Reliance NU Suntech, a subsidiary of Reliance Power, has won a landmark 930 MW solar project paired with a 1,860 MWh battery energy storage system in an e-reverse auction conducted by the Solar Energy Corporation of India (SECI). The project, the largest of its kind in India, will include a minimum storage capacity of 465 MW/1,860 MWh charged entirely by solar energy. This storage capacity ensures a power backup of up to four hours, providing a total energy output of 1,860 MWh.
The company secured the project at a competitive tariff of ₹3.53 per kWh and is awaiting the Letter of Award (LoA) from SECI. Once awarded, the project will be developed under a build-own-operate model and integrated into the interstate transmission system (ISTS) following Central Electricity Regulatory Commission (CERC) guidelines.
SECI’s Tranche XVII auction, under which this project was awarded, targetd 2,000 MW of ISTS-connected solar capacity with 1,000 MW/4,000 MWh energy storage. As a key government agency, SECI plays a pivotal role in advancing renewable energy initiatives in India. This achievement marks a significant step for Reliance NU Suntech and underscores India’s commitment to expanding renewable energy capacity and integrating advanced storage solutions.
