NTPC Green Energy has invited bids for a 3,300 MWh battery energy storage system at the NTPC REL Khavda solar plant in Gujarat. The turnkey project comprises four blocks, includes 15 years of operation and maintenance, and specifies a 25-year design life. The source report does not state bid deadlines, project cost or an award date.
NTPC Green Energy Ltd. (NGEL) has invited bids for an engineering, procurement and construction package for a 3,300 MWh battery energy storage system at the NTPC REL Khavda solar plant in Gujarat. The tender sets out a four-block layout and requires the selected contractor to provide 15 years of operation and maintenance, making the procurement a substantial storage project linked to an existing solar site.
The Khavda system is divided into four blocks at PSS-1, according to Energy Storage’s October 12 report, similar to other battery energy storage systems. Three blocks are each rated at 300 MW/900 MWh; the fourth is rated at 200 MW/600 MWh. Together, those specifications total 1,100 MW of power capacity and 3,300 MWh of energy capacity, making the project relevant to broader grid-forming battery storage developments. MW describes the system’s output capacity, while MWh describes the amount of energy it can store.
NGEL is seeking a turnkey EPC package. The listed scope covers design and engineering, supply and transport, unloading and storage, installation, and commissioning of the grid-connected battery system. The successful bidder must also provide comprehensive O&M for 15 years, a key consideration in energy storage market planning. The tender sets a 25-year design life for the system, including its batteries, from commissioning, and says the offered batteries must be rated for at least 25 years under a single-cycle-per-day application.
The tender’s degradation assumptions are to be set out in the bidder’s proposal for daily single-cycle operation, the report says. The source does not give a project value, bidding deadline, expected commissioning date or the identity of any bidders. Those details should not be inferred from the stated capacity or design life.
Khavda Adds Long-Duration Storage
The tender seeks to pair a large battery system with the NTPC REL Khavda solar plant. Storage can absorb electricity when generation is available and deliver it later, potentially helping a grid make greater use of variable renewable output. The tender itself, however, does not specify how the system will be dispatched, what services it will provide or how much electricity it is expected to cycle each day beyond the single-cycle design basis.
The project’s scale is clear from its specified 1,100 MW power capacity and 3,300 MWh energy capacity. Its long service and maintenance requirements also make performance over time a central procurement issue: bidders must account for battery degradation while meeting the stated operating-life and design-life terms. The tender does not establish that the system has been awarded or built; those remain future steps.

Two NTPC Tenders, Separate Sites
The same report describes another procurement by NTPC Renewable Energy Ltd. (NTPC REL): an EPC tender for a 1 GW ground-mounted solar photovoltaic project at Kambadur in Anantapur, Andhra Pradesh. That project is proposed in two 500 MW blocks, with the package including solar module supply and three years of operation and maintenance after commissioning.
The solar tender and the Khavda battery tender involve different companies, locations and scopes. The Kambadur project is a separate solar development in Andhra Pradesh; the 3,300 MWh storage system is planned for the Khavda solar plant in Gujarat. The source reports both developments together but does not say the projects are contractually linked or share a schedule.
“The BESS package will be executed on a turnkey basis.”

Bid Dates and Award Still Unreported
The source report does not provide the submission deadline, tender value, bid evaluation timetable or the date NGEL expects to award the EPC contract. It also does not identify the battery chemistry, supplier requirements, project financing or planned commissioning date. The report confirms that bids have been invited, but does not say how many companies will participate or whether any contract has been awarded.
Performance will depend in part on bidder proposals for capacity degradation under daily single-cycle operation. The tender’s stated 25-year design life is a requirement, not evidence that the system has already demonstrated that lifespan. The source does not give detailed capacity-retention thresholds or operating forecasts.
Bids Must Define Delivery Terms
The next reported milestone is the submission and evaluation of bids for the Khavda turnkey EPC package. NGEL would then need to select a contractor and establish a delivery and commissioning schedule; no dates for those steps are included in the source material.
Further tender or award information should clarify pricing, construction timing and technical performance terms, including how bidders plan to meet the design-life and degradation requirements. Until those details emerge, the confirmed development is the launch of procurement—not a completed installation or an awarded contract.
Key Questions
How large is the Khavda battery project?
The tender is for 3,300 MWh of energy storage, divided into four blocks. Their combined specified power capacity is 1,100 MW.
Where will the battery system be installed?
It is planned for PSS-1 at the NTPC REL Khavda solar plant in Gujarat, according to the tender details reported by Energy Storage.
What is the required service and design life?
The selected contractor must provide 15 years of operation and maintenance. The tender specifies a 25-year design life from commissioning and says batteries must be rated for at least 25 years under a single-cycle-per-day application.
Has NTPC selected a contractor or set a completion date?
The source confirms that NGEL has invited bids, but does not report an award, bidding deadline or expected commissioning date.
Is the 1 GW Andhra Pradesh solar project part of the battery tender?
No connection is specified. The Kambadur solar project is a separate NTPC REL procurement in Andhra Pradesh; the battery tender is for the Khavda site in Gujarat.
