The factors influencing the energy efficiency level of a metallurgical enterprise have been determined. They are necessary to develop a theoretical and methodological approach for managing the energy consumption mechanism of a metallurgical enterprise in the new business environment and calculating energy efficiency indicators. A system model for the formation of projects portfolio in accordance with the energy efficiency strategy of a metallurgical enterprise is presented, using methods of set theory, systemic and multi-criteria analysis, agent-based simulation modeling, and methods for analyzing risks and uncertainties.

This paper considers the features of managing the energy saving and energy efficiency projects and programs at the metallurgical enterprises. It suggests a multilevel model for management of the energy saving process at the enterprise. This model allows sequentially analyzing the project in order to recognize opportunities of implementation the tasks, agreeing upon the project realization plans and the plans of the enterprise on the different levels of planning, and choosing the most perspective projects that suit the development strategy.
