Polskie Górnictwo Naftowe i Gazownictwo (PGNiG), Poland's largest state-controlled oil and natural gas company, has already used more than 70 percent of the natural gas it contracted from Russian supplier Gazprom for 2010.

Increasing the flow of gas is possible, but not without amending international agreements, a process that takes time, hence a worry that Poland could well run out of gas this winter.

Maciej Kaliski, director of the oil and gas department at the Economy Ministry, admits Poland will use up all Russian gas supplies by September 20. He warns an energy crisis could be coming to the country if PGNiG and Gazprom don't hammer out a new deal soon.
