Newfoundland and Labrador Hydro says a major generator is out of service for the winter, raising the prospect of rotating blackouts if demand for power can’t be managed.
One of three generators at the main Holyrood generating plant was damaged in an intense blizzard earlier this month.
Jim Haynes, vice-president of regulated operations, says the company can usually meet power demand in winter with two generators and other power sources.
But as a precaution, he says Hydro may ask residential and commercial customers to cut use at peak times.
Highest demand is usually on cold, windy days between 6 a.m. and 9 a.m., and between 5 p.m. and 6 p.m. from December to March.
Haynes says if demand can’t be reduced through conservation, the company will work with Newfoundland Power to rotate short blackouts at peak times.
