Abstract: Electricity in an iron & steel factory mainly comes from two parts: one is selfgenerating electricity， and the other is outsourcing electricity.How to allocate reasonably the ratio between them is particularly important. Carrying out scientific and rational power production and analysis for production scheduling， reducing economic costs are very important work. In this paper， the standard coal equivalent coefficient was used to analyze power and the calculating formula was deduced. The data from the factory was used and showed that the outsourcing electricity of 295% is the most economic. The accuracy of the formula is verified.

Key words: electric power, selfgenerating electricity, outsourcing electricity, standard coal equivalent coefficient
