The Greek gas transmission system operator DESFA on Wednesday signed a memorandum of cooperation with its Bulgarian, Romanian and Hungarian counterparts - Bulgartransgaz, Transgaz and FGSZ, respectively - for the linking of their gas grids via a "vertical gas corridor" running from Greece to Hungary and Ukraine.
The agreement was signed in Bucharest and also includes the ICGB AD consortium, the contractor for the Greece-Bulgarian Interconnector (IGB) pipeline project. It calls for the cooperation of all the companies to promote the vertical gas corridor interconnector gas pipelines.
DESFA noted that this involves a combination of projects and actions that include intervention in existing grids and agreements for connected systems with common rules, enabling two-directional transportation of natural gas from Greece to Hungary and Ukraine.
It was preceded by an agreement signed by Greece and Bulgaria on June 1 that allows reverse flow of natural gas between the two countries.
