The demand is covered by the withdrawal of gas from the USFs in the capacity of 101 mcm [per day], that is the largest volume of daily withdrawal in the current heating season," he said on Sunday, February 25. Gas is also imported from Europe (16 mcm per day) and produced by Ukrainian companies (57 mcm per day), the official added. "As of this morning, daily gas consumption has increased in Ukraine to 170 mcm. Some 10.4 billion cubic meters of gas remain in the USFs," Beliavsky said.
