Slovakia's electricity sector is anchored by the four-reactor Mochovce and Bohunice nuclear complexes, which together delivered ~58% of generation in 2024. The Mochovce-3 unit came online in 2023 and Mochovce-4 in 2024 after decades of construction delays, completing one of Europe's largest nuclear newbuild projects of the 2020s. OKTE, the Slovak day-ahead market operator (alongside SEPS, the national TSO), runs the single SK bidding zone synchronously coupled to Czechia, Hungary, Poland and Ukraine, with day-ahead trading on OKTE.
Hydro from the Váh river adds ~15% of supply and gas-fired CCGTs cover ~12%. Wind has been politically blocked for years and contributes under 1% of generation; solar — long underdeveloped — finally reached 1 GW in 2024 and is targeted to grow to 4 GW by 2030.
The country is a structural exporter to Hungary and Ukraine. Coal generation ended definitively in 2024 with the Nováky plant closure.
