Power Plants in Slovenia
Slovenia has 13 power plants mapped on the OverWatts open energy atlas — the 116th-largest fleet of the 155 countries that hold any, and under 0.1% of the world's mapped total. Of these, 7 operating and 4 under construction or proposed. Operating generation capacity totals 2.7 GW across 7 utility-scale plants of 100 MW and above. The largest is Krško nuclear power plant (1.1 GW).
The largest owner-operators are Dravske Elektrarne Maribor (DEM) (3), GEN energija doo (2) and Hrvatska elektroprivreda dd (2) — Dravske Elektrarne Maribor (DEM) alone is named on 23% of them. Half of Slovenia's power plants in service predate 1978 (median commissioning year of the 7 with a known date) and the oldest still listed is Te-Tol power station, dating from 1966. 4 are in the pipeline, led by Krško nuclear power plant (1.1 GW), proposed. They account for 46% of every energy asset OverWatts maps in Slovenia.

Frequently asked
- How many power plants are there in Slovenia?
- OverWatts maps 13 power plants in Slovenia — under 0.1% of the world's mapped total, the 116th-largest national fleet of the 155 countries with any.
- What is the largest power plant in Slovenia?
- Krško nuclear power plant, at 1.1 GW.
- How much power-generation capacity do Slovenia's power plants have?
- About 2.7 GW operating across 7 plants, with a further 2.3 GW under construction or proposed. That covers utility-scale sites of 100 MW and above, so it sits below national installed capacity wherever distributed generation is large.
- Who owns the power plants in Slovenia?
- Dravske Elektrarne Maribor (DEM) is named as owner or operator on the most — 3 of 13 (23%). Next are GEN energija doo (2), Hrvatska elektroprivreda dd (2) and Termoelektrarna Šoštanj doo (2).
- How old are Slovenia's power plants?
- The median commissioning year is 1978, across the 7 in service with a known start date. The oldest still listed is Te-Tol power station (1966).
- What new power plants are being built in Slovenia?
- 4 projects are under construction or proposed. The largest are Krško nuclear power plant (1.1 GW), Kozjak hydroelectric plant (Slovenia) (440 MW) and Družmirje Floating solar farm (140 MW).
