UK approves 2 GW Sea Link electricity transmission connection
The government announced approval for National Grid’s mainly offshore connection between Suffolk and Kent as part of Britain’s electricity-network upgrades.
What the record says
The Department for Energy Security and Net Zero announced on October 30 that the UK government has approved Sea Link, a 2 GW electricity transmission connection between Suffolk and Kent that will run mainly offshore. National Grid is developing the project.
The department says the link is intended to move electricity from generation areas to where it is needed and ease network constraints. Those are expected benefits, not measured results from an operating connection. The announcement places the decision within the government’s programme of nationally significant clean-energy infrastructure approvals.
