A subsidiary of India’s biggest state-owned power generation company NTPC has invited bids to deploy battery storage at a large-scale renewable energy park in Gujarat.
NTPC Renewable Energy issued an invitation for bids (IFB) on 25 November for battery energy storage system (BESS) projects with minimum 250kW output and 1,200kWh capacity to aid solar-powered construction at the site.

Systems would be deployed at the company’s Khavda Renewable Energy Park (Khavda RE Park) in the state of Gujarat, where NTPC Renewable Energy’s plans include a 1,200MWh solar PV power plant, which it is also presently tendering for.
Winning bidders would be responsible for design, engineering, manufacturing, supply and logistics, installation, testing and commissioning of a standalone battery system.
The 250kW/1,200kWh nameplate output and capacity must be available for at least three years from commissioning and providers will be responsible for operations and maintenance (O&M) activities for three years.
NTPC Renewable Energy has certain specific requirements for system equipment and configuration, for the project or projects to deliver various applications.
Power conversion systems (PCS) must have 250kW capacity and be capable of performing black start functions for bidirectional inversion and/or charging of batteries, as well as provide voltage reference for solar inverters.
The BESS will be coupled with solar PV at the AC output bus and be capable of standalone operation off-grid in island mode, continuing to deliver load to motors and other heavy equipment.
Potential bidders have until 20 December to download bidding documents and until 9 January to submit techno-commercial and price bids.
NTPC is looking for companies with a proven track record in BESS projects of a similar scale, with the company to finance projects from its own resources.
It’s the latest energy storage tender from NTPC or its subsidiaries. At the beginning of November, the group launched its first long-duration energy storage (LDES) tender, seeking expressions of interest (EOI) in delivering projects in the range of 1MW to 6MW with eight-hour duration of storage (8MWh to 48MWh).
A few weeks before that, NTPC Vidyut Vyapar Nigam Ltd (NVVN), a power trading subsidiary, launched a tender for projects that could deliver “round-the-clock” renewable energy.
The parent company meanwhile launched an ongoing 250MW/500MWh battery storage solicitation earlier this year. As a group, NTPC is targeting for 30% of its energy generation to come from renewable sources by 2032.
Also in Gujarat, the state’s electricity board launched a tender for 500MW/1,000MWh of BESS in August.
