JSW Group is looking to sell a minority stake in JSW Neo Energy, a subsidiary of listed JSW Energy, to raise up to $500 million, people aware of the development told ET. The steel and energy conglomerate has appointed Standard Chartered Bank as the sell-side advisor for the transaction, one person said, asking not to be named as the discussions are private. TPG's The Rise Fund, which invests in clean energy companies, is one of the interested bidders. The fund had earlier invested $1 billion in Tata Motors' electric vehicles arm.
