Diesel-Storage Smart Power Station Bridge Pile Foundation Construction Application Scenario

1. Project Background:

A highway bridge pile foundation project is located in a complex terrain area, featuring mountains, rivers, existing highways, communication lines, and high-voltage power lines. External grid connection is extremely difficult, and overhead or buried cable routing is costly and impractical.

2. Key power demand characteristics:

High total power consumption, with overlapping operation of high-power equipment such as pile drivers, demanding robust load capacity;

The site adopts a diesel-storage hybrid smart power station (diesel generator + energy storage) as an alternative to conventional standalone diesel generator sets.

3. Smart Power Station Configuration:

Configuration: 2 × 200 kW diesel generators + 1 energy storage system

4. Load & Consumption Data:

Item	Value
Average load power	315.9 kW
Hourly energy consumption	315.9 kWh
Daily operating hours	12 h
Daily energy consumption	3,790.8 kWh
Monthly working days	28 days
Monthly energy consumption	106,100 kWh (≈106.1 MWh)
Construction period	12 months
Total energy consumption over project	1,273,700 kWh (≈1,273.7 MWh)

5. Fuel Consumption & Cost Comparison (Diesel price: 7 RMB/L)

Metric	Conventional diesel-only	Diesel-storage smart station
Diesel generation efficiency	1.7 kWh/L	2.5 kWh/L
Total diesel required over project	749,000 L	509,000 L
Total diesel expenditure	5.245 million RMB	3.566 million RMB

6. Benefits Summary

Under identical total energy consumption:

The diesel-storage smart station saves 1.678 million RMB in diesel costs compared to conventional diesel-only generator sets;
Even after deducting the rental cost differential between the smart station and traditional diesel gensets, the customer's fuel savings remain substantial;
It also resolves the pain point of difficult external power line deployment in remote mountain construction sites, making it ideal for field high-power operations such as bridge pile foundation works.

7. Scenario Value Proposition

Applicable scenarios: Mountainous / remote bridge pile foundation projects without reliable grid access and with multiple routing obstacles
Core advantages: The energy storage system optimizes diesel engine operating conditions, improves fuel-to-power efficiency, and significantly reduces diesel consumption and fuel costs; containerized modular diesel-storage units enable rapid on-site deployment without extensive external grid construction.
