The purpose of this Masterthesis is to provide up to date information as a marketing tool and a basis for decision making for the Hans Künz Company in its business segment of hydraulic steel structure production. The South Eastern Europe (SEE) region and especially the successor states of Yugoslavia and Albania deserve more and more of our attention due its ongoing integration into the European Union. Albania was long isolated from the rest of the European countries being under communist power. Bosnia Herzegovina, Macedonia and Serbia were a part of Socialist Yugoslavia for almost 60 years. All these countries are now on their own way towards free market economy and the participation in the European Union. In this Masterthesis the current energy situation with a focus especially on hydropower in these countries will be evaluated. Decisive factors are the share of hydropower in total electricity production and the technically and economically feasible hydropower potential in these countries. Further on the framework conditions for building new hydropower stations will be taken into account. The last important factor for Künz is the market presence of European and especially Austrian companies in the single markets.
