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).

 Scope:

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.

Services:

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

Solution:

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.
