All gas contained in the Ukrainian gas transportation system, including underground gas storage facilities, is accounted for in the technical gas balances. These gas balances are used for hydrocarbons transportation, accounting, storing and sales purposes.

Gas balance represented the biggest business challenge for the Misen Group and the JA during 2013 and the first half of 2014. Changing geopolitics and efforts of the management team to address the situation proved to be successful and during 2014-2017 the JA did not experience any complications with the gas balance situation.
