What Is PM KUSUM?
PM KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) is the Government of India’s flagship solar scheme for the agricultural sector. Launched in 2019 and revised in 2020, the scheme targets three distinct rural and agricultural use cases through three dedicated components.
Component A covers decentralised ground-mounted solar power plants of 500 kW to 2 MW capacity, set up on barren or fallow farmland. The plant owner sells power to the DISCOM at a feed-in tariff, converting non-productive land into a solar income source.
Component B provides standalone off-grid solar pumps of 0.5 HP to 7.5 HP, replacing diesel-powered pumps. Farmers receive complete pump systems including solar panels, controller, motor, and accessories sized to their irrigation needs.
Component C solarises existing grid-connected agricultural pumps. The farmer’s pump is supplemented or replaced by solar generation, with surplus power sold to the DISCOM at a feed-in tariff.
The scheme’s stated targets are 30,800 MW of total capacity, including 10,000 MW under Component A, 17.5 lakh standalone pumps under Component B, and 15 lakh grid-connected pump solarisations under Component C.
In the solar industry, PM KUSUM is the largest agricultural renewable energy programme globally by target capacity. It addresses the triple challenge of farmer income, diesel substitution, and DISCOM financial stress from subsidised agricultural power.
In the Indian context, PM KUSUM is critical because agriculture consumes roughly 20% of India’s electricity, much of it heavily subsidised or free. Solarising agricultural pumps reduces DISCOM subsidy burden while giving farmers reliable daytime power and additional income. Heaven Designs’ engineering breakdown of PM KUSUM covers the design and interconnection requirements behind each component in more technical depth.
Why PM KUSUM Matters
PM KUSUM addresses structural problems in India’s agricultural energy ecosystem.
Farmer Income Impact
- Eliminates diesel costs. A 5 HP diesel pump consuming 2–3 litres per hour costs Rs 150–200 per hour of operation. Solar pumps eliminate this entirely.
- Additional revenue from surplus power. Component C farmers can sell excess solar generation to DISCOMs at feed-in tariffs, creating a new income stream.
- Land lease income from Component A. Farmers earn Rs 1–3 lakh per acre annually by leasing barren land to a Component A solar developer.
DISCOM Financial Impact
- Reduces agricultural subsidy burden. Solarised pumps reduce the volume of free or subsidised power DISCOMs must supply to farmers.
- Defers infrastructure investment. Distributed solar plants reduce the need for new rural transmission and distribution capacity.
- Improves collection efficiency. Solar pump users pay for their systems upfront or through loans, reducing DISCOM receivables.
Environmental Impact
- Diesel displacement: Component B alone targets 17.5 lakh diesel pump replacements, avoiding millions of litres of diesel consumption annually.
- Carbon reduction: The full 30,800 MW target avoids an estimated 40+ million tonnes of CO₂ over the project life.
- Groundwater sustainability: Reliable daytime solar pumping enables better water management compared to erratic grid supply that often comes at night.
How PM KUSUM Works
Component A: Decentralised Solar Plants
- Land identification. Farmers or aggregators (cooperatives, FPOs) identify barren or fallow land suitable for solar installation.
- Developer selection. The farmer either develops the plant directly or leases land to a solar developer who handles financing, construction, and operation.
- Grid connection. The plant connects to the nearest 33 kV or 11 kV DISCOM substation through a dedicated feeder.
- Power sale. The plant sells electricity to the DISCOM at a feed-in tariff determined by the State Electricity Regulatory Commission (typically Rs 2.50–3.50/kWh).
- Revenue distribution. The farmer receives land lease income plus a share of generation revenue if structured as a partnership.
Capital cost for a 1 MW Component A project is approximately Rs 4.5–5.5 crore. Financing is available through PSU banks under priority sector lending at concessional rates.
Component B: Standalone Solar Pumps
- Application. The farmer applies through the State Nodal Agency with land records, existing pump details (if replacing), and Aadhaar.
- Eligibility verification. The SNA verifies land ownership, water source availability, and pump sizing.
- Supplier allotment. The pump is allotted from a panel of SNA-approved suppliers.
- Installation. The supplier installs the complete system: solar panels, controller, motor, pump, and accessories.
- Commissioning and subsidy release. After inspection, the central and state subsidies are disbursed, and the farmer pays their contribution.
Subsidy structure: 30% central CFA + 30% state subsidy = 60% total subsidy. Many states add another 20–30%, reducing the farmer’s share to 10–20%. Farmers replacing an existing diesel pump follow a slightly different documentation path — see how to file a Component B pump-replacement claim. QBits Energy’s overview of the KUSUM agricultural subsidy walks through how the central-plus-state stack compares with other rural solar subsidy routes.
Component C: Solarisation of Grid-Connected Pumps
Individual pump solarisation: A solar plant sized to the pump’s energy needs is installed at the farm. The farmer uses solar power during the day and grid power during off-hours. Surplus solar is exported to the DISCOM at a feed-in tariff.
Feeder-level solarisation: An entire agricultural feeder is solarised through a centralised solar plant. The plant supplies daytime power to all pumps on the feeder. This sub-model is cost-effective for DISCOMs because it reduces their cost of supplying subsidised agricultural electricity. See a worked example of Component C grid-tied pump solarisation for how the export metering is set up. Because the export approval and metering process differs by utility, Heaven Designs’ state-by-state DISCOM net metering process guide is a useful reference before applying.
Subsidy under Component C follows the same structure as Component B: 30% central + 30% state + farmer contribution.

Common Mistakes & Misconceptions
-
Applying without verifying land records. Land must be in the farmer’s name or with explicit owner consent.
- Avoid by: Obtaining a current land record extract before applying.
-
Mismatching pump capacity to water source. An oversized pump cannot extract more water than the aquifer provides.
- Avoid by: Conducting a hydrogeological survey before selecting pump size.
-
Choosing an unapproved supplier. Only SNA-panel suppliers qualify for subsidy.
- Avoid by: Verifying supplier panel status on the SNA portal before signing.
-
Skipping the feasibility step. Some sites have inadequate solar resource or insufficient water table.
- Avoid by: Allowing the SNA or vendor to conduct a proper site assessment.
-
Not budgeting for the farmer’s share. The 10–40% contribution can be Rs 50,000–2,00,000.
- Avoid by: Exploring bank loan options under priority sector lending before applying.
-
Forgetting state-specific add-on subsidies. Many states offer additional support that reduces farmer contribution further.
- Avoid by: Checking your state’s SNA website for current subsidy stacks.
-
Neglecting maintenance. Solar pumps need periodic panel cleaning and controller checks.
- Avoid by: Signing an AMC or training family members on basic maintenance.
-
Assuming Component A is passive income. Land lease agreements vary; some require active involvement.
- Avoid by: Reading the lease agreement carefully and understanding revenue-sharing terms.
-
Ignoring grid integration requirements for Component C. Net metering approval is essential for surplus export.
- Avoid by: Working with an experienced EPC that handles DISCOM coordination.
-
Expecting instant subsidy disbursement. Subsidy release follows commissioning and inspection, which takes time.
- Avoid by: Budgeting for the full farmer contribution upfront and treating subsidy as a reimbursement.
