Promising areas for the construction of a heat network - various variants (2012)

The 'Warmtekaart Vlaanderen' was commissioned by the Flemish Energy Agency to implement EU Directive 2012/27/EU on energy efficiency. The main products are maps with heat demand and heat supply for the current situation (2012) and a map with promising areas for heat recovery and heat networks in the future, both for the territory of Flanders. The study was carried out by VITO in collaboration with the distribution system operators Eandis and Infrax. You can consult the accompanying report here: www.energiesparen.be/ Warmtekaart. -- In the context of the Heat Map of Flanders, it was investigated for each grid cell of 1200 x 1200m in Flanders whether it is a promising (economically interesting or benefits greater than the costs) area for investment in a heat network based on residual heat or on the basis of heat from a new high-efficiency cogeneration plant. For more background information, please refer to the report. -- This section contains four map layers: Title (1): Using residual heat in the same grid cell. Map layer name (1): er_kb_net_lok_1200m Description (1): In this cost-benefit analysis, the economic potential for a local heat network was investigated within each grid cell with available residual heat. The calculations take into account support mechanisms from the Flemish government ("Residual heat investment support"). The analysis takes place at a resolution of 1200 x 1200 m and is based on the situation in 2012. Title (2) : If the residual heat is transported to neighboring cells. Map layer name (2): er_kb_net_nab_1200m Description (2): For each grid cell with a heat demand, a cost-benefit calculation is made based on available residual heat in neighboring grid cells, the so-called grid cell with a “heat source”. The transport of the residual heat to the grid cell under consideration entails additional costs. This is based on a direct supply to the grid cell under evaluation. The calculations take into account support mechanisms from the Flemish government ("Residual heat investment support"). The analysis takes place at a resolution of 1200 x 1200 m and is based on the situation in 2012. Title (3): Where the residual heat is extracted from a neighboring cell, with a residual heat value of 25 EUR/MWh. Map layer name (3): er_kb_net_comb_max_wrw_1200m Description (3): A cost-benefit calculation is made for each grid cell with a heat demand, which is based on available residual heat in neighboring grid cells, the so-called grid cell with a “heat source”. The transport of the residual heat to the grid cell under consideration entails additional costs. This time possible economies of scale are taken into account if intermediate grid cells themselves proceed to the construction of a heat network. The calculations take into account support mechanisms from the Flemish government ("Residual heat investment support"). This is a variant of the map 'Promising areas for the construction of a heat network in which the residual heat is not obtained directly from the source, but via a neighboring cell, with a value for residual heat of 0 EUR/MWh.'. The analysis takes place at a resolution of 1200 x 1200 m and is based on the situation in 2012. Title (4) : With CHP as heat source, scenario low fuel prices. Map layer name (4): er_kb_net_wkk_min_bp_1200m Description (4): For each grid cell, a cost-benefit calculation is made for the installation of a new central CHP (gas turbine) that delivers its heat within the same grid cell using a heat network. The CHP certificates are taken into account in the calculations. In this scenario, fuel prices are reduced. The effect on benefits can be compared with the map 'With CHP as heat source'. The analysis takes place at a resolution of 1200 x 1200 m and is based on the situation in 2012.
