Thames's Mogden STW rewarded for CHP energy milestone
Thames Water's Mogden Sewage Treatment Works has been recognised with an award after reaching the milestone of generating more than half the electricity it uses from its own biogas, reducing costs and carbon emissions.
The site near Twickenham Stadium was recently recognised at the 2017 Anaerobic Digestion and Biogas Industry Awards for the upgrade of its three combined heat and power (CHP) generators. These produce electricity from the biogas created when sewage sludge is heated and breaks down in the anaerobic digestion process.
The biogas produced at Mogden is converted into electricity each day by the new 6MW CHPs, generating enough energy to power the equivalent of 15,000 homes and used to help run the sewage treatment equipment on the site. This accounts for over half of its total electricity consumption, so significantly reduces the need to use electricity from the national grid and helps bring down Thames Water’s greenhouse gas emissions.
Mogden Site and CHP Manager Ian Ruffell, said: “We’re over the moon with this award which reflects a lot of hard work and skill by our own team, the project team at our Eight20 alliance and our partners at Edina, who worked on the upgrade. To have a sewage works as large as Mogden self-generating more than half of its own energy is a great achievement and it’s all from a source which will never run out, that being the waste our customers send our way each and every day.
Thames Water energy manager, Angus Berry, added: “To be a more sustainable and greener business, our focus is on generating more of our own renewable energy, using less of it and spending less, all of which will reduce our carbon footprint and keep costs down, which can only be positive news for our customers.”
Overall, Thames Water uses CHP engines to generate electricity from sludge at 23 of its sewage works and currently produces over 24 per cent of it electricity needs from them. The company also generates energy using wind power and solar power, and hosts one of the world’s largest floating solar panel farms on its Queen Elizabeth II Reservoir on the outskirts of London.
Thames is working towards its target of producing 33 per cent of the electricity it uses from renewable sources by 2020.
