Interconnector investment reshapes outlook

The IFA link is jointly owned by National Grid and France's RTE.
The connection has operated for 40 years and can supply electricity for about three million British homes annually.
The upgrade is part of National Grid's broader network investment programme through March 2031.

National Grid has announced a new investment programme for the Interconnexion France-Angleterre (IFA), extending the UK-France electricity link until at least 2050. Reuters reported the announcement on 29 October 2026, citing the company.

What has changed since our last report

The latest development is the planned life-extension work for IFA, rather than a change to the previously reported earnings outlook. The programme will upgrade technical equipment, buildings and facilities at the interconnector site.

IFA is jointly owned by National Grid and French grid operator RTE. The link has completed 40 years of operation, is the UK's largest subsea connection by capacity and can supply enough electricity for about three million British homes a year. It normally imports power from France to Britain but can also operate in the opposite direction.

At Lang & Schwarz, the National Grid share traded at EUR 15.07 on 29 October 2026 at 18:35 Berlin time. That was 2.80 percent above the EUR 14.66 quote recorded in the latest relevant own report dated 27 October 2026. This comparison is separate from a Xetra closing-price comparison.

Investors should weigh the strategic value of maintaining cross-border power capacity against the execution and financing demands of a large regulated-network investment plan. The IFA announcement supports the group's long-term infrastructure narrative, but it does not by itself establish a change in earnings or valuation.
