Introduction
In a big development in the renewable energy sector in India, Reliance NU Energies, a subsidiary of Reliance Power, has won a big solar power project from state-owned SJVN Ltd. The project features 350 MW of solar capacity with an integrated 175 MW/700 MWh Battery Energy Storage System (BESS).

The announcement, which was made on Monday, is historic for Reliance NU Energies as it deepens its presence in India’s clean energy transition. The built-in battery system is poised to provide 175 MWh of backup power with four hours’ duration, enhancing grid reliability and peak power demand management.
Competitive Tariff Positions Project as a Game-Changer
What distinguishes the project most prominently is the tariff: at ₹3.33 per unit per kWh, for 25 years, it is one of the lowest-cost renewable energy-plus-storage propositions in the country. This is a reflection of Reliance NU Energies’ emphasis on cost-effective long-term energy solutions and makes it the best among the clean energy players.
This tariff will act as a benchmark for solar-plus-storage tenders to be held in India in the future, say industry analysts. As power demand is growing and as energy security and sustainability gain prominence, such combined solutions are likely to become more popular.

A Big Boost to India’s Green Energy Aspirations

This victory also adds to India’s ambitious 500 GW non-fossil fuel capacity target by 2030. By integrating battery storage and solar power, Reliance NU Energies is overcoming the intermittency challenges of renewable energy, creating a more stable and robust power grid in the process.
