Flexible Networks

The Flexible Networks project is a major innovation project funded jointly by SP Energy Networks and Ofgem's Low Carbon Networks Fund.

In 2012 we set out to find practical alternatives to costly network upgrades in constrained areas by exploring other ways of unlocking spare capacity. This project has now reached its conclusion and we would like to share our findings with you.   

We are pleased to be able to make available for further research and analysis the source data from the network monitoring carried out for this project, please click here.
