TL;DR
India’s Solar Energy Corp. of India (SECI) has issued a tender for developing 1.2 GW of renewable energy projects with integrated storage. The projects will deliver 4,800 MWh of peak power daily and are part of India’s efforts to enhance grid stability and renewable capacity.
India’s Solar Energy Corp. of India (SECI) has officially invited bids for the development of 1.2 GW of renewable energy projects coupled with energy storage systems, aiming to supply 4,800 MWh of assured peak power daily. This initiative is part of India’s broader strategy to increase renewable capacity and improve grid stability through dispatchable clean energy.
SECI’s tender seeks developers to establish renewable energy facilities with integrated energy storage, capable of delivering 4,800 MWh of power during peak periods. The projects will connect to the interstate transmission system (ISTS) and are to be developed on a build-own-operate basis, with 25-year power purchase agreements (PPAs) signed with successful bidders.
Developers will be responsible for infrastructure including generation assets, storage systems, and transmission up to the delivery point. Land acquisition and grid connection are within the developer’s scope. Bids must range from a minimum of 50 MW to a maximum of 600 MW per project, with the total capacity awarded to any bidder capped at 600 MW.
Implications for India’s Renewable Energy Goals
This tender marks a significant step in India’s efforts to deploy dispatchable renewable energy, addressing grid stability and peak demand challenges. Integrating storage with renewable projects enhances reliability, making clean energy more viable for meeting the country’s growing electricity needs. The initiative aligns with India’s commitments to expand renewable capacity and reduce reliance on fossil fuels, potentially influencing regional renewable energy markets and investment trends.

India’s Renewable Capacity Expansion and Storage Integration
India has been rapidly increasing its renewable energy capacity, aiming to reach 500 GW by 2030. Recent policies have emphasized integrating energy storage to improve dispatchability and grid flexibility. This tender follows previous initiatives that have focused on solar and wind development, now emphasizing storage-backed projects to ensure power delivery during peak periods.
SECI has been a key player in India’s renewable procurement, with multiple tenders over recent years. The current call for 1.2 GW of projects with storage underscores the country’s focus on creating a resilient, flexible clean energy system capable of supporting its economic growth and climate commitments.
“This initiative could significantly enhance India’s ability to manage peak demand with renewable energy, reducing dependence on fossil fuel-based peaking plants.”

Key Questions
When are the bid submission deadlines?
The exact deadline has not yet been announced; interested developers should monitor SECI’s official notifications for updates.
Can projects be located anywhere in India?
Yes, projects may be developed anywhere in India, provided they meet the connectivity and co-location requirements specified in the tender.
What is the minimum capacity for bidding?
Developers must bid for a minimum of 50 MW capacity per project.
Will the projects include both solar and wind energy?
The tender specifies renewable energy projects connected to the ISTS; it does not specify the energy source, so solar, wind, or hybrid projects could qualify.
What are the key benefits of integrating storage in these projects?
Storage allows for dispatchable power during peak demand, enhances grid stability, and supports renewable energy integration by smoothing supply fluctuations.
