HPCL and Mittal Energy each have a 49% stake in the refinery with the remaining 2% held by Indian financial institutions.

HMEL chairman S. Roy Choudhury said, "This refinery will help in meeting the growing Indian hydrocarbon demand and more particularly help in bridging the large demand-supply mismatch of petroleum products faced in the northern region of the country."

The refinery will have a capacity of 9 million metric tons per annum,

The refinery will help feed fuel in the northern region of India and will have an environmental friendly distillate yielding complex, comprising of a petrochemical unit producing polypropylene and a captive 165MW power plant.

The import facility Single Buoy Mooring will berth very large crude carriers and will have a crude oil terminal at Mundra for blending a wider range of crude oils with environmental protection measures such as Sulphur recovery units.

A 1,017km cross country pipeline from Mundra to Bathinda to carry crude oil has also been built linking various intermediate pumping stations through Gujarat, Rajasthan, and Haryana reaching Punjab.

The refinery, construction of which began in 2008, had refined crude oil in August 2011, and kerosene and petroleum coke were first sold in February.
