Gas Export to Turkey Halted for Repairs 

Iran’s export to Turkey was stopped on Oct. 2 and will not resume until Oct. 9 due to repair operations underway on Iran-Turkey natural gas pipeline. 
During the period, natural gas will not be delivered to the transmission network from Gurbulak entry point, IRNA reported.
However, no problems are foreseen regarding supply-demand balance in the national gas network while the pipeline is undergoing repairs, an announcement by the Turkish Petroleum Pipeline Company said.
A disruption in gas flow to Turkey had also occurred in 2020 due to a pipeline explosion and it took over three months to fix it.
Gas flow to the neighboring country has been interrupted at least 10 times in the past two decades mostly due to terrorist attacks carried out by the banned Kurdistan Workers' Party, or PKK.
Iran started selling gas to Turkey in 2001 and exports about 30 million cubic meters per day of gas to the neighboring country now. Annual export of the fuel is around 10 billion cubic meters. 
Turkey buys around a quarter of its 40 billion cubic meters of piped natural gas a year from Iran, making its eastern neighbor the second biggest supplier after Russia. Natural gas is used for almost half of Turkey's electricity generation.
