Piramal Enterprises has tied up with Canadian Pension Fund CPPIB to roll out India's first renewable energy infrastructure investment trusts. In a conversation with CNBC-TV18's Nisha Poddar, Piramal group's chairman Ajay Piramal said that the listing of this InvIT will take place in six to nine months. Talking about the rationale behind this decision, Piramal added that the IPO market is risky for renewable energy companies and an InvIT offers stable return from operating renewable assets.
