Russian Gazprom reduced daily natural gas supplies to Turkey by around 50 percent from Feb. 10 along the western line, according to Russian news agency Interfax.
Russia's Interfax quoted figures from Bulgarian state gas company, Bulgartransgaz, and said that the Russian company decided to reduce its natural gas flow after a price dispute with private buyers in Turkey.
Earlier it was reported that Russia's Gazprom, who was in discussions with six Turkish private companies on Jan. 29, cancelled the 10.25 percent discount applied on natural gas supplies from Gazprom from Jan. 1 this year.
Gazprom sent 26.7 million cubic meters of natural gas to Turkey through the western route on Wednesday; however, this figure was around 40 percent higher last year on the same day.
"It may be to do with the warm weather especially in Istanbul," Interfax said.
Turkey's Energy Ministry sources told Anadolu Agency Thursday that Gazprom issued an invoice to Turkish private companies showing costs 10.25 percent more than the agreed deal indicating a cancellation of the 10.25 percent discount.
"There is no [technical] problem with the gas flow," Turkish sources said.
Turkey, which is the second biggest consumer of Russian gas after Germany, imports around 30 billion cubic meters of gas from Russia annually via two pipelines; the Blue Stream and the western line. The private sector in Turkey imports 10 billion cubic meters (bcm) of natural gas per year, representing over 30 percent of Russia's gas imports to Turkey.
Turkish private gas importers include Bosphorus Gaz, Enerco Enerji, Bati Hatti, Kibar Enerji, Avrasya Gaz and Shell Enerji.
Out of 48 bcm, 38 bcm was imported by the state-owned crude oil and natural gas pipeline and trading company, BOTAS. Gazprom was due to enforce the 10.25 percent discount with BOTAS; however the company confirmed that this has never been applied.
