This calculation module uses the European heat density map (EHDM) and a European gross floor area map (EGFAM), both of which were developed in course of the Hotmaps project, to propose a GIS-based method for determining potential DH areas with specific focus on district heating (DH) grid costs. The DH areas are determined via performing sensitivity analyses on the EHDM under consideration of predefined upper bound of the average distribution costs. The approach additionally allows for estimation of length and diameter of transmission lines and their associated costs. The outputs are GIS layers that illustrate areas that are economically viable for construction of DH as well as the cost-minimal transmission lines connecting these regions to each other. The calculation module can be used to study the impact of parameters like grid costs ceiling and market share on potential and on expansion and extension of the DH systems.
Here, a brief explanation of methodology is provided. For a more complete explanation of the methodology and formulations, please to the paper published about this calculation module [1].
The aim of the calculation module is to find regions in which DH system can be built without exceeding a user-defined average specific cost ceiling in EUR/MWh. This is done under following assumptions:
The determination of economic DH areas is done in three steps.
STEP 1: Calculation of distribution grid costs based on heat demand and plot ratio using EHDM and EGFAM
STEP 2: Determination of potential DH areas
STEP 3: Determination of economic DH areas and transmission line capacities and configuration required to connect these areas to each other.
Here you get the bleeding-edge development for this calculation module.
