NTPC Invites Bids for 3,000 MWh of Energy Storage Systems

NTPC Renewable Energy, a wholly-owned subsidiary of NTPC Limited, has invited bids from developers to set up interstate transmission system (ISTS)-connected energy storage systems of 3,000 MWh capacity with 500 MW (minimum) capacity anywhere in India.

The last date to submit the bids is March 11, 2022. Bids will be opened on the same day.

Interested bidders will have to submit ₹1.2 million (~$16,083) per MW as an earnest money deposit.

NTPC Renewable Energy intends to avail energy storage facility to meet its round-the-clock (RTC) renewable energy requirement with a wind-solar profile under service model from ISTS-connected energy storage projects with a capacity of 3,000 MWh at any location in India.


The minimum project size requirement is 600 MWh with 100 MW (minimum) capacity. The bidders can quote capacities in the following manner:

  • 600 MWh with 100 MW (minimum) capacity
  • 1,200 MWh with 200 MW (minimum) capacity
  • 1,800 MWh with 300 MW (minimum) capacity
  • 2,400 MWh with 400 MW (minimum) capacity
  • 3,000 MWh with 500 MW (minimum) capacity

NTPC Renewable Energy will enter into an energy storage service agreement on an annual fixed charge basis with the selected bidders for 25 years based on the terms and conditions of the request for selection (RfS).

The projects will be developed on a build, own, and operate basis.

The renewable power generated from the project will be used to charge the energy storage project. NTPC Renewable Energy will utilize the energy storage facility on a demand basis, as required during the peak and off-peak hours, to meet its RTC requirements.

Already commissioned projects will not be considered under this bid. But projects under construction or not yet commissioned will be considered if they 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 eligible under this bid.

Last June, NTPC had invited expressions of interest from Indian and global companies to set up 1,000 MWh of grid-connected battery energy storage systems on the premises of its power projects across India.

Earlier, NTPC had invited bids to install a 4 MW ground-mounted solar project with a 1 MW/1 MWh battery energy storage system and induction-based cooking system at the NTPC Energy Technology Research Alliance facility in Greater Noida.
