In 2022, a feasibility study was conducted by Grantchester Parish Council with technical support from Scene and Townrock Energy, and funding form the Rural Community Energy Fund (RCEF). The project sought to define how a low carbon heating system could benefit Bildeston residents and businesses through reduced energy bills and carbon emissions.
Ths study found that a heat network for Grantchester would be financially viable with grant support, having the potential to provide carbon emission reductions and being cost competitive with current forms of energy (i.e., oil, LPG, and direct electric heating). The primary heat source recommended was a water-source heat pump, utilising heat from the River Cam to supply local homes and businesses. Scene conducted all elements of the study, including community engagement, landownership review, techno-economic assessment of heat demand and future heating scenarios, and long term financial and impact modelling. Scene was supported by TownRock Energy, who provided thermogeological assessments for the local area.
