Tata Power Co. is targeting a near four-fold growth in its renewable generation capacity to 15 gigawatts by 2027 as the country’s second biggest private generator seeks to decarbonize operations.

The unit of Tata Group, one of India’s oldest conglomerates, has four gigawatts of operating renewable electricity capacity and another four gigawatts are under implementation, Praveer Sinha, chief executive officer, said in an interview at the sidelines of the Vibrant Gujarat summit.
