Project Report for Potato Cold Storage
Potato cold storage is one of India’s most established agri-infrastructure businesses—not a novel concept, but one with strong structural demand, particularly outside of the saturated UP and West Bengal markets. The combination of the NHB subsidy, the AIF interest subvention, and the loan-against-storage revenue model makes the economics truly enticing in the proper location. Sharda Associates, which has delivered over 45,500 project reports, creates CA-certified potato cold storage DPR. Starting at ₹2,999.

Why Potato Cold Storage, Even When So Much Already Exists
India has a lot of cold storage capacity, most of which is dedicated to potatoes. Uttar Pradesh and West Bengal collectively account for the majority of India’s potato cold storage capacity. So, why is it still worthwhile to examine modern potato cold storage?
Because capacity concentration generates its own gaps. A farmer in a district 150 kilometres from the nearest storage facility has the same distress-sale issue that cold storage was designed to address: the pressure to sell at harvest-time low prices because there is nowhere to store the produce. In areas where potato farming is growing but cold storage capacity has not kept up, a new facility is immediately in high demand.
Even when capacity exists in aggregate, older facilities (pre-2000 construction with deteriorated insulation and outdated refrigeration) are losing customers to newer, better-insulated facilities that offer better preservation quality and, more importantly, the ability to provide quality certificates that modern processors and exporters require.
The question isn’t “is there cold storage in India”; it’s “is there cold storage of the right quality and in the right location for your target district.”
The Business Model — Storage Fee and Something More
Most people think of potato cold storage as a facility with a storage cost. That is the obvious part. The loan-against-storage layer enhances the existing business model.
This is how it works. A farmer transports potatoes to cold storage during harvest season, when market prices are low. The cold storage facility issues a warehouse receipt for the stored quantity. The farmer takes this receipt to a bank and obtains a loan (usually 60-70% of the market value of the stored potato) without selling the crop. The farmer waits for prices to recover (typically 3-6 months), then sells at a higher price, repays the bank, and gets any remaining funds after loan payback.
The cold storage operator benefits from this arrangement in two ways: the farmer is encouraged to bring potatoes to the storage (because the storage facilitates the loan), and in some established markets, the storage operator also provides the loan directly from their own funds, charging interest — combining the storage and informal lending businesses into a single operation.
A new storage facility cannot implement this loan-against-storage model right once because it requires an established farmer relationship, a functioning warehouse receipt system, and (for formal bank-linked loans against storage) empanelment with financing banks. However, it is what makes the mature potato cold storage business far more profitable than storage prices alone would indicate.
The Specifics — Temperature, Humidity, and Why They Matter
Potatoes are stored at 2-4°C and 90-95% relative humidity. Too cold (below 2°C), and the potato’s starch turns to sugar, reducing cooking quality – a quality complaint that purchasers will file with the storage operator. When temperatures climb above 6°C for an extended length of time, sprouting speeds up, shrinking increases, and disease risk rises.
Humidity control is similarly crucial. Too dry (less than 85% RH), and the potato dehydrates, losing weight (which the farmer recognizes right away when they weigh it) and develops skin quality difficulties. Fungal illness is caused by a high level of humidity, inadequate air circulation, and surface condensation.
Getting these conditions right requires:
- PUF (Polyurethane Foam) insulated panels are the conventional construction for modern potato cold storage, replacing earlier brick-and-mortar structures with straw insulation.
- Refrigeration system sized for the load—undersized refrigeration cannot draw the storage down to 2-4°C and retain it there even when the ambient temperature is 45°C outdoors.
- Forced air circulation ensures consistent temperature throughout the stored bulk, not just at the evaporator.
- Humidity control – humidifiers or natural humidity management based on the storage architecture.
The refrigeration system, which includes compressors, condensers, and evaporators, is the most capital-intensive and technically crucial component. Storage quality issues are primarily caused by an inadequate or poorly specified refrigeration system.
Minimum Viable Scale — Why 1,000 MT Is Usually the Floor
This is a practical question that many hopefuls do not ask early enough: what is the smallest size of potato cold storage that is financially viable?
The economics of cold storage include considerable fixed costs – refrigeration machinery, electrical infrastructure, DG backup, and basic civil construction all have minimum costs independent of storage size. A 200 MT storage has about the same fixed expenses as a 1,000 MT storage, but yields one-fifth the storage charge revenue.
In practice:
- Below 500 MT: It is extremely tough to make the economics work. The fixed cost per tonne of capacity is excessively high as compared to storage charge revenue.
- 500-1,000 MT: Possible, but limited, particularly with debt funding. Requires a prime location and strong occupancy.
- Most banks and subsidy schemes consider 1,000-2,000 MT to be the minimum viable commercial scale.
- 2,000-5,000 MT: The normal commercial range with improved fixed cost distribution.
The NHB and AIF scheme evaluations favor 1,000 MT+ projects since the economics are proven more realistic at this magnitude.
Subsidy Schemes For Potato Cold Storage
NHB (National Horticulture Board) — 35% Credit-Linked Backend Subsidy: Potatoes are clearly classified as a horticulture commodity under NHB’s program, which may surprise some applicants who identify NHB with fruits. 35% of the qualified project cost (55% in northeastern/hilly states) is released following construction, inspection, and verification. Credited to the bank loan account, decreasing the remaining principal. Not paid beforehand.
AIF (Agriculture Infrastructure Fund) offers a 3% interest subvention for loans up to ₹2 crore over 7 years, with CGTMSE collateral-free coverage. Can be paired with NHB on the same project; various mechanisms function on different aspects of the financial structure.
NABARD Refinance: NABARD refinances partner banks’ cold storage loans, allowing for more competitive interest rates. For a ₹2 crore project, NHB offers a post-construction subsidy of ₹70 lakh, whereas AIF offers interest savings of around ₹42,000 per year for 7 years. The total effective cost decrease is considerable.
Project Cost For Potato Cold Storage
Capacity | Estimated Project Cost (₹) |
500 MT (minimal commercial scale) | ₹75 lakh – ₹1.25 crore |
1,000 MT (entry commercial) | ₹1.25 – ₹2 crore |
2,000 MT (standard commercial) | ₹2 – ₹3.50 crore |
3,000-5,000 MT (larger commercial) | ₹3.50 – ₹6.50 crore |
Major cost components: PUF insulated panel construction (chamber), refrigeration system (compressors, condensers, evaporators — sized in Tonnes of Refrigeration), DG set backup (mandatory — potato can’t tolerate extended power outage), and electrical infrastructure.
Seasonal Revenue — The Cash Flow Reality
Potato cold storage revenue is concentrated between April and October, when farmers and traders withdraw stored potatoes to sell as prices recover throughout the year following harvest. The storage fills in November-January (after harvest) then empties during the next 8-9 months.
This means:
- Months with the largest revenue: April-September (withdrawal time, storage fees collecting).
- Months with the lowest revenue: October-December (storage is filled — fees start mounting, but payment comes later).
Loan repayment must correspond to this cash flow. A flat monthly EMI that overlooks seasonality will leave the operator unable to service the loan between October and December, when cash flow is lowest. Banks that specialize in agri-infrastructure funding often allow seasonal repayment schedules; the project report must specifically propose and justify this.

Frequently Asked Questions
In practice, 1,000 MT is the minimum commercial scale that banks and subsidy schemes consider viable — the fixed costs of refrigeration, electrical infrastructure, and civil construction create a cost-per-tonne floor that makes smaller facilities (less than 500 MT) difficult to finance with debt.
The National Horticulture Board provides a 35% credit-linked backend subsidy (potato is an NHB-eligible horticulture commodity). AIF (Agriculture Infrastructure Fund) offers a 3% interest subsidy for 7 years on loans up to ₹2 crore with CGTMSE coverage. NABARD refinances through banks. All three can be merged into a single project.
Yes, potato is categorized as a horticulture commodity under the NHB plan, despite its prevalent misconception as a field crop rather than a horticultural crop. Many applicants are astonished to discover this. The NHB's 35% subsidy (55% in northeastern/hilly states) applies to potato cold storage buildings.
2-4°C and 90-95% relative humidity. Potato starch is converted to sugar at temperatures below 2 degrees Celsius (quality concern). Extended exposure to temperatures above 6°C increases sprouting and weight loss. Humidity levels below 85% promote dehydration and weight loss, which farmers observe upon withdrawal. Both require good refrigeration and forced air movement.
Farmers that stockpile potatoes can take out a bank loan against the warehouse receipt (usually 60-70% of market value) instead of selling their crop, allowing prices to recover before selling. The cold storage operator gains since it encourages farmers to transport potatoes to storage, and in some markets, the operator provides the loan directly, collecting interest in addition to storage fees.
Potatoes cannot withstand extended power outages; a temperature surge during a prolonged outage causes sprouting and quality damage, making the storage operator liable to the stored farmers. An appropriately sized DG set (one that can handle the entire refrigeration demand, not just a portion of it) is a non-negotiable capital item. It should be factored into the project budget rather than considered as an optional extra.
Highly seasonal. Storage fills from November to January (after harvest, revenue begins to accrue, but cash collections are limited). Withdrawal and peak revenue occur from April to September as farmers sell stored cattle. The lowest cash flow period is October-December; loan repayment schedules must reflect this rather than assuming a flat monthly repayment capacity.
Modern cold storage chambers are built with PUF (Polyurethane Foam) insulated panels, which are prefabricated and replace traditional brick-and-mortar construction with straw or other insulation. PUF panels offer better, more consistent insulation (reduced heat gain into the chamber), faster installation, and a longer effective life. The technical standard evaluated by NHB includes the thickness of the PUF panel (usually 100-150mm for potato storage) as well as its insulation value (R-value).
Yes, a potato cold storage facility can be developed over time to include other chambers at different temperature zones (fruit, vegetable, pharmaceutical), transforming it from a single-commodity facility to a partial multipurpose facility. This staged method — begin with potato (proved demand and simpler operation), then add multipurpose capacity once the first phase is built and operational — is a common and reasonable development path for operators in suitable regions.
