Slovakia — Energy Infrastructure

OverWatts maps 35 energy assets in Slovakia across 8 layers — the 103rd-largest mapped base of 157 countries. They include 15 power plants, 7 pipelines and 4 cement plants. Operating generation capacity is 5.3 GW, led by nuclear at 47%. Refining capacity is about 124 kb/d.

The companies named on the most assets are Enel SpA (6), EP Slovakia BV (6) and eustream (6), counting both ownership and operatorship. Half of Slovakia's mapped assets in service predate 1982 (median commissioning year of the 16 with a known date) and the oldest still listed is U. S. Steel Košice steel plant, dating from 1965. 2 projects are under construction or proposed, led by Bohunice nuclear power plant (1.2 GW).
