Solar EPC Tenders in India 2026: The Best Projects to Watch
Solar EPC Tenders in India 2026
Solar EPC Tenders in India 2026: Upcoming Projects Worth Watching
Quick Answer
Solar EPC tenders in India 2026 are dominated by NTPC Renewable Energy’s utility-scale packages, a steady stream of railway station solarisation under RESCO, and PSUs converting their own land and rooftops to solar.
The pipeline is large but tendering volume has softened year on year, so margins are tighter and selectivity matters more than bid volume. The two things separating winners in 2026 are locked-in ALMM-compliant module supply and a credential stack that clears the reference-plant bar.
India crossed roughly 150 GW of installed solar capacity in 2026, and renewables now account for a substantial share of the total power mix. For contractors, though, installed capacity is a vanity metric. What matters is how much work is actually being put out to bid, who is putting it out, and whether you can qualify for it — and on that front the picture in 2026 is more nuanced than the headline growth numbers suggest.
This guide covers the solar EPC tenders in India worth watching right now: which issuers are genuinely active, what the live pipeline looks like across utility-scale, balance-of-system, railway and captive segments, the qualification bars you will actually be measured against, and the single biggest execution risk facing EPC contractors this year.
Key Takeaways
- NTPC Renewable Energy is the most active issuer of large solar EPC packages, running several hundred-megawatt tenders across Rajasthan, Maharashtra, Karnataka and Andhra Pradesh.
- Tendering volume is down, not up. Roughly 5.4 GW was tendered by government agencies in Q2 2026 — lower than the previous quarter and materially lower year on year.
- Railway solarisation is the most accessible segment for mid-sized contractors, with all sixteen zonal railways mandated to solarise stations and yards.
- Qualification is capability-based, not just financial — expect cumulative commissioned capacity thresholds plus a reference plant with a minimum operating history.
- Cell sourcing is the year’s real risk. Domestic content rules extending to cells have raised genuine supply-crunch concerns.
- Bid security scales hard. Large utility packages have carried bid security in the tens of crores — a working-capital decision before it is a technical one.

What Solar EPC Tenders in India Cover
In a true EPC package, one contractor owns the whole build — design, procurement, construction and commissioning — and hands over a working plant. Scope in recent utility tenders has run from land grading, topographical survey and geotechnical investigation, through foundations and tracker-based mounting structures, to module supply, interconnection, transformers, protection systems, cabling and metering, plus grid-compliance facilitation and a multi-year comprehensive O&M period.
That breadth is what distinguishes solar EPC tenders in India from the adjacent structures you will see on the same portals. Knowing which one you are looking at determines your risk exposure before you read a single technical clause.
| Structure | What You Carry | Who It Suits |
|---|---|---|
| Full EPC | Everything including module supply; fixed price; LDs for delay | Established EPC firms with supply chain depth |
| Balance of System (BoS) | Everything except modules, which the owner supplies | Contractors wanting to avoid module price and ALMM risk |
| RESCO / developer mode | Capex, ownership and O&M; revenue via long-term PPA | Firms with balance sheet and appetite for 25-year assets |
| Supply-only | Modules, inverters or equipment against a delivery schedule | Manufacturers and authorised distributors |
| O&M contract | Operating an existing plant to availability guarantees | Service firms; steady annuity, thinner margins |
The BoS route deserves more attention than it gets. When the owner supplies modules, you shed both the module price exposure and the ALMM compliance headache in one move. In a year where cell sourcing is the dominant uncertainty, that transfer of risk is worth real money — and large BoS packages have been issued at multi-gigawatt scale.
The 2026 Market: Bigger Base, Tighter Pipeline
Here is the part most coverage skips: new tendering has slowed even as installed capacity climbs. Government agencies issued approximately 5.4 GW of solar capacity in the second quarter of 2026 — down modestly from the previous quarter and down more than a fifth compared with the same quarter a year earlier.
That does not make 2026 a bad year for solar EPC tenders in India. The absolute volume remains very large, and a substantial pipeline of already-awarded capacity still needs building. But it does change the strategy. A shrinking tender pool with a growing number of qualified bidders means more competition per package and thinner discovered prices. Firms that respond by bidding everything will win low-margin work and struggle to deliver it. The better response is to narrow — pick the segments where your credentials genuinely differentiate you and bid those properly.
Where the demand is actually coming from in 2026:
- CPSE-led utility build-out — NTPC REL and peers converting large sanctioned pipelines into EPC and BoS packages.
- Railway solarisation — a mandate across all zonal railways producing a continuous flow of small and mid-sized rooftop and land-based packages.
- PSU captive solar — thermal plants, mines, shipyards and industrial units solarising their own sites, often under RESCO.
- Rooftop under PM Surya Ghar — large central financial assistance already disbursed against an ambitious household target, driving installer demand.
- Storage-linked work — standalone BESS and solar-plus-storage auctions supported by viability gap funding, opening adjacent scope for EPC firms.
Upcoming Solar EPC Projects Worth Watching
The packages below are drawn from public reporting and illustrate the shape of the 2026 pipeline. Some are live, some have closed, and all are subject to amendment — treat them as a map of where the work is, and confirm any specific tender on the issuing authority’s portal before you act.
1
NTPC REL Utility-Scale EPC Packages
Utility EPCNTPC Renewable Energy has been issuing grid-connected solar EPC packages at serious scale through 2026 — among them a 550 MW project near Shimbhoo Ka Burj in Rajasthan, a 300 MW project near Nokhra in the same state, and 600 MW in Maharashtra structured as two blocks. Scope covers full design through commissioning including module supply, with comprehensive O&M attached.
Why watch: the deepest source of large EPC work in the country. Bid security on packages this size has run to tens of crores, so treat participation as a treasury decision first.
2
Balance-of-System Packages
BoS — lower riskAlongside full EPC, NTPC REL has tendered BoS supply for large blocks of grid-connected solar in Andhra Pradesh, and separately issued land and power-evacuation packages such as one facilitating 600 MW at Tumkur, Karnataka.
Why watch: owner-supplied modules mean no ALMM or module-price exposure. In 2026 that is arguably the most attractive risk profile available at scale.
3
Railway Station Solarisation (RESCO)
Most accessibleAll sixteen zonal railways are mandated to solarise stations, yards and administrative buildings. Southern Railway alone has run rooftop RESCO packages across Madurai division stations in the ten-crore range, plus land-based solar under developer mode, and other zones are issuing similar station-level work.
Why watch: package sizes that mid-tier contractors can realistically qualify for, a creditworthy offtaker, and a repeating cadence that rewards learning the format once.
4
PSU Captive and Mine-Site Solar
EmergingPublic sector undertakings are solarising their own footprints — NTPC Mining has sought expressions of interest for 50 MWp of solar across coal mines in Jharkhand and Chhattisgarh under RESCO with defined DC/AC ratio and CUF requirements, Central Electronics has tendered ground-mounted solar at a thermal plant site in Madhya Pradesh, and Cochin Shipyard has tendered rooftop capacity at its Kochi facility.
Why watch: EOI stages often carry no EMD, letting you signal interest and shape the eventual RFP terms at almost no cost.
5
Storage-Linked and Hybrid Work
Where it’s headingStandalone BESS auctions are drawing strong participation — Gujarat’s utility awarded a 450 MW/900 MWh standalone battery tranche in 2026 with viability gap funding support, at tariffs that came in within a rupee of each other between L1 and L2.
Why watch: tariffs that tight signal a maturing, brutally competitive segment. Enter with a genuine storage integration capability or not at all.

Who Issues Solar EPC Tenders in India
Knowing the issuer tells you the package size, the payment reliability and the documentation style before you open the document. Coverage across these bodies is what separates a complete view of solar EPC tenders in India from a partial one.
| Issuer | Typical Package | Where Published |
|---|---|---|
| NTPC REL / NGEL | 100–600 MW EPC, large BoS, module supply, O&M | NTPC and NGEL tender portals, eProcure, CPPP |
| SECI | Utility auctions, rooftop RESCO tranches, hybrid and storage | seci.co.in and its e-bidding system, CPPP, GeM |
| Indian Railways (16 zones) | Station rooftop and land-based solar, mostly RESCO | IREPS, zonal railway portals, CPPP |
| State DISCOMs / nodal agencies | Utility solar, agri-feeder, KUSUM, state rooftop programmes | State e-procurement portals and agency websites |
| PSUs (mining, defence, shipyards, refineries) | Captive ground-mount and rooftop, EOI-then-RFP route | GeM, CPPP, own procurement portals |
| Municipal and institutional bodies | Small rooftop, net-metered, often 100 kW to 5 MW | GeM, state portals |
Because the same project can surface on more than one of these channels, and amendments do not always appear on all of them simultaneously, single-portal monitoring reliably leaks opportunities. Our guide to the top government portals for tenders in India maps the landscape in full.
Qualification Criteria You Will Actually Face
Solar EPC qualification is capability-led, and the reference-plant test is where most aspiring bidders fall short. A recent large NTPC REL package required bidders to have designed, supplied and commissioned grid-connected solar plants of a cumulative 40 MWp or more, with at least one reference plant of 10 MWp or higher that had been in successful operation for at least six months — with an alternative qualification route for comparable industrial project execution.
That structure — cumulative capacity, plus a single anchor plant, plus a minimum operating history — is the pattern to plan around. It is why contractors serious about scaling in this market treat each completed project as a credential asset and document commissioning and performance rigorously from day one.
- Technical credentials — cumulative commissioned MWp, an anchor reference plant, and evidence of successful operation over a stated period.
- Financial capacity — turnover and net worth proportionate to contract value, with audited statements for the specified years.
- ALMM compliance — modules from the current approved list are effectively universal in government solar tenders; check the live list version before quoting.
- Quality certification — ISO 9001 is commonly required, particularly for PSU empanelment routes.
- Bid security — scaling with package size and running into tens of crores on the largest EPC tenders; see our EMD guide for instruments and MSME exemptions.
- Registration — portal registration on every relevant channel plus a valid Class 3 DSC, including GeM portal registration for the packages routed there.
The Risks That Decide Profitability
Winning a solar EPC package and profiting from one are different achievements. Fixed-price contracts with liquidated damages leave very little room between the two, and 2026 has a specific hazard worth naming.
Cell sourcing is the risk of the year. Domestic content requirements extending to solar cells have prompted industry warnings about a supply crunch and pricing pressure on compliant cells. In a full EPC contract you carry that entirely: a fixed bid price, a fixed commissioning date, and LDs if the modules are late. Lock supply agreements before you price the bid, not after you win it — or bid BoS packages instead and let the owner carry it.
- Corrigendum exposure — ALMM list versions, capacity and deadlines change mid-window; a missed amendment invalidates an otherwise strong bid. See our guide to corrigenda in solar tenders.
- Land and evacuation dependencies — where the owner supplies land or the pooling substation, your schedule depends on their delivery. Read the interface clauses and the relief they provide.
- O&M tail — multi-year comprehensive O&M is priced in the same bid. Under-costing it converts a profitable build into a loss-making decade.
- Aggressive scheduling — commissioning dates are contractual. Optimism at bid stage becomes LD exposure at execution.
- Price compression — with tendering volume down and bidder counts up, discovered prices are tight. Walking away is a legitimate strategy.
How to Bid on Solar EPC Tenders in India
Most disqualifications in this segment are procedural rather than technical. The sequence below is the discipline that keeps a capable firm in contention.
- Step 1 — Register everywhere the work appears, with a valid Class 3 DSC in the authorised signatory’s name.
- Step 2 — Screen against the reference-plant test first, before investing effort. If you cannot clear the anchor-plant requirement, consider a consortium or a smaller package.
- Step 3 — Confirm module and cell supply against the applicable ALMM list version, with written commitments on price and delivery.
- Step 4 — Attend the pre-bid meeting and raise queries on scope interfaces, land handover and evacuation responsibility — the clauses that later cause disputes.
- Step 5 — Build the technical bid with credential documents, ALMM and BIS compliance, methodology and key personnel; our technical vs financial bid guide covers the evaluation logic.
- Step 6 — Price the whole life, including the O&M tail, module escalation exposure and realistic mobilisation time.
- Step 7 — Arrange bid security early, since large packages tie up meaningful working capital for the bid validity period.
- Step 8 — Check for the latest corrigendum, then submit well before closing. Portal congestion in the final hour is a real and entirely avoidable cause of failure.

Frequently Asked Questions
What are solar EPC tenders in India?
Solar EPC tenders in India are contracts where a single contractor takes responsibility for the engineering, procurement and construction of a solar power plant — design, module and equipment supply, civil and electrical works, installation, testing and commissioning, usually with a multi-year O&M period attached. They are issued mainly by central PSUs such as NTPC Renewable Energy, state agencies and DISCOMs, Indian Railways, and public sector undertakings solarising their own sites.
Who issues the most solar EPC tenders in India?
NTPC Renewable Energy is currently the most prolific issuer of large utility-scale solar EPC packages, alongside balance-of-system and module supply tenders. Beyond it, the volume comes from SECI, state DISCOMs and nodal agencies, all sixteen zonal railways under the railway solarisation mandate, and PSUs procuring captive solar at their own plants and mines.
What qualification criteria do solar EPC tenders require?
Utility-scale packages typically require cumulative commissioned solar capacity as a threshold, with at least one reference plant of a specified size that has been operating successfully for a minimum period, plus turnover and net worth proportionate to the contract value. ALMM-listed modules are required across government solar tenders, and ISO 9001 certification is commonly asked for. The exact thresholds are set per tender and must be read from the document itself.
How much EMD do solar EPC tenders in India require?
EMD is set per tender and scales with contract value. Large utility-scale EPC packages of several hundred megawatts have carried bid security running into tens of crores of rupees, while rooftop and small ground-mount packages are far lower. MSMEs with valid Udyam registration can claim EMD exemptions where the tender permits. Always take the exact figure, instrument and validity from the specific tender.
Is the solar tender pipeline in India growing in 2026?
Installed capacity keeps climbing, but tendering volume has softened. Government agencies issued roughly 5.4 GW of solar tenders in the second quarter of 2026, down modestly from the previous quarter and down more sharply year on year. For EPC contractors that means a still-large but more competitive market, where selectivity matters more than volume of bids submitted.
What is the biggest execution risk in solar EPC contracts in 2026?
Module and cell sourcing. Domestic content rules extending to solar cells have raised industry concern about a supply crunch and pricing pressure on compliant cells. Since EPC contracts carry fixed prices and liquidated damages for delay, a contractor who has not locked in compliant supply before bidding is carrying both a cost and a schedule risk that the tender price may not cover.
Can a mid-sized contractor compete for solar EPC work?
Yes, but not against the largest utility packages initially. Railway station solarisation, PSU captive rooftop, municipal and institutional projects offer package sizes with achievable qualification bars and creditworthy counterparties. Build cumulative commissioned capacity and a documented anchor reference plant through that route, then step up to utility-scale packages once the credentials clear the threshold.
The Bottom Line
Solar EPC tenders in India remain one of the largest contracting opportunities in the country — but 2026 rewards focus rather than appetite. Tendering has tightened while the bidder pool has grown, which means the firms that do well are the ones that pick their segment, clear its qualification bar convincingly, and price with the module supply already locked.
Watch NTPC REL for scale, railway solarisation for accessibility, PSU captive work for early-stage influence through EOIs, and BoS packages whenever you want the volume without the cell risk. Then track the pipeline properly, because in a market this competitive the opportunity you never saw is the one that costs you most.
