Electricity figures are reported commercial and industrial client impact in the first year of ergOS; results vary with state, tariff structure and load profile. The project figure is renewable-energy study scope, not capacity built.
What we change/ two levers
Two levers. Use one or both.

Each lever pays for itself. Start with electricity or heat. Together, cheap green electricity makes heat-pump heat both cheaper and near-zero carbon.

Track record/ RE-100 assignments
Trusted by industry leaders. 30 plants in 8 states.
Renewable-energy study mandates: size, location, savings and NPV of solar, wind and storage. Capacity studied, not capacity built — how we handle results.
In short/ Home
jouleWise designs, finances, builds and operates the electricity and heat systems that cut an industrial plant's energy cost and bring it closer to net zero.
Two levers, taken separately or together. Electricity: solar and wind through rooftop and open access, battery storage for peaks and evening shifts, and ergOS buying and scheduling every 15 minutes — up to 25% lower electricity cost and up to 65% of electricity from solar and wind. Heat: industrial heat pumps to 120 °C, waste-heat recovery and thermal storage, so process heat costs at or below today's fuel and is close to zero-carbon on green electricity. jouleWise can fund either lever: capex, ESCO shared savings, Heat-as-a-Service or Electricity-as-a-Service. One contract covers design, finance, implementation and operation, and jouleWise stands behind the savings. Engagements start with a four-week energy assessment on one plant.
What to take away
Electricity lever: up to 25% lower electricity cost vs grid tariff and up to 65% of your electricity from solar & wind, reported C&I client impact in year one of ergOS; results vary with state, tariff structure and load profile.
Heat lever: industrial heat pumps make hot water and low-pressure steam up to 120 °C, deliver three to four units of heat per unit of electricity, and cost at or below today's fuel per unit of heat; on contracted green electricity the heat is close to zero CO₂.
Most process heat in food and beverages (60–95 °C), pharmaceuticals (50–90 °C), textiles (60–100 °C), chemicals (60–120 °C) and automotive components (40–90 °C) is below 120 °C — the range that can be electrified today.
Four ways to buy: capex (you own the assets and keep 100% of savings), ESCO (jouleWise invests and is paid from measured savings), Heat-as-a-Service (per unit of heat at or below fuel cost, or a fixed monthly fee) and Electricity-as-a-Service (per unit of electricity below grid tariff).
Illustrative mid-size plant using 10 million kWh of electricity and 2 million kWh of heat a year: energy cost falls from about ₹9.74 Cr to ₹7.62 Cr with electricity only, ₹8.78 Cr with heat only and ₹6.65 Cr with both — about 32% lower, with about 5,090 t less CO₂ a year.
ergOS meters, forecasts and controls electricity and heat every 15 minutes; esgOS turns the same data into audit-ready carbon reporting: Scope 1, 2 and 3, BRSR Core-format, CBAM and CDP.
jouleWise Advisory Services Pvt Ltd is based in Noida, India, with a presence in Spain, holds ISO 9001:2015 and ISO 27001, and has about 1 GW of renewable-energy study scope across RE-100 assignments.
Questions this page answers
What does jouleWise do?
It designs, finances, builds and operates the electricity and heat systems that cut an industrial plant's energy cost and emissions: cheaper, greener electricity, and process heat without burning fuel.
Do I have to take both electricity and heat?
No. Each lever works on its own and pays for itself. Together, cheap green electricity makes heat-pump heat both cheaper and near-zero carbon.
Do we need to invest?
Not necessarily. jouleWise can fund it: under ESCO it invests and is paid from measured savings; under Heat-as-a-Service or Electricity-as-a-Service you pay per unit. Capex is available if you prefer to own the assets.
Who is accountable for the result?
jouleWise, under one contract from design to daily operation, with no hand-offs between consultant, contractor, financier and operator. It stands behind the savings.
How does it start?
Share twelve months of electricity and fuel bills for one plant. A four-week energy assessment — data, site visit, heat metering, savings and carbon baseline — is followed by a proposal for electricity, heat or both, then implementation from about three months.
Data, site visit, heat metering, savings and carbon baseline — for electricity and heat.
Weeks 4–8
Proposal
Electricity, heat or both: solution design, business case and financing model.
From ~3 months
Implementation
We build and operate — each lever on its own timeline.
Share 12 months of electricity and fuel bills for one plant. We’ll show what you can save on electricity, on heat, or both — in rupees and in tonnes of CO₂.
