Power Consumption and Operating Cost Comparison: Electric vs Diesel Excavators (210 Class)
1️⃣ Electric Excavator Power Consumption (Typical Range)
Excavators in the 20–22 ton class (Model 210) generally use electric motors in the range of:
| Motor Size | Typical Power Draw During Work | Remarks |
| 110 kW Motor | 20–25 kWh per hour | Light to medium duty work |
| 132 kW Motor | 22–28 kWh per hour | Normal excavation duty |
| 160 kW Motor | 25–32 kWh per hour | Heavy duty operation |
| 200 kW Motor | 28–35 kWh per hour | High load continuous work |
⚠️ Important:
Electric motors are rarely loaded at 100%. In hydraulic excavators, average load is typically 20–35%, which is why real electricity consumption remains relatively low.
For a 210 excavator, the realistic consumption is approximately:
25 kWh per hour
💡 Electricity Operating Cost
Calculation
Electricity consumption per hour:
25 kWh × ₹10 per unit = ₹250 per hour
Electric Excavator Cost = ₹250/hour
⛽ Diesel Excavator Operating Cost
Typical diesel consumption for a 210 excavator:
15 litres per hour
Calculation
15 litres × ₹100 per litre = ₹1,500 per hour
Diesel Excavator Cost = ₹1,500/hour
📊 Real Operating Cost Comparison
| Parameter | Electric Excavator | Diesel Excavator |
| Energy Consumption | 25 kWh | 15 Litres |
| Cost per Unit | ₹10 | ₹100 |
| Cost per Hour | ₹250 | ₹1,500 |
| Maintenance | Very Low | High |
| Emissions | Zero | High |
| Noise | Very Low | High |
💰 Hourly Savings
₹1,500 − ₹250 = ₹1,250 savings per hour
Daily Savings
(8 hours operation)
₹1,250 × 8 = ₹10,000 per day
Monthly Savings
(26 working days)
₹10,000 × 26 = ₹2,60,000 per month
⚡ Dual Mode Advantage (Electric + Diesel)
One of the biggest advantages of conversion is dual operating flexibility.
The excavator can operate:
✔ Electric Mode – When grid power is available
✔ Diesel Mode – When working at remote sites
Benefits of Dual Mode
• No work stoppage due to power availability
• Maximum fuel savings when electricity is available
• Flexibility for construction and mining sites
• Backup power always available
• Extended engine life due to reduced diesel usage
This combination provides the best of both technologies.

• Longer machine life
Industries such as mining, port handling, scrap yards, and construction are rapidly shifting toward electric equipment to reduce operational costs.
✅ Conclusion
Converting a 210 excavator to electric drive can reduce operating costs from ₹1,500/hour (diesel) to around ₹250/hour (electric).
This means:
✔ Massive savings
✔ Cleaner operation
✔ Lower maintenance
✔ Higher efficiency
With dual-mode capability (Electric + Diesel), machines remain flexible for both industrial and remote job sites.
