minutes per area to ensure continuous electricity distribution across the island.
Although there is uncertainty about the power grid reaching a critical state, officials are closely monitoring the situation, particularly focusing on Saturday evening. Customers are advised to prepare by checking their generators, charging electronic devices, and having flashlights readily available.
The power warning issued by Hydro on Friday was prompted by nearing maximum capacity due to heightened power demand and ongoing issues with frazil ice at the Bay d’Espoir plant. Frazil ice, composed of small ice crystals in supercooled water, can accumulate and obstruct water intakes, affecting facilities like hydropower plants.
Efforts are underway, including the deployment of a team with specialized equipment, to clear the ice at the Bay d’Espoir plant. Newfoundland and Labrador Hydro is working diligently to secure additional power sources for the island, with Muskrat Falls currently providing a significant portion of the electricity supply. Plans are also in place to import electricity from Nova Scotia through the Maritime Link to supplement the power grid.
Repairs at the Holyrood generating plant are being expedited to address the current situation where only one of its three generators is operational. The hope is that warmer weather in the coming days will help mitigate the risk of a power emergency. Additionally, measures are being taken to explore energy sources from regions like New England and Quebec, with a focus on maintaining a stable power supply amid the challenging conditions.
