The present state of energetic management is facing several issues, including force to lower production power consumption, to increase efficiency of the production and among others to eliminate financial penalties for energy spikes drawn from the power grid. Especially financial penalties can be eliminated keeping power consumption of the production line in specific boundaries and has immediate financial effect. One solution, how to keep power consumption right, is by the digital energetic model of the production line. This paper originate from real operation measurement and describe methods used in digital model.Keywords: model, energy consumption, penalty fees, power grid.
