The bloc is expected to reach a target of filling its storage facilities to 90% full by Nov. 1.
"EP Commodities transports natural gas to Ukraine and uses Ukrainian gas storage facilities," Miroslav Hasko, chairman at EPH's EP Commodities, said.
EU countries' gas storage facilities were 87% full on Aug. 7, according to transparency platform GIE.
"We consider gas storage in Ukraine as one of the interesting business opportunities that we are currently considering," SPP told Reuters.
