National Grid’s subsea electricity interconnector portfolio, the largest in the world, has delivered over £1.65bn of benefit for GB consumers since 2023, compared to if the portfolio was replaced with traditional gas generation. This analysis demonstrates the crucial role interconnectors play in lowering energy bills and ensuring security in our energy supply by maximising every available electricity source.
Interconnectors are overwhelmingly benefiting Great Britain.
National Grid is committed to building a resilient, future-ready electricity transmission network that supports the UK’s clean energy goals. Through a robust procurement strategy and building strategic partnerships, we're committed to safely, reliably and efficiently connecting our customers to the network.
As the sole electricity transmission operator for England and Wales, National Grid conducts procurement under the Procurement Act 2023 (PA23). This ensures we deliver value for money, maximise public benefit, and treat all suppliers equally.
Linking UK offshore wind farms directly to multiple neighbouring European countries through high-voltage subsea interconnector cables could cut energy bills for UK consumers, according to a new report published today by RenewableUK and National Grid.
National Grid Ventures (NGV), responsible for building and operating LionLink as part of the commercial arm of National Grid, has published its refined proposals for LionLink, a new subsea and underground electricity cable – known as an interconnector – which will connect an offshore wind farm to Great Britain’s and the Netherlands’ electricity grids.
