Electricity sector in Bulgaria


The electricity sector in Bulgaria is an important part of energy in Bulgaria and is highly diversified. Nuclear is the largest source of power followed by coal and solar.

Power production

Bulgaria consumes about 35 TWh of electricity per year, and some is exported. The residential sector is the largest consumer, followed by industry then services.

Coal power

Some power stations are very dirty, and in 2023 one was found guilty of excess sulphur dioxide air pollution, which might lead to court cases against others.
In early 2023 the government attempted to postpone Bulgaria's EU commitment to reduce greenhouse gas emissions by 10% that year, because it did not want to close any coal-fired power stations.
Fossil fuel subsidy of coal power is expected to end by 2025. Bulgaria aims to phase out coal power by 2038 or earlier. The Center for Research on Energy and Clean Air says that an earlier phase out would save many lives and much money.

Solar power

Europe's largest grid battery at 124 MW / 496 MWh opened at the 106/86 MW solar park in Lovech in May 2025. A 69 MW section at the Tenevo 238 MW solar park opened in 2025, with 65 MW/260 MWh of a planned 315 MW/760 MWh battery energy storage system.
