Analiza i planiranje naprednog energetskog sustava otoka Šolte
By adopting the “European Green Deal”, the European Union has decided to make Europe the first climate-neutral continent by 2050. In order to reach this goal, it is necessary to implement new measures of increasing energy efficiency as well as integrate production form variable renewable energy sources.
Due to their isolation and, from an energetic standpoint, favourable geographical position, islands make an ideal testing grounds for testing the integration of new technologies into energy systems. The benefit to the islands themselves is twofold – they receive clean, cheap and secure energy, but also a socio-economic development is achieved. The potential of the islands has also been recognized by the EU with the establishment of “The Clean Energy for EU Islands Secretariat”, which helps islands with their energy transition.
Within the framework of this paper an example of the island of Solta is analysed. Foremost, based on the data provided by the energy supplier, an analysis of the current energy consumption on the island was conducted. The current state of the transport sector was also analysed. Using meteorological data, an assessment of the production from RES is given.
Afterwards, using the computer tool EnergyPLAN, a simulation of the energy transition with the final year of 2035. was conducted. Four scenarios were created: implementation of smart lightning, electrification of road traffic, switching of maritime traffic to LNG propulsion, integration of electricity production from PV modules and a final, common scenario. 
The simulated scenarios were compared according to the most important parameters: CO₂ emissions, cost of the energy system, CEEP, required import of electricity and the share of RES in the primary energy consumption.
The comparison concluded that the best results are given by the integration of the energy production from the PV modules and electrification of road traffic, so these measures are proposed as the pillars of the future energy transition of the island of Solta.
