Currently energy supply of industries primarily designed for the use of individual supply technologies. Therefore often industries can only react to a limited extend to fluctuating, process-related demand and volatile availability of both, thermal and electrical energy supply. Especially the integration of renewable and efficient but also of conventional technologies, and the development towards hybrid supply systems in industry, makes best possible support for industrial companies in the optimization of the operation and the design of these plants necessary. The DigitalEnergyTwin lead project is meeting this challenge with, among others, the well-known Austrian printed circuit board manufacturer AT&S.

Project Goal

The goal of DigitalEnergyTwin is to support the industry with a method and a software tool to optimize the operation and design of industrial energy supply systems. Models for selected energy-relevant processes and renewable technologies are developed, validated and simplified, serving as a basis for the digital twin. The core of the project is the development of an optimization approach based on standardized examples as well as real applications in the manufacturing industry (printed circuit board manufacturing). For the first time, a solution for the tension between volatile renewable energy supply and its efficient use for fluctuating energy demand at process level in industry will be developed. The chosen method allows to be used by future energy managers in the context of virtual (and extended) reality. Due to the modularity and standardized development a maximum impact is achieved and transfer in other industrial sectors is guaranteed. Thus, the industry can be supported to reduce costs and investment risks of renewable energy systems and thus significantly increase their share. The Research Centre Energy is working in particular on detailed energy system modells for selected processes (energy relevant) and renewable energy supply technologies.

The project duration starts on 01.11.2019 and ends on 31.10.2023.


This project is funded by the Climate and Energy Fund and is carried out within the framework of the "Energy Research (e!MISSION)" program.
