"The stress test, joined by all suppliers, turned out well. We are ready for the winter, supplies are sufficient," stressed Vice-premier and Economy Minister Richard Sulík.

Gas supplies for the period between November 1 and March 31 were assessed in the stress test. The test will be updated during the heating season with regard to the weather developments.

If the winter is average in terms of temperature, then there is enough gas in Slovakia and the country has a reserve already now, claims the ministry.

Slovakia would consume 3.2 billion cubic metres (bcm) of gas if there was an average winter.

If there was a colder-than-average winter, Slovakia's gas consumption during the heating season is estimated at 3.5 bcm
