Introduction
Sugar mills are among the most energy-intensive industrial facilities, relying heavily on steam, electricity, and thermal systems for continuous operations. In a competitive market where margins are tight, optimizing energy consumption becomes critical for improving profitability and sustainability.
In this case, a sugar mill in Kushinagar, Uttar Pradesh engaged Elion Technologies to conduct a comprehensive energy audit aimed at identifying inefficiencies, reducing operational costs, and enhancing overall energy performance.
Audit Scope & Methodology
Elion conducted a comprehensive, standards-driven energy audit following globally recognized frameworks and Indian standards.
Data Collection Approach
- Analysis of historical utility bills (electricity & fuel)
- Review of operational logs and production data
- On-site measurements across key systems
- Load profiling and demand pattern analysis
Instruments Used
- Portable Energy Analyzer (for real-time electrical parameters)
- Clamp Meters (current measurement across feeders)
- Infrared Thermography (for heat loss detection)
- Flow meters and temperature sensors
Standards & Guidelines Followed
- ISO 50002 – Energy Audit Standard
- IS 14489 – Energy Audit Code of Practice
- ECBC (Energy Conservation Building Code) – where applicable
👉 These standards ensure accuracy, reliability, and actionable insights in audit findings.
Energy Consumption Baseline
A detailed baseline was established to understand energy distribution across major systems.
Annual Energy Consumption Summary
| System | Annual Energy Use (kWh) | Annual Cost (₹) |
|---|---|---|
| Boilers & Steam Generation | 18,50,000 | ₹1.85 Cr |
| Steam Distribution Losses | 4,20,000 | ₹42 Lakhs |
| Motors & Drives | 12,75,000 | ₹1.27 Cr |
| Pumps & Utilities | 6,10,000 | ₹61 Lakhs |
| Lighting Systems | 2,40,000 | ₹24 Lakhs |
| Total | 44,00,000 kWh | ₹4.39 Cr |
Savings Opportunities Identified
The audit revealed multiple high-impact energy-saving opportunities with strong financial returns.
Recommended Measures & Impact
| Measure | Expected Savings | Investment (₹) | Payback |
|---|---|---|---|
| Boiler Insulation Upgrade | 8% (~1,48,000 kWh) | ₹6 Lakhs | 8 months |
| Condensate Recovery System | 10% (~1,85,000 kWh) | ₹10 Lakhs | 10 months |
| Variable Frequency Drives (VFDs) | 12% (~2,20,000 kWh) | ₹18 Lakhs | 12 months |
| Power Factor Correction | 5% (~90,000 kWh) | ₹4 Lakhs | 6 months |
| LED Lighting Retrofit | 60% (~1,44,000 kWh) | ₹5 Lakhs | 9 months |
