On 25 December 2008, Reliance Petroleum Limited (RPL) announced the commissioning of its refinery into a Special Economic Zone in Jamnagar district of Gujarat, India. The completion of the RPL refinery has enabled Jamnagar to emerge as a ‘Refinery Hub’, housing the world's largest refining complex with an aggregate refining capacity of 1.24 million barrels (197,000 m3) of oil per day, more than any other single location in the world.
The entire complex, as of 2013, consists of manufacturing and allied facilities, utilities, off-sites, port facilities and a township (415 acres) with housing for its 2,500 employees, on over 7,500 acres (3,000 ha; 11.7 sq mi) of land.
