The study considers the use of through consumption coefficients for the simplified calculation of energy performance indicators of metallurgical products in multi-stage production systems. It is shown that the conventional direct approach does not adequately account for internal relationships between technological stages, material flows, and secondary energy resources, which limits its applicability in predictive and comparative calculations. A simplified method is proposed in which through consumption coefficients are used as a generalized calculation basis for determining integral energy indicators of products without constructing a fully detailed model for each stage. The approach preserves high accuracy compared to the full calculation scheme while significantly simplifying the assessment of the effects of changes in production structure, product mix, and technological parameters. It is further demonstrated that the obtained energy indicators can be used for rapid calculation of related indicators associated with energy consumption, including fuel-equivalent values, primary energy equivalents, and carbon intensity, based on unified conversion factors. The proposed method can be applied in production planning, technical modernization of enterprises, and evaluation of the effectiveness of energy- and resource-saving measures.
