Abstract: This study, investigates the energy efficiency potential of a cement production process based on the operational control approach, which has been developed. In this context, indicators that concern consumption of specific energy users were defined and limit values were determined. Accordingly, energy efficiency potential was found to be 3.5% depending on the control of 122 operational parameters. When the consumption loads of the enterprise are taken into account, the annual savings potential was found to be 4.5 GWh/year of heat energy and 39 GWh/year of electricity. These processes indicated a total of 10,334.99 tons of CO₂ per year. At the end of the study, the contribution of the developed approach to the energy management processes was evaluated. In this respect, in cement production, mill inlet temperatures, secondary temperature, and main drive power emerge as the main operational indicators for energy efficiency for raw mills, rotary kiln, and cement mills, respectively.

Keywords: operational control; energy management; efficiency; cost; sustainability.
