BritNed, the subsea electricity interconnector linking Great Britain and the Netherlands, is marking 15 years of electricity flowing between the two countries, delivering more affordable and secure power for millions of homes and businesses.

The milestone comes as National Grid and TenneT Netherlands, the Dutch transmission system operator, sign a new Joint Development Agreement to build on BritNed’s success through LionLink, a hybrid technology designed to maximise the consumer benefits of interconnection and offshore wind.

The proposals sought to remove a 7km section of overhead electricity line and 16 pylons, between Postlip Mill near Winchcombe and Dowdeswell Wood, east of Cheltenham, in the Cotswolds National Landscape and replace it with underground cables. 

Ofgem, the UK energy regulator, ran a 28-day consultation from 1 April 2026 to 5 May 2026, which allowed interested parties to provide feedback on its proposal.

With the consultation now concluded, the regulator has today published its final decision which confirms it will not be funding the Cotswolds VIP project.
