Talking to Shana, Hashemi said successful observation of the indices specified in the energy road map will result in 20 percent cut in energy consumption in the Tehran Refinery.
He said energy consumption in Tehran Refinery is daily gauged through macro energy indices system.
He added that Iranian refineries consume energy 30 percent more than that by the best American refineries.
Once the energy road map is prepared and the specified indices are met, energy consumption in the refinery will be less than five percent, he added.
The official said enforcement of the project and standardization of energy consumption in Tehran Refinery will take five years.
Tehran Oil Refining Company is 15 kms south of Tehran and has two southern and northern refineries.
