SDEN – What is it?

Sutton Decentralised Energy Network (SDEN) is a truly sustainable initiative to use heat, to deliver low-carbon supplies of hot water for heating and domestic hot water use across South London.

We’re already working on Phase 1 of our network which will be capable of supplying 3.3 GWh of heat to around 725 homes and a supermarket at the new Felnex development.

That will save 900 tonnes of CO2 emissions with future phases expected to increase this to over 5,000 tonnes.

We are exploring connections to existing sites, including St. Helier Hospital and Carshalton College, as well as residential developments.

The boroughs of Croydon and Merton are also working with us to expand the network across South London. Homes on the Felnex Estate could be using SDEN as early as spring 2017.

“SDEN offers developers an alternative to using fossil fuels. By harnessing heat from the Energy Recovery Facility in Beddington, we can channel it into homes and premises in south London to provide low carbon energy. We want to help create a better environment for everyone and any income generated will be reinvested back into local services.”
