Southampton City Council
Southampton District Energy Scheme (SDES), delivers sustainable supplies of heat, chilled water and power to over 45 energy users in the public and private sectors. SDES is operated by ENGIE working in partnership with Southampton City Council – under the name of Southampton Geothermal Heating Company Ltd (SGHC).
The scheme has been operational for 25 years and it is currently saving around 10,000 tonnes of CO2 per annum, utilising heat from a large scale combined heat and power (CHP), supplemented by geothermal energy and conventional boilers. It also incorporates a district cooling system. The scheme has been awarded the Queen’s Award for Sustainability.
