The gas storage in Chiren is completely filled and ready for the winter period

The underground gas storage "Chiren" is already filled to 100% of the technical storage capacity. According to the requirements of the European Regulation 2017/1938 on measures to guarantee the security of gas supplies, no later than November 1 of each year, gas storage facilities in the countries of the European Union must reach at least 90% of their volume. In 2024, for the second year in a row, this requirement was achieved by Bulgaria ahead of schedule.

The only Bulgarian gas storage is of essential importance for the energy security of Bulgaria and the countries of the South-Eastern Europe region. The achieved filling level contributes to guaranteeing the security of natural gas supplies for the upcoming heating season.

A total of 12 companies - 7 Bulgarian and 5 international - store natural gas in the Chiren gas storage facility.

The Bulgarian gas transmission operator continues the implementation of the measures in connection with the coming autumn-winter period.
