3. Electricity Transmission Network

Great Britain's National Electricity Transmission System (NETS) must continue to adapt and be developed so power can be transported from source to demand, reliably and efficiently.

The results on this page will be used in the NOA 2020/21 to present an assessment of the ESO’s recommended reinforcement options to address the potential future NETS boundary needs.
