Trends and developments of renewable energy projects for electrical energy production in Croatia with emphasis on wind and solar energy

European Union directives, as well as the current legislation of the Republic of Croatia encourage the use of renewable energy sources. To make this increase happen, it is necessary to develop the market, which in Croatia, as well as other EU countries started to develop more intensively after the introduction of legislative framework for the production of electricity from renewable sources. The adoption of Update/upgrade of the Energy Strategy of the Republic of Croatia set even more ambitious goals of using energy from renewable sources. There is notable development on wind energy market since commission of first wind farm Ravne I on island of Pag in 2005. Current cumulative installed power of wind plants in Croatia is 69.75 MW. According to data from the Ministry of Economy, Labour and Entrepreneurship, there is a large number of ongoing projects: 119 projects with total power of 4893 MW has achieved Preliminary energy approval, while 10 projects with total power of 221.7 MW has achieved Energy approval. This paper will give detailed overview and analysis of wind projects according to various criteria (location, installed capacities, involved companies, market shares etc…). Solar energy represents the energy resource that is not yet fully used, although Croatia, especially the coastal part, has a good potential of solar irradiation. Besides the installation of individual solar thermal collectors and small photovoltaic plants on roofs of residential houses, only a few projects using solar energy to support the heating/water heating has been realized and no larger photovoltaic plant has been realized. Few larger photovoltaic plants are in early development phase. This paper will give overview of current commissioned projects, as well as overview of possible future projects regarding use of solar energy in photovoltaic systems. Although the legislative framework and administrative procedures for obtaining the status of eligible producer are defined, there are still present procedure bottlenecks. To facilitate and simplify administrative procedures, it is necessary to analyze the identified obstacles, and joint action of all stakeholders to achieve their removal.
