Green power.
Green heat.
One stack.
For textile mills and processing houses.
One provider for green power, green heat and the data that proves both — from spinning floor to dye house to export container.
Most of your heat
is below 100 °C.
A textile processing unit runs on hot water. Desizing, scouring, bleaching, dyeing and washing heat large volumes of water to 40–98 °C, mostly with coal, biomass or PNG boilers and thermic fluid heaters — then send that water, still warm, to the effluent plant. Many global brands have committed to phasing coal out of their tier 1 and tier 2 supply chains, and ask mills for renewable power and Scope 1 and 2 data.
Power, heat and ESG reporting are bought from different vendors on different clocks. Solar is sized without the heat load; boilers are replaced without a plan for cheaper power; ESG data is typed in once a year. Each fix leaves money and carbon on the table.
jouleWise runs the whole decarbonisation stack: green power — intrastate and ISTS solar and wind, rooftop solar, BESS and green-market purchase, each source orchestrated to fulfil industrial demand at least cost; ABT metering and data loggers on every source and load; green heat from industrial heat pumps up to 120 °C; ergOS to meter and orchestrate both every 15 minutes; esgOS to turn the same data into audit-ready disclosure.
Cheaper green power lowers the cost of every unit of heat a heat pump makes. Thermal storage lets that heat be made in the cheapest solar blocks. ergOS proves it; esgOS reports it. Savings from one layer fund the next.
Up to 25% lower power cost on DISCOM tariff and up to 65% renewable share (reported, year 1 of ergOS). Heat pumps then recover heat from warm effluent and deliver dye-house hot water — on green power, cheaper than coal-fired heat and close to zero-carbon.
Four models, mix and match: Advisory, SaaS (ergOS + esgOS), Heat Advisory, and Heat as a Service, where you pay per unit of heat and invest nothing upfront.
A four-week decarbonisation baseline on one mill: power bills, load survey, coal and fuel records, and portable heat metering on dyeing, washing and effluent streams — ending in one business case for power, heat and ESG.
Reported client impact, year 1 of ergOS; C&I client outcomes. Results vary with state, tariff structure and load profile. Textile-specific value is quantified in the baseline.
Your brands are
phasing out coal.
For a spinner, weaver or processor, decarbonisation now decides which brand programmes you stay in. Six pressures point at the same metered data.
Brand supplier targets
Global apparel and home-textile brands have set supply-chain emission targets and ask tier 1 and tier 2 mills for renewable power, Scope 1 and 2 data and a coal exit plan.
Coal phase-out
Coal-fired boilers and thermic fluid heaters are the single largest source of a mill's emissions — and the first thing brand audits ask about.
EU product rules
The EU's ecodesign rules are moving textiles towards digital product passports that carry environmental data back to the mill.
Heat and power cost
Hot water and drying are the largest energy costs in wet processing; spinning and weaving run three shifts on power. Both go straight to margin.
Water and effluent
ZLD and discharge norms tie water, heat and chemicals together. Cooler, cleaner effluent helps the ETP as well as the heat balance.
Carbon markets
Textiles is among the sectors named for emission-intensity targets under India's Carbon Credit Trading Scheme. Mills that measure now are ready.
One stack.
Every layer feeds the next.
Most plants buy decarbonisation in pieces. We built it as a loop: low-cost green power feeds heat pumps, storage moves heat into the cheapest blocks, ergOS runs it, esgOS proves it.
Green power
Intrastate and ISTS solar and wind, rooftop solar, BESS and green-market purchase — each source orchestrated to fulfil industrial demand at least cost.
Heat pumps
Every kWh in becomes three to four kWh of useful heat. The boiler stops burning fuel for loads up to 120 °C.
Thermal storage
Heat is made when power is cheapest and greenest, and used when the process needs it.
ergOS
Meters power, steam, fuel and water every 15 minutes; forecasts, schedules and trades; runs heat pumps against price.
esgOS
Converts the same metered data to Scope 1, 2 and 3, BRSR Core-format, CBAM, CDP and customer disclosures.
Every bath
has a lever.
Bales arrive, yarn is spun and woven, fabric is scoured, dyed, washed and dried, finished goods leave in containers. jouleWise acts at ten points — most of them on hot water.
Green sourcing
Intrastate and ISTS solar and wind contracted through open access for a three-shift load.
PowerConnectivity and metering
Open access approvals, connection agreement and ABT metering at the mill incomer.
PowerRooftop solar
Spinning and warehouse roofs carry behind-the-meter solar, sized from measured load.
PowerBattery storage
LFP storage for peak shaving and to keep spinning frames and humidification steady.
PowerHeat pumps on dye-house water
Hot water for scouring, bleaching, dyeing and washing made by heat pumps instead of coal steam.
HeatEffluent heat recovery
Warm dye and wash effluent becomes the heat pump source — and reaches the ETP cooler.
HeatHot-water store
Store charged in solar blocks and drawn batch by batch across the day.
HeatStenter exhaust recovery
Stenters stay on thermic fluid; their exhaust heat is recovered into the hot-water circuit.
HeatergOS control
15-minute metering of power, steam, hot water, fuel and water — per machine where it matters.
Data · ergOSBrands and exports
Brand questionnaires, coal-exit evidence and per-kg fabric carbon from esgOS.
ESG · esgOSIllustrative plant. Actual intervention map built site by site in the baseline.
Low-cost
green power.
Spinning and weaving run three shifts with humidification and compressed air; processing adds pumps, jets and dryers. The load is high day and night — heat pump load moves into solar hours with a hot-water store.
Plan
Meter-data due diligence: bills, load survey, rooftop and captive parameters. Solar, wind, hybrid, BESS and exchange power optimised together, capex or opex, with each state's ToD, banking and open access charges in the landed-cost model.
Implement
RfP over a 25-year horizon, developer evaluation, reverse auction, PPA and shareholder agreements (26% SPV equity for captive status), open access approvals and connection agreement.
Meter and log
ABT meters at injection and drawal points — main and check meters on CTs and PTs of the required accuracy class — plus data loggers on every incomer, heat pump, steam, fuel and water line. Installed, tested, sealed and linked to the SLDC and to ergOS.
Orchestrate
ergOS forecasts 96 blocks, schedules with the SLDC, trades DAM, GDAM, RTM and GTAM, manages banking and battery health — and now dispatches heat pumps and thermal storage against price.
What is a
heat pump?
A heat pump is a refrigerator run the other way round. It does not make heat by burning anything — it moves heat that already exists, from a cooler place to a hotter one, and uses electricity only to do the lifting.
Swipe to see the whole cycleWhat goes in, what comes out
COP (coefficient of performance) = useful heat ÷ electricity. A boiler can never exceed 1; a heat pump typically delivers 2 to 5.
Temperature lift sets the COP · indicative
Lift = delivery temperature minus source temperature. Recovering warm waste heat first and delivering no hotter than the process needs keeps the COP high.
For loads up to 120 °C, yes — as the primary heat source. The boiler usually stays on standby and for any loads above that range.
Each kWh of power returns three to four kWh of heat, so heat costs roughly a third of the power price. On green open access, the carbon falls close to zero as well.
Spare electrical capacity, space near the heat users and a steady heat demand. A hot-water store smooths peaks and lets the unit run in the cheapest blocks.
It is the same refrigeration cycle as the chillers already on your site, run for heat. Industrial units are in service worldwide in food, chemicals, pharma and textiles.
The boiler,
reinvented.
Wet processing is a hot-water business: most baths run between 40 and 98 °C, well inside heat pump range. The high-temperature exceptions — HT polyester dyeing and stenters — stay on steam or thermic fluid, with their exhaust heat recovered.
Heat sources we reuse
Warm effluent from dye and wash baths, stenter exhaust, condensate and air-compressor heat — much of a mill's heat currently goes down the drain.
Effluent as the source
Effluent at 40–60 °C is an excellent heat pump source: the small temperature lift means a high COP, and cooler effluent eases the load on the ETP.
Sized from metered heat
Portable heat meters log flow and temperature on candidate processes for two to four weeks before anything is sized.
Cheaper power
makes cheaper heat.
What one kWh of useful process heat costs, and what it emits, depending on where the heat comes from. The heat pump cuts cost on any power; green power is what cuts the carbon.
Illustrative only, not an offer. Assumptions: PNG 10.4 kWh/SCM, 1.95 kg CO₂/SCM; HSD 10.0 kWh/L, 2.68 kg CO₂/L; grid 0.716 kg CO₂/kWh (CEA baseline order of magnitude); green power treated as zero-emission on a market basis with green attributes retired. Heat pump COP 3.8 reflects hot water near 85 °C drawn from warm dye-house effluent; COP falls as delivery temperature rises. Tariffs, fuel prices and COP vary by site and are replaced with metered values in the baseline. Coal: ₹8,000/t, 4,000 kcal/kg (4.65 kWh/kg), 1.7 kg CO₂/kg, 75% boiler efficiency.
