The UK is set to break its electricity import record in 2024, with imports already surpassing previous highs, driven by interconnector flows from France and Norway.
New analysis of National Grid Electricity System Operator (ESO) data by the Nuclear Industry Association (NIA) reveals that in the first quarter of 2024, net electricity imports to Britain amounted to a record 9 terawatt-hours (TWh), followed by an additional 14.95TWh from January to May.
This influx of imported electricity is projected to meet the needs of approximately 10.8 million homes throughout the year, potentially reaching 36TWh by year-end – a 46% increase compared to the previous record set in 2021.
The UK’s reliance on imported electricity is primarily facilitated through six interconnectors, with nuclear power from France emerging as the leading source.
Last year, imports from France alone totalled 12.7TWh, predominantly from their nuclear facilities which comprise around 70% of their energy mix.
Norway follows as the second largest exporter to the UK, primarily supplying hydroelectric power.
According to National Grid ESO’s 2024 Summer Outlook, the UK experiences higher electricity prices than its neighbouring countries during summer months, making imports economically favourable.
Tom Greatrex, Chief Executive of the Nuclear Industry Association, said: “Other countries get the jobs, and we get the bill because we have not invested enough in our own nuclear power and other sovereign power sources.
“That underinvestment leaves us with structurally higher prices than our neighbours, and they are making money off our mistakes.
“The next government’s drive to net zero means we must start turning that around by approving a raft of new nuclear power stations alongside major renewable investment, so we get the jobs and the energy security for our future.”
