Entwicklungsagentur Region Heide (Germany)

QUARREE100 is an innovative research project with associated implementation that takes on the challenge of establishing an integrated, sustainable energy supply in the heterogeneous existing quarter "Rüsdorfer Kamp" in Heide. The quarter represents a variety of urban structures, which significantly increases the complexity, but also represents a high chance of transferability. On the basis of extensive modelling and research work, an energy concept has been developed that can meet the complex requirements. However, the high investment costs are a challenge for implementation, which are currently difficult to present to potential investors on the basis of classic economic evaluations in comparison with fossil energies. In addition, the high investment costs result in long-term amortisation periods for affordable heat in an energy system in transition, which also leads to further uncertainties on the investment side. The project is also integrated into other strategic processes of the city and the region, which on the one hand also promote urban development and solutions for an integrated energy transition in the region, which then also involves local industry.
