Pachpadra Refinery: India’s Most Delayed, Most Contested, and Most Important Energy Project
IntroductionFor over a decade, the Pachpadra refinery in Rajasthan’s Balotra district has been India’s most politically freighted infrastructure project — a facility that has had two foundation stones laid by two different prime ministers from two different parties, a cost that nearly doubled before a single barrel was processed, and an inauguration that was stopped one day before it was to happen by a fire that broke out in the Crude Distillation Unit.It is also, when you set aside the politics and the delays and the drama, one of the most consequential energy projects India has built in a generation.HPCL Rajasthan Refinery Limited, known as HRRL, is a 9 million metric tonnes per annum greenfield refinery-cum-petrochemical complex with 2.4 million metric tonnes per annum petrochemical production capacity, located in Pachpadra, Balotra district, Rajasthan. It is India’s first greenfield integrated refinery-cum-petrochemical complex, built at an estimated cost of nearly Rs 80,000 crore. It is spread across 4,400.4 acres of land in the Thar desert, operated by HPCL Rajasthan Refinery Limited, with HPCL holding 74 percent and the Government of Rajasthan holding 26 percent.When it becomes fully operational, it will be the first major refinery India has built from scratch since the 1990s — and the first one specifically designed to process the heavy, waxy crude oil that sits beneath Rajasthan’s Barmer basin, one of India’s most significant onshore oil reserves.The Origin Story: A Project That Belongs to Every PartyThe Pachpadra refinery’s political genealogy is unusual even by Indian standards. No single government can claim it. Every government has tried to.The story begins not with a foundation stone but with oil. The discovery of the Mangala oilfield in Barmer — the largest onshore oil discovery in India in more than 22 years at the time — created an obvious question: why is all this crude being pumped out of Rajasthan and sent to refineries in Gujarat and Maharashtra? Why is Rajasthan not refining its own oil?The project was first conceptualised under the Congress government. On September 18, 2013, then Congress president Sonia Gandhi laid the first foundation stone for the project, with an initial estimated cost of Rs 43,129 crore. The Ashok Gehlot government in Rajasthan was a co-signatory, and the project carried the political imprimatur of both the state and central Congress establishments.Then came 2014. The Congress lost the general election, Vasundhara Raje’s BJP government came to power in Rajasthan, and a project associated with the Congress went into the freezer — not officially abandoned, but quietly deprioritised. The joint venture structure was complicated, the land acquisition was incomplete, and the financing arrangements required renegotiation.Four years later, the BJP arrived to claim the project as its own. On January 16, 2018, Prime Minister Narendra Modi laid a second foundation stone for the same project, which now had two foundation stones from rival parties. Modi declared that the refinery would be ready by 2022 and would change the economic landscape of Rajasthan. He was wrong about 2022. He was not wrong about the economic landscape.The Project: What Is Actually Being BuiltThe refinery is operated by HPCL Rajasthan Refinery Limited, with HPCL holding 74 percent and the Government of Rajasthan holding 26 percent. An MoU for the project was signed between the state government and HPCL on April 18, 2017.The facility is not simply a refinery. The integrated nature of the project — combining refining with a large-scale petrochemical complex on the same site — is what makes it distinct from existing Indian refineries and from the original 2013 design.The refinery has a capacity of 9 million metric tonnes per annum of refining and 2.4 million metric tonnes per annum of petrochemical production. The Scheduled Commercial Operation Date is July 1, 2026.The petrochemical capacity is particularly significant. India is one of the world’s largest importers of petrochemical products — the plastic resins, synthetic fibres, rubber, adhesives, and industrial chemicals that feed into every sector of manufacturing. A domestic integrated complex reduces that import dependence and creates a foundation for downstream manufacturing investment in Rajasthan.The crude feedstock for the refinery will be Mangala crude from the Barmer basin — heavy and waxy crude that requires specialised handling including insulated pipelines and dedicated processing units. The Mangala field, discovered in January 2004, is the largest onshore oil discovery in India in more than two decades. It sits directly in Rajasthan’s backyard, and Pachpadra was designed specifically to process it, eliminating the need to transport it all the way to coastal refineries in Gujarat.HRRL is an important project considering the growing energy needs and petrochemical requirements of the country, thereby reducing the country’s dependence on imports, which will result in saving foreign exchange. The project will also contribute towards industrialisation of a backward area, usage of locally available Mangala crude and help promote India as a refining hub.The Cost: From Rs 43,129 Crore to Rs 79,459 CroreThe most uncomfortable aspect of the Pachpadra story is its cost trajectory. The initial estimated cost of the refinery was Rs 43,129 crore, and the work was scheduled to be completed by October 31, 2022. During the previous state government’s tenure, the project cost increased to Rs 72,937 crore by June 2, 2023. HPCL Rajasthan Refinery Limited submitted a proposal for a second revision of the refinery’s cost to the state government on July 24, 2025.The total project cost has been revised to Rs 79,459 crore. The Union Cabinet approved the revised cost on April 8, 2026 — just twelve days before the inauguration fire.That escalation — from Rs 43,129 crore to Rs 79,459 crore — represents an 84 percent increase from the original estimate. Several factors contributed to it: the construction delays caused by land acquisition disputes and coordination failures during the political transitions between Congress and BJP governments in both Rajasthan and at the centre; Covid-19 disruptions that halted construction for an extended period; global commodity price inflation that drove up the cost of steel, cement, and equipment; and the expansion of the petrochemical complex beyond the
