United Kingdom – October 13, 2026 -- National Grid is running a transmission build-out that includes a seven-year, £1 billion project to rewire South London through deep underground tunnels, alongside new high-voltage links to carry offshore wind and solar power south from Scotland and the North.
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.
