Bulgaria's energy regulator said it decided to cut domestic natural gas prices by 9.87% from January 1.
The price will be decreased to 656.47 levs ($444.6/335.6 euro) per 1,000 cubic metres, Value Added Tax excluded, the State Energy and Water Regulatory Commission said in a statement.
Earlier this month Bulgaria's state-owned gas monopoly Bulgargaz requested that gas prices go down by 9.3% in the first quarter of next year.
Bulgaria's energy regulator revises gas prices on a quarterly basis.
Bulgaria imports almost all the natural gas it needs from Russia through a pipeline crossing the territories of Ukraine, Moldova and Romania.
