The ambition to cover the current energy demand by using renewable energy sources has led to a strong expansion of renewable electricity generation across Europe. This process was accelerated by appropriate support, as well as in Burgenland, which today is characterized by a high share of wind energy. The situation of the high share of volatile renewable generation results in new challenges for the energy system. The project "Windvermarktung" exactly addresses these challenges. In the named region, business models and application areas for wind power generation are meant to be developed with the help of system flexibilities (battery storage systems, demand side management, power to heat and power to cold and biomass). The development of new business models is expected to result in an improvement in the profitability of wind power plants after a suspension of the subsidy, which is the central task of this thesis. Thus, the aim of the whole project is the preparation for the creation of a region, which stands for a sensible handling of the resource wind energy. The analysis of the results show that not all system flexibilities are adequate for applying them to merchandise wind energy in Burgenland. Combinations with demand side management and/or power to heat are obtained effective and economically profitable and can therefore be integrated into an overall, future-oriented concept.
