"Electricity production through wind power in the Burgenland will reach record highs in 2013 and for the first time, will exceed the energy demands of the Federal State. As a result of the planned further expansion of renewable energy capacities, high levels of fluctuating electrical energy will be fed into the grid in the future. By 2020, a capacity of over 2,000 MW will be installed. The aim of this paper is to calculate and analyse both the current excess energy levels and those expected for the future in order to define possible storage potential for this energy. Data provided by the Netz Burgenland GmbH serves as the basis for calculating storage potential. The prognosis calculation for load development takes into account the respective changes observed in the past. Modelling of generation capacities is based on a standardisation of the current profile. In conclusion, these standardised values will be used to calculate a forecast for the 2020 scenario for renewable energy based on the planned expansion of the current resources. When analysing storage potential, it can be seen that there is a significant dependence on wind power for the generation portfolio. Currently, storage plants are only required for excess energy generated through wind power on days with strong wind conditions. The total excess energy generated in 2012 was approx. 190,000 MWh. The maximum loading and unloading capacities were 300 MW. As a result of the planned further expansion of wind power, annual electricity generation will increase 3.5-fold by 2020. Large-scale implantation of storage reservoirs could serve to order to avoid bottlenecks in the electricity grid. The calculations in this paper have predicted a storage potential for the annual storage reservoir of around 2.5 GWh with a maximum loading capacity of up to 1,500 MW for 2020. The excess energy generated will be in the region of 2.8 GWh and more energy will be generated each month than required. The storage of excess energy will significantly improve the future marketability of renewable energy and give further market credibility to this technology. A cooperation between renewable energy generation technologies and energy storage could present a significant alternative to risk sharing in power plant portfolios."
