Energy Consumption Management

Industrial companies are faced with the challenge of taking appropriate steps to efficiently manage their own energy requirements. The introduction of an energy management system according to the ISO 50001 standard has proven to be a promising approach. It provides the organizational framework for deriving energy efficiency actions based on recorded energy data, implementing them, and monitoring their effects.
The specification defines an UA information model for energy management systems in industrial automation and process automation industries. The purpose is to save overall energy consumption and energy costs, as well as the fulfilment of regulatory standards like ISO 50001 and the protection of the climate.
The model is intended to be scalable from small stand-alone devices to complete machines to production cells or entire factories and plants.
The general approach to cut down overall energy consumption and energy costs is a step-by-step circular approach. Starting point is the analysis of today energy consumption. With awareness about energy consumption of sections, machines and devices in the production plant, in a next step potential energy savings are identified. After the definition of potential energy savings, the next step is the realization of the identified savings.
Existing OPC UA models for Energy Management (OPC 30141) together with other fieldbus energy profiles serve as the basis for this companion specification. Also, the universal energy information model out of the project results of the IGF research project 21329 N “Development of energy management interfaces for IoT technologies (IoT_EnRG)” was used here.
