A £700,000 combined heat and power (CHP) plant is being installed by Southern Water at it’s wastewater treatment works on the Isle of Wight. The plant will capture biogas created during the sewage treatment process.

The plant will produce renewable energy to the power and heat networks using anerobic digestion, the surplus electricity will be exported to the power grid. It will also use heat from engine and exhaust systems to warm treatment tanks and quicken the bacterial digestion of the waste.

The project forms part of Southern Water’s programme to self-generate 20% of it’s electricity needs from renewable sources by the end of the decade. Southern Water hopes that the CHP plant will reduce it’s carbon emissions from the site by up to 1,4 tonnes per year.

Southern Water project manager, Morné Cloete said “Harnessing recoverable energy through the use of CHP plants is just one of the innovative ways Southern Water is helping reduce its impact on the environment by reducing our carbon footprint while also cutting our energy costs.”
