AB Rokiškio sūris is one of the largest manufacturer of the dairy products in Lithuania. In order to produce a high quality product, an energy-intensive cooling and refrigeration process is necessary.                                                                                               In pursuit to reduce electrical energy consumption in refrigeration systems it was decided to implement Digital Twin.  Data from smart-metering and Scada is collected and analyzed in the real time at one EA-SAS platform. Set points for Refrigeration compressors operation are calculated at EA-SAS Cooling and sent to refrigeration control system automatically without human interaction.                                                                                          Project allowed to reduce the refrigeration system electricity consumption, it lets us to monitor the compressor room operation remotely and to know the system’s COP in real time, thus allowing to make maintenance decisions.
