The model HIREPS is an optimization model, developed at the Technical University of Vienna by the Energy Economics Group at the Institute of Energy Systems and Electrical Drives. The project has the aim to produce 100 % electricity based on renewable energy sources in Austria and also throughout all Europa using the power generation to obtain the maximum energy from such renewable sources. In this project, the European HIREPS model was supplemented with a model of the Turkish hydropower and analyzes the change of memory management with the increasing renewable energy. The current prices were used by EEX in 2006 and in 2050. Electricity prices in 2050 are a result of the simulation Autres100 research project. Then a planned power station was economically investigated to demystify to what extent the maximum investment is profitable.
