Community Wüstenrot has set itself the goal of becoming an energy-plus community by the year 2020. In the initial project “EnVisaGe” a roadmap for this purpose had already been developed .


The aim of the follow-up project „EnVisaGe-Plus“ is to increase the regional use of the regional energy network with the city of Schwäbisch Hall and its municipal utilities. This is going to be achieved by the implementation of two projects. One is a plus energy settlement with a large scale geothermal heat supply and SmartGrid components. The other one is a Biomass heating settlement with solar heat support. Both heat district networks which were realized within the framework of “EnVisaGe” realize the first steps toward an energy plus community.


The first objective of the follow-up project „EnVisaGe-Plus“ is to analyse and optimize the efficiency of the different technologies and control strategies through intensive monitoring of the implementation projects “EnVisaGe” (Wüstenrot) and “+Eins” (Landshut). A comparative study analyses and compares the energy and economic efficiency of the heat supply concepts implemented in both projects.


The second objective is to transfer the concept of the “local energy transition” to the region via the regional energy exchange of energy cells. Local energy surpluses are predicted and identified and regionally appropriate sinks for the surpluses are also identified.


The third objective is the development of new concepts for regenerative operated heat networks for the heat supply in rural areas and exemplified in the community of Wüstenrot. The aim is to develop economical solutions through innovative technical approaches together with investment, participation and operator models which can also be applied to other rural communities to rapidly increase the part of renewable energy sources of heat supply. Central technical research topics are the reduction of heat losses, the integration of decentralized renewable heat sources (solar thermal energy, waste heat, geothermal energy, etc.) and the sector coupling to the electricity grid through power-to-heat.


Goals:

  • Continuing and evaluation by monitoring of the implementation projects of „EnVisaGe“ (Wüstenrot) and „+Eins“ (Landshut)
  • The concept of the “local energy transition” through the regional energy exchange of energy cells should be transferred to the region
  • New concepts for renewable heating networks for heat supply in rural areas should be developed and implemented exemplarily in Wüstenrot
