Energy Consumption Log

Energy Consumption Log

A daily energy tracking log for dairy plant utility managers and engineers. Essential for energy audits, cost allocation, and identifying efficiency improvement opportunities.

Parameters Tracked

Electricity

• Total plant kWh (main meter reading — start and end of shift)
• Production area sub-meter reading
• Refrigeration sub-meter reading
• Utilities (boiler, compressed air, water treatment)
• Specific energy: kWh per litre of milk processed

Steam / Boiler

• Steam meter reading (kg) or boiler water feed meter
• Fuel consumed (kg coal / litres HFO / m³ gas)
• Specific steam consumption: kg steam per litre processed
• Specific fuel consumption: kg fuel per kg steam
• Boiler efficiency (calculated or measured)

Water

• Total water inlet meter (m³)
• Process water (pasteurizer, CIP)
• Cooling tower make-up
• Boiler feed water
• Effluent meter reading (m³)
• Specific water consumption: litres water per litre milk

Compressed Air

• Compressor run hours
• Air receiver pressure (start/end)
• Estimated flow (m³/hr if meter available)

Refrigeration

• Compressor run hours
• Suction pressure and discharge pressure
• Chilled water outlet temperature
• Cooling load achieved (approximate TR)

Production Reference

• Total milk processed (litres)
• Product mix (fluid milk, SMP, paneer, etc.)
• Shift duration (hours)

How to Use This Log

1. Record meter readings at start and end of each shift
2. Calculate shift consumption = end reading − start reading
3. Divide by litres processed to get specific consumption KPIs
4. Compare to previous shift and weekly average
5. Investigate any day where consumption exceeds baseline by > 10%
