Sažetak

Investment in the facility for harnessing a stream of water is usually
characterized by long payback period. Hence investment choice not only needs to
be optimal, but it also needs to be robust enough to cope with uncertainties which
occur during payback period. In this research, a family of flow duration curves is
created to model stochastic nature of water availability. The risk-constrained
approach for assessment of investments in cascaded hydropower plants is proposed
in a form of a mixed-integer linear programming. Proposed approach will manage a
risk of large financial losses induced by these uncertainties. The project of run-ofriver
power plants on the Sava river stretch (Croatia) from border with Slovenia to
the city of Sisak is analyzed.
