Renewable Heating Options for Large Scale Mixed Developments

Stratford-on-Avon District Council

This project was supported and funded by Stratford-on-Avon District Council and the Heat Networks Delivery Unit (HNDU) of the Department of Business, Energy and Industrial Strategy (BEIS).


We appraised the viability and assessed the risks associated with several renewable district energy network opportunities in the Stratford-upon-Avon area. This comprised of several large strategic sites designated for development that included the Canal Quarter development area and the Long Marsten Airfield Garden Village development.


We were commissioned to undertake heat mapping and masterplanning studies for five areas, followed by a detailed feasibility study for the Canal Quarter mixed (mainly residential) development in Stratford-upon-Avon town centre. This involved:

  • Undertaking an energy demand and supply assessment to identify potential key energy demands and potentially useful heat supplies
  • Identifying viable network and scheme options that considered heat pump and gas CHP technologies
  • Providing recommendations to determine the best approach to deliver priority district energy network opportunities
  • Identifying key stakeholders with a role to play in the delivery of district energy networks
  • Identifying priority areas within strategic sites where district energy schemes may be viable
  • Concept design, route planning and techno-economic modelling


The preferred option consisted of a phased network served by a large canal source heat pump with a self-supply arrangement for electricity from a small gas CHP engine to the heat pump. A potential parallel solution was also identified as economic and this included a small gas CHP and a large high temperature air source heat pump.
