Gas supply to industries in Iran has been limited, while domestic gas consumption has reached a critical level due to severe cold season, Tabnak news portal reported.
The country's domestic and commercial units` total gas consumption surpassed 482 million cubic meters per day on Dec. 30, which was a new record during the current solar year (started on March 21).
Supplying gas to power plants has been limited, and the country's main industries including steel, cement and petrochemical industries have faced gas shortage.
The gas supply to some CNG stations in Tehran as well as northern and western provinces was suspended due to shortage and low pressure, which led to severe increase in gasoline consumption.
Some 50 percent of the CNG stations in Tehran were closed due to shortage and low pressure, chairman of the board of directors of the union of Iranian CNG station owners, Ardeshir Dadras said.
Earlier Iranian Deputy Oil Minister Hamidreza Araqi urged households to economize on the consumption of natural gas.
"If consumption is not limited, gas supply to power plants, industrial units, and households will be reduced," Araqi said, the Mehr News Agency reported on Dec. 13.
Iranian Oil Minister Bijan Namdar Zanganeh said on Nov. 29 that the coming winter will be the hardest one in the country's history in terms of gas shortage.
However, Zanganeh said that the Iranians will face no difficulty in the season, the IRNA News Agency reported.
The Mehr News Agency previously reported that based on data collected by Iran's Oil Ministry, the country needs over 700 million cubic meters of gas per day in the coming winter.
According to the U.S. Energy Information Administration report, Iran's natural dried gas output was about 153 billion cubic meters which is as much as the domestic consumption figures.
According to this report released in March 2013, overall, Iran's natural gas consumption is expected to grow around seven percent annually for the next decade.
Iran has 33.6 trillion cubic meters of gas reserves.
