WORTHING, UK - Veolia is installing new combined heat and power (CHP) engines at three of Southern Water’s treatment works - Budds Farm and Fullerton in Hampshire and Gravesend in Kent.
The work is part of Southern Water’s wider project to generate even more renewable energy by upgrading CHP units at five of its sites.
Each new Veolia project includes the design, installation and operation of the biogas cogeneration units by Veolia’s specialist CHP team, and adds to the systems already serving seven other Southern Water treatment sites.
These CHP will now deliver around 48.3 gigawatt-hours (GWh) of renewable electricity each year, estimated to save 8,800 tonnes of CO2 emissions.
Southern Water currently generates 17% of its electricity from 16 CHP sites.
Around 190 UK wastewatersites now produce biogas to generate electricity which is used on site or exported to the national grid.
Gavin Graveson, Veolia’s COO public and commercial, said: “Recent estimates show that biogas from the sludge resource could deliver an estimated 1,697GWh each year - enough electricity to power over half a million homes. This latest extension of the use of CHP by Southern Water clearly demonstrates its commitment to further the sustainability of the water industry.”
