UK–Netherlands interconnector at 15: LionLink design lessons for grid engineers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
A subsea electricity interconnector between the UK and the Netherlands has completed 15 years of continuous operation, as the two countries’ transmission system operators sign a new agreement to develop the proposed LionLink project. The existing high-voltage direct current (HVDC) cable has been a key cross-Channel asset for power flows and grid balancing, informing design, reliability and maintenance strategies for future links. LionLink is expected to use next‑generation HVDC technology and multi‑terminal configurations, with implications for offshore grid integration, seabed cable routing and long-term marine asset durability.
Technical Brief
- Existing UK–Netherlands subsea interconnector has achieved 15 years of uninterrupted operational availability.
Our Take
Fifteen years of continuous subsea interconnector operation between the United Kingdom and the Netherlands gives LionLink backers a strong reliability reference case, which typically helps in securing regulatory approvals and long‑tenor project finance for new HVDC links.
