As of March 2024, Great Britain has 9.8GW interconnection capacity in operation. A further 1.9 GW of interconnection is in construction, with 0.5GW expected to be operational by 2025. Anticipated interconnection capacity by 2025 is therefore approximately 10.3GW.

In 2020, the Government set an ambition to realise at least 18GW of interconnection by 2030; this was reaffirmed in 2023.

Two additional interconnectors, totalling 3.2GW, have recently received positive interim regulatory decisions from Ofgem. If progressed, Great Britain will be on track for 13.1GW of interconnection capacity by 2030, and 14.9GW by 2031.

The Government will provide more information on interconnection post-2030 in due course.
