Introduction
An LPG bottling plant in Port Blair, operating under a leading petroleum refinery, plays a vital role in energy distribution across the region. With continuous operations involving compressors, pumps, and cylinder handling systems, energy consumption forms a significant portion of operational costs.
To improve energy efficiency, reduce costs, and align with sustainable practices, the plant engaged Elion Technologies & Consulting Pvt. Ltd. to conduct a detailed energy audit. The objective was to identify inefficiencies, establish a baseline, and recommend actionable energy-saving measures.

- Load profiling and demand analysis
- Identification of peak consumption patterns
2. Equipment Inventory & Assessment
- Air compressors and compressed air systems
- Pumps and motor-driven systems
- Lighting systems (indoor & outdoor)
- HVAC and auxiliary systems
3. Measurement & Monitoring
- On-site measurements using power analyzers
- Voltage, current, power factor, and harmonics analysis
- Compressed air leak detection
4. Standards Referenced
- ISO 50002 – Energy Audits Standard
- OISD Guidelines – Energy management in oil & gas sector
Energy Use Baseline
The baseline energy consumption was established to identify major energy-consuming systems:
| System | Annual Consumption (kWh) | Energy Cost (₹) | % Contribution |
|---|---|---|---|
| Air Compressors | 1,200,000 | 96,00,000 | 40% |
| Pumps | 750,000 | 60,00,000 | 25% |
| Lighting | 300,000 | 24,00,000 | 10% |
| HVAC Systems | 450,000 | 36,00,000 | 15% |
| Others | 300,000 | 24,00,000 | 10% |
Key KPI
- Energy Consumption per Cylinder Filled: 0.85 kWh/cylinder
Energy Saving Opportunities
Several opportunities were identified to optimize energy consumption:
| Measure | Energy Saving (%) | Annual Savings (kWh) | Investment (₹) | Payback Period |
|---|---|---|---|---|
| Compressor leak reduction | 8% | 96,000 | 5,00,000 | 6 months |
| VFD installation on pumps | 10% | 75,000 | 8,00,000 | 10 months |
| LED lighting upgrade | 50% | 150,000 | 4,00,000 | 8 months |
| Power factor improvement | 3% | 36,000 | 2,50,000 | 6 months |
| Heat recovery system | 5% | 60,000 | 6,00,000 | 12 months |
Implementation & Results
Following implementation of key recommendations:
- Total Energy Savings: ~417,000 kWh annually
- Cost Savings: ₹33–35 Lakhs per year
