Legrand's Keor FLEX wins data centre sustainability award
Tue, 19th May 2026 (Today)
Legrand's Keor FLEX modular uninterruptible power supply has won the Data Centre Sustainability Innovation of the Year award at the DCS Awards 2026, marking the company's second data centre sustainability award in recent weeks.
The latest recognition follows a separate win for Keor FLEX in the Best Reuse or Recycling of Products, Energy, or Data Centre Infrastructure category at the Data Centre World Awards 2026. Together, the two awards reflect growing recognition for products aimed at cutting energy use, reducing waste, and extending equipment life in data centre environments.
The DCS Awards are voted on by readers of publications in the Data Centre Solutions and Digitalisation World portfolio. The sustainability category recognises products intended to improve energy efficiency and environmental performance in data centres.
Keor FLEX is a modular UPS platform rather than a fixed monolithic system. That approach allows operators to replace or upgrade individual modules instead of an entire unit, reducing material use and supporting longer service life.
The system reaches up to 98.6% efficiency in double-conversion mode and more than 99% in ECO mode. It is also certified as 85% recyclable under IEC/TR 62635 and can work with several battery types, including lithium-ion, VRLA, and nickel-zinc batteries.
Keor FLEX can scale from 100 kW to 1.2 MW per frame and up to 4.8 MW in parallel. According to Legrand, the design delivers 1.2 MW within a footprint of 2.8 square metres.
The UPS uses silicon carbide technology and an internal busbar architecture that, according to the company, lowers thermal stress and reduces potential failure points. These features are intended to extend component life while helping operators manage electricity use and maintenance demands.
The system has also been positioned for data centres handling variable and intensive computing loads. Legrand said it supports the dynamic load profiles associated with artificial intelligence workloads and is ready for functions including peak shaving, load balancing, and fast frequency response.
Wider focus
The award comes as data centre operators face increasing pressure to improve energy performance while supporting rising demand from cloud services and AI infrastructure. As a result, operators and suppliers have placed greater emphasis on equipment efficiency, asset reuse, and designs that can be upgraded without full replacement.
For UPS vendors, this has become a key area of competition. Power protection systems are a core part of data centre infrastructure, and their efficiency can directly affect operating costs and site energy consumption.
Modular designs have gained attention because they allow facilities to add capacity in stages and carry out maintenance with less disruption. They can also limit overprovisioning, where operators install more capacity than they immediately need, increasing both capital spending and energy waste.
Executive view
Marc Marazzi, Vice President at Legrand Data Centre 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."
Legrand operates across electrical and digital building infrastructure markets, including data centres. Its data centre business provides grey space and white space products through brands including Minkels, Raritan, Server Technology, Starline, and USystems.
The broader group reported sales of €9.5 billion in 2025. Its latest award adds to evidence that sustainability claims around power and infrastructure equipment are becoming a more prominent part of purchasing decisions in the data centre sector.
Keor FLEX was recognised in a category focused on products that deliver measurable improvements in energy efficiency and sustainability within the data centre environment.
