The project is related to the conversion of the depleted offshore natural gas field of South Kavala to the country’s first Underground Gas Storage (UGS) facility.

Preliminary planning refers to a capacity of approximately 950 mcm, ~350 mcm of which are recoverable at an injection rate of 5 mcm/d and an extraction rate of 4 mcm/d. At present, the South Kavala gas field in the Thracian Sea is in use by Energean Oil S.A.

The Hellenic Republic is assessing the best available option for the use, development and commercial exploitation of the asset as a natural gas storage facility.
