Britain’s interconnectivity with Europe set to rise sharply
The study shows that installed interconnector capacity in Britain is set to rise to 10 GW by 2023, which is around 25% of average peak GB capacity, and could increase further to 20 GW in the next decade. The contribution to meet GB electricity loads from overseas is already significant – at the time of writing, some 3 GW of imports are on the system, with two-thirds of that coming from France.
Now as much as 16 GW of interconnectors could be in operation in the next ten years – connecting Britain with new markets including Norway, Denmark, Germany and perhaps even Iceland, adds the analyst.
Until now, the impact of interconnectors has been moderated by the reasonably small levels of their transfer capacity, with 4 GW of capacity historically existing to and from continental Europe and 1 GW to/from Northern Ireland and the Republic of Ireland. However, interconnectors either built, in construction or at an advanced state of planning account for almost 20 GW of capacity.
