Geographical representations of renewable energy systems

The purpose of this project is to gegraphically map heat demand, heat supply, heat ressources and transmission and distributionfacilities in Denmark.

In the project GIS is used to calculate costs of expansion of district heating. ArcGIS tool is used to delineate DH areas, areas that are sharing a border with DH areas and Individual areas, which are far away from DH areas. Costs of transmission, distribution infrastructure are included. Marginal cost curves for DH expansion are obtained as a result of this calculation. Current and future costs of supplying energy haven't been taken into account in this analysis, but will be included in optimization tool TIMES, which is currently being built at Energy Systems Analysis group, Technical University of Denmark.

As part of the project, potentials for heat savings in Danish building stock. Building stock is divided by time periods, usage types and temperature regions. Calculations are done in 4 steps:

1. Identifying current heat demand including demand for domestic hot water,

2. Calculating effect of heat saving measures (replacing windows, adding insulation to walls, floors, roofs, replacing ventilation systems),

3. Calculating full and marginal costs of heat saving measures,

4. Calculating annualized costs of heat saving measures.

Marginal cost curves of heat saving measures are obtained. These curves will be sent to TIMES model for Denmark and it will use these curves to make optimal choice between savings, DH expansion and investment in supply technologies.
