India has surpassed a key climate milestone by achieving 50% of its installed electricity capacity from non-fossil fuel sources, five years earlier than committed under its Nationally Determined Contributions.
As of October 31, 2025, the country’s non-fossil installed capacity stood at about 259 GW, supported by 31.2 GW of additions in the ongoing financial year.
Renewable Energy Implementing Agencies (REIAs) under MNRE—SECI, NTPC, NHPC and SJVN have issued 67,554 MW of Letters of Award since April 2023, with no cancellations after issuance.
States are simultaneously releasing their own procurement tenders, while additional renewable capacity is being developed through green energy open access and captive routes, ensuring that renewable expansion progresses across multiple channels rather than relying solely on centralised bids.
The falling cost of solar-plus storage solutions and the need for power during peak hours have driven procurers toward dispatchable renewable energy. Solar-plus storage systems are increasingly preferred over plain solar and even wind-solar hybrid models due to their reliability and flexibility.
In line with this shift, the government has encouraged REIAs to focus on solar with energy storage, peak-hour supply tenders, and firm and dispatchable renewable energy (FDRE). To aid PPA finalisation, States are being urged to comply with Renewable Consumption Obligations, while REIAs are aggregating demand before issuing tenders.
Regional workshops with major renewable-procuring States are helping address implementation challenges and expedite PPA signings.
The Central Electricity Authority (CEA) is planning transmission infrastructure in advance, based on renewable potential identified by MNRE. Transmission systems are being implemented in phases to optimise use and avoid overbuild.
Battery Energy Storage Systems (BESS) of 47.2 GW have been incorporated into the planning framework up to 2032. These storage systems will support peak shifting, reduce congestion, and improve utilisation of transmission networks.
New connectivity regulations also allow renewable projects to receive grid access during both solar and non-solar hours, enabling smoother integration of storage-backed renewable energy without requiring additional transmission lines.

Crossing the 50% non-fossil capacity mark ahead of time highlights India’s accelerating clean-energy momentum. With coordinated efforts across agencies, states and industry, growing preference for storage-integrated systems and proactive transmission planning, the country is well-positioned to scale renewable power deployment sharply in the years ahead.
