  • Electricity Markets During the Liberalization: the Case of a European Union Country
    energies Article Electricity Markets during the Liberalization: The Case of a European Union Country Štefan Bojnec * and Alan Križaj Faculty of Management, University of Primorska, Izolska vrata 2, SI-6101 Koper-Capodistria, Slovenia; [email protected] * Correspondence: [email protected] or [email protected] Abstract: This paper analyzes electricity markets in Slovenia during the specific period of market deregulation and price liberalization. The drivers of electricity prices and electricity consumption are investigated. The Slovenian electricity markets are analyzed in relation with the European Energy Exchange (EEX) market. Associations between electricity prices on the one hand, and primary energy prices, variation in air temperature, daily maximum electricity power, and cross-border grid prices on the other hand, are analyzed separately for industrial and household consumers. Monthly data are used in a regression analysis during the period of Slovenia’s electricity market deregulation and price liberalization. Empirical results show that electricity prices achieved in the EEX market were significantly associated with primary energy prices. In Slovenia, the prices for daily maximum electricity power were significantly associated with electricity prices achieved on the EEX market. The increases in electricity prices for households, however, cannot be explained with developments in electricity prices on the EEX market. As the period analyzed is the stage of market deregulation and price liberalization, this can have important policy implications for the countries that still have regulated and monopolized electricity markets. Opening the electricity markets is expected to increase competition and reduce pressures for electricity price increases. However, the experiences Citation: Bojnec, Š.; Križaj, A.

Key information about renewable energy in Slovenia Slovenia’s share of installed renewable capacity amounts to almost 10 percent of the total installed electricity capacity. However, the technical potential – particularly for solar power – if fully exploited would be more than five times as much than the current total installed capacity. To increase its share in renewable energy electricity production, the Government of Slovenia promotes electricity generated from renewable sources with a feed-in tariff. Eligible is electricity produced from wind, solar, geothermal, biogas, biomass and hydropower plants. The maximum eligibility period for the feed-in tariff is 15 years and it applies only

  • Renewable Sources of Energy: Hydro-Electricity in Slovenia
    Š. Bojnec, D. Papler Obnovljivi izvori energije: hidro električna energija u Sloveniji ISSN 1330-3651 UDC/UDK 620.92:621.311.21(497.4) RENEWABLE SOURCES OF ENERGY: HYDRO-ELECTRICITY IN SLOVENIA Štefan Bojnec, Drago Papler Original scientific paper Electricity supply in Slovenia is largely dependent on traditional non-renewable sources of electrical energy. In spite of some efforts made to change the sources of electrical energy, not significant shifts from traditional non-renewable fossil sources of electrical energy to renewable sources of electrical energy are found. Electricity supply from water resources is dependent on natural conditions, but it is particularly biased on the adverse weather conditions. The changing weather conditions between raining and sunshine periods are a reason for the needs to diversify supply of electrical energy from hydro renewable sources of energy to a combination with solar energy and co-production of energy from biomass and other renewable sources of energy. There is a need for changes in green electrical energy supply not only towards hydro resources, but particularly towards other renewable sources of electrical energy such as solar, biomass, thermal water, wind and biogas energy.

In addition, there is also a uranium mine and mill in the decommissioning stage at Žirovski vrh. The geographical locations of the nuclear and radiation facilities are given in the figure below. The Republic of Slovenia has no facility for final disposal of radioactive waste or spent nuclear fuel, however the site for LILW repository has been approved.

  • Public Acceptance, a Key Issue of Nuclear Energy
    mm « rt m? ^.^ m^ rf^^^ ' If III 11111 Illll l|| International Conference HR9800017 Nuclear Option in Countries with Small and Med, Opatija, Croatia, 1996 Public Acceptance, a Key Issue of Nuclear Energy Andrej Stritar Nuclear Training Centre Jozef Stefan Institute Jamova 39, 1001 Ljubljana Slovenia Abstract A brief history of public acceptance of nuclear energy in Slovenia is given. While informer Yugoslavia a problem of public acceptance virtually did not exist because of undemocratic social system, it grew larger and larger with the process of democratization in late eighties. The first democratic government in Slovenia had to abandon its original idea for an early closure of the nuclear power plant Krsko. In 1995 and 1996 there were two attempts to organize the national referendum about the future of the plant. The lessons learned from the public debates in recent years could help other countries entering the nuclear program to prepare and implement efficient public information strategy. Introduction Nuclear Energy is today faced with a strong opposition in practically all 30 countries with nuclear power plants around the world. International environmental groups are performing additional pressure. This fear from nuclear is so strong, that the expansion of nuclear energy is almost completely halted in the western world. It is very difficult to find a simple reason for such a resistance to nuclear technology and to remove it by suitable actions. For the democratic country like Croatia, which intends to construct the first nuclear power plant on its territory, this could be the hardest problem. While all the technological problems could be successfully resolved on the level of technical professionals, the problem of public acceptance requires a complex management in the area of sociological sciences.
