Potential areas for the construction of a heat network — various variants (2012)

The ‘Warmtekaart Vlaanderen’ was commissioned by the Flemish Energy Agency to implement the EU Directive 2012/27/EU on energy efficiency. The main products are maps of 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 cooperation with the distribution system operators Eandis and Infrax. You can consult the accompanying report here: www.energiesparen.be/warmtekaart — In the context of the Flanders heat map, for each grid cell of 1200 x 1 200 m in Flanders, it was examined whether it is a promising area (economically interesting or benefits greater than the costs) for the investment in a heat network based on residual heat or on the basis of heat from a new high-efficiency cogeneration. For more background information, please refer to the report. — This section contains four layers of map: Title (1): Using residual heat in the same grid cell. Card layer name (1):er_kb_net_lok_1200 m Description (1): In this cost benefit analysis, the economic potential for a local heat network was examined within each grid cell with available residual heat. The calculations take into account aid mechanisms from the Flemish Government (‘Investment aid residual heat’). The analysis is based on a resolution of 1200 x 1 200 m and is based on the situation in 2012. Title (2): If the residual heat is transported to neighbouring cells. Card layer name (2):er_kb_net_nab_1200 m Description (2): For each grid cell with a heat demand, a cost benefit calculation is made based on available residual heat in neighbouring grid cells, the so-called “heat source” grid cell. Taking into account the transport of the residual heat to the grid cell entails additional costs. This is based on a direct delivery to the grid cell under evaluation. The calculations take into account aid mechanisms from the Flemish Government (‘Investment aid residual heat’). The analysis is based on a resolution of 1200 x 1 200 m and is based on the situation in 2012. Title (3): Where the residual heat is extracted from a neighbouring cell, with a residual heat value of EUR 25/MWh. Card layer name (3):er_kb_net_comb_max_wrw_1200 m Description (3): For each grid cell with a heat demand, a cost benefit calculation is made based on available residual heat in neighbouring grid cells, the so-called “heat source” grid cell. Taking into account the transport of the residual heat to the grid cell entails additional costs. This time, potential economies of scale will be taken into account if intermediate grid cells themselves proceed to the construction of a heat network. The calculations take into account aid mechanisms from the Flemish Government (‘Investment aid residual heat’). This is a variant on the map ‘Candy areas for the construction of a heat network where the residual heat is not directly taken from the source but via a neighbouring cell, with a residual heat value of EUR 0/MWh.’ The analysis is based on a resolution of 1200 x 1 200 m and is based on the situation in 2012. Title (4): With CHP as a heat source, low fuel prices scenario. Card layer name (4):er_kb_net_wkk_min_bp_1200 m Description (4): For each grid cell, a cost benefit calculation is made for installing a new central CHP (gas turbine) that delivers its heat within the same grid cell using a heat grid. In the calculations, CHP certificates are charged. In this scenario, fuel prices will be reduced. The effect on benefits can be compared to the map ‘With CHP as a heat source’. The analysis is based on a resolution of 1200 x 1 200 m and is based on the situation in 2012.
