The objective of this study is to develop a municipal heat supply strategy, which shows a way for the city of Innsbruck to achieve a CO2-neutral heat supply by 2040. Therefore IREES will be analysing the supply potentials for renewable energies and waste heat. In additio the use of energy from waste management as well as the potentials for the expansion of the heating infrastructure will be regarded. On the demand side, the potentials for energy efficiency measures are to be considered and their impact on the solution space for the possible heat supply alternatives. The heat supply plan to be developed should define concrete measures for the city of Innsbruck and show which reduction can be achieved by 2030 as an interim target and how climate neutrality can be achieved by 2040.
