This paper addresses the performance issues of autonomous power systems under high
renewable energy sources (RES) penetration. Renewable energy sources could be the main option
for isolated power generation at remote locations in case that energy storage introduced. At the
moment, pumped hydro storage (PHS) units and batteries storage systems (BSS) represent the
most mature technologies for large scale energy storage. The basic criteria for this kind of energy
storage unit installations include, (a) the existence of an autonomous power system with local
power stations, (b) the high electricity production cost, (c) the potential of renewable energy
sources (mainly wind and solar), and (d) the non-flat terrain morphology (for PHS). Greek islands
represent ideal cases for large scale energy storage installations, as they fulfil all the above
criteria. This paper shows the effect of the installation of a planned PHS unit in Crete island. The
calculations are based on real data provided by the Cretan power system operator, whereas the
results show the effect of energy storage units operation on the energy mix, as well as the
economic viability of the project, which is combined with significant environmental benefits.
