Optimize Your Power Solutions

When addressing temporary power requirements, relying solely on a single generator is not always the most effective or resource-efficient approach. In many operational scenarios, power demands fluctuate significantly depending on application conditions, time of day, or project phase. If your application exhibits variable load profiles, or if certain gensets within your fleet periodically require additional capacity to meet peak demands, then the adoption of a Modular Power Plant—achieved through the parallel operation of multiple generators—offers a significantly more efficient and adaptable solution compared to the use of a single large unit.

To support these operational needs, Atlas Copco has developed an advanced Power Management System (PMS) designed to optimize generator fleet performance. This system actively monitors load demand and automatically adjusts the number of generators operating in parallel by starting or stopping units as required. Through this dynamic control process, each generator consistently operates within its optimal load range, maximizing fuel efficiency while minimizing unnecessary fuel consumption. The PMS ensures that power delivery aligns precisely with real-time demand, contributing to enhanced system reliability and operational economy.

Additionally, the PMS mitigates the adverse effects associated with running generators under low load conditions. Prolonged operation at low load levels can cause detrimental issues such as incomplete combustion, carbon buildup, and increased mechanical wear, all of which can significantly reduce engine performance and overall service life. By maintaining generators within their ideal load range, the PMS not only protects equipment integrity but also extends the operational lifespan of the generators, reduces maintenance frequency, and contributes to lower total cost of ownership.

Just one example:

The deployment of a 1MVA generator as a prime power source, taking the load demand patterns of a typical industrial application as a guide, could mean up to 1677 liters of fuel consumed each day. That compares with approximately 1558 liters of fuel if three QAS 325 in the PMS were doing the same job. In this case, even considering the Ad-Blue cost, an estimated annual saving of more than €30.000 makes for a compelling case, not to mention 85 tons of CO2 saved over the course of a year.

A Hybrid Energy Solution That Boosts Performance

As sustainability becomes an increasingly critical focus across machine-driven industries, the tightening of regulatory standards surrounding noise pollution and carbon emissions has accelerated the demand for more environmentally responsible technologies. There is a growing need for solutions that can deliver reliable and consistent power while operating quietly and minimizing environmental impact. Energy Storage Systems (ESS) represent a pivotal advancement in this field, offering silent, efficient energy management. Atlas Copco is at the forefront of this transition, spearheading innovations that promote sustainable operations without compromising on performance.

Energy Storage Systems are particularly well-suited for deployment in noise-sensitive environments where traditional generator operation may not be feasible or desirable. Applications such as public events, urban construction sites, telecommunications infrastructure, and rental power solutions greatly benefit from ESS integration. Furthermore, when deployed in parallel, large-scale ESS units can function as the central control unit—the “brain”—of a microgrid, intelligently managing energy flow and distribution. By incorporating long-life, low-maintenance, and high-energy-density lithium-ion batteries, ESS solutions operating in hybrid mode alongside generators significantly enhance overall system efficiency, particularly when accommodating variable loads and peak demand scenarios.

The integration of an Energy Storage System with a generator operating in hybrid mode offers multiple operational advantages. It enables the use of smaller, more compact generators, effectively reducing the total solution footprint and associated hardware costs. This approach not only extends the operational life of the generator by mitigating the wear associated with low-load running conditions but also improves fuel economy and overall system performance. Ultimately, the hybridization of power solutions with ESS technology advances the sustainability of operations on-site, aligning with modern environmental standards and contributing to reduced carbon footprints across industries.
