India, Aug. 20 -- Solar power paired with battery storage can deliver firm round-the-clock renewable electricity at an estimated Rs 5.15 per unit, according to a new IECC study.

The estimate is below the Rs 5.26 per unit tariff discovered in SECI's 1,000 MW round-the-clock renewable energy auction.

The study found that a 3GW solar plant with 12GWh of battery storage could meet the tendered supply profile in Rajasthan.

Researchers said India's stable year-round solar resource makes batteries well suited to shifting daytime solar power into evening and night demand.
