A methodology for managing portfolios of energy saving projects at metallurgical enterprises is proposed. It forms a paradigm of predictive adaptation based on interconnected adaptive systems for planning, monitoring and managing changes and allows for forecasting energy consumption for complex technological processes and production, as well as modeling and evaluating the quality of the fuel and energy balance, in conditions of limited resources and risks, to form and select energy saving

A multi-level model of energy consumption of a metallurgical enterprise has been developed, which makes it possible to assess the effectiveness of energy-saving projects selected for implementation, objectively assess the share of each energy resource in the total flow, determine the energy intensity of a separate production, workshop, and the entire enterprise, and adjust the strategic direction in energy management. Using the model, it is possible to solve a number of tasks, including assessing the rationality and efficiency of the existing energy consumption structure at the enterprise, predicting the expected levels of energy consumption when changing the technology, product range and quality, and comparing various technologies and equipment in terms of energy efficiency, optimal management of energy flows taking into account changes in production conditions. The basic requirements for the organization of a planning and management system for a portfolio of energy saving projects at a metallurgical enterprise are formulated. The block diagram of a computer system for planning and managing a portfolio of energy saving projects at PJSC "Dneprospetsstal" is presented. The developed system of energy saving processes should be built into the system of enterprise processes, correspond to the strategic goals of the enterprise and the characteristics of the production process. The scheme of energy costs planning process implemented at the enterprise was considered.
