Chennai Petroleum Corporation Ltd (CPCL) has officially requested government approval for its Rs 364 billion Cauvery Basin Refinery Project in Tamil Nadu, the company announced on Tuesday.

CPCL Managing Director H Shankar stated that the company has acquired approximately 1,300 acres of land in Nagapattinam for the proposed refinery, which is designed to process 9 million metric tonnes per annum (MMTPA).

Indian Oil Corporation, CPCL’s parent company, had in March 2024 approved a revised project cost, increasing it from Rs 293.61 billion to Rs 330.23 billion, reflecting updated estimates for construction and infrastructure. The refinery is expected to significantly boost the region’s refining capacity and contribute to India’s energy infrastructure expansion.
