Grid Battery storage is now cheap enough to unleash India's full solar potential

10 hours ago

Solar plus battery systems could economically meet 90% of India's electricity demand at a cost of INR 5.06/kWh, but achieving 100% would be costlier.
To supply 90% of the 2,000 TWh demand, India would need 930 GW of solar capacity (less than a third of its potential) and about 2,560 GWh of battery storage.
During high-solar periods (Jan-Apr), batteries can shift daytime solar to meet nearly 100% of daily demand, but in monsoon months like July, output drops to 66% due to reduced solar generation.
A diversified energy mix, including wind power that peaks during monsoons, is essential for reliability, as batteries alone cannot cover extended cloudy spells.
