Slovakia has considerable reserves of lignite, but domestic production only covers around 25% of solid fuel consumption. The Slovak Republic is almost 90% dependent on imported primary energy sources. It is therefore subject to a relatively high risk with regard to the security of supply with natural gas, crude oil, coal and nuclear fuel. A quick diversification of the supply would be important from the point of view of the Slovak energy policy in order to achieve a stability of the primary energy supply. Due to the high dependency of Russia on gas imports, the Slovak Republic wants to increase the use of “domestic” resources such as renewable energy sources, but also nuclear energy.
Electricity generation remained relatively stable from 2000 to 2006 at around 32 TWh and only fell to 28 TWh in 2007 - after the planned shutdown of Unit 1 in the Jaslovske Bohunice nuclear power plant. After that, it only changed slightly, until after the shutdown of Unit 2 in the Jaslovske Bohunice nuclear power plant (end of 2008) a further decrease to 26 TWh was recorded in 2009. Overall, electricity generation in the Slovak Republic decreased from 31 TWh to 27 TWh between 2000 and 2018. The use of coal to generate electricity fell by 2 TWh between 2000 and 2018 and was 4 TWh in 2018.
In 2019, nuclear energy contributed the highest (52%) to power generation in the Slovak Republic, followed by hydropower and coal.
