Thanks mainly to nuclear power plants, the largest electricity producer in Slovakia supplied up to 94% of carbon dioxide-free electricity to the grid.

Slovenske elektrarne, a.s. produced 0.34 terawatt-hours more electricity in 2021 than in the previous year. The difference was caused by the pandemic. While energy production had to be curtailed in the spring of 2020, according to preliminary data from the state-owned Slovenska elektrizacna a prenosova sustava, a.s. (Slovak Electricity Transmission System, SEPS), consumption in Slovakia grew last year to 30.9 TWh, or by more than 5% year-on-year. Slovakia had to import 0.727 TWh from abroad to cover consumption.

As much as 19.112 TWh, i.e. 64.3% of all electricity generated in Slovakia, came from Slovenske elektrarne. After adjusting for own consumption, the company supplied 17.271 TWh to the grid, which represents approximately 60% of the country's electricity consumption.

In the autumn, the energy market was affected by lower production from renewable sources in Europe and panic over natural gas supplies. It only broke down just before the Christmas holidays. "There was a shortage of electricity in the electricity system and there were frequent activations of support services to equalize the power balance," said Jan Mazanik, Head of Resource Deployment Optimisation at Slovenske elektrarne.

Higher output of nuclear power plants

Thanks to investments in increasing the efficiency of units, the installed capacity of Slovak nuclear power plants exceeded 2,000 megawatts last year, bringing the total capacity of Slovenske elektrarne to 4,143.8 MW. The nuclear power plants generated approximately 2% more electricity compared to 2020.

The year 2021 was average in terms of hydrological conditions. "In the first months of 2021, hydroelectric generation was significantly above plan. Snow stocks melted in regular heat waves, which we were able to use energy efficiently. The highest production from water was during a cold and wet May," says Jan Mazanik. The situation worsened in autumn, which was very poor in terms of rainfall. Slovenske elektrarne used the water reserves in the peaking reservoirs, but despite this, production from water was very low at the end of the year. Due to fluctuations in electricity prices, pumped storage plants were used more intensively.

Coal-fired generation accounted for 6.1% of the net supply to the grid from Slovenske elektrarne (SE).

In 2021, SE delivered up to 94% of CO2-free electricity to the grid - carbon dioxide is considered to be one of the main greenhouse gases causing climate change, and SE expects to achieve record emission-free electricity production after the start-up of Mochovce Unit 3 and the end of production at the Novaky lignite-fired power plants in 2023.

About Slovenske elektrarne

More than 64.3% of all electricity generated in Slovakia comes from Slovenske elektrarne. The electricity they supply to the grid covers around 60% of the country's consumption. In particular, thanks to its nuclear power plants, Slovakia's largest producer supplies up to 94% of its electricity without emitting carbon dioxide, which is considered to be one of the greenhouse gases responsible for global warming. In addition to nuclear power plants, the company also operates 31 hydroelectric, two thermal and two photovoltaic power plants. Their total capacity at the end of 2021 was 4,143.8 megawatts.

Who are the shareholders

The company has two shareholders. The majority shareholder is Slovak Power Holding B.V. (SPH), holding a 66.0000000523% stake in the share capital. In SPH, EP Slovakia B.V. holds a 50 % share in the share capital. (a subsidiary of the EPH group) and the remaining 50 % is held by Enel Produzione S.p.A (a subsidiary of the Enel group). The minority shareholder of Slovenske elektrárne with a 33,9999999477 % share in the share capital is the Slovak Republic, on behalf of which the Ministry of Economy of the Slovak Republic acts.
