Introducing Eastern Green Link 1 (EGL1)
EGL1 is a two-gigawatt high voltage direct current electrical connection to be built between Torness in East Lothian, Scotland and Hawthorn Pit in County Durham.
The multi-billion-pound project is being developed through a joint venture between SP Energy Networks and National Grid Electricity Transmission.
EGL1 is designed to unlock Scotland’s renewable energy reserves by scaling up the UK’s capacity to transport clean energy from where it is generated to where it is needed.
Through its multi-directional design, it will also increase the resilience and stability of the UK’s transmission networks.
Works to construct EGL1 started in March 2025, with the aim of being fully operational by 2029. Connections works started in England in 2024.
Once complete, EGL1 has the capacity to deliver enough electricity for two million homes.
