Bulgaria's gas monopoly Bulgargaz proposed that the price local consumers will pay for natural gas in the first quarter of 2014 should remain unchanged at the end-2013 level.
The company proposes keeping a price of 630 levs ($427/322 euro) per 1,000 cubic metres for the first three months of 2014, net of value added tax and excise duties, it said in a statement published on its website.
The price adjustment, made on a quarterly basis, must be approved by the Bulgarian energy regulator to take effect.
Bulgaria imports almost all the natural gas it needs from Russia through a pipeline crossing the territories of Ukraine, Moldova and Romania.
