## In short

One provider for green electricity, green heat and the data that proves both — from source water to CIP to the last case on the truck. For a bottler or beverage maker, carbon, water and plastic are now scored per litre by brand owners, retailers and regulators. Six pressures point at the same metered data. Almost every heat duty in a beverage plant sits below 100 °C: CIP, washing, syrup and pasteurisation. Heat pumps serve them on electricity — and the chillers cooling the product supply the heat.
## Chill it, heat it — on the same kWh.

- **The situation.** A beverage plant cools and heats all day: chillers for carbonation, syrup and cold rooms; hot water for CIP, bottle washing, syrup and pasteurisation, mostly from PNG, diesel or biomass boilers. Blow moulders and compressors add a heavy electricity load. Brand owners and franchise partners set renewable and emission targets for their bottling network, and plastic EPR adds another annual filing.
- **The gap.** Electricity, 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 low-cost electricity; 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: <b>green electricity</b> — intrastate and ISTS solar and wind, rooftop solar, BESS and green-market purchase, each source orchestrated to fulfil industrial demand at least cost; <b>ABT metering and data loggers</b> on every source and load; <b>green heat</b> from industrial heat pumps up to 120 °C; <b>ergOS</b> to meter and orchestrate both every 15 minutes; <b>esgOS</b> to turn the same data into audit-ready disclosure.
- **Why it compounds.** Low-cost green electricity 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 electricity cost on DISCOM tariff and up to 65% renewable share (reported, year 1 of ergOS). Heat pumps on the chiller loop then deliver CIP, washing and pasteuriser hot water from heat the plant already rejects.
- **How to engage.** Four models, mix and match: <b>Advisory</b>, <b>SaaS</b> (ergOS + esgOS), <b>Heat Advisory</b>, and <b>Heat as a Service</b>, where you pay per unit of heat and invest nothing upfront.
- **First step.** A four-week decarbonisation baseline on one plant: electricity bills, load survey, fuel records and portable heat metering on CIP, bottle washing and pasteurisation — ending in one business case for electricity, heat and ESG.

## Why now: Your brand owner counts every litre.

For a bottler or beverage maker, carbon, water and plastic are now scored per litre by brand owners, retailers and regulators. Six pressures point at the same metered data.

- **Brand-owner targets.** Brand owners and franchise partners set renewable and emission targets for their bottling network and ask for metered proof, plant by plant.
- **Plastic EPR.** Plastic Waste Management rules set EPR and recycled-content obligations on PET packaging, tracked and filed every year.
- **Water.** Water-use ratio and groundwater permits are licence-to-operate issues for bottlers — and belong on the same data platform as energy.
- **Energy cost.** Chilling, compressed air, blow moulding and hot water for CIP and washing — and summer peaks that push every one of them up.
- **Disclosure.** BRSR Core-format reporting and value-chain disclosure put your energy, water and plastics in customers' reports as well as your own.
- **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 intervention map: Every litre has a lever.

Water is treated, syrup is made, bottles are washed, filled, pasteurised and chilled, and cases leave for the market. jouleWise acts at eleven points across the plant.

1. **Green sourcing** (power, Electricity). Intrastate and ISTS solar and wind contracted through open access for a long-shift load with summer peaks.
2. **Connectivity and metering** (power, Electricity). Open access approvals, connection agreement and ABT metering at the plant incomer.
3. **Rooftop solar** (power, Electricity). Bottling hall and warehouse roofs carry behind-the-meter solar, sized from measured load.
4. **Battery storage** (power, Electricity). LFP storage shaves the blow-moulding and chiller peak and carries solar into the evening shift.
5. **Heat pumps on CIP and syrup** (heat, Heat). CIP, syrup dissolving and process hot water from heat pumps instead of boiler steam.
6. **Pasteuriser and bottle washer** (heat, Heat). Tunnel pasteuriser zones and washer baths on the heat pump hot-water circuit.
7. **CIP and hot-water store** (heat, Heat). Store charged in solar blocks, ready for every CIP cycle and changeover.
8. **Chiller heat recovery** (heat, Heat). Carbonation and process-chiller heat becomes the heat pump source — chilling and hot water from one kWh.
9. **ergOS control** (data, Data · ergOS). 15-minute metering of electricity, heat, chilled water, fuel and water — per line where it matters.
10. **Outbound and packaging** (esg, ESG · esgOS). Carbon per litre and per case, plastic EPR returns and recycled-content tracking from esgOS.
11. **Source water** (esg, ESG · esgOS). Water withdrawal by source, water-use ratio and groundwater compliance, metered and reported.

## Green electricity: Low-cost green electricity.

Blow moulders, compressors, chillers and filling lines run long shifts with a daytime peak — and demand climbs steeply in summer. We build the green portfolio to that profile and move heat pump load into solar hours.

- **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. Outcome: RE-100 roadmap · size, location, savings, NPV
- **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. Outcome: Green electricity contracted · ~3 months once planning closes
- **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. Outcome: Every source and load visible in 15-minute blocks
- **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. Outcome: For the life of the assets

## Heat: The boiler, reinvented.

Almost every heat duty in a beverage plant sits below 100 °C: CIP, washing, syrup and pasteurisation. Heat pumps serve them on electricity — and the chillers cooling the product supply the heat.

| Duty | Temperature | Heat pump? |
|---|---|---|
| Bottle washing (returnable glass, caustic baths) | 60–85 °C | yes |
| CIP of syrup and filler lines (hot caustic and rinse) | 70–85 °C | yes |
| Syrup dissolving (sugar and ingredients) | 60–85 °C | yes |
| Tunnel pasteurisation (packed product) | 60–75 °C | yes |
| Hot fill and flash pasteurisation (juices, teas, dairy drinks) | 72–95 °C | yes |
| Crate and case washing (returnable logistics) | 50–70 °C | yes |
| UHT processing (remains on existing steam) | 135–145 °C | stays on fuel |

- **Heat sources we reuse.** Carbonation, process and cold-room chiller condensers, compressor heat and warm rinse water — heat the plant already rejects every hour it runs.
- **Heating and cooling at once.** Beverage plants chill product while heating CIP and wash water. A heat pump on the chiller loop serves both from the same kWh.
- **Sized from metered heat.** Portable heat meters log flow and temperature on candidate processes for two to four weeks before anything is sized.

## Economics: 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.

| Route | ₹ per kWh of useful heat | kg CO₂ per kWh-th |
|---|---|---|
| PNG-fired boiler (₹55/SCM · 85% efficiency) | 6.22 | 0.221 |
| Diesel (HSD) boiler (₹90/L · 85% efficiency) | 10.59 | 0.315 |
| Heat pump on DISCOM electricity (₹8.5/kWh · COP 3.6) | 2.36 | 0.199 |
| Heat pump on green open access (₹5.5/kWh landed · COP 3.6) | 1.53 | 0.000 |
| Heat pump in solar blocks + store (₹4.0/kWh · COP 3.6) | 1.11 | 0.000 |

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 3.6 reflects hot water near 80 °C for CIP and washing, drawn from the carbonation and process chiller loop; COP falls as delivery temperature rises. Tariffs, fuel prices and COP vary by site and are replaced with metered values in the baseline.

## Roadmap: Baseline. Electricity. Heat. Proof.

1. **Baseline** (Weeks 1–4). Bills, load survey, fuel and steam records, portable heat metering on candidate processes, ESG data map. Outcome: Signed-off energy, heat and carbon baseline
2. **Roadmap** (Weeks 4–8). RE-100 electricity plan, heat pump shortlist for CIP, washing and pasteurisation, and the ESG data map — in one business case. Outcome: One business case — electricity, heat, ESG
3. **Meter and log** (Weeks 6–12). ABT metering at the incomer and data loggers on electricity, heat, fuel and water lines — the measured base every later step is sized, settled and reported on. Outcome: ergOS live on metered data
4. **Electricity live** (~3 months after roadmap). Open access contracted and approved; rooftop solar and BESS where they fit; every source orchestrated against demand on ergOS. Outcome: Green electricity flowing
5. **Heat live** (Pilot, then scale). One heat pump on the chiller loop with a CIP hot-water store, metered on ergOS; then washers, pasteurisers and syrup. Outcome: Fuel displaced, measured on ergOS
6. **Operate and disclose** (Every block · every year). ergOS runs electricity and heat; esgOS publishes BRSR Core-format, CBAM, CDP and customer disclosures with an audit trail. Outcome: Assurance-ready numbers

Timelines indicative; confirmed after the baseline and dependent on state approvals and equipment lead times.

## 24-hour dispatch

Heat pumps run all day here: CIP and washer water at every changeover, the pasteuriser through both shifts, the hot-water store charged in solar hours. Chillers carry on through the night, which is why the base never falls far.

## Questions and answers

**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 electricity is expensive?**  
Each kWh of electricity returns three to four kWh of heat, so heat costs roughly a third of the electricity 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.
