Wednesday teatime, 10 January at 17.50, demand reached 94.2MW which equals the amount of electricity being drawn during another cold spell in 2021.
Guernsey Electricity can take a maximum of 60MW from the undersea cable link with France.
This means the North Side power station was used heavily this week, particularly on Wednesday, as this graph shows.
Demand caused some outages in the Vale and Castel areas and Jon Sexton, head of engineering and design at the States owned company, said there were other glitches:
"The additional demand on the electricity network caused some localised supply interruptions and other minor issues, such as lights dimming or minor display errors on appliances. The company’s engineering teams responded to any issues as they occurred and any inconvenience caused is regretted."
“As more Islanders explore options such as electric heating or electric vehicles, such demand is forecast to rise in the future.”
