Power Supply Solution for Construction Sites at High-Altitude & Cold Regions

Power Supply Solution for Construction Sites at High-Altitude & Cold Regions: Diesel-ESS Smart Power Station Delivers Higher Efficiency and Stable Power

1. Project Background

This highway project is located deep in the Kunlun Mountains, Xinjiang, with an operating altitude of 5,400m to 5,800m. The site features extreme cold and harsh natural conditions, without access to the utility grid. The concrete batching plant has fluctuating load demand. Conventional diesel generators suffer from power derating, soaring fuel consumption and frequent breakdowns at high altitudes, making it difficult to guarantee continuous and stable power for construction.

2. Solution: Diesel-ESS Smart Power Station

The containerized diesel-energy storage smart power station adopts intelligent coordination between diesel generators and energy storage systems:

Energy storage absorbs impact loads from the batching plant startup & shutdown. Diesel generators run steadily at high-efficiency working points and avoid frequent on-off cycles, reducing equipment degradation under thin high-altitude air.

Integrated container design with temperature control system adapts to frigid temperatures and strong sandstorms, ensuring stable operation of batteries and electrical controls in extreme cold environments.

Intelligent EMS energy management system optimizes power output automatically. The power generation efficiency of diesel is improved: 2 kWh per liter for conventional diesel generators vs. 3 kWh per liter for the smart power station.

3. Cost-benefit Analysis

Average load power: 1183 kW; daily working hours: 14h; 27 working days per month; project duration: 12 months; total power consumption: 5.366 million kWh

4. Key Benefit:

Under the same total power consumption, fuel cost savings reach 6.26 million CNY. Even after considering the rental difference between smart power stations and conventional diesel gensets, the overall fuel-saving benefit remains substantial.

5. Value Summary:

For off-grid infrastructure projects at high-altitude, frigid and remote sites, the diesel-ESS smart power station provides efficient, stable and flexible power supply for concrete batching plants and heavy construction equipment. It addresses the pain points of conventional diesel gensets including power shortage and unstable power supply on plateaus, greatly cuts fuel expenditure and reduces exhaust emissions for local eco-environment protection. It is the preferred off-grid power solution for large plateau engineering projects.
