Bayernplan: An Innovative Business Concept for Biogas
Schmidt, M., Schäfer, R., Ortinger, W.
Increasing volatile and not predictable renewable energies, e. g. solar and wind energies, challenge the power supply system. Up to now mainly conventional energy sources fill the residual load, even though bioenergy is qualified to a certain extent for this important job. Due to an increasing demand for residual load, the introduction of a flexible generation of electricity by biogas has to be considered. Since in Bavaria biogas already is an important source of energy, a plan is discussed, which brings biogaspower plants to a flexible operation and ensures an efficient combination with other renewable energies. In a first step a part of the existing biogaspower plants is shifted towards a flexible operation (repowering). If those plans are pooled, they will operate as a virtual power plant. A calculation shows that the repowering of existing biogaspower plants is a costefficient way to fill the required residual load. Furthermore, the contribution to stabilize the power supply system can be expanded, if repowered biogas motors can be fired in addition to biogas with fossil natural gas or biofuels (second step). If costs for the production of biogas out of manure decline, the available potentials can be tapped (third step).
