Our Interactive Map
Use this map to navigate through the Electricity Ten Year Statement (ETYS) and the Network Options Assessment (NOA). The map is illustrative and shows identified needs to move energy from point A to point B. It does not represent specific cable routes.
Key features of this map:
Electricity Ten Year Statement (ETYS)
The ESO’s view of future transmission requirements and the capability of Great Britain’s National Electricity Transmission System (NETS) over the next 10 years.
