Our anchor business · Thermal SaaS

Industrial heat, delivered as a service.

We design, build, own and operate the entire thermal plant on your site — boiler, fuel chain, water treatment, emissions stack, controls and crew. You sign a 10–20 year take-or-pay tariff and pay per ton of steam consumed. Zero CAPEX leaves your balance sheet untouched; a contractual 98–99.5% uptime SLA puts the reliability risk on us. Biomass leads the fleet, our new renewable-powered electric boilers take the zero-emission duties, and hydrogen-ready gas covers everything in between.

Four energy routes · One contract

Fuel-agnostic by design.
We pick what your site economics demand.

Every tariff starts with a fuel-cost model of your site. Biomass wins most of the time — but the right answer is increasingly a blend, and our new electric route now serves loads combustion never could.

Biomass — the flagship

Agro-waste briquettes, pellets, husk and bagasse fired in chain-grate and fluidised-bed boilers. Renewable, carbon-neutral over its lifecycle, and routinely 20–40% cheaper per MMBtu than oil or LPG. We run the entire fuel supply chain.

The biomass fleet

Electric + renewables NEW

Electrode and resistance boilers fed by dedicated solar and wind PPAs. ~99% conversion efficiency, zero on-site emissions, no stack, no fuel trucks. The cleanest steam we have ever delivered.

Explore electric boilers

Gas — hydrogen-ready

LPG and natural gas firing where the biomass supply chain doesn't reach. Every new gas plant ships with burners rated for up to 30% hydrogen blending and a documented conversion path to 100% green H₂ mid-contract.

The gas-fired range

Hybrid — the optimiser

Biomass as baseload, electric or gas as the peaking and standby layer. ClearOS™ dispatches whichever source is cheapest and cleanest minute-by-minute — you see one steam header and one per-ton invoice.

How ClearOS dispatches
The biomass fuel book

Renewable industrial heat.
Cheaper than coal once externalities count.

Biomass is our preferred fuel wherever the supply chain works. We contract aggregators, test every truckload for moisture and ash, and meter the fuel daily — you see one transparent per-MMBtu tariff with 10–20 years of supply visibility.

  • Agro-waste briquettes · 3,800–4,200 kcal/kg. Compressed groundnut shell, mustard husk, cotton stalk and sawdust. Consistent moisture and calorific value — the workhorse fuel.
  • Wood pellets & chips · 4,200–4,800 kcal/kg. Densified pellets and chipped offcuts from FSC-aligned sources. Highest energy density, cleanest automated handling.
  • Paddy husk & bagasse · 3,200–3,800 kcal/kg. Rice-milling and sugar-industry residues, locally abundant across Indian agri-belts. Runs in our fluidised-bed and reciprocating-grate boilers.
  • Hybrid biomass + gas or electric. Biomass carries the baseload; gas or a renewable-powered electric unit catches the peaks. Tariff-optimised by ClearOS, reliability-backed by contract.

Fuel economics

Landed cost per MMBtu — every route, honestly priced.

Indicative ranges across our Indian customer base at 2026 prices. Actual tariffs depend on location, logistics, plant efficiency and contract term — we run a fuel-cost model on every prospective site before we quote.

Energy routeIndicative landed costCO₂ intensity (lifecycle)Notes
Biomass briquettes₹ 280 – 380 / MMBtuNear-zero (renewable fuel cycle)Best landed cost in most geographies. Carbon-credit and REC upside.
Electric + renewables NEW₹ 550 – 850 / MMBtuZero on-site; near-zero with PPA + REC supplySolar/wind PPAs + thermal storage + ClearOS dispatch. See electric boilers →
Natural gas₹ ~880 / MMBtu~ 50 kg / MMBtuCleanest fossil. Best where pipeline access exists; H₂-blend ready.
LPG₹ 980 – 1,280 / MMBtu~ 60 kg / MMBtuHighest reliability and lowest emissions among the fossils.
HSD (diesel)₹ ~1,450 / MMBtu~ 75 kg / MMBtuThe fuel we most often displace. Costliest heat in the table.
Coal (industrial grade)₹ ~520 / MMBtu~ 95 kg / MMBtu — highest CO₂Cheap fuel, expensive externalities. Increasingly regulated out.

The pattern across 60+ site models

Biomass wins continuous baseload almost everywhere a supply chain exists. Renewable-powered electric wins clean-steam, urban and sharp-batch duties — and the biomass-plus-electric hybrid beats either alone on most large sites. Coal only looks cheap until CO₂, compliance and license-to-operate risk are priced in.

Everything inside the tariff

One per-ton price.
The entire plant operation behind it.

No hidden O&M contracts, no surprise consumables, no compliance scramble. If it keeps steam in your header, it's our job and it's in the tariff.

Full O&M, our crew

Certified boiler operators on every shift, preventive and predictive maintenance, spares inventory, annual shutdowns and statutory inspections — staffed, scheduled and paid for by us.

Water treatment

Boiler feedwater chemistry, softening and RO plants, blowdown control and condensate-return management — protecting both the asset and your steam quality.

Emissions monitoring

Continuous emissions monitoring (CO, CO₂, NOx, SO₂, particulates), ESP/baghouse operation, and full statutory reporting to BEE, CPCB and state PCBs under your consent-to-operate.

24/7 NOC oversight

Every plant streams telemetry to our network operations centre. Anomalies are caught by predictive models hours before they become trips — it's how 98–99.5% uptime is contractually possible.

Metered billing

Calibrated steam-flow and energy meters at the battery limit. You're invoiced on measured consumption — per ton of steam or per MMBtu of hot water, HTF or cooling — with full data access.

Carbon credit & REC documentation

We register, document and monetise the carbon credits, RECs and energy-savings certificates your contract generates — biomass and electric-renewable sites are highest-yield — and share the proceeds back transparently.

What we deliver

Five thermal products. Any fuel route behind them.

Whether the input is biomass, renewable electricity, gas or a hybrid, the output you buy is the same: clean, metered, reliable energy in the form your process needs.

Process steam

Saturated or superheated, 2–200+ TPH, tiered low (≤7 bar), medium (7–17 bar) and high pressure (>17 bar / superheated). The anchor product — billed per ton delivered.

Biomass Electric Gas

Hot water

Pressurised hot water at 60–180°C for process heating, HVAC and CIP loops — common in food, dairy and hospitality. Volumetric tariff per MMBtu delivered.

Biomass Electric

Chilled water

Steam-driven absorption chillers turn one fuel input into both heat and 5–12°C cooling — for HVAC, fermentation, electronics and pharma cleanrooms. Bundles with steam contracts.

Absorption · steam-driven

HTF / thermal oil

Closed thermal-oil loops at 150–350°C for high-temperature, low-pressure duties in chemicals, rubber, resins and food frying. Fully metered with condensate-free operation.

Biomass Gas

Hot air

Direct and indirect-fired hot-air generators up to 600°C for spray driers, fluid-bed driers, plywood, tea and coffee. Switching drying loads from diesel to biomass cuts fuel cost 40–55%.

Biomass specialty

Zero-emission clean steam

For cGMP sterilisation, urban sites and hard ESG targets: combustion-free steam from our new electrode and resistance boilers, powered by solar and wind PPAs.

Contract mechanics

How a take-or-pay thermal tariff actually works.

The structure is deliberately boring: it's what lets us put crores of plant on your site at zero cost to you, and what locks your unit economics for a decade or two.

CLAUSE 01

Take-or-pay floor · 70–85%

You commit to a minimum offtake of 70–85% of contracted capacity. Below the floor, the floor still bills; above it, every extra ton is at the same base tariff. The floor is what underwrites the asset.

CLAUSE 02

Capacity charge

A fixed monthly charge for the TPH or MMBtu/hr we hold ready for you — a reservation, not a penalty. It recovers capex and keeps standby capacity spinning for your peaks.

CLAUSE 03

Quarterly fuel pass-through

The base tariff is set against a fuel baseline — biomass index, gas contract or renewable PPA. Deltas pass through quarterly on a transparent formula, so neither side carries spot volatility.

CLAUSE 04

SLA, escalation & exit

Uptime below the 98–99.5% SLA triggers rebates against the capacity charge. Tariffs escalate annually with caps and collars. At term end: renew, relocate, buy at residual value, or restructure.

Fuel-switch optionality is built in

Because capex recovery and fuel pass-through are separated, we can change the fuel input mid-contract without renegotiating: gas plants convert to green hydrogen when economics arrive, and biomass sites can add a renewable-powered electric boiler for peaks — same plant, same contract, lower carbon.

From audit to steam-on

90–180 days from signature
to steam in your header.

A thermal audit models your load profile and fuel options; a binding tariff follows within ten working days. We then build on a fixed calendar — civil, erection, IBR certification, commissioning — while your existing boiler keeps running until cut-over day.

  • Week 0–2: site audit, load-profile logging, fuel-cost model across biomass, electric and gas routes.
  • Week 2–4: binding tariff, contract execution, statutory applications (IBR, PCB consent, electrical sanction where electric).
  • Day 90–180: plant commissioned, SLA clock starts, metered billing begins. Your old boiler becomes standby or scrap value.
Common questions

Thermal-as-a-service, answered.

We finance, build and own the entire plant — boiler, fuel handling, water treatment, stack, controls. You provide land within your site and utility tie-ins; everything else is our asset and our depreciation. Your auditors see a long-term service contract for metered heat, not a leased boiler. Accounting treatment under Ind AS 116 depends on contract specifics, and we structure with your finance team during diligence.
The floor (70–85% of contracted capacity) still bills — that's the deal that funds the asset. But we size the floor conservatively against your audited historical demand, build in step-down provisions for documented capacity reductions, and contracts include force-majeure and plant-shutdown carve-outs. In practice, most customers grow into capacity rather than out of it.
Neither side speculates. The base tariff references a fuel baseline; quarterly pass-through adjusts for actual movement, up or down, on a published formula. Our scale buffers the worst of it — we contract biomass aggregators on multi-year terms with quality and price bands, and on hybrid sites ClearOS can shift load to the electric or gas route when biomass tightens seasonally.
Yes — and it's becoming our most common expansion. A renewable-powered electrode or resistance boiler ties into your existing steam header under the same contract; ClearOS dispatches biomass for baseload and electric for peaks, maintenance windows and cheap solar hours. You keep one per-ton invoice. See the electric boilers page for the hardware and the renewable supply structure.
Four options, your choice: renew on refreshed terms (most common), have us relocate the asset and make good the site, take ownership at a pre-agreed residual value, or restructure into a new SLA. There is no balloon payment and no obligation to buy — the asset risk stayed with us for the whole term.
