Potencial para eficiência energética em segmentos do Polo Industrial de Manaus/AM

Abstract

The potential for energy efficiency in the industrial sector is quite significant because it is the sector that consumes the most energy in Brazil and worldwide. In recent years, intensified advances in energy efficiency in energy-intensive industries within the global scenario. However, there is still significant potential for global efficiency, especially in emerging economies. In Brazil, the socio-economic development vector of the Amazon is the Industrial Pole of Manaus (PIM). To increase their competitiveness, manufacturers need to optimize their production processes, reducing energy costs and losses. Considering the relationship between efficiency and power quality in productivity and turnover of industries, it is necessary to know how energy is being consumed and the efficiency with which the various segments of the PIM. The objective of this study was to determine the energy efficiency indicators like the specific energy consumption, load factor and average cost of energy as well as the determination of power quality indicators, by analyzing the measured electrical parameters in the main consumer systems of three industries with large representation in the regional scenario. The methodology included field survey, implementation of energy characterization of questionnaires and electrical measurements. The results showed that the industries had indicators of efficiency, for the most part, better than the national average, however, it was found that most consumer industries systems presented disorders related to power quality such as low power factor and harmonic content. Thus, there is a potential for energy efficiency in industrial systems.
