Large-Scale BESS Tender in India: 4 GW/16 GWh for Energy Security
The Solar Energy Corporation of India (SECI) has issued a significant tender for the development of standalone battery energy storage systems (BESS) with a total capacity of 4 GW and 16 GWh. These initiatives aim to provide on-demand energy supply and will be implemented across the Indian states of Rajasthan and Gujarat.
The tender is divided into two distinct packages. For Rajasthan, a capacity of 2.5 GW/10 GWh is designated, while Gujarat is allocated 1.5 GW/6 GWh. Prospective bidders have the option to participate in one or both packages, with only one bid permitted per package. Individual bids for Rajasthan must range from 50 MW/200 MWh to 625 MW/2,500 MWh. For Gujarat, the limits are set between 50 MW/200 MWh and 375 MW/1,500 MWh.
A crucial aspect of this tender is the requirement that at least 51% of the energy used for charging the batteries must originate from renewable sources. This underscores the focus on sustainability within the Indian energy sector. Additionally, "Make in India" requirements apply, mandating a minimum local content share in battery procurement. Developers are required to submit an auditor-certified declaration to confirm this local content share.
SECI anticipates making central financial assistance available, amounting to INR 15 lakh per MWh of BESS, totaling INR 2,400 crore for the full 16 GWh. Selected developers will be required to establish the projects on a build-own-operate (BOO) basis and supply the necessary charging power to the BESS. SECI will enter into a power purchase agreement (PPA) to supply the stored energy to various buying entities across India.
Bidders' responsibilities include identifying suitable land, project installation, ownership, and the complete operation and maintenance of the BESS systems. The buying entity will be responsible for discharging the stored energy, while the developer must ensure supply in accordance with the performance requirements specified in the tender. Developers who have already commissioned BESS projects or have projects under construction with untied capacity are eligible to participate.
The tender was launched on October 28, 2026, and the deadline for submitting bids in offline mode is November 23, 2026.
