A farmer in Gujarat with 5 acres of barren land 4 km from a 33 kV substation can install a 1 MW solar plant, sign a 25-year PPA with the DISCOM, earn ₹3–4 Lakh per year in guaranteed lease income, and get up to 30% Central Financial Assistance — all under a single government scheme. That scheme is PM-KUSUM Component A, and it is one of the most underutilized opportunities in India’s solar buildout.
Direct answer. PM-KUSUM Component A is the decentralized solar plant sub-scheme under the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan. It enables individual farmers, cooperatives, FPOs, Water User Associations, and panchayats to install 500 kW to 2 MW grid-connected solar plants on agricultural land within 5 km of a 33 kV or higher substation. The DISCOM buys all power at a fixed levelized tariff for 25 years, with 30% Central Financial Assistance and 30% state subsidy available for eligible applicants. The CUF requirement of at least 19% for 2 consecutive months determines CFA disbursement.
This guide covers every stage of a Component A project in sequence: eligibility check, site assessment, application process, bidding mechanics, PPA terms, design optimization to meet the 19% CUF threshold, and the post-execution maintenance steps that protect your investment over the 25-year PPA horizon. We also introduce the Component A Readiness Score — a five-point checklist Heaven Designs engineers use before accepting any PM-KUSUM Component A design brief.
Who Is Eligible for PM-KUSUM Component A?
Eligibility is defined in the MNRE guidelines and is deliberately broad to maximize farmer participation. The following entities can apply as Renewable Power Generators (RPGs) under Component A:
- Individual farmers (sole owner or joint owners of the land parcel)
- Farmer Producer Organizations (FPOs) registered under the Companies Act 2013
- Water User Associations (WUAs) under state irrigation departments
- Cooperatives registered under state cooperative society acts
- Panchayat bodies at the gram panchayat or taluka level
- Companies or entrepreneurs who have entered into a land lease agreement with a farmer for the specific purpose of deploying a solar project
For the last category — companies or entrepreneurs on leased land — the key documentation requirement is a valid land lease agreement between the landowner (farmer) and the RPG (company/entrepreneur), executed on stamp paper with terms agreed by both parties. The lease duration must cover at least the 25-year PPA period.
Definition. Central Financial Assistance (CFA) under PM-KUSUM Component A is a direct subsidy from the Ministry of New and Renewable Energy, equal to 30% of the benchmark cost of the solar plant. State governments typically match this with an additional 30% state subsidy. The remaining 40% is the RPG's own contribution — typically financed through bank loans at 70% debt + 30% equity. CFA disbursement is conditional on the plant achieving a Capacity Utilization Factor of at least 19% for 2 consecutive months from commissioning.
Documents required at the application stage:
| Document | Who provides it | Notes |
|---|---|---|
| Aadhaar card (and/or PAN) | Applicant | For KYC verification |
| Land ownership proof | Landowner | State-specific format (Gujarat: 7/12 extract; Rajasthan: Jamabandi; MP: B1 Khasra) |
| Land lease agreement (if RPG ≠ landowner) | Both parties | Must be on stamp paper; minimum 25-year duration |
| EMD (₹1 Lakh/MW) | RPG | Bank guarantee from scheduled commercial bank |
| Grid connectivity feasibility confirmation | DISCOM/RPG | Confirms substation has available capacity at desired voltage level |
Land Requirements and Site Selection Criteria
Component A is specifically designed for land within 5 km of a grid substation — not because 5 km is an engineering limit, but because the cost of the sub-transmission line connecting the solar plant to the substation is borne by the RPG. Beyond 5 km, line cost typically erodes project viability.
Land requirement by system capacity:
| System Capacity | Approx. Land Required | Notes |
|---|---|---|
| 500 kW | 2.0–2.5 acres | Fixed tilt; south-facing; standard ground clearance |
| 1 MW | 4.0–5.0 acres | Includes access roads and perimeter fence |
| 2 MW | 8.0–10.0 acres | Access road width and internal cable trench must be planned |
All categories of land are eligible: barren, fallow, marshy, pasture, or cultivable land. The guidelines do not require the land to be classified as “wasteland” — even productive agricultural land can host a solar project under Component A, though the farmer must weigh foregone agricultural income against lease income.
Field tip. Substation capacity check is the first step, not the last. Many rural substations in India operate at 80–95% capacity utilization during peak agricultural season. A 1 MW solar plant feeding into an already-loaded 33/11 kV substation will face curtailment during peak hours — directly reducing CUF and risking failure to meet the 19% minimum. Always request the DISCOM's published substation-wise available capacity data before finalizing land selection.
The Component A Readiness Score: A Pre-Application Framework
Before an RPG submits an application, five checks determine whether the project can achieve the 19% CUF threshold and meet PPA commissioning timelines. The Component A Readiness Score assigns a pass/fail to each check — a single failure means the project needs site change or design revision before proceeding.
Solar Irradiance Check
Run a preliminary GHI assessment using Meteonorm or Solargis data for the specific latitude/longitude. Sites with GHI above 5.0 kWh/m²/day reliably achieve 19%+ CUF with standard fixed-tilt design. Sites below 4.5 kWh/m²/day in cloud-prone zones (Assam, Kerala) may require tracker configuration or above-average system design to meet the threshold.
Substation Capacity Confirmation
Verify available feeder capacity at the target substation with the DISCOM. The application fee of ₹5,000/MW is non-refundable — submitting without confirmed grid capacity wastes application cost and risks withdrawal penalty (which forfeit the ₹1 Lakh/MW EMD after LoA issuance).
Land Title Clarity
Confirm that the land records are clear (no encumbrances, disputes, or government acquisition proceedings). For leased land, verify the landowner has unencumbered title. Disputed land title is the most common cause of project delay post-LoA issuance.
Shadow Obstacle Assessment
Identify trees, buildings, transmission lines, and other obstacles within 100 m of the proposed panel area. A site with significant shading in the morning or afternoon hours that is not accounted for in the yield model can reduce actual CUF below the 19% threshold, triggering CFA withholding. A drone survey capturing obstacle heights eliminates this risk.
Commissioning Timeline Feasibility
Component A guidelines set a commissioning deadline from the date of LoA issuance. Delays beyond the stipulated timeline trigger PBG encashment penalties. Confirm that EPC availability, module procurement lead times, and grid connection installation timelines can be met within the deadline. In practice, 12–18 months from LoA to commissioning is a reasonable target for a 1 MW project.
Application Process and Bidding Mechanics
The application process for Component A varies by state — MNRE has published model procedures, but each state DISCOM implements its own version. The common steps are:
Step 1 — Apply to DISCOM: Submit your EOI (Expression of Interest) and pay the application fee of ₹5,000/MW (non-refundable). Include land ownership proof, Aadhaar, and EMD bank guarantee of ₹1 Lakh/MW.
Step 2 — Capacity Check: The DISCOM publishes substation-wise available capacity. If total applications for a substation are within available capacity, a Letter of Award (LoA) is issued on a first-come, first-served basis at the pre-fixed levelized tariff.
Step 3 — Bidding (if oversubscribed): If applications exceed available capacity at a given substation, the DISCOM conducts a competitive bidding process:
- Closed bid: All eligible applicants submit sealed tariff quotes simultaneously. The lowest bid wins, followed by the next lowest, until capacity is filled. All winners receive an LoA at their respective bid tariff.
- E-reverse auction: An online descending price auction where bidders reduce their quoted tariff until the lowest offer clears the available capacity.
In both cases, the bid tariff is capped at the pre-fixed levelized rate — bidders compete downward from that ceiling. The pre-fixed rate is set by the SERC and published in the DISCOM tender documents.
Watch out. Withdrawing your application after placing your bid — or failing to sign the PPA within 2 months of LoA issuance — results in forfeiture of the full EMD bank guarantee (₹1 Lakh/MW). For a 2 MW project, that is ₹2 Lakh in immediate penalty. The PBG (which replaces the EMD after LoA) is also forfeited if commissioning deadlines are missed. Every delay milestone must be tracked rigorously from day one of the LoA.
Power Purchase Agreement: 25-Year Terms You Must Understand
The PPA under Component A is between you (the RPG) and the DISCOM, for a term of 25 years from the Commercial Operation Date (COD). Key terms from the MNRE model PPA (Annexure II):
| PPA Term | Detail |
|---|---|
| Duration | 25 years from COD; extendable by mutual agreement |
| Tariff | Pre-fixed levelized rate set by SERC; or bid-determined rate |
| Must-run obligation | DISCOM must purchase all power up to contracted capacity — no curtailment without compensation |
| PPA signing deadline | 2 months from LoA issuance |
| Commissioning deadline | Defined in LoA (typically 12–18 months); delays trigger PBG encashment |
| Payment security | DISCOM must establish Escrow Arrangement for payment security |
| CUF minimum | 19% for 2 consecutive months — required to receive 100% of CFA |
| Post-PPA operation | RPG may continue operating beyond 25 years if land lease allows |
The must-run obligation is a critical protection for RPGs — it means the DISCOM cannot curtail your plant during high-generation hours without paying a compensation tariff. This protection, combined with the fixed offtake tariff, makes Component A one of the most revenue-secure solar models available to small developers in India.
MNRE’s PM-KUSUM Component A portal provides state-specific application procedures and the current pre-fixed levelized tariff rates. State portals vary significantly in their workflow — always download the state-specific guidelines before beginning the application process.
Pre-Execution Design: How to Guarantee 19% CUF
The 19% CUF threshold for 2 consecutive months is the critical performance gate for CFA disbursement under PM-KUSUM Component A. Achieving it reliably over 25 years — not just in the first commissioning months — requires engineering design that accounts for all system loss factors from day one.
The CUF calculation: CUF (%) = Annual Energy Generated (kWh) / [Installed Capacity (kW) × 8,760 hours] × 100
According to IRENA’s Renewable Power Generation Costs 2023, the global benchmark LCOE for utility-scale solar PV reached $0.044/kWh — lower than any fossil fuel alternative. India’s decentralized PM-KUSUM Component A tariffs of ₹3–4.5/kWh are fully competitive with this benchmark even at small-scale 500 kW–2 MW project sizes when CFA and state subsidies are factored in.
For a 1,000 kW (1 MW) plant to achieve 19% CUF: it must generate at least 1,664,400 kWh (16.64 lakh kWh) annually. At a Performance Ratio of 80% (a reasonable target for a well-designed fixed-tilt system in central India), the required GHI is approximately 4.8 kWh/m²/day — easily achievable in Rajasthan, Gujarat, Madhya Pradesh, and most of peninsular India.
The four design inputs that directly control whether you hit 19%+:
1. Accurate irradiance data and PVsyst simulation
Use Meteonorm 8.x or Solargis TMY data for the specific site coordinates. Generic state-level irradiance averages can under- or overestimate site GHI by 5–10%, which translates directly into CUF error. A bankable PVsyst report built on verified meteorological data gives you a reliable P50 CUF estimate before the project is committed.
2. Shadow-free layout with correct row spacing
The General Arrangement (GA) layout must place solar rows at a spacing that prevents inter-row shading during the design minimum sun angle — typically the December 21 sunrise and sunset hours for south-facing Indian installations. Incorrect row spacing causes shading losses of 3–8% annually, which can be the difference between 19.5% and 17% CUF on a marginal irradiance site.
3. Correct string sizing and MPPT range design
Temperature-corrected Voc must stay below the inverter’s maximum DC input voltage at the lowest expected ambient temperature (typically December–January nights in northern India). String sizing using module temperature coefficients per the site’s recorded minimum temperature prevents overvoltage shutdowns that cut generation during winter mornings — precisely when generation hours are already limited.
4. Optimized tilt angle
For fixed-tilt installations, the optimal tilt angle for maximum annual yield is approximately equal to site latitude minus 5–10° for high-irradiance Indian sites. A 1 MW plant in Gujarat (latitude 22°N) with tilt set at 15° instead of the optimal 18–20° loses approximately 1.5–2% of annual yield — roughly 25,000–33,000 kWh — which narrows the CUF margin.

After the pre-design PVsyst simulation confirms the site is viable and layout is optimized, the detailed design phase produces the engineering drawings required for EPC execution, DISCOM metering approval, and CEIG clearance.
Structural design deliverables:
- Mounting structure system selection based on Soil Bearing Capacity (SBC) report — helical piles, earth screws, driven piles, or ballasted foundations depending on soil type and wind zone
- Structural analysis using STAAD Pro per IS 875 Part 3 wind load for the applicable wind zone. For PM-KUSUM sites in high wind zones (Gujarat coastal, Rajasthan west), wind load analysis is critical — mounting structures that fail this check create “flying kite” risk during summer storm season
- Optimal tilt angle calculation considering land slope and row spacing
Electrical design deliverables:
- Single Line Diagram (SLD) with protection relay settings, inverter configuration, metering arrangement, and grid connection scheme
- AC/DC cable sizing per IS 1554 Part 1 with voltage drop calculations — total DC string voltage drop must remain below 1.5%
- Earthing and lightning protection design per IS 3043, with earth electrode test pit locations shown on drawing
- HT side design: 11 kV or 33 kV metering panel, protection relay settings, APFC panel if required by DISCOM
The HT side connection to the substation is the RPG’s responsibility and cost. This includes the 11 kV or 33 kV cable or overhead line from your plant boundary to the substation bay, the switchgear in the new bay, and all associated civil works. This cost — often ₹15–40 Lakh per MW depending on distance — is a critical variable in the project financial model that is frequently underestimated at the application stage.
According to CEA’s Annual Growth Report 2024, distributed generation capacity additions under PM-KUSUM and related decentralized solar schemes in India reached 4.2 GW cumulatively by March 2024. The target under the revised PM-KUSUM for Component A is 10 GW across all states — indicating significant pipeline for EPC developers focused on this segment.
Post-Execution: Maintenance and Performance Monitoring
MNRE guidelines and the terms of the PPA make it the RPG’s responsibility to maintain the plant’s generation performance throughout the 25-year contract. The DISCOM does not operate or maintain the plant — it only purchases the power.
A maintenance program that protects CUF over 25 years requires:
Regular maintenance (ongoing):
- Solar module cleaning at minimum twice per month — critical in dusty agricultural zones. Soiling in central India can reduce PR by 10–15% without cleaning. Monthly cleaning cost of ₹15,000–25,000 for a 1 MW plant is a small fraction of the ₹2–3 Lakh annual revenue at risk.
- Quarterly inspection of inverters, DC combiners, cable connections, and mounting structure bolts
- Annual inspection of earthing continuity and lightning protection system integrity
Performance monitoring:
- Real-time SCADA monitoring with PR and CUF dashboards. Monitoring systems cost ₹2–4 Lakh per MW but prevent invisible yield drain from undetected inverter faults or string failures
- Annual infrared (thermographic) imaging to identify hotspot cells and poor connections before they cause module degradation
- Annual string-level IV curve testing to verify actual vs. expected string performance
Note. The 19% CUF requirement for CFA disbursement applies to 2 consecutive months — typically assessed in the first operational quarter. However, maintaining CUF above 19% over the full 25-year PPA lifetime is what protects your ROI. A plant that achieves 21% CUF at commissioning but drops to 17% by Year 7 due to soiling and degradation is losing ₹2–3 Lakh per year in unrealized generation revenue — more than the total annual O&M cost. Monitor CUF quarterly and investigate causes immediately when it drops below 18%.

FAQ
What is the CUF requirement for PM-KUSUM Component A CFA?
CUF must be at least 19% for 2 consecutive months to qualify for 100% of the Central Financial Assistance under PM-KUSUM Component A. This is calculated as: actual kWh generated in the 2-month period divided by (installed kW × hours in 2 months) × 100. For a 1 MW plant over 60 days (1,440 hours), the minimum is 273,600 kWh. Most well-designed plants in high-irradiance Indian states (GHI > 5.0 kWh/m²/day) achieve 21–25% annual CUF, providing a comfortable buffer above the 19% threshold.
What is the application fee for PM-KUSUM Component A?
The application fee is ₹5,000 per MW, charged at the time of EOI submission to the DISCOM. This fee is non-refundable regardless of outcome — including if the application is rejected, withdrawn, or not selected in a bidding process. In addition to the application fee, an Earnest Money Deposit (EMD) of ₹1 Lakh per MW must be submitted as a bank guarantee from a scheduled commercial bank. The EMD is convertible to a Performance Bank Guarantee (PBG) upon LoA issuance.
Can a farmer lease land for PM-KUSUM Component A without investing in the project?
Yes. A farmer who does not have capital to develop the solar project can lease their land to a developer or company, which acts as the RPG. The landowner earns a fixed lease rental (agreed between landowner and RPG — typically ₹50,000 to ₹1 Lakh per acre per year), while the developer installs and operates the plant and receives the DISCOM PPA revenue. The CFA and state subsidy go to the RPG, not the landowner. The lease agreement must be for at least 25 years and executed on stamp paper.
What happens if the RPG misses the commissioning deadline?
Missing the commissioning deadline stipulated in the LoA triggers progressive penalties: PBG encashment at defined rates per month of delay, and potential LoA cancellation if the delay exceeds a maximum period (typically 3–6 months beyond the deadline per state guidelines). The PBG (typically ₹5–10 Lakh/MW) is at risk. To protect against commissioning delays, the RPG must finalize EPC selection, equipment procurement, and grid connection coordination well before the deadline. Starting EPC tendering within 1 month of LoA issuance is the recommended practice.
How is the PPA tariff determined for PM-KUSUM Component A?
If total applications for a specific substation are within the available capacity, the LoA is issued at the pre-fixed levelized tariff determined by the SERC. This tariff varies by state — typically ₹3.0–4.5/kWh in 2025. If applications exceed capacity at that substation, competitive bidding determines the final tariff for each winner, with the pre-fixed rate as the ceiling. Winners receive LoAs at their individual bid rates. No bidder can receive a tariff above the pre-fixed rate, and the lowest bidder wins priority allocation.
What financing is available for Component A projects?
MNRE guidelines provide a model financing structure: 30% CFA (central subsidy) + 30% state subsidy + 30% bank loan + 10% RPG equity. In practice, bank loan structures for 1 MW rural solar projects include IREDA’s term loan schemes for small RE projects, NABARD’s rural infrastructure lending for farmer-owned projects, and nationalized banks’ priority sector lending for agricultural sector solar. Interest rates for IREDA-financed PM-KUSUM projects typically run 8.5–10.5% per annum. Payback period on the 40% owner contribution (subsidy + equity) is typically 3–5 years.
Does PM-KUSUM Component A apply across all Indian states?
PM-KUSUM Component A is a central scheme but requires state government implementation agencies (typically the nodal agency designated by the state energy department) to float tenders, manage applications, and issue LoAs through DISCOMs. As of 2025, states with active Component A programs include Gujarat, Rajasthan, Madhya Pradesh, Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, and Andhra Pradesh. State-specific tariffs, application timelines, and subsidy structures differ. Visit the PM-KUSUM MNRE portal for state-wise status and current tenders.
