Comparison of base load - No Nuclear and NPP option
Coal + Import6400 GWh
Nuclear NPP 6800 GWh
Conclusion
Location of Mariovo region has advantages for NPP Good grid connection on 400 kV Hydro nuclear complex of Cebren and Galiste with NPP Reversible HPP is the appropriate solution for the complex Using the storage capacities for hydro energy and NPP cooling
needs Enough water (20 mill m3 /y) for cooling tower of NPP 1000 MW Additional peak energy with reversible HPP Cebren and Galiste
(high tariff of selling) Base load capacity of NPP can be use for pumping regime (low
tariff of buying) Financial benefit with managing the operation of the hydro –
nuclear complex
