KYIV, March 20 – Ukraine plans in the spring and autumn of 2019 to increase the volume of gas pumped into its underground gas storage facilities (UGS) by 3 billion cubic meters (bcm) to start the next heating season with the reserves of about 20 billion cubic meters, head of Naftogaz Ukrainy Andriy Kobolev said.

"We are carrying out an assessment of what we need in order to survive the toughest option. To get through this winter we need to pump 3 billion cubic meters of gas more into UGS than we usually put in there," Kobolev said in an interview with RBC-Ukraine.
