The LDES Council has released a new policy whitepaper titled “System Needs and Policy Imperatives for Long Duration Energy Storage (LDES) Solutions in India,” outlining a strategic roadmap for integrating long-duration storage into India’s evolving power system.
The report highlights new structural problems as India speeds up toward its goal of 500 GW of non-fossil fuel capacity by 2030. Renewable energy sources, especially solar and wind, are growing quickly, but the lack of enough long-term storage is making the grid less flexible and less efficient.
Since April 2025, solar curtailment alone has resulted in losses exceeding $26 million for power producers, highlighting the urgent need for solutions that can store excess clean energy and deploy it when required.
The whitepaper says that India should create a separate LDES policy as part of its National Framework for Promoting Energy Storage Systems. It also stresses the need for financial and regulatory actions, such as Viability Gap Funding (VGF) and clear deployment goals, to speed up adoption.
Key highlights from the report:
- Growing need for storage: The National Electricity Plan says that this will happen, as will more demand from electrification in different fields.
- Different ways to use technology: Includes ways to store chemical, thermal, mechanical, and electrochemical energy.
- Insights into global policy: Looks at successful frameworks from the UK, the US, Australia, and Italy, among other places.
- Roadmap for policy: To build a strong ecosystem, it focuses on targets, ways to get money, market design, and regulatory support.
The study was developed with contributions from LDES Council members, Indian energy stakeholders, and emerging startups in the storage sector. It has been presented to key government bodies, including NITI Aayog, the Ministry of Power, the Ministry of New and Renewable Energy, and the Solar Energy Corporation of India, aiming to support policy-level action for India’s clean energy transition.
