According to a report by Ember, solar energy combined with battery storage has the potential to meet 90% of India's electricity demand at a levelized cost of electricity (LCOE) of ₹5.06/kWh. This finding indicates that solar power could provide reliable energy day and night, particularly in states with high solar irradiance. The study emphasizes that seven out of the ten largest states in India could source at least 83% of their electricity from solar and battery systems at a lower cost than current average purchase rates. The report highlights the dramatic improvements in battery economics over the past two years, which have made solar energy a more viable option compared to traditional fossil fuels. As India anticipates peak power demand to reach 270 GW this year, the transition to solar could serve as a buffer against global energy supply disruptions, particularly amidst rising coal prices and geopolitical tensions affecting gas supplies.
