NTPC Invites Bids for Largest Energy Storage Project with 9,000 MWh Capacity

The last date to submit the bids is June 16, 2023


NTPC Renewable Energy, a wholly-owned subsidiary of NTPC, has invited bids for interstate transmission system (ISTS)-connected energy storage projects of 9,000 MWh capacity with a minimum of 1,500 MW capacity to be installed anywhere in India.

The last date to submit the bids is June 16, 2023. Bids will be opened on the same day.

NTPC Renewable Energy intends to use the energy storage facility to meet its renewable RTC (round-the-clock)/peak power requirements complementing its wind and solar generation.

Bidders must submit ₹1.2 million (~$14,599)/MW of the quoted capacity as an earnest money deposit.

NTPC Renewable Energy will enter into an energy storage service agreement on an annual fixed charge basis with the selected bidders for 25 years.

The developer must set up the project on a build, own, and operate basis.

The power generated by any of the renewable projects of NTPC Renewable Energy will be used for the charging of the energy storage project. NTPC will utilize the energy storage facility on an on-demand basis, suited to its requirements during the peak and off-peak hours to meet its round-the-clock and peak power requirements.

The project size must be a minimum of 600 MWh with 100 MW (minimum) capacity. Bidders can quote capacities in multiples of 600 MWh for the storage component and multiples for 100 MW for the minimum capacity.

Projects under construction or not yet commissioned will be considered in case these projects are not already accepted under any other central or state programs.

Enhancement and augmentation of already commissioned projects, irrespective of their capacities, will not be considered eligible projects under this program.

Already commissioned projects will not be considered under this tender.

Any bidder from a country that shares a land border with India will be eligible to bid in this tender only if the bidder is registered with the competent authority.

However, the said registration requirement will not apply to bidders from those countries (even if it shares a land border with India) to which the Government of India has extended lines of credit or in which the Government of India is engaged in development projects.

Recently, Greenko Energies won the NTPC Renewable Energy’s auction to set ISTS-connected energy storage systems of 3,000 MWh capacity with a minimum of 500 MW capacity to be installed anywhere across India. Greenko won the entire capacity by quoting ₹2.79 million (~$33,985)/MWh/year.

Earlier, NTPC Renewable Energy had issued an invitation for bids for the design, engineering, manufacturing, supply, installation, and commissioning of a 250 MW/500 MWh grid-connected standalone battery energy storage system (BESS) near Fatehgarh-III ISTS substation in Rajasthan.
