India’s SECI issues tender for 500 MW/1000 MWh standalone battery storage systems

The state-owned Solar Energy Corporation of India Limited (SECI), has issued a tender for setting up 500 MW/1000 MWh standalone battery energy storage systems (BESS) in India, a government statement said, adding that this will help provide Discoms with storage facilities to be used on an “on-demand” basis.

The proposed projects will be installed in the vicinity of the Fatehgarh-III Grid-Substation of the ISTS network in the western state of Rajasthan. The buying entities will be offered the storage capacity to charge and discharge the same daily through renewable power, as per their energy shifting requirements.

According to the statement, the projects will be set up on a “build-own-operate” basis, with the connectivity and necessary permissions being under the scope of the project developer. Land for the projects will be provided by the CTU to the Developers on a right-to-use basis.

The SECI is the implementing agency of this tender and will be procuring capacity on behalf of the buying entities, charging a facilitation fee in the form of a trading margin, the statement said.

A unique feature of this tender is the composition of capacity offtake. Out of the total capacity being installed under the tender, 60% will be taken by SECI on behalf of the buying entities while the offtake of the remaining capacity will be the responsibility of the developers through third-party or market sale.

The tender marks the first tranche of the government’s immediate target of setting up 4000 MWh of battery storage capacity as part of achieving increased penetration of renewable energy in the national grid.
