Construction sites are usually located in remote areas. Since the mains electricity cannot reach them, the traditional power supply method mainly relies on diesel generators, which provide a direct energy path. For decades, it has been the first choice for construction sites, but this does not mean that it has no disadvantages.
Diesel generators have problems such as high fuel costs, frequent equipment maintenance, noise pollution and serious carbon emissions, which make it difficult to meet the requirements of modern green development and efficient operation. To meet these challenges, energy storage systems, as an innovative energy solution, can supplement or even completely replace diesel generators and become an ideal choice for power supply in construction sites and mining areas.
A construction site in Israel faced a similar problem. The daily load demand of the construction site is between 30-50kW, while the power of the diesel generators it is equipped with is 160-250kW, which is much higher than the actual load demand. This excess power causes the diesel generators to run at low loads for a long time. Not only is the fuel efficiency low and the fuel consumption high, which increases the construction cost, but it also affects the surrounding environment due to high noise pollution.
For this reason, the customer decided to choose a more economical and environmentally friendly power supply solution. The solution provided by SCU, which combines energy storage with diesel generators, is the best practice for solving these problems. By optimizing energy management, it significantly improves the power supply efficiency and environmental friendliness of the construction site.
Hybrid Generator Battery System Green Solution
According to the customer’s situation, SCU provided a 215kWh energy storage container, which was combined with the customer’s existing diesel generator to form a BESS-DG Off-grid Green Solution. The excess power of the diesel generator is used to charge the battery, which then supplies power to the load, thus reducing the use time of the diesel generator, improving economic benefits and reducing environmental pollution.
How does the hybrid generator battery system work?
The BRES energy storage system achieves seamless collaboration with the diesel generator, adopts intelligent control logic, and automatically adjusts the working mode according to the battery SOC (state of charge):
- Battery SOC is greater than 80%
The energy storage system operates in VF (Voltage and Frequency) mode.
At this time, the battery power is sufficient, and the energy storage system shuts down the diesel generator through the dry contact signal, independently supplies power to the site load, ensures that the diesel generator is completely shut down, and saves fuel.
- Battery SOC is less than 20%.
The energy storage system operates in PQ (Power and Reactive Power) mode.
The battery power is low, and the energy storage system starts the diesel generator through the dry contact signal and switches to PQ mode at the same time. The diesel generator gives priority to supplying power to the site load and uses the remaining power to charge the battery until the battery SOC returns to normal levels.
This intelligent collaborative work realizes efficient cooperation between the diesel generator and the energy storage system, reduces the generator operation time, and reduces fuel consumption and equipment loss.
SCU hybrid generator battery system advantages
For the special needs of industries such as construction and mining, SCU’s energy storage system can operate stably for a long time under extreme conditions such as dust and high temperature, while meeting the high-intensity demand for energy on construction sites and mining areas.
Through advanced battery management technology and intelligent energy distribution strategies, the SCU energy storage system can significantly reduce the operating time of diesel generators, reduce fuel consumption and equipment wear, and extend the service life of generators. In addition, the energy storage system can also significantly reduce carbon emissions and noise pollution, creating a more environmentally friendly working environment.
