In 2011, Bulgaria's lignite output stood at 34.5 million tonnes and its anthracite production stood at 2.4 million tonnes.

Bulgaria's coal imports decreased from a rate of 3.3 million tonnes in 2011 to 1.7 million tonnes in 2013.

According to Eurocoal data, the EU27 (excluding Croatia) produced 407 million tonnes of lignite in 2013, compared to 433 million tonnes of lignite in 2012. Anthracite output in the EU also fell from a rate of 128 million tonnes in 2012 to 114 million tonnes in 2013. However, imports registered a slight increase from 211 million tonnes to 216 million tonnes.
