Foreign gas traders are keeping 4.4 bcm in Ukraine’s underground gas storage facilities – double the amount of this time last year

, reports Ukratransgaz. With Ukraine’s duty free warehouse regime gaining wider acceptance amongst EU companies, foreign-owned gas now accounts for 28% of the 15.5 bcm currently stored in Ukraine. Over the summer, when prices are low, the reservoir system is expected to fill to close to its 30 bcm total capacity.
