CESC awards 600 MW ISTS hybrid projects to Vismaya Renewables, Purvah Green, Hexa Climate, and Sprng Energy

Calcutta Electric Supply Corporation (CESC) has awarded 600 MW of ISTS-connected wind-solar hybrid projects to Vismaya Renewables, Purvah Green, Hexa Climate Solutions, and Sprng Energy. This development deal signifies CESC's commitment to diversifying its energy portfolio and incorporating renewable energy sources. The projects, located in India, will contribute to the country's growing hybrid energy capacity, leveraging both wind and solar resources for a more consistent power supply. Sprng Energy, a known renewable energy developer, is among the counterparties, suggesting a level of experience and expertise involved in the project's execution. The other developers, Vismaya Renewables, Purvah Green, and Hexa Climate Solutions, are less known based on the provided information. The financial details of the deal remain undisclosed, making it difficult to fully assess its economic impact. The award of these projects to multiple developers suggests a strategic approach by CESC to distribute risk and potentially benefit from diverse expertise. The ISTS (Inter-State Transmission System) connection is crucial, enabling the generated power to be transmitted across state lines, contributing to a more integrated and efficient national grid. The announcement date of 2026-02-27 indicates a forward-looking perspective, suggesting a planned timeline for project development and commissioning. The absence of signing and closing dates implies that the deal is still in its early stages, with further negotiations and agreements likely to follow.
