The demand for electrical energy has increased significantly in recent years, this
significant growth brings with it several concerns regarding the service capacity of energy parks
in Brazil and around the world. Much is said about investing more and more in the infrastructure
of the energy generation chain, building more hydroelectric plants, wind farms and solar energy
parks, which are renewable energy generation options, as well as thermoelectric plants, as an
option for generating non-electrical energy. sustainable, which tells us today, although it is an
economically attractive option in terms of investment, it should be avoided, as the burning of
fossil fuels harms the environment. However, when the analysis is expanded, it is possible to
see that in addition to investments in infrastructure, actions need to be taken so that the sectors
with the highest energy consumption, such as industry, increase their investments in controlling
and improving the performance of their processes, in order to work towards the best energy
efficiency rates. This work proposes an energy efficiency monitoring model for an industrial
refrigeration system, using a specific energy consumption indicator, so that it is possible to
monitor the system's performance and implement improvements aimed at reducing the factory's
electrical energy consumption
