A fire at HPCL Rajasthan Refinery’s Balotra complex has delayed the public rollout of one of India’s largest downstream energy projects just as it approached commercial start-up, pushing attention from inauguration optics to commissioning risk, plant readiness, and capital discipline.
The blaze broke out on Monday in the vicinity of the crude distillation unit, or CDU, the front-end unit where crude first enters the refinery. The Ministry of Petroleum and Natural Gas said the fire was brought under control, no casualties were reported, and Prime Minister Narendra Modi’s planned April 21 dedication ceremony was postponed pending a revised date.
HPCL said the preliminary cause appears to be hydrocarbon leakage from a valve or flange in the heat exchanger circuit. The company said the fire was localized in the heat exchanger stack, while the CDU, vacuum distillation unit, and related units were isolated quickly. HPCL added that all units are structurally safe and unaffected and that no other section of the refinery suffered impact.

The company has started an investigation with remedial measures underway. HPCL later said in an exchange filing that the financial and operational impact, if any, is being assessed and prima facie is not expected to be material.
The Rajasthan project is not a routine refinery addition. HRRL is a 74%-26% joint venture between Hindustan Petroleum Corporation and the Government of Rajasthan, built as a greenfield integrated refinery-petrochemical complex at Pachpadra in Balotra district with nameplate capacity of 9 million metric tonnes per annum, including 2.4 MMTPA of petrochemical products. The complex is designed to process 7.5 MMTPA of imported crude and 1.5 MMTPA of Rajasthan crude.
Earlier, India’s cabinet approved a revised project cost of ₹79,459 crore ($8.53 billion) from ₹43,129 crore, an increase of about 84%, while also approving additional equity investment by HPCL to maintain its 74% stake. The government said commercial operations were targeted from July 1, 2026.
Once operational, it will add 9 MMTPA to the country’s refining system and deepen petrochemical output at a time when India is expanding downstream infrastructure despite high crude import dependence. Reuters reported in January that the Barmer refinery would make HPCL India’s second-largest state-run refiner by capacity.
