Bulgaria has one of the lowest wholesale electricity prices in the EU, anchored by the 2 000 MW Kozloduy nuclear plant which alone covers 35–40% of national generation. Coal from the Maritsa basin still provides another 35% — making Bulgaria one of the EU's most coal-dependent grids alongside Poland.
Hydro and wind round out the mix at ~10% each, with solar growing fast (over 4 GW installed by end-2025). Electricity System Operator (ESO) runs the single BG bidding zone and operates IBEX, the day-ahead market. Bulgaria is a regional power exporter, sending roughly 6 TWh annually to Greece, Romania, Serbia and North Macedonia.
Plans to retire the lignite plants by 2038 are being met with strong pushback from coal regions; the government's energy strategy bets on extending Kozloduy by adding two AP1000 reactors at the same site in the late 2030s.
