What drives biomass pellet plant economics in India
A biomass pellet plant is a spread business: you buy loose agricultural residue or wood waste, densify it into fuel pellets, and sell to thermal power plants, industrial boilers and brick kilns. Whether the plant makes money comes down to four levers — the delivered price of your feedstock, the moisture you must dry off, your capacity utilisation, and the sale price you secure. Feedstock alone is 45–65% of cost, so a firm supply contract at a good rate is the single biggest predictor of a healthy plant.
Feedstock is 45–65% of your cost
Nothing else moves the outcome as much as the delivered price of your feedstock and how reliably you can secure it. Rice husk, paddy straw, mustard and cotton stalk, groundnut shell, sawdust and bagasse each sit at a different point on the price-and-quality curve. Most failures trace back to feedstock cost creeping up or supply drying out in the off-season.
Power, and the moisture that drives it
Size reduction, drying and pelletising are energy-intensive. A well-designed agri-residue line uses roughly 90–150 kWh per tonne of pellets; wet feedstock that needs heavy drying can push total energy several times higher. Because power is 15–25% of operating cost at Indian industrial tariffs, the moisture content of your feedstock quietly decides a large part of your bill.
Utilisation, subsidy and the loan
Fixed costs — manpower, maintenance, the term-loan EMI — do not shrink when the line sits idle, so utilisation is what turns a technically sound plant into a profitable one. The MNRE Biomass Programme softens the capital hurdle with ₹21 lakh per MTPH of assistance for non-torrefied pellet plants (capped at ₹1.05 crore), and a typical 70% term loan spreads the rest.
Pellet prices by feedstock — 2026 ranges (₹/t)
| Feedstock | Pellet sale ₹/t | GCV kcal/kg | Feedstock ₹/t | Note |
|---|
| Mixed agri-residue | 6,500 – 9,000 | 3,400 | 3,000 | balanced default |

| Rice husk | 6,000 – 7,500 | 3,400 | 4,700 | high ash, thin margin |
| Groundnut shell | 7,500 – 11,500 | 3,600 | 3,800 | good calorific value |
| Sawdust / wood | 8,000 – 14,000 | 4,200 | 6,000 | premium, cleanest burn |
| Bagasse | 6,000 – 7,500 | 3,600 | 2,200 | cheap, seasonal supply |

India produces well under 5 million tonnes of pellets a year against a co-firing mandate that alone needs 15–20 million tonnes, so a well-run plant competes on quality and consistency rather than for customers.

Frequently asked questions
How much does it cost to set up a biomass pellet plant in India?
A turnkey agri-residue plant runs roughly ₹1.4 crore for 1 TPH, about ₹2.5 crore for 2 TPH and ₹5 crore or more for 5 TPH, covering machinery, drying, civil work, electricals, storage and margin money. Wood-grade lines with heavier drying cost more. The MNRE Biomass Programme gives a capital subsidy of ₹21 lakh per MTPH for non-torrefied pellet plants (revised July 2024), capped at ₹1.05 crore, which the calculator applies to your net project cost.
Is a biomass pellet plant profitable, and what margin can I expect?
For a well-run agri-residue plant, net margins after EMI typically land in the 15–25% range, with EBITDA margins a few points higher. Feedstock is the swing factor — it is 45–65% of operating cost — so the gap between your delivered feedstock price and your pellet sale price decides everything. Cheap, secured feedstock and a firm offtake contract are what separate a healthy plant from a marginal one.
What is the payback period on a biomass pellet plant?
With the MNRE subsidy and a typical 70% term loan, a simple payback on EBITDA usually falls between about 1.5 and 3 years for a well-utilised plant, extending if utilisation is low or feedstock is expensive. The calculator shows your payback and return on equity live as you change capacity, feedstock and utilisation.
What government subsidy is available for biomass pellet plants?
Under the MNRE Biomass Programme (revised 16 July 2024), non-torrefied pellet plants get Central Financial Assistance of ₹21 lakh per MTPH — or 30% of a 1-MTPH line's machinery cost, whichever is lower — capped at ₹1.05 crore per plant; torrefied plants get ₹42 lakh per MTPH capped at ₹2.1 crore. Applications go through the BioURJA portal before commissioning, within a 12-month window, and full CFA needs about 80% of rated capacity. State nodal agencies and priority-sector lending can add further support.
How much electricity does biomass pellet production use?
A well-designed agri-residue line draws roughly 90–150 kWh per tonne of pellets for size reduction, pelletising, cooling and conveying. Wet feedstock that needs heavy drying pushes total energy far higher — up to 400–600 kWh per tonne on the full wet-wood chain — which is why moisture content matters so much. At an industrial tariff around ₹8 per kWh, power is usually 15–25% of operating cost.
Which feedstock is the most profitable for pellets?
Profit comes from the spread, not the material. Sawdust and wood waste fetch the highest pellet prices (₹10,000–16,000 per tonne) but cost the most to buy. Groundnut shell and mustard offer a good balance. Rice husk is abundant and cheap to source but abrasive — it wears dies faster and its pellets sell at the lower end, so margins are thin. Mixed agri-residue built around cheap paddy straw is the common, defensible entry point.
What is the selling price of biomass pellets in India in 2026?
Ex-factory agri-residue pellets typically sell for ₹6,000–11,000 per tonne depending on grade, ash and calorific value, while wood pellets command ₹8,000–15,000 per tonne. Prices vary by state, feedstock and season — agri-residue softens around harvest. PelletRates tracks live rates across 35+ states.
How much feedstock is needed to make one tonne of pellets?
For fairly dry agri-residue you need about 1.05–1.15 tonnes of loose feedstock per tonne of finished pellet, once moisture reduction and fines loss are accounted for. Wet feedstock such as bagasse can push that to 1.4 tonnes or more. The calculator derives this ratio from the moisture-in, moisture-out and process-loss you set.
How many tonnes per year does a 1 TPH pellet plant produce?
At around 85% utilisation on continuous operation, a 1 TPH plant makes roughly 7,000–8,000 tonnes a year; a 2 TPH plant about 13,000–14,000 tonnes. Actual output depends on operating hours, planned maintenance days and how consistently you can feed the line — which is a feedstock and manpower question as much as a machine one.
How long do pellet mill dies and rollers last?
A normal ring die handles about 3,000 tonnes before replacement; a better die 5,000–7,000 tonnes. Rollers wear faster. Abrasive, high-silica feedstock such as rice husk shortens die life and raises consumable cost per tonne, which is captured in the calculator's die-and-roller line.
