The proposed expansion aims to boost the refinery’s current 210,000 bpd capacity, though the company has not yet established a formal timeline for the project. The Manali site remains a critical hub for the production of fuels, lubricants, and specialized petrochemicals. This development follows a strategic shift for the company, which previously shuttered its Cauvery Basin Refinery in 2019 due to outdated technical configurations.

Rather than reviving traditional refining at the Nagapattinam site, the company is now prioritizing a transition toward a dedicated petrochemicals complex. This new facility, in which Indian Oil Corporation maintains a 75% stake, reflects a broader corporate pivot to address rising domestic and international demand for specialty chemicals. These infrastructure moves align with wider national trends, as the International Energy Agency reports that oil refining investments in India have surged by 23% over the last five years. Such capital allocation positions the nation for a 15% increase in total refining capacity by 2030, reinforcing the country's status as a growing energy powerhouse.
