Reliance Power unit to develop 930 MW solar plus battery project from SECI

The company will also install a battery energy storage system.

Reliance NU Suntech Private Limited (Reliance NU Suntech), a subsidiary of Reliance Power Limited, is set to develop the 930 megawatt (MW) solar energy with battery energy storage system project it secured from Solar Energy Corporation of India (SECI) in a recent e-reverse auction.

In a statement, the parent company said this project is the largest individual allocation out of the five companies vying for a total quoted capacity of 2,000 MW of Inter-State Transmission System (ISTS) connected solar power projects with 1,000 MW/4,000 megawatt-hours (MWh) energy storage systems.

Reliance NU Suntech will develop the project on a build-own-operate basis and will have to connect to the interstate transmission system in compliance with Central Electricity Regulatory Commission regulations for interconnection with the ISTS or InSTS.

Under the terms, the company will also install a minimum storage capacity of 465 MW/1,860 MWh charged by solar power.

The project will guarantee a peak power supply of four hours daily. SECI will also enter into a power purchase agreement with Reliance NU Suntech for 25 years to procure and sell solar energy to distribution companies in India.
