SECI’s ISTS-XV Scheme For 1,200 MW Solar PV Power Projects With Energy Storage Systems In India

In a recent development, Solar Energy Corporation of India (SECI) has issued a Request for Selection (RfS) Document inviting Solar Power Developers to set up 1,200 MW ISTS-Connected Solar PV Power Projects with 600 MW/1,200 MWh Energy Storage Systems (ESS) in India. The initiative falls under the Tariff-Based Competitive Bidding (SECI-ISTS-XV) scheme.

Under this RfS, Solar Power Developers (SPDs) are tasked with establishing ISTS-connected Solar PV Power Projects with Energy Storage System (ESS), including the transmission network up to the Interconnection/ Delivery Point. The primary objective is to supply Solar Power to SECI, with SPDs responsible for land identification, installation, and ownership of the project, along with obtaining connectivity and necessary approvals and interconnection.

The projects selected under this scheme will deploy Solar Photovoltaic Technology, but the selection of projects would be technology agnostic. It is mandated that ESS of at least 0.5 MW/1 MWh capacity for 1 MW Project Capacity shall be installed as part of the Project. However, it is clarified that ESS charged using a source other than solar power would not qualify as solar power.

The selection process will involve e-bidding followed by e-Reverse Auction, with SPDs submitting a single bid offering a minimum quantum of Contracted Capacity of 50 MW and a maximum quantum of 600 MW. Projects shall be quoted in multiples of 10 MW only.

Project locations will be chosen by the Bidder/SPD at their discretion, with the ESS component being co-located with the Solar PV Power generating components or located separately under a single project.

Part Commencement of supply of power from the Project shall be accepted by SECI, subject to certain conditions, without altering the Scheduled Commencement of Supply Date (SCSD). In case of delay in the commencement of the supply of power beyond the SCSD, penalties will be imposed.

Successful Bidders will be required to submit a Performance Bank Guarantee (PBG) before signing the Power Purchase Agreement (PPA), with the validity period extending up to 12 months after the SCSD of the Project.

This initiative aims to accelerate the deployment of solar power projects with energy storage systems, contributing to India’s renewable energy goals and promoting sustainable energy solutions. It presents an opportunity for solar power developers to participate in the country’s clean energy transition while ensuring a reliable and efficient power supply.
