More than 15.5 million megawatts of natural gas were transported in 2023 through Interconnector Greece-Bulgaria Pipeline (IGB), according to the system’s manager, ICGB, on Wednesday.

ICGB also noted that the pipeline was operational for all 365 days last year, without interruption.

The pipeline, with a capacity of three billion cubic meters of natural gas per year (bcm/y), covers half of Bulgaria’s annual demand, while allowing the transport of natgas to other regional countries.

The IGB pipeline was used to transport natural gas to Moldova and Ukraine last year via the Trans-Balkan route, a milestone in diversifying energy sources.

The year also witnessed the first auctions for interconnection capacity, which guaranteed more than 80% of reserved capacity for the new production year (i.e. from Oct. 1 to Sept. 30 of 2024).
