Bulgaria possesses a substantial amount of lignite reserves (approximately 2.2 Gt in 2021), but these reserves are quite difficult to extract due to their location under villages and cities.
Total primary energy supply (TPES) reached more than 230 TWh in 2021.
TPES mix in 2021 was fairly even distributed between hard coal and lignite (27%), electricity (21%) and oil (27%)
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 2021, coal contributed (36%) to power generation in the Republic of Bulgaria. Nuclear power generation just a bit behind with 35%.
