This work has been carried out as part of the ETI’s wider Macro Distributed Energy (DE) research project to understand the economics and therefore the opportunities for DE across the UK. Understanding the capital cost (CAPEX) of District Heating Networks (DHN) is an important part of that process as the networks typically represent 60% of the capital cost of a scheme. The work combines a statistical approach with detailed design modelling tools incorporating GIS mapping data and cost data from recent UK DHN projects. The economic case for Macro-DE in Great Britain (GB) is being assessed by carrying out detailed economic and energy modelling for 20 Characteristic Zones. The results from these zones will then be extrapolated to GB as a whole.
The purpose of this report is to document the resultsobtained from District Heating Network (DHN) modelling of a sample comprisingof three Characteristic Zones (CZs) containing 16 Middle Layer Super Output Areas (MLSOAs) in total. The purpose of carrying out DHN modelling inthe Macro DE project is to verify the proposed Macro DE Cost Algorithm and determine any unknown factors to be able to confidently extrapolate results for the remaining characteristic zoneswhich will not be individually modelled.The costs calculated for each CZ will then be used to establish the GB benefits case for DHNs. An additional benefit of the DHN modelling is the associated calculations of heat loss and required pumping energy which also has been included in the analysis.
