Slovenia — Energy Infrastructure

OverWatts maps 28 energy assets in Slovenia across 7 layers — the 115th-largest mapped base of 157 countries. They include 13 power plants, 8 pipelines and 2 grid storages. Operating generation capacity is 2.7 GW, led by coal at 46%.

The companies named on the most assets are Plinovodi doo (8), Dravske Elektrarne Maribor (DEM) (4) and GEN energija doo (2), counting both ownership and operatorship. Half of Slovenia's mapped assets in service predate 1978 (median commissioning year of the 10 with a known date) and the oldest still listed is Deskle Cement Plant, dating from 1921. 8 projects are under construction or proposed, led by Krško nuclear power plant (1.1 GW).

Operating generation capacity by fuel

Utility-scale sites of 100 MW and above. Distributed generation — rooftop solar especially — is outside the tracker, so this runs below national installed capacity.
