Sutton Decentralised Energy Network (SDEN) is a ground-breaking initiative to use heat, that would otherwise go to waste, to deliver low-carbon supplies of hot water for heating and domestic use across South London. The SDEN is one of the initiatives run by Sutton Council’s economic development arm, Opportunity Sutton.

They have the potential to deliver heat to 19,000 new homes. At the moment they are working on Phase 1 of their network, which will be capable of supplying 3.3 GWh of heat to about 725 homes and a supermarket at the new Felnex development. That phase alone will save 900 tonnes of CO2 emissions, with future phases expected to increase this to over 5,000 tonnes. They are also looking to expand their network further across South London in the near future.

Councillor Ruth Dombey of Sutton, the leader of this initiative, stated that “SDEN offers developers¬†an alternative to using fossil fuels. By harnessing waste heat from the Energy Recovery Facility in Beddington, we can channel it into homes and premises in south London to provide low carbon energy”.
