The state-run gas company, National Iranian Gas Company, warned of the shortages there, and added that a "nationwide" cut in supplies could follow.
The company urged consumers to conserve fuel.
Deputy Oil Minister Hasan Kasai told ILNA on January 1 that gas consumption has risen by 45 percent year-on-year.
