Therefore, Enterprise Resource Planning Systems (ERP-Systems) are used to support the production planning process. These systems strongly focus on dates, inventory and capacities. Due to the German exit from nuclear and fossil-fuel energy, a new variable gains in importance throughout all areas of production: Energy. As a reaction, energy and power demands of the manufacturing systems are more and more monitored within the factories in order to enable energy-efficient operations. The energy supply of a factory is currently not recognized in the planning process. This paper provides a systematic approach to integrate energy supply information to the production planning process on the basis of ERP-Systems. This will be discussed by combining the idea of energy-efficiency and energy-flexibility as well as the alternatives of a factory's internal and external energy supply.enjournal article
