NU-Link is a proposed cross‑border electricity interconnector project intended to link Great Britain and the Netherlands, with a design capacity of approximately 1,200 MW. The project was promoted by the NU‑Link Consortium and has been assessed within Ofgem’s third cap & floor window (Window 3 / ...

NU-Link effectively cancelled following Ofgem confirmation of cap and floor rejection on 12 November 2024 due to deliverability concerns. Ofgem stated that the developers had not submitted sufficient evidence to demonstrate the 1.2 GW GB-Netherlands interconnector could become operational by end of 2032. The project had previously had its revenue application declined in the same Window 3 Initial Project Assessment. No further development activity has been reported.
On 24 February 2023, Ofgem opened a public consultation on its minded-to decision regarding timelines and incentive changes for the Third Cap and Floor Window for interconnectors, under which NU-Link had applied. The NU-Link consortium submitted a detailed response letter dated 21 March 2023, welcoming greater flexibility such as project-specific Regime Start Dates and a guaranteed 25-year regime, but expressing serious concerns about the proposed 2032 Backstop Date and associated needs-case reassessment risks for projects like NU-Link.

The NU-Link Consortium applied for Ofgem’s cap and floor regime in the third application window (Window 3) for interconnectors, making the 1.2 GW NU-Link GB–Netherlands HVDC link one of seven projects assessed under this window, which ran from September 2022 to January 2023.
NU-Link’s cap and floor application under Ofgem’s third window was ultimately unsuccessful: Ofgem signalled an intended decision in March 2024 to reject the project on deliverability grounds, listing NU-Link among six of seven Window 3 applicants proposed for rejection, and Frontier Power later confirmed that the NU-Link project did not receive Ofgem’s Window 3 approval.
Frontier Power reports that the NU-Link interconnector has been developed with financial support from utility partners in Japan and Germany, providing development funding for the planned 1.2 GW HVDC link between the UK and the Netherlands.
NU-Link is being developed by the NU-Link Consortium, with Frontier Power indicating that it is developing the 1.2 GW UK–Netherlands HVDC interconnector together with utility partners from Japan and Germany, reflecting a joint development and shared-ownership structure for the project.
