Electricity market
Structure of power sector
Elektro-Slovenija (ELES)
In 1991, the government created, by decree, the state electricity company Elektro-Slovenija (ELES). Elektro-Slovenija, d.o.o. (ELES) is a transmission company. As a national Operator its primary responsibility has been, for quite a number of years, reliable operation of the Slovenian electric power system and quality consumer supply. The electricity market having been opened, the company's original mission remains to be one of its major concerns also in future. An other important field of activity is the maintenance of the 400, 220 and 110 kV networks and high-voltage electric power facilities. This company of transmission buys electricity from the generation companies. ELES sells electricity to the 5 regional public companies of distribution: Elektro Ljublijana (37% of the sales), Elektro Maribor (20%), Elektro Celje (19%), Elektro Promorska (15%) and Elektro Gorenjska (9%). The distribution companies supply all users except for five large industrial consumers supplied directly by ELES.
Holding Slovenske elektrarne d.o.o.
HSE d.o.o. was established by the government of the Republic of Slovenia in 2001 as an integrated entity of six companies, as follows: the hydropower producers Dravske elektrarne Maribor, Savske elektrarne Ljubljana and Soške elektrarne Nova Gorica, the combined gas-fired power plant TE Brestanica, the coal-fired power plant TE Šoštanj and the Premogovnik Velenje coalmining company. HSE is the largest and leading Slovenian power producer. The Group includes five power production companies, a coalmine, two investment companies and three international companies (HSE Italia, HSE Balkan Energy, HSE Hungary). HSE production companies produce more than 50 percent of all electricity generated in Slovenia.

Status of deregulation
The Slovenian electricity market was officially deregulated as of 15 April 2001, whereby all consumers with installed capacity exceeding 41 kW at a single point of supply or close to two thirds of all consumers were granted the option to select their preferred supplier of electricity.
