Low-emission power solution for wastewater project in the Netherlands
How a Stage V generator combined with ESS guaranteed optimal efficiency
A company in the construction industry was tasked with replacing an existing asbestos cement (AC) sewer line in a protected natural reserve in the Netherlands. Traditional diesel generators did not align with the project's green objectives. Therefore, Atlas Copco Rental supplied a hybrid system significantly reducing emissions and fuel consumption while maintaining efficient power delivery.
As a leader in sustainable underground and above-ground infrastructure, the company undertook the replacement of an AC sewer line with a new wastewater pipeline. Located in the floodplains of the Meuse river, the project demanded an emission-reducing approach due to its environmentally sensitive setting.
The work involved removing a 640-meter AC pipe from the dike's core zone and installing a 660-meter HDPE wastewater pipe closer to the Meuse – a process demanding substantial electricity for well pumps, cranes, a welding container, and other equipment. Conventional diesel generators were not suitable due to their high emissions, as indicated by national AERIUS measurements.
Hybrid energy bridging power and sustainability
Atlas Copco Rental therefore supplied a hybrid energy solution consisting of a QAS+ 200 generator paired with a ZBC 250-575 energy storage system (ESS). This Stage V generator was able to continuously operate at its optimal load of 77%, efficiently providing power to charge the ESS while directly supplying electricity to essential equipment.
Once the ESS was fully charged, it took over the power supply, allowing the generator to shut down 85% of the time. This significantly reduced overall emissions and fuel consumption, making the operation more environmentally friendly and cost-effective.
Energy storage system: the key to optimal generator operation
Why is an Energy Storage System (ESS) crucial for generator efficiency? Without an ESS, generators struggle with variable demand, often operating at less-than-optimal loads during low demand periods. This inefficiency leads to increased fuel consumption, higher emissions, and greater wear and tear, resulting in higher maintenance costs and a shorter lifespan. Moreover, any excess power generated is wasted as it cannot be stored for future use.
An ESS addresses these problems by storing excess power when demand is low and releasing it when demand is high, ensuring the generator operates consistently at its optimal load. This reduces fuel consumption and emissions, lowers operational costs, and extends the generator's lifespan, making it a more sustainable and cost-effective solution.
Sustainable power saving the day
Atlas Copco Rental's hybrid energy solution provided the company with a sustainable and efficient power solution for its critical wastewater project. By optimizing generator performance, the solution seamlessly met the project's environmental requirements while effectively reducing emissions and fuel consumption.
