The Aditya Birla Group (ABG) has tapped State Bank of India and Axis Bank for ₹15,000 crore in term loans to fund a potential acquisition of Sprng Energy, which is currently owned by Shell Plc, according to people aware of the development.ABG is said to be preparing an all-cash offer for Sprng Energy that could surpass Adani Green Energy's 2021 takeover of SB Energy in terms of cheque size or equity value, they said. That deal is seen as the largest M&A in the Indian renewable energy sector so far.The syndicate of banks financing the potential acquisition could expand, said the people cited. It is likely to be dominated by Indian banks though Japan's MUFG is also party to the financing discussions, they said.ABG could raise rupee term loans with a tenor of 5-10 years to finance the acquisition."It depends on what they are comfortable with. They may go for shorter tenor loans. Terms and conditions are still being discussed and are not finalised," said a person familiar with the matter.Birla has been discussing the acquisition of Sprng Energy from Shell for several weeks, as per the sources. The deal requires approval by Shell's London headquarters. An Asia Pacific-based team of the oil major has been negotiating the sale, they said."They (Shell) are solely negotiating with Aditya Birla for the sale of Sprng," said another person aware of the matter.ET was first to report January 31 that Aditya Birla was among four shortlisted to bid for Sprng Energy. It was first to report on May 14 that Aditya Birla and KKR were the final two contenders after four parties had submitted binding financial offers.Sprng Energy has a renewable energy generation portfolio of 5 gigawatts and its output is contracted to reliable counterparties such as state-owned entities in India.The company was incubated by Actis, which sold it to Shell in 2022.SBI, Axis Bank and MUFG did not comment on the matter. Aditya Birla Group's spokesperson was unavailable for comment."Shell confirms it is in initial discussions with potential partners interested in our Sprng business. It is too early to comment on an outcome of these discussions," a company spokesperson said.The sale plans are the result of a strategic rethink at the oil company, the shareholders of which are said to be nudging it to focus more on the core business of exploration and production
