The aim of this work is to highlight challenges, if there are any, in decarbonising national power system in Republic of Slovenia. National electricity grid was hourly simulated using EnergyPlan – Advanced energy system analysis computer model in circumstances where distributed power sources capacity exceeds peak system demand. The goal was to estimate the influence of 4400 MW distributed power production to the power grid with peak demand of up to 3000 MW, respecting the fact that distributed power sources partly meet demand in summer sunlight time, however modestly meets demand in winter time. Electricity demand in summer and winter time are of the same magnitude of order. Modest system capacity for electricity storage were respected and influence to cross border transmission demand was estimated. Chalenges related to grid stability were shown and how nuclear can improve grid stability is presented.
