Economic Advisory Council Calls for Rapid Scale-Up of Grid-Scale Battery Storage

India's Economic Advisory Council to the Prime Minister has recommended rapid scale-up of grid-scale battery storage systems, identifying a critical infrastructure gap in India's electricity ecosystem. The focus has shifted from capacity generation to managing availability and flexibility.

Background: India added 109+ GW renewable capacity by 2024, with solar comprising 70+ GW. However, solar's intermittency creates grid challenges: peak supply during mid-day causes frequency regulation issues, while evening demand peaks create supply gaps. Battery storage enables load shifting, frequency regulation, and grid stabilization. Current battery storage capacity remains negligible compared to generation capacity.

Key Facts: (1) Rising solar power causes significant day-night price volatility in electricity markets; (2) Grid stress peaks during morning and evening demand surges; (3) Battery storage currently represents <1% of India's total electricity infrastructure; (4) Global BESS capacity exceeded 30 GW in 2023; India lags significantly; (5) EAC projects critical need for 100+ GWh by 2030.

Why It Matters: Battery storage is foundational for India's renewable energy target of 500 GW by 2030. Without storage, renewable integration faces physical limits. Grid reliability, electricity prices, and industrial competitiveness depend on solving this challenge. Also supports electrification targets for transport and heating.
