Abstract The Russian invasion of Ukraine that started on 24 February 2022 has had a dramatic impact on the energy policy of the European Union and its member states. Nonetheless, not all EU members have radically overhauled their energy sectors and policies. Looking at the period between February 2022 and December 2023, this paper argues that Slovakia’s energy sector has remained unchanged in comparison to developments within the EU and beyond. Slovakia has continued to purchase natural gas from Russia, having negotiated an exemption from the EU sanctions on Russian oil, and gas consumption decreased only minimally in the winter of 2022/2023. Furthermore, it maintained at best a lukewarm position on renewable energy sources and even struggled to implement those energy efficiency measures that were included in the post-pandemic recovery plans. Slovakia also did not reconsider its coal phase-out deadline of 2023 and its (already very supportive) nuclear policy. We explain this policy persistence with the help of a revised lock-in concept which, in the case of Slovakia, is mostly connected to nuclear energy (ʻnuclear lock-in’), which locks out alternative energy sources, especially renewables.
