Lakhs of diesel-powered agricultural pumps run across India, and for many small and marginal farmers, diesel fuel is the single largest input cost after seeds and fertiliser. PM KUSUM Component B was designed specifically to solve this, replacing standalone diesel pumps with solar pumps where no grid connection exists. The farmer pays 10% of the system cost upfront; the central and state governments jointly fund at least 60%, with an optional 30% bank loan covering the balance.
This guide covers the complete PM KUSUM Component B application process: who qualifies, what documents are needed, how to apply through each state’s implementing agency, what the real farmer contribution is by pump HP, and the most common reasons applications fail.
Scheme status, October 2026. PM-KUSUM’s sanctioned period ran to 31 March 2026. MNRE has allowed projects whose PPA was signed, or whose Notice to Proceed was issued, on or before 31 December 2025 to complete by 31 March 2027, and has said there will be no extension beyond that date (MNRE office memoranda of 28 March, 25 May and 28 September 2026, published on the PM-KUSUM national portal). MNRE has said the scheme’s committed liabilities will move into a successor scheme, PM-KUSUM 2.0, which it described in March 2026 as at the proposal stage. Before preparing a file, confirm with your state implementing agency whether any application window is actually open.
Direct answer. PM KUSUM Component B provides 30% central assistance (50% in North-Eastern, hill and island states) plus a state share of at least 30% for standalone solar agricultural pumps. Eligible farmers pay 10% upfront, approximately ₹13,000–₹40,000 for 2 to 7.5 HP pumps, with an optional loan for a further 30%. Applications go through the state implementing agency MNRE has named for Component B, not the PM Suryaghar portal. The PM KUSUM national portal is pmkusum.mnre.gov.in.
Component B is the most widely applicable part of PM KUSUM. If you have agricultural land, a water source, and no existing grid-connected pump for that field, you are likely to qualify when your state has an open sanctioned quantity.
What Is PM KUSUM Component B?
PM KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyaan) has three components. Component B is specifically for standalone solar pumps: systems that run independently without grid connection. These are the pumps that replace diesel engines on farms with borewells, open wells, farm ponds, or canal inlets.
Unlike Component C (which adds solar to existing grid-connected pumps), Component B serves farmers who have no electricity connection at all for their irrigation pump. The solar pump replaces the diesel or kerosene engine entirely.
The Ministry of New and Renewable Energy (MNRE) sets the benchmark cost for each pump capacity (HP). Central assistance is calculated on the MNRE benchmark cost or the tender cost, whichever is lower, so if a vendor charges more than that, the farmer pays the difference.
Component B Subsidy Breakdown
Who Is Eligible for Component B?
Eligibility for Component B is relatively broad. You qualify if you meet all of these:
- Indian farmer with agricultural land, owned or leased (with tenancy agreement)
- Valid water source on or near the land: borewell, open well, canal intake, farm pond, or check dam
- No existing grid-connected electricity connection for the pump on that field: this is the key eligibility gate
- Land records available (state-specific formats, see documents section)
- Aadhaar-linked bank account for DBT
MNRE’s guidelines give priority to small and marginal farmers and to farmers using micro irrigation; states may add categories such as SC/ST. New standalone pumps are not covered in dark or over-exploited groundwater zones, where only existing diesel pumps can be converted, and only with micro irrigation.
Farmers with an existing grid-connected pump should apply under Component C instead. Applying under the wrong component is a common rejection reason, see the PM KUSUM complete guide for Component C details.
Real Farmer Cost by Pump HP (2026)
MNRE publishes benchmark system costs, and central assistance is worked out on the benchmark or tender cost, whichever is lower. The figures below are typical market costs, not MNRE benchmarks; your agency’s tender rate decides the actual farmer share:
| Pump HP | Typical System Cost | Farmer’s 10% Share | Annual Diesel Saved |
|---|---|---|---|
| 2 HP | ₹1,30,000–₹1,50,000 | ₹13,000–₹15,000 | ₹35,000–₹50,000 |
| 3 HP | ₹1,80,000–₹2,10,000 | ₹18,000–₹21,000 | ₹55,000–₹75,000 |
| 5 HP | ₹2,50,000–₹3,00,000 | ₹25,000–₹30,000 | ₹85,000–₹1,15,000 |
| 7.5 HP | ₹3,40,000–₹4,00,000 | ₹34,000–₹40,000 | ₹1,20,000–₹1,60,000 |
| 10 HP | ₹4,50,000–₹5,20,000 | Above 10% (central assistance capped at the 7.5 HP level) | ₹1,60,000–₹2,10,000 |
Diesel savings calculated at ₹92–₹96/litre (mid-2026 national average), 8 to 10 hours/day irrigation season.
Pump size selection: MNRE’s guidelines say the pump size is chosen on the water table, the land covered and the irrigation need. Pumps above 7.5 HP are allowed, but central assistance stops at the 7.5 HP amount (up to 15 HP in North-Eastern and hill states, for up to 10% of installations). Farms with deep borewells usually need the larger sizes. Your implementing agency confirms the size during site verification.
💰 Real numbers
A Rajasthan farmer with a 5 HP diesel pump spending ₹90,000 per year on diesel will recover their entire ₹28,000 KUSUM contribution in under 4 months. The solar pump then runs free for 25 years, that's ₹22+ lakh in diesel savings over the system's life.
Documents Required for Component B Application
Documents are broadly consistent across states, with minor variations in land record formats:
| Document | Notes |
|---|---|
| Aadhaar card | Identity + DBT linkage, must match bank account |
| Land record (state-specific) | Gujarat: 7/12 Utara + 8A Khata; Rajasthan: Jamabandi; MP: Khasra/Khatoni; UP: Khatauniand Khasra |
| Bank account details | Aadhaar-seeded; passbook or cancelled cheque |
| Photograph | Passport size, recent |
| Water source proof | Borewell drilling completion report / groundwater authority permission (where applicable) |
| Tenancy agreement | Only for tenant farmers, plus landowner consent |
| Existing pump details | For Component C only; not needed for Component B |
For Gujarat specifically: 7/12 Utara (Satbara) and 8A Khata are the mandatory land records. Both are available online at the AnyROR portal (anyror.gujarat.gov.in). The KUSUM Gujarat GEDA guide covers the Gujarat-specific process in full detail.

Common Rejection Reasons (and How to Avoid Them)
-
1
Name mismatch between Aadhaar and land record, the most common rejection. Fix at the Tehsildar or Talati office before applying.
-
2
Existing grid connection on the same survey number, makes you ineligible for Component B. Apply under the Component C grid-tied pump scheme if you have a grid-connected pump on the same field.
-
3
Outdated land record, some states require land records issued within the last 6 to 12 months. Download fresh copies before applying.
-
4
Non-Aadhaar-seeded bank account, DBT requires Aadhaar linkage. Verify via NPCI and fix at your bank branch before submitting.
-
5
Water source not verified, some states require a groundwater department permit or borewell completion report. Check your state's requirements before applying.
-
6
Quota exhausted, MNRE allocates quantities to each state's implementing agency. If the sanctioned quantity is full, applications are waitlisted until a new allocation, which under current timelines depends on PM-KUSUM 2.0.
⚠️ Watch out
Unscrupulous agents sometimes collect "application fees" from farmers to file KUSUM applications. Any official fee is published by the state implementing agency, and the farmer contribution is paid only after you receive a demand letter. Never pay upfront to an agent claiming to "guarantee" selection.
What Happens After Installation
Once your solar pump is commissioned, you receive:
- 5 years of comprehensive maintenance from the empanelled vendor, with the pumping system guaranteed for at least 60 months against defects
- Commissioning certificate from the state nodal agency, keep this document carefully
- O&M support: check what your vendor includes for annual maintenance (cleaning, checks, minor repairs)
Solar pump panels require cleaning every 2 to 4 weeks during dry months to maintain output. The pump motor and controller are the components most needing attention, check for unusual vibrations or noise, and report issues to the vendor within the warranty period.
For ongoing performance benchmarks, refer to the diesel pump vs solar pump ROI comparison, which covers what generation you should expect by HP and season.

Frequently Asked Questions
What is the difference between KUSUM Component A, B, and C?
Component A allows farmers to lease land or install solar plants (500 kW–2 MW) and sell power to the DISCOM. Component B provides standalone solar pumps for off-grid irrigation, no existing pump or grid connection required. Component C solarises existing grid-connected pumps. Most farmers with diesel pumps apply under Component B.
Can a tenant farmer apply for PM KUSUM Component B?
Yes. Tenant farmers with a valid tenancy agreement, crop sharing deed or registered lease, are eligible. The tenancy agreement must be submitted along with the landowner’s written consent. The Aadhaar and bank account must be in the tenant farmer’s name for DBT.
How long does the KUSUM Component B application take?
There is no national fixed timeline. For sanctioned quantities, MNRE gives implementing agencies 24 months from sanction to complete installations, and a clean individual file often moves in a few months. Document issues extend this significantly. New applications depend on an open sanctioned quantity, which under current timelines means PM-KUSUM 2.0.
What happens if my state’s KUSUM quota is exhausted?
If your state’s MNRE allocation is fully utilised, your application is waitlisted until a new allocation. Whether a waitlisted application carries over is decided by the state agency, so ask. With PM-KUSUM’s sanctioned period over, new allocations depend on PM-KUSUM 2.0.
Is there a KUSUM application fee?
Any official application or registration fee is set and published by the state implementing agency; check its notice. The farmer’s share is paid only after the demand letter. “Processing fees” or “agent fees” collected by middlemen are unofficial and should be reported to the agency.
What pump HP should I choose for my farm?
MNRE does not fix HP by acreage; its guidelines say the size depends on the water table, land covered and irrigation need, and central assistance stops at the 7.5 HP amount in most states. As a rough planning guide from our field work: 2 to 3 HP for up to 2 acres with shallow borewells; 5 HP for 2 to 5 acres; 7.5 HP for 5 to 10 acres or medium-depth borewells; 10 HP for deep borewells. Your state agency field officer verifies and approves the HP during site inspection.
Can I choose my own vendor under KUSUM Component B?
In many states you can select from the implementing agency’s empanelled vendor list, and your selection must be confirmed with the agency before installation begins. Practice varies by state and round. Heaven Green Energy is on GEDA’s empanelled list.
