Number of Machines/Production Lines

Production Equipment

Total number of machines, production lines, or major equipment you want to monitor. Each typically requires 1 monitoring point.

Typical: 5-50 machines

Power Consumption Per Machine (kW)

Machine Power Rating

Average power draw per machine in kilowatts (kW). Check equipment nameplates or use power meter readings. Include motors, controls, and auxiliary equipment.

Typical: 20-100 kW per machine

Production Hours Per Day

8 hours (1 shift), 16 hours (2 shifts), 24 hours (3 shifts)

Days Per Week

Typical: 5-6 days (Mon-Sat), 7 days (continuous)

Electricity Rate ($/kWh)

PLN Industrial Tariff

Your current electricity cost per kilowatt-hour. Check PLN bill. Indonesia I-4 industrial tariff: ~Rp 1,400-2,000/kWh (~$0.09-0.13/kWh). Include all charges (energy, capacity, VAT).

Indonesia typical: $0.09-0.13/kWh (Rp 1,400-2,000/kWh)

Current Power Factor

Power Factor (PF)

Measure of electrical efficiency. Check your PLN bill for kVArh charges. PF < 0.85 incurs penalties. Typical uncorrected: 0.70-0.80. With capacitors: 0.90-0.95.

PLN Penalty Zone (< 0.85)

Idle Time (% of production hours)

Idle Waste

Percentage of time machines are powered on but not producing (lunch breaks, material waiting, changeovers). Typical: 20-40%. Major energy waste opportunity!

Typical: 20-40% (lunch, material wait, changeovers)

Maintenance Downtime (hours/week)

Scheduled maintenance/cleaning time
