“…Feldheim is already a self-sufficient region in Germany [1] while various other areas plan to be fully independent in the electricity sector in the upcoming years (Wildpoldsried [2], Alheim [3], Wunsiedel [4]). Although it is strongly controversial that the autarky is the future in the climate change it is considered challenging and environmentally positive at the same time to develop a relatively or exclusively local sustainability where no energy sources ought to be imported [5].…”

The autarchic communities are an attractive scenario that more and more local actors strive to achieve. In electricity autonomous cases a battery system stands as prerequisite to succeed renewables time shifting due to the intermittent nature of decentralized generation. In the present study the local autarky in the electricity sector is examined for a system composed of a photovoltaic installation, a wind farm, a biogas combined heat power plant and a battery. The selected storage system is a Lithium Ion battery and two different modelling alternatives have been applied. Consequently, the two system versions have been tested for three autonomous case study regions in north, central and south Germany. The system is subsequently operated, and the minimum battery capacity is estimated for each case study based on dynamic simulations. Simulation results indicate that the autarky in the electricity sector can be feasible, but the capacity is underestimated almost up to 30%, if the aging effect of the battery is neglected and the efficiency grade is considered steady. Moreover, outcomes show that the calculated battery capacity is higher for the south city due to the solar power variability as an outcome of the seasonal variation.
