TL;DR
India’s Solar Energy Corp. of India (SECI) has announced a tender for 1.2 GW of renewable energy projects with energy storage. Successful bidders will develop projects on a build-own-operate basis, with 25-year power purchase agreements. This move aims to enhance grid stability and supply reliability.
India’s Solar Energy Corp. of India (SECI) has issued a tender for the development of 1.2 GW of renewable energy projects with integrated energy storage systems, aiming to supply dispatchable power during peak demand periods. This initiative is part of India’s broader efforts to enhance grid stability and expand renewable capacity, with successful bidders signing 25-year power purchase agreements (PPAs).
SECI’s tender invites developers to bid for projects totaling up to 600 MW each, with a minimum capacity of 50 MW per bid. The projects will be connected to the interstate transmission system (ISTS) and must include energy storage systems capable of providing 4,800 MWh of peak power daily. The projects will be developed on a build-own-operate basis, with land acquisition and grid connectivity responsibilities falling on the developers. The successful bidders will enter into long-term PPAs to supply renewable power to distribution companies and other buyers across India.
The tender specifies that renewable energy assets and storage systems must be co-located within each project, and the total capacity awarded to any single bidder or group is capped at 600 MW. The projects are intended to provide reliable, dispatchable renewable energy, reducing dependence on fossil fuels and supporting India’s clean energy targets.
Implications for India’s Renewable Energy Goals
This development marks a significant step in India’s renewable energy expansion, emphasizing dispatchable power that can meet peak demand and enhance grid stability. The integration of storage with large-scale renewable projects addresses intermittency issues, making renewables more reliable and attractive to grid operators. It also signals India’s commitment to investing in advanced renewable infrastructure, potentially influencing future policy and market dynamics.
