KSM to cold chain/ where we intervene
Every utility
has a lever.
Starting materials arrive, reactors run, dryers and cleanrooms hold spec, water loops stay hot, packs leave in the cold chain. jouleWise acts at ten points — in the electricity supply and the utility block, never inside the validated process.
Green sourcing
Intrastate and ISTS solar and wind contracted through open access for a flat, round-the-clock load.
ElectricityConnectivity and metering
Open access approvals, connection agreement and ABT metering at the site incomer.
ElectricityRooftop solar
Warehouse and admin roofs carry behind-the-meter solar, sized from measured load.
ElectricityBattery storage
LFP storage for peak shaving and ride-through on critical HVAC and water systems.
ElectricityHeat pumps on jacket and water loops
Hot water for reactor jackets and utility loops made by heat pumps instead of boiler steam.
HeatCleanroom HVAC reheat
AHU reheat and dehumidification coils fed from the heat pump hot-water circuit.
HeatHot-water store and PW loop
Thermal store charged in solar blocks; purified-water loop held at sanitisation temperature.
HeatChiller heat recovery
Heat that cooling towers throw away becomes the heat pump source — cooling and heating from one kWh.
HeatergOS control
15-minute metering of electricity, heat, chilled water, fuel and water; forecasting, trading and heat dispatch.
Data · ergOSSuppliers and customers

Low-cost
green electricity.
Cleanroom HVAC, chillers and water systems run 24×7, so the load is high and flat. That suits round-the-clock wind and storage — and heat pump load can still be concentrated into solar hours with a hot-water store.
Hover the profile to read any 15-minute block
Cleanroom HVAC never stops, so the base is nearly flat. The heat pumps carry purified-water heating, sanitisation and HVAC reheat all day, with batch peaks in the morning and afternoon campaigns.
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.
Much pharma heat is warm, not hot: jacket loops, dryer air, HVAC reheat, washing and purified-water sanitisation sit below 120 °C. Heat pumps serve those loads on electricity — and the chilled-water plant next door becomes their heat source.
Heat sources we reuse
Chiller condensers and cooling-tower return, HVAC exhaust air, solvent-recovery condensers and warm effluent — heat the site already rejects.
Heating and cooling at once
Pharma sites cool and heat at once: chilled water for reactors and cleanrooms, reheat and hot loops alongside. A heat pump on the chilled-water return 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/ 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 3.2 reflects hot water near 80 °C for jacket and water loops, drawn from the chilled-water return (heating side only; the cooling delivered is extra); 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/ Pharmaceuticals
The Pharmaceuticals playbook is jouleWise's typical engineering approach for pharma and API plants: heating and cooling at the same time.
One provider for green electricity, green heat and the data that proves both — from reactor jackets to cleanroom HVAC to the cold chain. For an API, formulation or CDMO site, the carbon in the product is now part of the commercial conversation. Six pressures point at the same metered data. Much pharma heat is warm, not hot: jacket loops, dryer air, HVAC reheat, washing and purified-water sanitisation sit below 120 °C. Heat pumps serve those loads on electricity — and the chilled-water plant next door becomes their heat source.
What to take away
