Power Plants in Bulgaria
Bulgaria has 49 power plants mapped on the OverWatts open energy atlas — the 60th-largest fleet of the 155 countries that hold any, and 0.2% of the world's mapped total. Of these, 27 operating and 14 under construction or proposed. Operating generation capacity totals 10.2 GW across 27 utility-scale plants of 100 MW and above. The largest is Kozloduy nuclear power plant (2.1 GW).
The largest owner-operators are Natsionalna Elektricheska Kompania (NEK) (10), Sunterra Re (3) and AES Corp (2) — Natsionalna Elektricheska Kompania (NEK) alone is named on 20% of them. Half of Bulgaria's power plants in service predate 1975 (median commissioning year of the 27 with a known date), 7 came online in the past decade and the oldest still listed is Republika power station, dating from 1951. 14 are in the pipeline, led by Kozloduy nuclear power plant (2.0 GW), under construction. They account for 46% of every energy asset OverWatts maps in Bulgaria.

Frequently asked
- How many power plants are there in Bulgaria?
- OverWatts maps 49 power plants in Bulgaria — 0.2% of the world's mapped total, the 60th-largest national fleet of the 155 countries with any.
- What is the largest power plant in Bulgaria?
- Kozloduy nuclear power plant, at 2.1 GW.
- How much power-generation capacity do Bulgaria's power plants have?
- About 10.2 GW operating across 27 plants, with a further 11.2 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 Bulgaria?
- Natsionalna Elektricheska Kompania (NEK) is named as owner or operator on the most — 10 of 49 (20%). Next are Sunterra Re (3), AES Corp (2) and Brikel EAD (2).
- How old are Bulgaria's power plants?
- The median commissioning year is 1975, across the 27 in service with a known start date. The oldest still listed is Republika power station (1951); 7 came online in the past ten years.
- What new power plants are being built in Bulgaria?
- 14 projects are under construction or proposed. The largest are Kozloduy nuclear power plant (2.0 GW), Turnu Magurele - Nikopol hydroelectric plant (840 MW) and Batak Pumped Storage hydroelectric plant (800 MW).
