Abstract: Energy management for manufacturing animal feed requires efficiency in the electric motors that actuate electro mechanisms consisting in chain conveyors (3548 kWh/day), elevators of buckets (2626 kWh/day), types axis non-end screw (298 kWh/day) and conveyor bands (434 kWh/day); all with different types of mechanical transmissions mainly reducers, chains and straps that as major consumers of electric energy represent the greatest potential savings. On the other hand, energy performance indicators are needed for assessing the production of feed and implementing an energy management system. In this paper a methodology is applied to determine the operating efficiencies of the electrical motors to the current load factors and adjusted to the actual operating conditions. The case study is a balanced animal feed manufacturing plant. The energy base line of the processes of higher energy consumption was obtained as well as energy performance indicators of 10 kWh/t for the same productive levels (500 t/day), representing a reduction of 364 000 kWh/year and, consequently, 15% of the entry recorded of energy costs. This result is equivalent to generation costs at 120 t of oil/year, which means a saving of 6000 USD/year and 140.14 t of CO2 equivalent that is no longer emitted.
