Across the 8 Slovakia power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 8.0 Mt CO₂/yr. The single largest emitter, U.S. Steel Kosice Works power station (coal), accounts for about 67% of that 8-plant reported subset (not of the whole country). The top three owners — US Steel Košice sro [100%], Slovenské Elektrárne AŞ [100%], Slovnaft AS [100%] — control roughly 90% of that 8-plant reported subset. Most of these plants sit in a continental Köppen climate zone.

There are 37 power plants in Slovakia in this open dataset, with about 7,678 MW of total capacity.
Trebisov power station is the largest at about 885 MW (coal).
The most common plant type in this dataset is hydro (21 plants), across 5 fuel types in total.
Slovakia's grid carbon intensity is about 95 gCO₂/kWh, with 85.2% low-carbon generation (<a href="https://ember-energy.org/" rel="nofollow">Ember</a> / <a href="https://ourworldindata.org/energy" rel="nofollow">Our World in Data</a> (CC BY 4.0)).
