About Severn Trent Green Power Coleshill

Severn Trent Coleshill is a 2.4MW food waste AD plant located on the outskirts of Birmingham adjacent to Severn Trent Water's Coleshill sewage treatment works. The plant was opened in February 2015 and will process just under 50,000 tonnes of food waste per year which will generate renewable energy to operate the sewage treatment works site as well as exporting surplus electricity to the grid.

The site was completed in just 12 months and is made up of 5 digester tanks and large reception building with 2 de-packaging units and 2 Jenbacher CHP units which are maintained by Severn Trent’s own highly skilled service technicians.

Severn Trent owns and operates 35 digestion facilities within their region including the 3.3MW Stoke Bardolph crop digester in Nottingham as well as the new Minworth biomethane gas-to-grid plant which became operational in 2014. With AD and biomethane, as well as renewable assets within wind, hydro and solar, Severn Trent currently generates 30% of its total energy consumption from renewable sources.
