National Grid has launched consultations for two more multi-billion pound electricity links between England and Scotland. The two projects – Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) – are part of wider plans to create “electricity superhighways” between the two countries. National Grid Electricity Transmission (NGET) is jointly developing EGL 3 with SSEN Transmission (SSEN) and EGL 4 with SP Energy Networks (SPEN).
