MONTRÉAL – Extreme cold forced Hydro-Québec to temporarily suspend its energy exports to Massachusetts just one week after inaugurating its new line.
Hydro-Québec and the Massachusetts Executive Office of Energy and Environmental Affairs both confirmed the news, which was first reported by specialized media outlet E&E News.
The decision came as last weekend’s polar vortex led to a significant increase in demand in Quebec.
There is less water in Hydro-Québec’s reservoirs at the moment due to a three-year drought.
Hydro-Québec confirmed it suspended deliveries to Massachusetts over the weekend and for one hour on Tuesday morning out of a need to prioritize Quebec customers.
The Massachusetts Executive Office of Energy and Environmental Affairs said it is aware of the constraints faced by Hydro-Québec during the period of extreme cold.
