Construction projects often require temporary power that can be deployed and relocated as work progresses. A diesel-battery hybrid mobile energy system can provide flexible power support while reducing diesel generator load, fuel consumption, and operating noise.
Building Flexible and Efficient Mobile Energy Systems for Temporary Power Needs
Urban development, infrastructure construction, and large-scale engineering projects are typically characterized by short construction cycles and frequent changes in work locations, resulting in high demand for temporary power. However, the construction of fixed power distribution facilities involves long lead times and high costs, making it difficult to meet the need for rapid project commencement.
Although traditional diesel generators can provide power for construction sites, long-term operation presents issues such as high fuel consumption, excessive noise, high emissions, and frequent maintenance. As urban development places increasingly stringent requirements on green construction and low-noise operations, traditional power supply methods are no longer sufficient to meet the demands of modern engineering projects.
To address the need for flexible power supply in construction scenarios, YUNT offers a diesel-storage hybrid mobile power supply solution. By coordinating the operation of energy storage systems, diesel generators, and intelligent control systems, this solution provides construction sites with efficient, reliable, and rapidly deployable mobile energy support.
Scenario Requirements: Meeting Flexible Power Supply Needs at Construction Sites
Construction sites typically exhibit the following characteristics:
- Constantly changing power consumption locations;
- Significant startup surges from large equipment;
- Short-term temporary power supply cycles;
- High demands for equipment mobility and deployment efficiency.
The project must achieve:
- Rapid deployment and relocation;
- Mitigate surge loads on large construction equipment;
- Reduce operating pressure on diesel engines;
- Compliance with green construction requirements.
Compared to traditional diesel-powered solutions, construction projects require a mobile energy system that combines both flexibility and high efficiency.
System Solution: Mobile Energy Storage Enhances Construction Power Supply Efficiency
Based on the specific characteristics of construction sites, YUNT provides integrated mobile energy storage system solutions.
Project Configuration:
- 500 kW/500 kWh mobile energy storage system;
- 4 units of 125 kW grid-forming PCS modules;
- Diesel power generation system;
- EMS Energy Management Platform.
The system features a modular design that allows for flexible deployment based on the scale of the project, facilitating transportation and rapid relocation.
During operation, the EMS automatically optimizes energy dispatch based on changes in the load of construction equipment:
Normal construction phase:
- The diesel engine maintains efficient and stable operation;
- Energy storage systems handle load fluctuations;
- Reducing frequent load fluctuations on the diesel engine.
During large equipment startup:
- Energy storage rapidly releases power;
- Mitigates startup surges;
- Reduces the need for larger diesel generator capacity.
Leveraging mesh-type PCS and multi-unit coordinated control technology, the system supports the stable operation of multiple modules and can flexibly expand capacity to meet on-site power demands.
At the same time, the entire system features a mobile design, enabling rapid deployment across different construction sites and improving equipment utilization.
Project Value: Enhancing Energy Security for Construction
Through the mobile energy storage system, the project helps clients reduce diesel consumption and on-site noise, improve the stability of construction power supply, and meet green construction requirements.
Compared to traditional fixed power supply methods, the mobile energy system can be rapidly deployed and relocated according to project progress, improving equipment utilization efficiency and reducing overall energy costs.
This project fully demonstrates YUNT’s technical capabilities in mobile energy storage, diesel-storage coordination, and system integration for temporary power scenarios. It can be widely applied to municipal engineering, rail transit, infrastructure construction, and large-scale engineering projects, providing efficient and flexible energy solutions for overseas temporary power projects.
