Executive summary / Automotive

Two energy bills.
One plan to cut both.

The situation

An automotive plant pays two energy bills. Electricity runs presses, welding robots, compressed air and paint-shop HVAC; fuel — PNG, LPG or diesel — heats pretreatment baths, washers and ovens. OEMs increasingly ask suppliers for Scope 1 and 2 numbers and a reduction plan, and EU importers of steel and aluminium goods need embedded-emissions data under CBAM.

The gap

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.

What we do

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.

Why it compounds

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.

The value

Up to 25% lower power cost on DISCOM tariff and up to 65% renewable share (reported, year 1 of ergOS). Heat pumps then displace fuel on pretreatment, washers and hot water — on green power, that heat is close to zero-carbon and a fraction of the cost of fuel-fired heat.

How to engage

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.

First step

A four-week decarbonisation baseline on one plant: power bills, load survey, fuel records and portable heat metering in the paint shop — ending in one business case for power, heat and ESG.

Why now / Automotive

The customer is
counting your carbon.

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.

OEM supplier targets

Vehicle makers are setting decarbonisation expectations for their supply base. Suppliers with metered Scope 1 and 2 data and a credible plan hold their place on the approved list.

Exports and CBAM

EU importers of iron, steel and aluminium goods report embedded emissions under CBAM. Component exporters in scope need plant-level, verifiable data.

Energy cost

The paint shop is among the largest energy users in a vehicle plant — heat, booth HVAC and ovens. Every rupee off power and fuel goes straight to margin.

Disclosure

BRSR Core-format reporting and value-chain disclosure put your energy and emissions in your customers' reports as well as your own.

Electrification

As the product line electrifies, the carbon in making it becomes the visible number. Green power and green heat cut it where it is measured — on the plant meter.

Carbon markets

India's Carbon Credit Trading Scheme sets emission-intensity targets sector by sector. Plants that measure now are ready when their sector or supply chain is covered.

The ecosystem / first of its kind

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.

01

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.

02

Heat pumps

Every kWh in becomes three to four kWh of useful heat. The boiler stops burning fuel for loads up to 120 °C.

03

Thermal storage

Heat is made when power is cheapest and greenest, and used when the process needs it.

04

ergOS

Meters power, steam, fuel and water every 15 minutes; forecasts, schedules and trades; runs heat pumps against price.

05

esgOS

Converts the same metered data to Scope 1, 2 and 3, BRSR Core-format, CBAM, CDP and customer disclosures.

Why the order matters. A heat pump on grid power cuts fuel cost but, at today's grid emission factor, barely cuts carbon against gas. Put the same heat pump on green power and its heat is close to zero-carbon. Power first, then heat — from one provider.

Heat pump 101 / the question clients ask most

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.

What goes in, what comes out

Fuel boiler
in · 1 kWh fuel
out · 0.85 kWh heat
Heat pump
in · 1 kWh power + 2.5 free
out · 3.5 kWh heat

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

~5COP at 30 K lift
~3.5COP at 50 K lift
~2.5COP at 70 K lift
~2COP at 90 K lift

Lift = delivery temperature minus source temperature. Recovering warm waste heat first and delivering no hotter than the process needs keeps the COP high.

Does it replace my boiler?

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.

What if power is expensive?

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.

What does the site need?

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.

Is it proven?

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.

Layer 02 / heat

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 power 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.

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.
