BESS Tenders India 2026: Battery Storage Projects You Shouldn’t Miss
BESS Tenders India 2026: Battery Storage Projects You Shouldn’t Miss
Quick Answer
BESS tenders India 2026 are running at scale across SECI, NTPC and state DISCOMs — standalone storage under VGF, solar-plus-storage, and increasingly four-hour systems for overnight grid balancing.
Around 102 GWh was tendered across roughly 69 tenders in 2025 alone. But cumulative commissioned storage stood near 758 MWh at the end of that year, so the real story is a large award book working through an 18 to 24 month build cycle — with tariffs compressing hard as PSUs enter.
India’s storage market has moved from pilot projects to industrial-scale procurement in about three years. The driver is the duck curve: solar generates at midday while demand peaks after sunset, and every gigawatt-hour of the storage needed to bridge that gap gets bought through a tender. That makes the BESS tenders India 2026 pipeline one of the largest single procurement waves in the country’s infrastructure history.
This guide is about the projects specifically — what has been tendered and awarded, what tariffs are actually being discovered, which firms are winning, and what the numbers do not tell you. If you need the fundamentals first, start with what a BESS tender is. If you want the bidding mechanics, VGF structure and qualification strategy, our complete BESS EPC guide covers that ground.
Key Takeaways
- Tendered volume dwarfs built volume — roughly 102 GWh tendered in 2025 against cumulative commissioned capacity near 758 MWh.
- NTPC issued the most storage tenders in 2025 by count, with SECI leading on tendered capacity.
- Four-hour systems are gaining ground, particularly in Uttar Pradesh, shifting procurement from peak shaving to overnight support.
- Tariffs have collapsed since 2022, and recent auctions have separated L1 from L2 by as little as one rupee.
- A specialist winner class has emerged distinct from the solar EPC mainstream — then PSUs entered and compressed margins further.
- Undersubscription is real. One SECI FDRE tender awarded roughly 0.2 GW against 2 GW offered.

Where BESS Tenders India 2026 Actually Stand
The gap between what has been tendered and what has been built is the most important number in this market. Around 69 storage tenders totalling roughly 102 GWh were floated during 2025. Against that, five projects totalling about 547 MWh were commissioned in the same year, bringing cumulative installed storage to roughly 758 MWh by year end.
That ratio looks alarming until you understand the timeline. A single BESS project runs roughly 18 to 24 months from award to commissioning, and the tendering wave only gathered pace after viability gap funding arrived in 2023. So the correct reading is not that nothing is happening — it is that a very large award book is currently working through construction, and the execution phase of BESS tenders India 2026 is about to become extremely busy.
What that means depending on where you sit:
- Developers — competition for new awards is intensifying faster than commissioning experience is accumulating.
- EPC contractors and integrators — the execution wave is the opportunity. Awarded projects need building, and few firms have deep commissioning track records yet.
- Equipment suppliers — demand is back-loaded against the award book, so the ordering surge follows awards by several quarters.
- New entrants — credentials are still forming in this segment, which is unusual and will not last.
Who Is Issuing the Volume
Central agencies get the attention, but state procurement carries comparable weight. During 2025, NTPC hosted the highest number of storage tenders with SECI close behind, while SECI led on total tendered capacity followed by UPPCL. Among states, Tamil Nadu led on tendering activity and Rajasthan led on converting awards into execution — a distinction worth noting, because a state that tenders enthusiastically and executes slowly is a different proposition from one that finishes what it starts.
| Issuer | Typical Structure | What to Expect |
|---|---|---|
| SECI | Standalone BESS under VGF, solar-plus-storage, FDRE | Aggregator model — SECI signs the PPA and passes power to DISCOMs |
| NTPC / NGEL | Standalone BESS, thermal-site storage, large EPC packages | Highest tender count; includes EPC-mode work suited to builders |
| GUVNL (Gujarat) | Standalone BESS in phased tranches with VGF | Regular cadence, tightly competed, capacity-charge tariffs |
| UPPCL (Uttar Pradesh) | Four-hour BESS at scale | Leading the shift to deeper-duration systems |
| Andhra Pradesh / Tamil Nadu | Large state storage programmes in packages | Programme-level tenders split into buildable packages |
| NHPC, NLC, PGCIL | Standalone and hybrid storage | Additional central-sector volume outside SECI and NTPC |
Battery Storage Projects You Shouldn’t Miss
The packages below illustrate the shape of the current pipeline. Several have closed or been awarded; they are included because the structure repeats and the next tranche will look similar. Confirm any live tender on the issuing authority’s portal before acting.
1
SECI Odisha — 125 MW/500 MWh Standalone
Standalone / VGFSix standalone BESS projects — five of 20 MW/80 MWh and one of 25 MW/100 MWh — sited inside identified state transmission substations at Padampur, New Bolangir, Bhatli, Basta, Narendrapur and Tentuli Khunti, on a build-own-operate basis with O&M running up to 15 years. VGF was capped at ₹18 lakh per MWh of awarded capacity.
Why it matters: the template for substation-sited distributed storage. Smaller blocks mean qualification bars a mid-tier developer can realistically clear.
2
SECI Kolimigundla — 600 MW/1,200 MWh
Large standaloneA single-site standalone grid-connected BESS at Kolimigundla in Nandyal district, Andhra Pradesh — among the larger individual storage procurements SECI has run.
Why it matters: single-location scale of this size demands supply chain depth most bidders do not have. Watch who qualifies; it maps the top tier.
3
Andhra Pradesh Programme — 1,000 MW/2,000 MWh
Package-basedA state programme broken into buildable packages, including a 150 MW/300 MWh design, supply, erection, testing and commissioning package at Kalikiri.
Why it matters: package structure is EPC-friendly — you build without carrying 15 years of asset ownership.
4
NTPC Green — 800 MW/3,200 MWh EPC
EPC modeA large four-hour BESS EPC package from NTPC Green Energy, alongside NTPC’s wider storage tendering that has included 250 MW/500 MWh across Madhya Pradesh and Maharashtra, thermal-site storage in Uttar Pradesh, and a long-duration flow battery project.
Why it matters: EPC mode with a PSU counterparty is the cleanest risk profile in storage — build, hand over, get paid.
5
GUVNL Phase-IX — 450 MW/900 MWh
Awarded 2026Gujarat’s standalone BESS tranche, issued in June 2026 and awarded in August to NLC India Renewables (275 MW) and Sun Drops Energia of the KP Group (175 MW), with VGF support at ₹18 lakh per MWh.
Why it matters: the winning tariffs differed by one rupee per MW per month. Read that as a warning about how little pricing room is left.
6
UPPCL — 375 MW/1,500 MWh Four-Hour
4-hour shiftAwarded in May 2026 to KCC Buildcon, Agastya Energy Industries and MKC Infrastructure, at tariffs in the region of ₹6.45 to ₹6.46 per kWh, as part of Uttar Pradesh’s adoption of deeper four-hour systems.
Why it matters: the winners are infrastructure contractors, not legacy energy names. This segment is still open to newcomers with execution capability.

Catch every BESS tender the day it publishes
Track BESS tenders India 2026 across SECI, NTPC, NHPC, NLC, PGCIL and every state DISCOM in one dashboard — filtered by capacity, duration and state, with corrigendum alerts so a spec change never costs you a bid.
How the Tenders Are Structured
Two structural choices determine whether a given tender suits you at all: ownership model and duration. Get these wrong and you will spend weeks pricing work you were never positioned to take.
| Model | What You Do | Revenue | Suits |
|---|---|---|---|
| Build-Own-Operate | Fund, build, own and operate for the contract term | Capacity or energy tariff over 12–15 years | Developers with balance sheet and debt access |
| EPC | Design, supply, erect, test, commission; hand over | Contract value plus O&M period | Contractors and system integrators |
| Supply | Deliver battery systems, PCS or BoP to spec | Order value | Manufacturers and authorised suppliers |
On duration, a two-hour system such as 250 MW/500 MWh targets the evening peak, while a four-hour system such as 375 MW/1,500 MWh supports deeper overnight balancing. Four-hour procurement needs roughly twice the battery for the same power rating, which changes capital cost, land footprint, thermal management and augmentation planning substantially. The drift toward four-hour tenders in BESS tenders India 2026 is one of the more consequential trends in the market, because it rewards firms that can finance and cool larger installations.
Tariffs Being Discovered in 2026
Storage tariffs have fallen dramatically since 2022, and the compression is still going. But there is a trap in comparing them, because Indian storage tenders use two different tariff formats that are not interchangeable.
- Capacity charge (₹/MW/month) — used in standalone auctions where the DISCOM pays for availability of the asset and supplies the charging energy. Gujarat’s 2026 tranche settled around ₹2.32 lakh per MW per month.
- Energy tariff (₹/kWh) — used where the developer delivers stored energy. Uttar Pradesh’s four-hour award discovered figures around ₹6.45 per kWh.
Comparing a capacity charge against an energy tariff without normalising for cycles, duration and who supplies charging power will produce a completely misleading picture. Always check which format the tender uses before benchmarking your bid against a reported number.
Read the L1–L2 spread, not just L1. When two winners in a major auction are separated by a single rupee, the market has priced out its own margin. If your cost base cannot reach within a whisker of the last discovered tariff, competing on price in that segment is not a strategy — find the packages with fewer qualified bidders instead.
Technical Standards That Gate Entry
Storage tenders screen on certification far more rigorously than solar tenders do, and non-compliance is not fixable at bid stage. These are the gates that decide whether your proposed system is even evaluable.
- IEC 62619 — battery system safety certification, effectively mandatory across Indian BESS procurement.
- IEC 62477 or equivalent — commonly required for power conversion systems.
- CERC grid connectivity standards — compliance with applicable grid code requirements for response and control.
- LFP chemistry — lithium iron phosphate dominates specifications for thermal stability and cycle life; alternative chemistries need justification.
- Round-trip efficiency and degradation — guaranteed values with measurement methodology, frequently amended by corrigendum.
- Augmentation obligations — the requirement to top up capacity as cells degrade, priced across the full contract term.
Augmentation is where storage bids quietly lose money. A guaranteed capacity over 12 to 15 years against a degrading asset means buying additional cells at future prices you cannot know. Bidders who model augmentation at today’s cell prices are underwriting a risk they have not priced. Treat it as a core commercial assumption, not an annexure.
Who Is Actually Winning
A distinct specialist class has emerged in storage, separate from the solar EPC mainstream. Firms including Pace Digitek, Oriana Power and TrueRE, Bondada Engineering, Stockwell Solar Services and Ecoren Energy have been among the more active winners across state and central tenders, while in the PSU segment NTPC Green Energy, Tata Power and POWERGRID have taken large-capacity awards on balance sheet strength and DISCOM relationships.
The competitive dynamic worth understanding is what PSU entry did to pricing. When entities with the lowest cost of capital in the market started bidding against independent developers, discovered tariffs compressed sharply. For a private bidder, that makes cost of capital — not engineering — the decisive variable in open competition. It is a strong argument for targeting EPC-mode packages, where you are paid to build rather than asked to out-finance a PSU.
The Risks Behind the Headline GWh
The pipeline numbers are real, but they are not a forecast of revenue. Several structural risks sit between a tender notice and a profitable project.
- Undersubscription and cancellation — a SECI peak-power FDRE tender saw roughly 0.2 GW awarded against 2 GW offered, and tariff adoption petitions have been rejected by regulators. An award is not a signed PPA.
- Bucket filling — quoting large capacity does not mean receiving it. In Gujarat’s 2026 tranche, one bidder quoted 410 MW and was awarded 175 MW. Model your economics at partial allocation.
- Cell supply and pricing — import dependence and evolving domestic content rules create both cost and schedule exposure across an 18 to 24 month build.
- Offtake and payment security — DISCOM financial health varies materially by state; check the payment security mechanism, not just the tariff.
- Corrigendum churn — storage specifications are still maturing, so dispatch profiles, efficiency and configuration change mid-window. See our guide to corrigenda.
- Commissioning inexperience — with limited commissioned capacity nationally, most bidders are promising delivery timelines they have not yet proven.

Frequently Asked Questions
How big is the BESS tender pipeline in India in 2026?
Very large on paper. Around 69 storage tenders totalling roughly 102 GWh were floated during 2025, and central plus state procurement through 2030 has been estimated in the tens of thousands of megawatt-hours. Commissioned capacity is far behind that: cumulative installed storage stood at roughly 758 MWh at the end of 2025. The gap is a timing gap rather than a failure, since a single project typically takes 18 to 24 months from award to commissioning.
Who issues the most BESS tenders in India?
NTPC hosted the highest number of storage tenders during 2025, with SECI close behind, while SECI led on tendered capacity. State procurement is substantial and in some years larger than central procurement, with UPPCL, GUVNL, Tamil Nadu, Andhra Pradesh and Rajasthan among the most active. Rajasthan has led on actually converting awards into execution.
What tariffs are BESS tenders discovering in 2026?
It depends on the tariff format. Standalone capacity-based auctions are settling in the region of ₹2.3 lakh per MW per month, as seen in Gujarat’s 450 MW/900 MWh award in 2026 where L1 and L2 were separated by a single rupee. Energy-based four-hour procurements have discovered figures around ₹6.45 per kWh in Uttar Pradesh. The two formats are not directly comparable, and storage tariffs have fallen dramatically since 2022.
What is the difference between 2-hour and 4-hour BESS tenders?
Duration describes how long the system can discharge at rated power. A 2-hour system such as 250 MW/500 MWh suits evening peak shaving, while a 4-hour system such as 375 MW/1,500 MWh supports deeper overnight grid balancing. Four-hour tenders require roughly twice the battery for the same power rating, which changes capital cost, land, thermal management and augmentation planning significantly.
What technical certifications do BESS tenders require?
IEC 62619 certification for the battery system is effectively mandatory across Indian BESS tenders, with IEC 62477 or equivalent commonly required for power conversion systems, alongside compliance with CERC grid connectivity standards. Lithium iron phosphate chemistry dominates specifications because of its thermal stability and cycle life. Confirm the exact standards and versions named in each tender document.
Do BESS tenders always get fully subscribed?
No, and this is an underrated signal. A SECI peak-power FDRE tender saw only about 0.2 GW awarded against 2 GW offered, and a Gujarat standalone auction in 2026 saw one bidder quote 410 MW but receive only 175 MW under bucket filling. Undersubscription usually reflects tariff caps, offtake risk or connectivity constraints rather than lack of interest, and it often precedes a corrigendum relaxing terms.
Can a contractor enter BESS without owning the asset?
Yes, and for most contractors it is the sensible route. EPC-mode packages — such as large four-hour BESS EPC tenders from NTPC Green Energy, or state programmes split into design-supply-erect-commission packages — pay you to build and hand over rather than requiring 12 to 15 years of ownership. You avoid tariff risk, offtake risk and augmentation liability entirely.
The Bottom Line
BESS tenders India 2026 offer genuine scale, but the easy money has already been competed away in the headline standalone auctions. When L1 and L2 are a rupee apart and PSUs are bidding their cost of capital, price competition in that segment is a losing game for most firms.
The opportunity sits slightly to the side: EPC-mode packages where you are paid to build, state programmes split into achievable blocks, substation-sited distributed storage with lower qualification bars, and the coming execution wave for the enormous award book now moving through construction. Price augmentation honestly, check which tariff format you are being measured on, and track the pipeline properly — in a market moving this fast, the tender you never saw is the one that costs you most.
