Russian energy giant Gazprom cut off its gas supplies to Germany via the Nord Stream 1 pipeline for maintenance work on Wednesday, further raising tensions on an already taut electricity market.
Entsog, the operator of the pipeline, announced that gas deliveries had been halted shortly before 0600 GMT.
"The estimated price of natural gas will be around BGN 350 (EUR 179), which is an increase of around 17 percent compared to the price for August," said Denitsa Zlateva, executive director of Bulgargaz, after the meeting of the Commission for Energy and Water Regulation.
According to her, this is due to the increased stock market index.
The price of natural gas on the Dutch exchange TTF reached 341 euros per megawatt hour yesterday, and electricity supply contracts in Germany and France broke all records. Against this background, the Czech Presidency of the European Union announced that it is preparing an extraordinary meeting of energy ministers.
The leader of GERB and ex-Prime Minister, Boyko Borissov, accused former PM Kiril Petkov and former deputy PM Asen Vassilev of deliberate actions and sabotaging the supplies of American liquefied gas in Bulgaria.
According to Borissov, Petkov's office did not sign the contract and did not reserve a delivery point for unloading the tankers.
