Though the Slovak Republic has significant lignite reserves, domestic production only covers approximately 30% of solid fuel consumption. The country produces limited amounts of crude oil (one refinery in Bratislava with a capacity of 115,000 bbl/d or 5.8 Mt), used in the petrochemical industry, and natural gas; most oil and gas resources are imported from Russia.
In order to increase energy security and reduce dependency, the government is increasingly investing in nuclear energy to cover its energy demand. The majority of Slovakia’s coal resources are imported from nearby Czech Republic. Slovakia has gradually reduced its imports of natural gas since 2010 in order to increase security of supply.
Nuclear power stations continue to generate the highest share of electricity in Slovakia with more than 50% in 2016. Currently, four nuclear reactors (two 471 MW reactors in Jaslovevske Bohunice and two 436 MW reactors in Mochovce) exist with two more (Mochovce 3 and 4) under construction, since the two reactors at Bohunice are expected to close in 2024/2025. At the moment, Slovakia continues to import electricity; it is, however, expected to be self-sufficient after the completion of the two new nuclear reactors in late 2019.
In 2017, nuclear energy contributed the highest (57%) to power generation in the Slovak Republic, followed by hydropower and coal.
