Construction begins on the UK's largest anaerobic crop digester at Stoke Bardolph.

GHA Livigunn working in association with Interserve Project Services have begun work for Severn Trent Water on the UK’s first large scale CHP plant that plans to provide 15GWh of electricity power generation each year from Bio Solids.

The Stoke Bardolph project involves the construction of a 2 MW Energy Crop Digestion and CHP Plant on land adjacent to Stoke Bardolph Sewage Works in Nottingham. The plant will provide power generation from bio solids which are then used as an agro fertilizer to re-grow energy crops. The plant will use maize (sweet corn) to fuel the new digesters, planting began in April this year on the 750 Hectare site near Nottingham. The plant  will  comprise

10,000m2 of silage clamps, milling and fermentation followed by digestion with the biogas being used to power the CHP plant. The power generated will be used to supply the adjoining Sewage Works with any surplus being fed into the National Grid network. Stoke Bardolph will become the first large scale CHP Plant in the UK which is powered from maize energy crops.

 The UK's first industrial-scale energy crop anaerobic digestion plant plans to generate 15GWh of electricity each year - the equivalent to enough energy to power more than 4000 homes. This is due to come to fruition in the summer of 2010, when the 2MWe energy crop anaerobic digestion [AD] plant is completed. The scheme is part of Severn Trent Water’s wider strategy for 30% of its company’s power to be from renewable sources by 2013.

GHA Livigunn have been commissioned to provide the following civil engineering design works:

  • Earthworks and ground improvement of excavated material  using dynamic compaction and lime stabilisation. This will reduce both the off site disposal of excavated material and the need to import granular material.
  • 5 No 75m x 25m x5m High Silage Clamps.
  • Anaerobic Digestion Plant. Consisting of Schmack Biogas AG designed fermentation units, digesters, control buildings, 2 No CHP engines, gas handling equipment and storage  facility and sludge cake thickening and storage facilities.
  • Below ground pipe work, pumping mains and pump stations.
  • Road drainage and storm attenuation.
  • New site access bridge linking the plant with the existing sewage works.
  • Site access roads.

GHA Livigunn are members of the Renewable Energy Association.
