CREATING BRIGHT FUTURE
Termoelektrarna Šoštanj is a limited company, with Holding Slovenske elektrarne as the sole member. The Company is under the management of the General Manager and the Managing Director.
The Company’s principal activity is generation of electricity and thermal energy for district heating.
With an installed power of 1029 MW, the Šoštanj Thermal Power Plant generates, on average, one third of the energy in the country, and in periods of crisis, it can cover more than one half of the national demand. The average annual electricity production ranges from 3,500 and 3,800 GWh. The average annual production of thermal energy used for district heating in the Šaleška Valley amounts to 300-350 GWh. To achieve the above-mentioned annual production of electricity and thermal energy, the power plant uses between 3.5 and 3.8 million tons of coal.
The results of operational readiness of our generators can be compared to higher-ranked European thermal power plants.
SIGNIFICANCE OF TEŠ FOR SLOVENIA
In the HSE Group, TEŠ:
- on average produces 1/3 of electricity in Slovenia, while at the same time offering a wide range of system services (primary, secondary, and tertiary reserve),
- by means of cogeneration, we produce approx. 350 GWh of thermal energy for heating purposes in the valley, thus contributing to cleaner air.
HISTORY
The decision to build the Šoštanj Thermal Power Plant was made in 1946, as a result of a great need for electricity and large coal deposits in the Šalek valley.
The construction started in 1947 and was continued, due to certain complications, five years later. In 1956, the construction of two 30 MW units was completed. In 1960, the 75 MW Unit 3 was built and in 1973, the 275 MV Unit 4 started to generate electricity.
Due to rapid deterioration of energy position of Slovenia and an increasing significance of coal as energy fuel, a call for tender for the construction of a new 345 MW unit was conducted already in 1973, with participation of all significant global manufacturers of thermal power generation facilities. The foundation stone was laid on 01 February 1975, followed immediately by the beginning of construction works. The majority of equipment was installed in 1976; the installation was completed in the following year when all necessary operation test were conducted. The first synchronisation of the unit was carried out on 25 September 1977 and regular operation of the unit began on 27 January 1978. With the total installed capacity increasing to 755 MW, TEŠ now represents the largest power generation plant in Slovenia. The construction itself was accompanied by the installation of the most advanced equipment in Europe. Two gas units, each with nominal power of 42 MW, started operating in 2008. In the same year, Unit 2 was permanently shut down, followed by the shutdown of Unit 1 in 2010.
The decision about the construction of the 600 MW Unit 6 was made in 2004; from the environmental point of view, it represented continuation of the ecological rehabilitation which we started implementing – with a great concern for the environment – already in 1983. The purpose of Unit 6 is a gradual replacement of technologically obsolete and economically unprofitable Units 1, 2, 3, and 4. To generate the same amount of energy, Unit 6 uses approximately 30 percent less coal, resulting in significantly lower total emissions to the environment; while generating the same amount of energy, its CO2 emissions are 30 percent lower as those from other units at TEŠ. With the construction of Unit 6, which started trial operation in June 2015, we reduced the level of environmental pollution, improved the quality and energy efficiency, and provided an opportunity for the power plant to achieve compliance with international standards on best available technology.
