India's Energy Storage to Surge 10-Fold by 2026: IESA Report

• India's battery energy storage capacity is projected to surge 10-fold to 5 GWh in 2026 from 507 MWh in 2025, driven by a large project backlog.
• The year 2025 saw unprecedented tendering activity with 69 tenders totaling 102 GWh, nearly matching all tenders from 2018-2024 combined.
• 2026 will be a critical year for operational proof, with 60 GWh of projects entering implementation and cumulative capacity under execution reaching 224 GWh.
• Tariffs for standalone BESS and solar-plus-BESS projects plummeted in 2025, attracting over 50 new bidders and intensifying market competition.
• Key projects include Adani's 1,126 MW/3,530 MWh BESS in Gujarat by March 2026 and Rajasthan's tender for India's largest solar-plus-BESS at Pugal Solar Park.

Why It Matters: India's energy storage sector is set for a transformative operational breakout in 2026, driven by massive project execution and policy support.
