Northumbrian Water is enhancing the way it uses the gas generated from the sewage it treats on Teesside to help power one of its largest sites, thanks to an investment of more than £9.5m.
The new Gas to Grid plant at Bran Sands Regional Effluent Treatment Works on Teesside will not only significantly reduce the cost of running the site, it will also see enough biomethane to fuel 5,000 homes injected back into the National Grid.
Bran Sands is the second Northumbrian Water site to use Gas to Grid, following the establishment of a similar plant at Howdon on North Tyneside in 2015. The investment represents the latest part of the company’s wide-ranging energy management plan, through which it continues to utilise increasing volumes of sustainable energy from a variety of sources.
The Teesside investment will see returns of almost £3m per annum, as a result of saving on its energy bills and returns from a two-tier renewable heat incentive agreement, as well as delivering environmental benefits through the export of the gas.
Northumbrian Water already uses 100% of its sewage sludge to create energy, mainly thanks to the Anaerobic Digestion “Power From Poo” operations at Bran Sands and Howdon, and the Teesside site also generates sustainable power from a 943-panel solar array on its rooftops.
