IFA2

IFA2 links Great Britain and France by HVDC cable between Daedalus converter station, Lee-on-Solent, Hampshire (linked to Chilling substation) and Tourbe converter station, Normandy (landfall Merville-Franceville-Plage), in service since 2021. The figure below is the flow this half hour from Elexon’s interconnector outturn; the capacity the register’s.

Grid connection (TEC)1,100 MW to GB · 1,150 MW from GB — NESO Interconnector Register, 1 September 2026

Two figures, two questions. IFA2’s headline rating is 1,000 MW; its grid connection right, which is what the percentages on this page are measured against, is 1,100 MW to GB and 1,150 MW from GB. A rating describes the cable, a TEC is the capacity registered for its connection to the GB system, and they are not obliged to match. The figure in this page’s search description is the registered one.

The second France link, sharing IFA's operator but on an entirely separate route — it lands at Lee-on-Solent rather than Kent, and reaches the grid through Chilling substation. The operator's page publishes no route detail; these rows come from Ofgem's post-construction review.
