Reliance Infrastructure has secured a letter of award (LoA) from NHPC, a Navratna Central Public Sector Enterprise, for the development of a 390 MW interstate transmission system (ISTS)-connected solar power project coupled with battery energy storage system (BESS).

Once commissioned, the project will add 700 MWp of solar DC capacity and 780 MWhr of BESS capacity to the Reliance Group’s portfolio, reinforcing its leadership in integrated new energy solutions. The order was awarded at a tariff of Rs 3.13/kWh, placing it among the most competitive in India’s renewable energy transition. It emerged from a tender floated by NHPC that attracted strong participation from 15 bidders, with 14 qualifying for the e-reverse auction.

Reliance Power, part of the Reliance Group, already manages a portfolio of nearly 2.5 GWp solar and 2.5 GWhr BESS. With this win, the Group’s clean energy pipeline expands to over 3 GWp solar DC and 3.5 GWhr BESS, making it the country’s largest integrated Solar + BESS developer.
