Thames Water procured 12mWe CHP units from Edina to generate electricity and heat from the sewage gas at their London based water treatment plants.
The power produced will be used to supplement site demand. The engine jacket water heat will be used for digester heating with the exhaust fed to waste heat boilers for steam production to assist the advanced digestion process.
