new delhi, Nov. 6 -- General Atlantic owned Actis Llp is interested in buying back Sprng Energy group from Shell Plc in a deal having an enterprise value of around $1.55 billion, two people aware of the matter said. If Actis indeed acquires Sprng, the deal would mark a full circle for the company, which had sold Sprng Energy to Shell three years ago at an enterprise value of $1.55 billion. Sprng Energy has 2.3 gigawatt (GW) of operational renewable energy projects, and 5GW in the pipeline. Other interested prospective bidders in the yet-to-be-launched sale process, run by Barclays, include the world's largest alternative asset manager Blackstone, and Canada's Brookfield Asset Management Inc., thepeoplesaid on the condition of anonymity. "Actis is interested in buying back Sprng Energy group from Shell Plc," one of the two people said. Shell recently sold its 49% stake in green energy firm Cleantech Solar to Singapore's Keppel Ltd, in a deal having an equity value of around $200 million, Mint reported earlier. Keppel, which already owns the balance 51% stake in the rooftop solar energy platform, plans to sell Cleantech Solar for around $400 million later. A Shell spokesperson in an emailed response said, "We continuously review our portfolio to deliver upon our strategy. We will not comment on market speculation. Sprng remains focused on safe, reliable operations." Spokespersons for Barclays, Blackstone and Brookfield Asset Management Inc. declined comment. An Actis spokesperson in an emailed response said, "As a firm, we are unable to comment on deal speculation." The massive scale of India's green energy space has attracted the attention of both Indian and global investors. India has an installed renewable energy capacity of around 197GW, and plans to add 50GW more annually to reach 500GW renewable capacity by 2030. The plan is to add 1,800GW of renewable energy capacity by 2047 and 5,000GW by 2070. Analysts say inorganic growth is the playbook in the energy space. According to KPMG, it is the top operational priority for organizations to achieve growth over the next three years, as they pursue greater energy security, build digital infrastructure, and scale renewables. "Mergers and acquisitions (M&A) remain on the agenda-notably for renewables and digital assets-suggesting an increased appetite for inorganic growth," the KPMG 2025 Global Energy, Natural Resources and Chemicals CEO Outlook report released on Tuesday said. Actis has been an active investor in India's green energy space. Blupine Energy is its third clean energy firm in the country, following the sale of Ostro Energy to ReNew Power Ventures in 2018 at an enterprise value of $1.5 billion, and the Sprng Energy deal. Also, it is exploring a sale of Blupine Energy in which it has invested $800 million to develop a 4GW renewable energy portfolio. Actis had earlier bought Macquarie Asset Management's green energy platform Stride Climate Investments with a 371MW portfolio, in a deal having an enterprise value of $325 million. While Brookfield has been an investor in India's green energy space, Blackstone has been examining the space and plans to set up a new renewable energy platform in India....
