Energy in Slovakia

Primary energy use in Slovakia was 194 TWh and 36 TWh per million inhabitants in 2009.

Energy plan
Slovakia has a plan to get renewable sources of energy up to 19.2% by 2030.

Energy types
From 2024, following the completion of two new nuclear reactors, Slovakia will return to being a net exporter of electricity.

Oil
Slovnaft is the largest oil refinery in Slovakia.

In 2022 Slovakia sought to reduce its reliance on oil from Russia.

Natural gas
Slovenský plynárenský priemysel (Slovak Gas Industry) is the main natural gas supplier in Slovakia.

In 2022 Slovakia sought to reduce its reliance on natural gas from Russia who was supplying 81% in 2020.

Coal
Two coal power stations operate in Slovakia, with one at Nováky, scheduled to close in 2023.

Nuclear Energy
Five operating reactors in two power plants Bohunice Nuclear Power Plant with two reactors dating from the 1980s and three at Mochovce Nuclear Power Plant), with two from the 1990s and the 3rd being commissioned in January 2023. Total electricity generation from nuclear in 2020 was 15.4 TWh. One additional reactor is near completion at Mochovce.

Renewable energy


Renewable energy includes wind, solar, biomass and geothermal energy sources.

Wind power
In the end of 2022 wind power capacity in Slovakia 3MW which has not changed since 2010. In the National Energy and Climate Plan the Government plans to build 500MW of wind by 2030.

Solar power
In 2019 Slovakia had 472 MW of installed solar power capacity. It is expected to rise to 750 MW by 2030.

Biomass
Biomass provides around 4% of electricity generation capacity.

Hydro power
There is hydropower potential in Vah and Orava rivers (before Stary Hrad, and after Kralovianski Meander, Oravka tunnel), with power plants over 30MW as extremely profitable (for low cost/installed MW).

Climate change
Emissions of carbon dioxide in total, per capita in 2007 were 6.8 tons CO2 compared to EU 27 average 7.9 tons. Emission change 2007/1990 (%) was -35.1%. In Europe in 2007 the Slovak emissions of carbon dioxide per capita (6.8 tons CO2) were higher than in Hungary 5.4, Sweden 5.1, Portugal 5.2 or Switzerland 5.6 and lower than in Czech Republic 11.8, Luxembourg 22.4, Finland 12.2, Netherlands 11.1, Germany 9.7 or Ireland 10.1

1990 emissions were 74 Mt eq. The Kyoto protocol target is reduction of 6 Mt (-8%).
