IL&FS to construct 2 Solar PV & Wind Integrated power systems with energy storage facilities

As India's largest wind energy producer, IL&FS Energy Development Company Limited (IEDCL) aims to be an innovator in the development and application of energy storage technologies. Currently, the company is planning to construct two solar PV and wind integrated power systems with energy storage facilities: a 1000 MW integrated power system in the Ananthpur District of Andhra Pradesh and a similar but smaller scale 150 MW power system in the village of Nana Layja located in the Kutch District of Gujarat. The energy storage component of the TA project will primarily focus on the various types of battery technologies currently available and emerging in the Indian market. In fact, IEDCL is already generating 6.5 MW of wind power at the site and has basic power evacuation infrastructure already in place.

Thus, IEDCL is currently selecting consultant for evaluating and selecting energy storage technologies for the new wind-solar farms. IEDCL has existing renewable portfolio of 800 MW and has plans to deploy 5000 MW portfolio over next 5 years as part of Indian Government’s proposed rollout of 160 GW renewables (100 GW solar and 60 GW wind). If this study shows positive business case, then the actual Project will entail construction of 1150 MW of integrated renewable power generation (765 MW wind and 385 MW solar) with energy storage (173 MW). The Project would enable IEDCL to deliver dispatchable power to the grid; deliver peak power; improve grid reliability; and sell power through interstate PPAs. The Project has a total estimated capex of $1.9 billion for the full 1150 MW project. The energy storage component of the Project would cost $559 million. There is an estimated $798 million in potential U.S. exports, including $448 million for energy storage. IEDCL is considering range of technologies covering Li-Ion, Flow Batteries, CAES, Flywheels and advanced lead acid technologies for potential deployment under this project.
