Mohammad-Reza Jolaei added five to 10 million cubic meters per day (mcm/d) of gas exported to Iraq have been on average reduced during a few past days due to the grid malfunction in western Iran, Tasnim News Agency reported.

The extreme heat in southern and southwestern Iran has caused glitches in production and transmission equipment, he explained.

Jolaei said the average gas exported to the neighboring country during the past month of Iranian calendar year (starting May 22) amounted to 30 mcm/d, concluding that the figure was decreased to 21 mcm/d this month (starting June 22) due to the technical problem.
