UK approves Sea Link grid upgrade

Highlights

UK government approved National Grid's 2 GW Sea Link undersea electricity connection between Suffolk and Kent, designed to power 2 million homes.
Sea Link forms part of broader electricity infrastructure acceleration including the creation of the Great British Grid and reforms to let businesses build their own grid connections.
Sea Link approval follows support for major solar projects: Great North Road Solar and Biodiversity Park (800 MW capacity) and Frodsham Solar's combined generation and storage.

Sea Link approval and project scope

As reported by GOV.UK, the government has approved Sea Link, a 2 GW undersea electricity connection developed by National Grid between Suffolk and Kent.

The link is designed to carry enough electricity to power the equivalent of 2 million homes, moving power from where it is generated to where it is needed. Officials say the project will ease pressure on the grid and reduce the need to pay generators to switch off output when the network cannot transport their electricity.

Energy Minister Michael Shanks says Britain needs to rebuild the national grid so renewable energy projects and businesses can connect, supporting economic growth and cutting exposure to volatile global fossil fuel markets. He says stronger network infrastructure helps deliver homegrown power, improve resilience and bring bills down over time.

Wider grid reforms and energy investment push

The decision forms part of a broader government effort to accelerate electricity infrastructure as demand for grid access rises. It follows the Prime Minister's announcement of the Great British Grid, a publicly owned body within Great British Energy intended to bring together public and private investment to speed up network upgrades.

The government is also advancing reforms aimed at allowing developers and businesses to build their own grid connections where appropriate, with the goal of reducing delays and lowering costs. Ministers are presenting the measures as part of a wider growth and energy security strategy.

The Sea Link approval also comes after backing for two major solar projects, Great North Road Solar and Biodiversity Park near Newark in Nottinghamshire, and Frodsham Solar in Cheshire. Great North Road Solar and Biodiversity Park is expected to have 800 MW of generating capacity, enough to power the equivalent of about 400,000 homes a year according to the developer, while Frodsham Solar combines solar generation with battery storage.
