Britain to rely on EU power imports this winter amid record £4bn import spend

By the Editorial Team · Monday, October 19, 2026

Britain has spent a record £4 billion on electricity imports over the past year, relying heavily on power from the EU and neighboring countries to meet around 10 percent of its total supply. This growing dependence underscores challenges in the UK’s shift to a low-carbon grid, with infrastructure constraints and intermittent wind power driving increased import reliance ahead of winter demand.

Britain is set to rely heavily on electricity imports from the European Union and neighboring countries this winter, following a record £4 billion expenditure on power imports in the year to August, according to data from the Office for National Statistics (ONS). The figures highlight an increasing dependence on external sources, which now account for roughly 10 percent of the UK’s total electricity supply.

The rise in imports is linked to the UK’s transition toward a net zero carbon grid, which has made the domestic electricity system more reliant on wind farms located predominantly in the north of the country. These facilities face challenges such as intermittent output and limited grid capacity to distribute the power efficiently. The surge in power imports notably includes electricity from France, accounting for £2 billion of the total spend, and Denmark, contributing around £450 million. Imports from Ireland have also increased recently, marking a shift as the island typically depends on the UK for backup power.

In August alone, the UK spent £473 million on imports, setting a new record for a summer month—a period that traditionally sees lower demand. While previous higher monthly costs occurred in winter or during the heightened energy market volatility linked to the Ukraine conflict, the current trend points to sustained import reliance irrespective of season.

The UK’s National Energy System Operator (Neso), established two years ago to manage the shift to low-carbon energy, is expected to emphasize the necessity of imports in its forthcoming winter outlook report. Earlier this year, Neso forecasted that approximately 5.5 gigawatts out of the total 60 gigawatts of required generation capacity would need to come from overseas sources. The operator has already issued formal requests for emergency power assistance from the continent twice in the past ten days amid grid management challenges.

These pressures stem partly from infrastructure constraints, particularly between Scotland and England, where transmission cables have struggled to handle power generated by northern wind farms. This bottleneck led to emergency measures and significant operational costs, with Neso reportedly incurring record expenses of around £50 million to maintain grid stability during recent episodes.

Two separate inquiries into a June power supply crisis that raised concerns about potential blackouts are scheduled to be released next week. One, commissioned by Neso, will address allegations of a cover-up attempt, while a regulatory investigation led by Ofgem will focus on the technical aspects of the failures.

The situation has drawn political attention, with Andrew Bowie, the shadow energy spokesman, criticizing the UK government’s approach. He asserted that the high costs and growing reliance on foreign energy expose the country’s vulnerability and argued that Britain could achieve greater energy self-sufficiency by adjusting its policies amid abundant domestic resources.

As the UK heads into winter, the prevailing consensus among energy officials and analysts is that imports will play a crucial role in meeting demand and preventing shortages, highlighting the complexities of the ongoing energy transition.
