BRUSSELS, September 23. /ITAR-TASS/. Ukraine pumped 188 million cubic meters of gas into underground storage facilities from September 14 through September 21, raising the volume of stored gas to 16.444 billion cubic meters, according to the data provided by the GSE association on Tuesday.

Ukraine’s underground storage facilities are 51.47% loaded as of September 21.

Ukraine pumps gas, which it receives in a reverse mode from Europe and produces locally. The country has 12 underground gas storages with a total capacity of around 31 billion cubic meters.

Russia-Ukraine gas dispute

A trilateral gas meeting between Russia, Ukraine and the European Union is scheduled to be held in Berlin on September 26.

The previous discussions, launched on May 2, that involved EU Energy Commissioner Gunther Oettinger, Russian Energy Minister Alexander Novak and his Ukrainian counterpart Yuriy Prodan, ended on June 16 with no result.

Ukraine’s Naftogaz and Russian energy giant Gazprom later filed mutual claims to the Stockholm Arbitration Tribunal.

Ukraine currently does not receive Russian gas over an unsettled dispute over gas prices.

The Naftogaz oil and gas company stopped paying for the consumed Russian natural gas since March 25. As of August 1, the overall debt of Naftogaz to Gazprom for supplied gas totaled about $5.296 billion.
