Renewable Heating for Large-Scale Mixed Developments

Stratford-on-Avon District Council

This renewable heating project was supported and funded by Stratford-upon-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. The proposed network comprised several large strategic sites designated for development, including 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. This was followed by a detailed feasibility study for the proposed renewable heating newtork in the Canal Quarter development in Stratford-upon-Avon town centre – a mixed development, largely consisting of residential.

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:

Two opportunities were identified. 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, also identified as economic, included a small gas CHP and a large high-temperature air source heat pump.
