CARBON × KAIZEN · Carboka practice lab
Electricity is the digital footprint of equipment
Select a state to explore its power signature. Start with measurement and connect energy to the production context.
Production
What the curve suggests
Load varies with process cycles. Combine orders, cycle timing and good counts to understand energy per product.
What to check at the production site
Align product specifications, processing requirements and complete energy; plan improvement trials with suppliers.

ROI+E: use improvements that are confirmed within a consistent boundary and can actually be realized when assessing costs and payback.
Calculations and boundaries
This is an illustrative curve, not measured data or equipment specifications. Power (kW) accumulated over time gives energy (kWh). Product, good output and a complete measurement boundary are still needed to compare energy per unit. A curve alone cannot diagnose faults or prove carbon reductions.
Measure directly where possible. Use models for what cannot be measured directly, and retain assumptions and review records.
Based on whitepaper page 11, “Electricity is the digital footprint of equipment.” Interactive explanations extend the website teaching examples.
ROI+E: confirm achievable savings before calculating the payback period.
Bring investment, annual benefits and recurring costs together. See what happens to payback when fewer benefits materialize.

01 Adjust the scenario
EX05: initial investment NTD 300,000, annual net benefit NTD 50,000, simple payback 6 years. All amounts are teaching assumptions. This page adds benefit realization and period ROI for scenario comparison.
Inputs are calculated on this page only. They are not uploaded or saved automatically. Reloading restores the example.

Carbon-price scenario (separate from cash benefits)
— · —
Calculated as entered avoided energy × factor / 1,000 × internal carbon price. No current factor is assumed; this is not carbon-credit revenue. It uses the full energy assumption without applying cash-benefit realization.
Calculations and boundaries
Annual net cash savings = (avoided electricity consumption × electricity price + maintenance cost savings + scrap cost savings) × benefit realization rate − additional operating costs. Simple payback period = initial investment / annual net cash savings. Period ROI = (annual net cash savings × number of years − initial investment) / initial investment. Annual savings are assumed constant. Taxes, financing, discounting, residual value, price changes and electricity demand charges are excluded.
03 Put it into practice
Check that each benefit is realizable and not double-counted. Extra output becomes a cash benefit only when sellable and net of additional costs. Assess customer trust, safety and resilience separately. Verify avoided energy through a measurement plan before revising the investment decision.
