KIEV, September 10. /ITAR-TASS/. Poland has suspended reverse-flow deliveries of natural gas to Ukraine, the head of the Ukrainian operator company, Ukrtransgaz, said Wednesday.

By tradition that has taken shape in Kiev’s ruling elite over the past several months, he apportioned all blame for the situation to Russia.

“Russia has begun to restrict the pumping of gas to Poland so as to frustrate the reverse-flow supplies to us,” said Ukrtransgaz President, Igor Prokopiv. “Poland stopped the reverse-flow supplies at 14:00 hours (11:00 hours GMT) in the amount of 4 mln cubic meters.”

Reverse-flow pumping of gas to Ukraine began in April 2014. Ukraine has the technological capability for receiving up to 4 mln cubic meters of the fuel a day.

Polish oil and gas corporation PGNiG (Polskie Gornictwo Naftowe i Gazownictwo) said earlier deliveries of gas from Russia had fallen 20% to 24% in the past two days at transfer stations. More specifically it claimed that the shrinkage totaled 20% on September 8 and 25% on September 9.

Jeremy Rzarzycki, the head of PGNiG’s Moscow office said it had sent a query to Gazprom Export, the exporting arm of the Russian gas giant Gazprom but there was no answer from it by the time of reporting.

Gazprom officials familiar with the situation were not available for comment when ITAR-TASS tried to contact them.

Ukraine consumes about 50 bln cubic meters of gas annually. In 2013, a total of 26 bln cubic meters came from Russia and another 2.1 bln cubic meters was purchased in Austria, Germany, Poland, and Hungary.

Own production of natural gas stands at 21 bln cubic meters.

Kiev government hopes to get about 16 bcm from European countries in 2014, with the biggest amount /8.0 to 10.0 bcm/ due to come Slovakia and another 5 bcm, from Hungary.
