Not only in homes and office buildings but in factories, energy saving is an important management theme. It is well known that energy saving is closely related to productivity improvement in the factory. However, it is difficult to visualize and analyze the energy information in association with the production information because the energy information and the production information are collected independently in the factory. In this paper, in order to solve this problem, we propose a factory energy management system that works with production information. In the proposed system, the PLC (Programmable Logic Controller) equipped with the power measurement unit collects energy information in association with the production information. Based on the collected information, the energy management system provides the energy visualization and the energy analysis capabilities by specific energy consumption. In this study, by introducing the proposed system to a production line of breaker in the factory, we evaluated the effectiveness of the proposed method.
