Sheffield's District Energy Network: A Model for Sustainable Urban Energy Management

On February 17, 2011, Neil Townrow presented Sheffield’s District Energy Network, lauded as the UK's largest and most efficient Energy Recovery Facility (ERF). With adaptation to stringent emissions regulations, the network supports a greener Sheffield—home to 2 million trees, 50 parks, and 150 woodlands. It operates 43 km of thermal networks that generate 60 megawatts of thermal energy, while achieving notable carbon savings against gas systems. The integrated waste contract with Veolia exemplifies a cradle-to-grave approach, ensuring innovation in energy management and environmental stewardship.

  1. District EnergyNetwork in Sheffield Neil Townrow 17th February 2011

  2. Sheffield • Greenest city in the UK! • 5 Rivers • 7 Hills • 2 Million Trees • 50 Parks • 150 Woodlands • Most efficient ERF in the UK • Largest District Energy system in the UK

  3. Integrated Waste Contract Approach • Ageing ERF in Sheffield with poor performance and pending legislation (WID) that ERF emissions would not meet • Landfill Directive targets for every Council, with financial penalties, for non achieving • Pre- PFI deal, industry response was revenue of collection service to off set investment in treatment needed • Cradle to grave approach incorporating all collection, treatment, customer support, education & awareness

  4. Working in Partnershipwith Veolia • Awarded in 2001 for 30 years, extended by 5 years • Transfer of assets from SCC to Veolia vehicles, depot, household waste recycling centres, ERF, district energy network • Refit of ERF to support DE Network and delivery of a new Energy Recovery Facility on same site • New plant commissioned in 2005, handling 225,000 tonnes of waste

  5. old plant

  6. Energy Recovery • History of incinerator plants on edge of Sheffield city centre, back to 1800s • DE network developed from 1970s, at time of energy crisis • 43km of network, 2 networks, supporting social housing & city centre of old, poorly insulated municipal buildings • Generates 60Megawatts of thermal energy plus 19 Megawatts of electrical energy • Electricity sales to grid secured through NFFO

  7. Social Housing Customers • Biggest grade II listed structure in Europe • Within a kilometre of ERF • Social housing • Under redevelopment for mixed use

  8. Other District Energy Customers

  9. Customer Split by Sector

  10. Securing Customers District Energy • Carbon saving of around 20,000 tonnes compared to gas based system • Public sector - long term contracts • Getting private sector to understand the system • Expectation around pricing (usual tie to gas plus RPI) • Planning policy • Carbon Reduction Commitment

  11. District Energy Network Development • Further development to de-carbonise network, moving back up systems from fossil fuels • Customer base moving: Network 1 - 1960s flats pull down & re-gen Network 2 – fewer leaky old buildings • City centre development (recession) • Provision of cooling, Crucible Theatre first scheme
