Cummins Power has launched the Centum series QSK78 high-power 50Hz generator sets, providing a high-density and low-carbon backup power solution for global AI data centers.

June 18, 2026, Daventry, UK – Cummins Power Generation, a global leader in power equipment manufacturing, has expanded its award-winning Centum high-horsepower generator portfolio by launching brand-new gensets powered by the QSK78 V18 engine platform for all 50Hz markets across Europe, the Middle East, Africa, Asia Pacific and Latin America. Targeting mission-critical sites including AI hyperscale data centers, top-tier hospitals, large wastewater treatment plants and mining facilities, the new product line delivers integrated emergency and prime power solutions featuring ultra-high power density, ultra-fast load response and sustainable low-carbon operation, to address surging power security demands driven by worldwide computing infrastructure expansion.

The newly unveiled QSK78 platform is a 78-liter V18 heavy-duty diesel engine, delivering maximum standby power up to 3500kVA and prime power of 3300kVA under standard 50Hz operating conditions. Scalable Tier 2 low NOₓ emission kits are available for two major operation modes: year-round continuous power supply for data centers, and millisecond-level emergency backup power during grid blackouts. Equipped with exclusive Centum integrated transmission and compact modular layout, the unit cuts overall footprint by nearly 18% compared with competitors at the same power rating, drastically reducing comprehensive capital expenditure on civil construction, sound attenuation enclosures and cable piping, making it ideal for land-scarce high-density computing campuses in urban core zones.

All gensets are factory fitted with Cummins proprietary PowerCommand®3400 intelligent control system, delivering industry-leading precision for voltage and frequency regulation, supporting multi-unit parallel connection, N+1 redundant networking and full-dimensional cloud remote monitoring. Under extreme shock conditions such as instant grid failure, sudden load spike of AI server clusters and synchronous startup of large cooling equipment, the unit can fully take on full load within 10 seconds, with transient voltage fluctuation far exceeding international G3 power supply standards for data centers, effectively eliminating catastrophic losses including computing hardware downtime, shutdown of precision medical equipment and suspension of industrial production lines. For overseas mining sites with high temperature, heavy dust and high altitude, factory optional upgrade packages including reinforced multi-stage air filtration, high-altitude power compensation software and cold-start preheating kits enable stable rated power output within a wide ambient temperature range from -40℃ to 50℃, adapting to global projects under harsh geographic conditions.

Nacho Gonzalez, Executive Director of Cummins Power Generation for EMEIA (Europe, Middle East, India and Africa), stated at the launch event that global digital infrastructure development is accelerating at unprecedented speed, and AI large model and cloud computing campuses impose three strict core requirements on backup power: reliability, rapid response and low carbon performance. The QSK78 50Hz genset represents a landmark upgrade of Cummins high-power product line, built on over a century of engineering expertise while unlocking diversified low-carbon fuel pathways. All units are fully compatible with HVO hydrotreated vegetable oil without engine modification, cutting over 30% of full-lifecycle carbon emissions and enabling overseas clients to comply with tightening global environmental regulations and achieve corporate carbon neutrality targets.

Apart from standard standalone units, Cummins also supplies containerized silent gensets and integrated diesel-storage hybrid microgrid solutions, deeply combining QSK78 gensets with BESS battery energy storage systems and intelligent grid-tied control cabinets to realize smart coordination among municipal grid, diesel power and energy storage. The storage system charges during off-peak electricity price periods and supplies priority power at peak hours, while the diesel unit only serves as ultimate backup for severe power outages, significantly reducing long-term fuel consumption and maintenance costs. The complete microgrid package supports full pre-shipment third-party inspection and certification, with official test reports issued by accredited institutes such as SGS, fully matching foreign trade procedures including L/C settlement and customs clearance filing for overseas buyers.

For global after-sales support, Cummins operates an authorized service network covering more than 190 countries with centralized global genuine spare parts allocation. Overseas projects enjoy 48-hour on-site engineer service and 7×24 remote technical support. For export gensets ranging from 600kW to 3500kW, Cummins can assist clients with full product certification, certificate of origin, third-party inspection and customs declaration documentation, streamlining cross-border trade procedures for bulk engineering orders in the Middle East, Africa and Southeast Asia.

Paulette Carter, Executive Director of Cummins Power Generation Global Data Center Business, added that the power gap brought by global AI computing expansion has elevated "power resilience" from an optional extra to an essential requirement. The QSK78 series integrates three core strengths: compact footprint for high-density layout, ultra-fast transient load response and sustainable low-carbon performance, suitable for both newly built hyperscale data centers and capacity expansion renovation of legacy facilities. Global order inquiries for this product line are now fully open; the technical team can customize unit configuration, noise reduction solutions and automatic control systems according to clients’ site dimensions, load characteristics, local emission standards and fuel supply conditions. In the future, Cummins will continuously boost R&D investment on high-power natural gas gensets and hydrogen-fueled power equipment, enriching the multi-energy product portfolio covering diesel, natural gas, energy storage and hydrogen power, to deliver integrated full-cycle reliable backup energy solutions for global critical infrastructure.
