CEMS (Complex EMS) is an energy efficiency management platform application that collects and manages energy consumption data generated from each factory in an industrial complex as an energy management system for industrial complexes.This application provides various services for energy management to each factory manager, and proposes energy-efficient industrial complex operation plans to industrial complex managers through integrated energy control at the industrial complex level.The Complex EMS (CEMS) application provides the following features:* Energy monitoring: Real-time monitoring of energy consumption, such as electricity, gas, and heat consumed by factories in industrial complexes, to identify energy consumption and costs.* Real-time alerts and notifications: Set power peak criteria and provide real-time alerts and notifications to administrators when peaks are approaching.* Electricity rate analysis: We analyze power peaks and usage patterns to determine the suitability of the current electricity rate plan and recommend the optimal electricity rate plan.* Electricity price comparison by industry: Provides a benchmark function and comparison of electricity price with the same industry in the industrial complex.* Facility smart prediction: Provides a function to predict the point of failure of the facility through motor status analysis.
