Bulgaria has two nuclear reactors generating about one-third of its electricity. · Bulgaria’s first commercial nuclear power reactor began operating in 1974.

Hydroelectricity is a major form of energy supply in Bulgaria. The country’s HEP stations have over a quarter of the country’s entire installed capacity for electricity production (2 713 MW of a total of 9 728 MW, or 27.9%).

Bulgaria has 700 MW of wind power installed today, covering 4% of its electricity demand. Last year, wind power overtook coal as the second-largest power capacity in the EU, providing now more than 10.4% of the EU’s electricity demand. Wind power is not only abundant but also competitive in Bulgaria today.
