Nessum Alliance has announced the multi-expansion of Nessum technology in commercial HVAC and smart grid applications with deployments conducted by Alliance members of Daikin Industries Ltd and Power Plus Communications AG (PPC). The alliance also exhibited cumulative worldwide shipments of LSI devices that are incorporated and have surpassed six million units, as per Panasonic Holdings Corporation, the technology licensor, labelling its maturity and market adoption.
As energy management, digitalization, and sustainable infrastructure accelerate worldwide, organizations need communications networks that combine reliability and flexibility. By enabling high-speed IP communications over existing wiring, Nessum is expanding its role across energy-management applications.
Deployments by Daikin and PPC demonstrate how IEEE 1901*3-based Nessum technology delivers value in real-world infrastructure environments, connecting systems, devices, and operational data across critical sectors.
In the HVAC sector, Daikin is utilizing Nessum as part of its D4-NET architecture for next-generation air conditioning networks. As buildings rely more on operational and sensing data to improve efficiency, comfort, and performance, reliable communications infrastructure is becoming critical. Daikin has positioned Nessum as key to the evolution and global deployment of HVAC networks.
In Europe, PPC is advancing smart metering and grid modernization initiatives requiring reliable, long-distance communications over existing infrastructure. Its activities show how Nessum can meet smart-grid requirements while helping utilities improve visibility, efficiency, and network management.
The Alliance also noted that, according to Panasonic Holdings Corporation, cumulative shipments of LSI devices incorporating Nessum IP have exceeded six million units worldwide. This milestone demonstrates Nessum’s maturity in large-scale deployments.
Originally developed for high-speed communications over existing wiring, Nessum has evolved into a versatile platform supporting HVAC, smart grids, building automation, industrial facilities, and other IoT applications. It enables organizations to modernize infrastructure while reducing deployment complexity and cost.
“As energy management becomes increasingly important across industries, demand for reliable, scalable connectivity continues to grow. Nessum’s growing adoption in HVAC and smart grid applications shows its ability to address real-world challenges and support a more efficient, sustainable future.”-
Michimasa Aramaki, Chair of Nessum Alliance
Nessum Alliance will continue working with industry leaders to promote interoperability, ecosystem growth, and adoption of IEEE 1901-based communications technologies for connected energy-management infrastructure.
