Indian Oil Corporation (IOC) has announced a substantial investment of over Rs 21,000 crore in expanding the Barauni refinery in Bihar and establishing a city gas distribution network across the state. The expansion plan includes increasing the refinery capacity from 6 million tonnes to 9 million tonnes per annum, along with setting up a petrochemical plant and a network to distribute CNG and piped cooking gas in 27 cities of Bihar. The company's Executive Director, Suman Kumar, highlighted that IOC, as the oldest investor in Bihar, had set up the Barauni refinery in 1964 and is now further expanding its operations in the region. The investments also involve setting up a polypropylene plant, which will serve as a raw material for the plastic industry. The expansion and polypropylene plant are scheduled to be operational by the end of 2025. IOC is also focusing on green initiatives such as hydrogen mobility, biofuels, and renewable energy, in alignment with India's increasing energy needs and the government's target to achieve 500 GW of installed renewable capacity by 2030. The article emphasizes IOC's vision to become a USD 1 trillion company by 2047 and play a significant role in fulfilling India's energy requirements by 2050. The company is not only expanding its refining capacity but also integrating petrochemical units and investing in renewable energy assets. This expansion plan is part of IOC's efforts to meet the growing energy demands of India, with projections indicating a rise in oil demand from 5.4 million bpd in 2023 to 9.3 million bpd by 2040. With a focus on economic growth, infrastructure development, and sustainable energy solutions, IOC's expansion in Bihar represents a step towards enhancing energy security and meeting the evolving energy landscape.
