In times of global environmental challenges and rising energy prices, it is important to keep track of energy comsuption in manufacturing. In addition, this enables calculation of the CO2 footprint of both the manufacturing process as well as the manufactured part or product. Such data is key for CO2 footprint reporting, which is currently being implemented as a part of corporate social and sustainability responsibility requirements around the world. 

umati demonstrates how energy measurements can be executed and monitored in a standardized way. Foundation is the OPC 40001 UA for Machinery Companion Specification series with its building block for Energy Management (OPC 40001-4). This building block enables standardized access to energy consumption information for machines and their components. It is based on the generic specification OPC 34100 – Energy Consumption Management, developed jointly by PI, ODVA, the OPC Foundation, and VDMA. The model provides a predefined set of typical and market-relevant energy data points, making it easier for users to retrieve and interpret consumption values across different machine types and vendors. 

At the umati booth at EMO Hannover 2025, energy monitoring of various devices is displayed and the data confluence of various data streams is layed out in both dasboard and graphical analysis. 

Various partners support this important feature: 

• umati partner Konzeptpark provides WiFi SmartPlugs that capture energy consumption directly and feed the data into the umati dashboard. 
• the partnering dutch consortium "Factory of the Future is Now" collects energy monitoring data from its joint show case in hall 15 and feeds it into the umati environment 
• research institute PTW of Technical University Darmstadt demonstrates how energy consumption monitoring can be turned to added value through data sharing via federated data spaces.
