Based on actual operating conditions, the purely electric SC210EV demonstrates overwhelming economic and environmental advantages over traditional 21-ton diesel excavators.
Under identical working conditions, the power cost of the SC210EV (equipped with a 55 kW electric motor) is 68% to 81% lower than that of traditional diesel models.
Fuel vs. Electric: Hourly Operating Cost Comparison
When analyzing the Total Cost of Ownership (TCO) for heavy machinery, energy consumption is the largest ongoing expense. Here is how the hourly costs break down:
21-Ton Diesel Excavator: Powered by a Cummins engine with a fuel consumption of 15–18 L/h. At a diesel price of $0.97 USD/L, the hourly fuel cost reaches $14.49 – $17.39 21USD .
21-Ton Electric Excavator SC210EV: Consumes only 20–40 kWh/h. Even calculated strictly at the peak electricity rate of 1 RMB/kWh ($0.138 USD/kWh), the hourly power cost is only $2.76 – $5.52 USD .
Pro Tip for Regional Charging: In regions with lower electricity rates or during off-peak hours (e.g. $0.069 USD/kWh), your operational costs will be cut in half, further maximizing your profit margins.
Savings per Hour: $11.73 – $11.87 USD
Savings per Day (10-hour shift): $117.30 – $118.68 USD
Savings per Month (25 working days): $2,932.50 – $2,967.00 USD
Savings per Year (12 working months): $35,190.00 – $35,604.00 USD
Section Summary: By eliminating diesel, the SC210EV instantly slashes your hourly energy bills by up to 81%, translating to over $35,000 USD in direct annual fuel savings alone.
Disruptive Zero-Maintenance Advantage: Eliminate Engine Service Costs
The purely electric SC210EV completely eliminates the tedious and expensive routine engine maintenance required by diesel fleets. Thanks to the total removal of the internal combustion engine system, you say goodbye to replacing fuel filters, oil filters, air filters, water separators, and engine oil.
Based on a standard high-intensity annual operation of 3,000 hours (servicing every 250 hours, totaling 12 maintenance cycles per year):
Zero Maintenance Consumables Cost: A traditional 21-ton diesel excavator costs approximately $298.51 USD (2,000 RMB) per single engine service. The cumulative annual cost for 12 services reaches $3,582.09 USD (24,000 RMB).
Zero Routine Labor Cost: Each engine service for a diesel model requires 2 labor hours (at $8.96 USD / 60 RMB per hour), totaling $17.91 USD (120 RMB) per service. The cumulative annual labor cost reaches $214.93 USD (1,440 RMB).
Section Summary: Beyond fuel, the electric powertrain removes complex moving parts. Solely on engine maintenance and labor, the SC210EV puts an extra $3,797.01 USD (25,440 RMB) back into your pocket every year.
By combining Energy Savings with Maintenance & Labor Savings, the SC210EV delivers an unparalleled return on investment.
Total Annual Savings=$38,059.70 (Energy)+$3,797.01 (Maintenance)=$41,856.71 USD
Total Annual Combined Savings: Nearly $41,791 USD (280,000 RMB) saved directly per unit every single year.
In the international market, a traditional 21-ton diesel excavator is priced at approximately $54,000+ USD, while the flagship electric SC210EV carries an official guide price of around $64,000+ USD.
Although the upfront procurement cost of the electric excavator is $10,000 USD higher, its staggering comprehensive saving capability means you will fully offset the price difference in just about 3 months of actual operation!
Summary:
3-month payback period makes the SC210EV a phenomenal productivity tool. After the initial 90 days, every dollar saved converts directly into pure profit for your business while driving a green, low-carbon fleet transformation.
