The invention provides a public service platform for industrial energy management. The public service platform comprises an application layer, a data center and a communication layer. The application layer mainly comprises parts of energy consumption online monitoring, economic operation analysis, electronic energy-saving supervision and enterprise service. The data center comprises a data storage module and a data analysis module. The communication layer is a data collection and data unification and normalization processing part. The system is based on enterprise CIM, and a unified data model is established via unified and normalized processing of enterprise information and energy consumption information, and a double engine mass big data management platform; according to the system provided by the invention, data sent by monitoring apparatuses of existing industrial enterprises can be encoded uniformly and a unified model parameter service is provided; and a standard real-time data service is provided for online monitoring of energy consumption and an energy-saving diagnostic decision, thereby solving the problems that existing enterprise energy consumption online monitoring systems are imperfect, the overall energy consumption trends and economic operating situations of the industrial enterprises cannot be comprehensively and timely grasped by government agencies, and the like.
