The Chiren underground gas storage facility is already full at 90.24% of its technical storage capacity, Bulgartransgaz said Thursday. Thus, for the second year in a row, the early fulfilment of the obligation to fill 90% of the storage volume in the European Union countries no later than November 1 of each year, set in the European Regulation 2017/1938 on measures to safeguard security of gas supply, has been achieved.

At present, a total of twelve companies - 7 Bulgarian and 5 international - store natural gas in the Chiren gas storage facility, the company said.

The Chiren facility is designed for storage of natural gas in order to cover seasonal irregularities in gas consumption and supply. State-owned company Bulgartransgaz is the owner and operator of the Chiren gas storage facility.
