Legrand’s Keor FLEX Modular UPS recognised for Sustainable Data Centre Innovation

The latest recognition follows Keor FLEX’s recent success at the Data Centre World Awards 2026, where it won the “Best Reuse or Recycling of Products, Energy, or Data Centre Infrastructure” category. Together, the awards reinforce Legrand’s position at the forefront of sustainable critical power innovation for next-generation data centres.

Now in its 16th year, the DCS Awards recognise innovation, sustainability, and operational excellence across the global data centre industry, with winners voted for by the readership of the Data Centre Solutions and Digitalisation World stable of publications. The 2026 awards placed a strong focus on ESG initiatives and technologies that deliver measurable environmental impact. The “Data Centre Sustainability Innovation of the Year” category recognises products that provide significant improvements in energy efficiency and sustainability within the data centre environment.

Designed specifically for modern data centres, Keor FLEX combines industry-leading energy efficiency, true modular scalability, and lifecycle-driven engineering to reduce operational energy consumption, minimise waste, and extend infrastructure lifespan.

Unlike traditional monolithic UPS systems, Keor FLEX has been engineered as a long-life, upgradeable platform that supports circular economy principles through modular reuse and reduced material consumption.

Key sustainability and performance benefits include:

• Up to 98.6% efficiency in double-conversion mode and over 99% efficiency in ECO mode 

• True hot-swappable modular architecture for zero-downtime maintenance and targeted module replacement 

• Scalable from 100 kW to 1.2 MW per frame, and up to 4.8 MW in parallel 

• Compact design delivering 1.2 MW in just 2.8 m² 

• 85% certified recyclability in accordance with IEC/TR 62635

• Support for multiple battery technologies, including Li-ion, VRLA, and Nickel-Zinc, enabling battery reuse during upgrades 

By integrating advanced Silicon Carbide (SiC) technology and an innovative internal busbar architecture, Keor FLEX reduces thermal stress, minimises failure points, and extends component lifespan — helping operators lower both operational costs and environmental impact.

Keor FLEX is also engineered to support the dynamic load profiles of AI workloads and is smart-grid ready, enabling peak shaving, load balancing, and Fast Frequency Response (FFR) to support grid resilience and renewable energy integration.

Marc Marazzi, Vice President at Legrand Data Center Solutions Europe, said:

“Winning the DCS Award for Data Centre Sustainability Innovation of the Year is a fantastic achievement and further validation of our vision for the future of critical power infrastructure.

Following our recent Data Centre World Award win for reuse and recycling innovation, this recognition demonstrates how Keor FLEX is redefining what sustainability means in the UPS market.

Data centre operators should not have to choose between performance, resilience, and sustainability. Keor FLEX was engineered to deliver all three — helping customers reduce energy consumption, extend asset life, minimise waste, and support the growing demands of AI-driven environments.”

The DCS Awards are among the data centre industry’s most respected accolades, celebrating innovation, sustainability, and operational excellence across the sector.
