NTPC Limited has invited expression of interest (EoI) from Indian and global companies to set up 1,000 MWh of grid-connected battery energy storage systems (BESS) on the premises of its power projects across India.

Interested applicants will be invited to undertake projects at single or multiple NTPC stations to set up facilities and scalable models for further additional requirements.

The last date to submit the bids is August 10, 2021, and the bids will be opened on August 11.

NTPC is looking for a complete end-to-end solution from eligible applicants for the BESS facility, including storage project, power conversion system, the balance of project, battery management system, including software solution for optimized operation of BESS.

NTPC aims to pursue grid-scale BESS at an appropriately chosen power station of NTPC in due consultation with the Power System Operation Corporation (POSOCO) and the Ministry of Power to provide the Indian grid with a flexible storage system, test the ability of NTPC to integrate BESS into its future operational regime and simultaneously extend the facility for ancillary operations by POSOCO to enhance the reliability of the grid.

When deployed by NTPC, the grid-scale BESS will be available for participation in both primary and secondary frequency response services and enhance the availability and quality of reserves in the grid.

NTPC will utilize the response received through this tender to identify various technologies for applications, financial viability, and the best possible option of the BESS system for commercial returns and formulation of specifications for various systems required to execute demonstration or commercial projects.

To participate in the bidding process, the bidder should be a battery energy storage manufacturer and should have manufactured and supplied batteries for grid-connected BESS of cumulative capacity of 5 MW/5 MWh or higher.

Additionally, the bidder should have carried out work of grid-interactive BESS of a cumulative installed capacity of 5 MW/5 MWh.

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

Earlier, NTPC had tendered 25 MW of solar projects with BESS to be developed on the island of Andaman & Nicobar. The tender included an 8 MW solar PV project with BESS to be developed in Chidiyatapu in southern Andaman. The agency had also tendered a separate 17 MW solar project with BESS to be developed in the village of Manglutan in south Andaman.
