United Kingdom – October 16, 2026 -- National Grid is advancing a portfolio of transmission projects that includes a seven-year, £1 billion programme to rewire South London through deep underground tunnels, begun in Spring 2020, and several 2 GW high voltage direct current (HVDC) links between Scotland and England.

Eastern Green Links add 2 GW corridors from Scotland to England

EGL1 is a 2 GW HVDC link between the Torness area in East Lothian, Scotland, and Hawthorn Pit in County Durham. EGL2, also rated at 2 GW, will run from Peterhead in Aberdeenshire to Drax in North Yorkshire. EGL3 and EGL4 are intended to raise network capability to connect new offshore wind farms.

National Grid Electricity Transmission is also developing Sea Link, a planned high voltage undersea connection between Suffolk and Kent. Separately, a project to strengthen the Scotland-England network would connect new energy sources in the Scottish Borders.

Two 2GW HVDC links target Scottish and North Sea generation

EGL1 is a two-gigawatt (GW) high voltage direct current (HVDC) link between the Torness area in East Lothian, Scotland, and Hawthorn Pit in County Durham. EGL2, also rated at 2GW, will run between Peterhead in Aberdeenshire and Drax in North Yorkshire. Eastern Green Link 3 (EGL3) and Eastern Green Link 4 (EGL4) are intended to increase network capability to connect new offshore wind farms.
