Two energy bills.
One plan to cut both.
One provider for green electricity, green heat and the data that proves both — from press shop to paint shop to dispatch.
About ₹6.08 a unit across the year with solar and wind, against ₹7.96 from the grid.

Press to dispatch/ where we intervene
Every shop
has a lever.
Coils arrive, presses stamp, robots weld, the paint shop heats and cools, assembly builds, carriers leave. jouleWise acts at ten points across the plant — four layers, one plan.
Green sourcing
Intrastate and ISTS solar and wind contracted through open access, routed for the lowest landed cost.
ElectricityConnectivity and metering
Open access approvals, connection agreement and ABT metering at the plant incomer.
ElectricityRooftop solar
Press and body shop roofs carry behind-the-meter solar, sized from measured load.
ElectricityBattery storage
LFP storage moves midday solar into the evening shift and shaves peak demand.
ElectricityHeat pumps on pretreatment
Degreasing and conversion baths heated by heat pumps instead of PNG or diesel burners.
HeatThermal storage
Hot water store charged in solar blocks, drawn across all shifts.
HeatWaste heat recovery
Compressor-house and chiller-condenser heat lifted back to process temperature.
HeatergOS control
15-minute metering of electricity, heat, fuel and water; forecasting, trading and heat dispatch.

Low-cost
green electricity.
Presses, welding lines, compressed air and paint-shop HVAC set a two- or three-shift load. We build the green portfolio to that profile — and move heat pump load into the solar hours, where green electricity is cheapest.
Hover the profile to read any 15-minute block
Two shifts, with the paint shop as the heat load: pretreatment baths and washers held at temperature from the first shift to the last. The store is brought up before the morning shift, in the cheapest blocks, so the day starts without the boiler.
Plan
Meter-data due diligence: bills, load survey, rooftop and captive parameters. Solar, wind, hybrid, BESS and exchange electricity 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.
Heat/ what moves, what stays
The boiler,
reinvented.
Most paint-shop heat is low-temperature: cleaning baths, conversion coating, booth air and washers sit well below 120 °C. Industrial heat pumps serve those loads with electricity — so as electricity gets cheaper and greener, so does every unit of heat.
Heat sources we reuse
Compressed-air compressors, ED bath and chiller condensers, oven and booth exhaust — heat you already pay for, lifted back to process temperature.
Heating and cooling at once
The ED bath and paint-shop HVAC need cooling while pretreatment needs heat. One heat pump serves both — the cooling load becomes the heat source.
Sized from metered heat
Portable heat meters log flow and temperature on candidate processes for two to four weeks before anything is sized.
Economics/ illustrative
Low-cost electricity
drives low-cost 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 electricity; green electricity 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 electricity treated as zero-emission on a market basis with green attributes retired. Heat pump COP 4.0 reflects hot water near 60 °C for pretreatment, lifted from compressor and chiller waste heat; COP falls as delivery temperature rises. Tariffs, fuel prices and COP vary by site and are replaced with metered values in the baseline.

Operate and discloseEvery block · every year
ergOS runs electricity and heat; esgOS publishes BRSR Core-format, CBAM, CDP and customer disclosures with an audit trail.
We can fund it. You choose how. Each lever — electricity or heat — can be bought four ways, and the two levers can be bought differently.
Timelines indicative; confirmed after the baseline and dependent on state approvals and equipment lead times.

In short/ Automotive
The Automotive playbook is jouleWise's typical engineering approach for automotive plants: two energy bills. one plan to cut both.
One provider for green electricity, green heat and the data that proves both — from press shop to paint shop to dispatch. For a vehicle or component maker, decarbonisation has moved from a CSR line to a sourcing condition. Six pressures point at the same metered data. Most paint-shop heat is low-temperature: cleaning baths, conversion coating, booth air and washers sit well below 120 °C. Industrial heat pumps serve those loads with electricity — so as electricity gets cheaper and greener, so does every unit of heat.
What to take away
- Heat duties and temperatures: Pretreatment degreasing 45–60 °C (heat pump); Conversion coating 30–55 °C (heat pump); ED bath and rinses 28–35 °C (heat pump); Paint booth air 20–30 °C (heat pump); Parts washers 50–80 °C (heat pump); Canteen and hot water 55–65 °C (heat pump); Sealer and PVC ovens 130–160 °C (stays on fuel); ED and topcoat ovens 140–190 °C (stays on fuel).
- PNG-fired boiler: ₹6.22 per kWh of useful heat, 0.221 kg CO₂/kWh-th
- Diesel (HSD) boiler: ₹10.59 per kWh of useful heat, 0.315 kg CO₂/kWh-th
- Heat pump on DISCOM electricity: ₹2.12 per kWh of useful heat, 0.179 kg CO₂/kWh-th
- Heat pump on green open access: ₹1.38 per kWh of useful heat, 0.000 kg CO₂/kWh-th
- Heat pump in solar blocks + store: ₹1.00 per kWh of useful heat, 0.000 kg CO₂/kWh-th
- Plant areas with a lever: Pretreatment baths, Paint-shop washers, Compressed-air heat recovery, Chiller heat recovery, Shift-profile electricity.
