Integration of geothermal power plants into the Croatian energy system

Hrvatski energetski sustav značajno je ovisan o uvozu energije. Ulaskom u Europsku uniju ima obvezu implementacije obnovljivih izvora energije kao i smanjenja emisija stakleničkih plinova. Svrha rada je analizirati četiri scenarija ponašanja energetskog sustava Republike Hrvatske pri instaliranju geotermalnih elektrana. Svaki od scenarija analiziran je kroz potrošnju primarnih izvora energije, udio obnovljivih izvora energije u potrošnji električne energije te emisije CO2 u odnosu na bazni scenarij za 2020. godinu. Proračuni scenarija provedeni su u programu EnergyPLAN, te analizirani pomoću programa Excel. Napravljen je proračun niveliranog troška proizvodnje energije na primjeru projekta geotermalne elektrane. Zatim je provedena analiza osjetljivosti na promjenu ulaznih parametara.Croatian energy system is heavily dependent on energy imports, and by joining the European Union has taken an obligation to implement renewable energy resources as well as to reduce greenhouse gas emissions. The purpose of this paper is to analyze the behavior of energy system of the Republic of Croatia when installing geothermal power plants. This paper analyzes four scenarios that integrate the geothermal power plants through the analysis of primary energy supply, share of renewable energy sources in final electricity consumption, and CO2 emissions regarding the base scenario for the year 2020. Scenarios are carried out in the EnergyPLAN program and analyzed in Excel. Levelized cost of energy analysis was made on the example of a geothermal power plant project. Finally, the sensitivity analysis was carried out for each of the input parameters
