The work is developed in Centre for Geodesy and Geoinformatics, HFT Stuttgart for project EnSys-LE. The research project serves to advance the state of the art in the field of local energy markets and their linkage to supra-regional markets. A key result will be, for example, the extent to which local renewable energy sources are over- or under-invested in relation to national targets. It is founded by the German Federal Ministry for Economic Affairs and Climate Action (BMWi) under grant agreement No 03ET4061B.
