INTEGRICT Industrial CEMS (Complex Energy Management System) is a cloud-based smart energy platform that provides total energy management and energy services for factories in industrial complexes. Unlike the existing Factory Energy Management System (FEMS), CEMS not only analyzes energy consumption by plant, process, and facility of each plant but also performs energy management from the perspective of industrial complexes. Furthermore, it serves as an energy platform and provides various services such as energy trading, facility maintenance service, and RE100 consulting through the participation of third parties in the energy sector.
