SWANS - Southwest active network system

This is the South West Active Network (SWAN) which is a project set up to meet new contractual requirements between National Grid Electricity Transmission (NGET) and SEPD in May 2017 for certain GSPs. It was introduced because the amount of Distributed Energy Resources connected, and connecting to the distribution networks was believed by National Grid ESO to be impacting on the transmission network.

What does it mean for me and other customers?

The SWANs Active Network Management System will allow more customers to connect to the distribution network ahead of transmission related reinforcement. By using an ANM system, we are also able to defer traditional reinforcement at the distribution level, to keep customers’ bills as low as possible.
