- Ember modeled that solar paired with battery storage could supply 90% of India’s electricity demand at an LCOE of INR 5.06/kWh.
- India’s electricity demand exceeded 2,000 TWh in 2024, and meeting 90% would require roughly 930 GW of solar capacity and 2,560 GWh of battery storage.
- Solar‑plus‑storage would need about 4.9 GW of solar and 13.5 GWh of battery storage for each 1 GW of average demand, with only 5% of annual solar generation curtailed.
- India had installed 143 GW of solar capacity by February 2026, roughly 4% of its estimated 3,343 GW ground‑mounted solar potential.
- Battery storage can shift daytime solar generation to evening and night during January‑April, enabling the system to meet close to 100% of demand on most days, and about 88% in the peak May‑June period.
- Full solar alone is technically possible but would be significantly more expensive, as each extra percentage point of demand coverage requires disproportionately more solar and storage capacity.
Why it matters: The finding gives India a concrete, low‑cost route to supply 90% of its electricity with solar‑plus‑storage, opening market opportunities for solar developers and battery manufacturers while reducing reliance on other generation sources. It also highlights that achieving 100% solar would be disproportionately expensive, tempering expectations for an all‑solar grid.
