Tamil Nadu has farms that run on grid pumps and diesel, so PM-KUSUM is a real market for solar EPCs here. But you cannot just sell a panel — you win tenders run by the state. This guide maps how PM-KUSUM works in Tamil Nadu so an EPC knows who to register with, where tenders appear, and which numbers to double-check before bidding.
Who runs PM-KUSUM in Tamil Nadu
In Tamil Nadu, TEDA — the Tamil Nadu Energy Development Agency — is the state nodal agency (SNA) for PM-KUSUM, and TANGEDCO, the state DISCOM, handles the grid side. TEDA runs empanelment and tenders. TANGEDCO owns the feeders and meters that Component C touches.
What each body does
- TEDA publishes tenders, empanels vendors, and releases the state subsidy share.
- TANGEDCO provides feeder data, grid connection and the agricultural-pump load that Component C solarises.
- MNRE sets the central scheme rules, the technical spec and the central subsidy share.
These roles can shift between orders, and sometimes a separate cell handles a component. Always verify the live roles on teda.in and pmkusum.tn.gov.in / with the SNA at publish before you build a bid plan.
Which PM-KUSUM components run in Tamil Nadu
Tamil Nadu can run several PM-KUSUM components, but not all are open or funded at once. Read the live order to see which the state is pushing this cycle.
The components in plain words
- Component B — new standalone solar pumps for farms with no grid pump.
- Component C1 — solarising an existing individual grid pump.
- Component C2 — feeder-level solarisation, where one solar plant powers a whole agricultural feeder of pumps.
- Component A — small grid-connected plants on barren or farm land.
For Tamil Nadu, Component C2 feeder solarisation is often the bigger volume play because TANGEDCO runs many agricultural feeders. To see how individual and feeder routes differ, read our Component C feeder solarisation guide. Which components are live changes — verify on teda.in and pmkusum.tn.gov.in / with the SNA at publish.
How to empanel and register with TEDA
To bid in Tamil Nadu, an EPC first gets empanelled with TEDA as a PM-KUSUM vendor. Empanelment is a one-time qualification; tenders come after. The exact steps below are estimates to verify.
The empanelment steps (estimate — verify)
- Watch teda.in and pmkusum.tn.gov.in for the vendor empanelment notice.
- Submit firm documents — PAN, GST, incorporation proof and Udyam/MSME.
- Submit financial proof — audited accounts, net worth and turnover.
- Submit experience proof — solar pump or plant work done, with capacity.
- Pay the application or processing fee the notice sets.
TEDA then publishes an empanelled-vendor list. Only listed firms can bid in the matching tenders. The fees, turnover floor and experience clauses are tender-specific estimates to verify on teda.in and pmkusum.tn.gov.in / with the SNA at publish. Our empanelment process guide covers the general flow across states.
Where TN PM-KUSUM tenders are published
PM-KUSUM tenders in Tamil Nadu are published by TEDA, usually on its e-procurement portal and through tender notices on pmkusum.tn.gov.in and teda.in. TANGEDCO may publish feeder details for Component C.
Where to watch
- TEDA e-procurement — the formal tender uploads and bid forms (verify the exact portal).
- pmkusum.tn.gov.in — the state PM-KUSUM portal with notices and updates (verify).
- TANGEDCO — feeder-level data and grid details for Component C.
Set a routine to check these weekly, because windows are short and EMD has to be ready. The exact tender source and dates are estimates to verify on teda.in and pmkusum.tn.gov.in / with the SNA at publish.
TN subsidy split — an estimate to verify
The PM-KUSUM subsidy in Tamil Nadu is commonly described as roughly 30% central + 30% state + 40% farmer, but the exact split changes per component and order. We treat every percentage here as an estimate, not a promise.
How the money usually flows
The central share comes through MNRE. The state share comes through TEDA. The farmer pays the balance, often with a bank loan. For feeder solarisation the structure can differ, and some orders adjust the state share. Read the live order — the state subsidy stacking map shows how central and state shares combine. Verify the live subsidy split on teda.in and pmkusum.tn.gov.in / with the SNA at publish.
Pump sizes and HP in Tamil Nadu
PM-KUSUM in Tamil Nadu typically covers solar pumps from about 3 HP up to 7.5 HP, and sometimes 10 HP, for Component B, following the MNRE size bands. The HP allowed and the subsidy per size depend on the tender.
Picking the right size
The farm's water table, bore depth and crop set the right HP. A deeper bore needs a higher-HP pump, which costs more and shifts the subsidy maths. Use our solar pump cost by HP benchmark to sanity-check your quote against typical prices. The exact HP bands and per-size subsidy are estimates to verify on teda.in and pmkusum.tn.gov.in / with the SNA at publish.
DCR, ALMM and the MNRE spec
Every PM-KUSUM bid in Tamil Nadu must meet the MNRE technical specification, plus the content rules — DCR (domestic content) and ALMM (the approved models list). These rules decide which modules and parts you may supply.
What this means for your bid
- MNRE spec — modules, motor, pump and the universal solar pump controller (USPC) must meet the rated values.
- DCR — cells and modules may need to be Indian-made (verify the current rule).
- ALMM — modules must come from the approved list (verify the live list).
- Test reports — BIS or IEC reports back every datasheet.
Pick make and model early so your datasheets match the annexure exactly. The spec and content rules change over time, so verify on teda.in and pmkusum.tn.gov.in and the latest MNRE order / with the SNA at publish.
EMD, PBG and the 5-year O&M
Two money items shape a TN PM-KUSUM bid: the EMD you pay to bid, and the PBG you post if you win. After that comes the 5-year O&M you must service.
The commitments in order
- EMD (earnest money deposit) — a refundable security with the bid; no valid EMD means rejection (amount set per tender — verify).
- PBG (performance bank guarantee) — held through the contract to back your delivery (amount and term per tender — verify).
- 5-year O&M — most PM-KUSUM contracts make the EPC service the pump for five years, which ties up cash and field time.
Price the five-year service into your bid, not just the supply. Our 5-year AMC and O&M guide breaks down the real cost. The EMD, PBG and O&M terms are tender-specific estimates to verify on teda.in and pmkusum.tn.gov.in / with the SNA at publish.
Common pitfalls for TN EPCs
Most Tamil Nadu bids fail on avoidable errors, not price. Watch these before you submit.
The repeat offenders
- Bidding before empanelment — you must be on the TEDA vendor list first.
- Missing or invalid EMD — the bid is rejected before price is read.
- Off-spec datasheets — ratings that miss the MNRE annexure or ALMM list.
- Ignoring TANGEDCO feeder data — Component C bids need the real feeder load.
- Underpricing the 5-year O&M — the service cost eats the margin later.
- Trusting old numbers — TN slabs, HP bands and subsidy shift; re-verify each cycle.
