Energy supply – Energy Country Profile

Energy Supply


Bulgaria possesses a substantial amount of lignite reserves (approximately 2.2 Gt in 2020), but these reserves are quite difficult to extract due to their location under villages and cities.

Total primary energy supply (TPES) reached more than 210 TWh in 2020. 

TPES mix in 2020 was fairly even distributed between hard coal and lignite (23%), electricity (25%) and oil (27%)

Power Generation

Main energy sources for power generation are coal, and nuclear. Although coal is steadily declining since 2011. Renewable energies are still on the waiting line to play a more dominant role.


In 2020, coal contributed  (33%) to power generation in the Republic of Bulgaria. Nuclear power generation has taken over the first place with 41%.
