Nuclear power, which currently accounts for more than 50% of Slovakia’s total power generation, will maintain its dominance of the country’s energy generation mix over the next decade, as the country continues to be a net importer of electricity and thermal fuels. Nuclear power is expected to account for 64.9% of the country’s generation mix by 2035.
Demand for energy from the industrial and commercial sectors is currently driving consumption levels. Most of the country’s natural gas demand is met by imports from Russia and so, as a member of the EU, Slovakia will be mindful that EU sanctions related to the Ukraine war will create uncertainty as EU countries hold a united front on reducing its dependency on Russian imports.
Annual electricity consumption in Slovakia increased from 24.9 Terawatt hours (TWh) in 2010 to 26.4TWh in 2021 at a CAGR of 0.5%. Between 2021 and 2030, the increase is expected to be slightly higher due to expected resurgence of the industrial sector. Electricity consumption is expected to touch 28.6TWh by 2030.
Slovakia is a net importer of electricity, with approximately 0.7TWh of electricity in 2021. The country is dependent on imports to meet the majority of its thermal fuel needs. In fact, most of its natural gas demand is met by imports from Russia. Although Slovakia has good potential coal reserves, these are not currently recoverable, making it dependent on imports for more than 90% of its coal resources. Although the government is looking to expand its renewable power capacity, the Slovakian Government will continue to depend on nuclear power generation during the forecast period.
