The iron and steel industry is a fundamental part of national economy, but it is also the large energy user. The accurate predictability of the energy consumption is beneficial to seize the energy development trends and reduce the energy waste. According to the historical data of integrate energy consumption per ton crude steel (IECPTCS) about our country, a novel prediction model of the IECPTCS is proposed by using Gene expression programming (GEP). Firstly, the IECPTCS is divided into equal time intervals. The functional expression is represented by some symbols. A parameter, which is stored as constant, is defined in the terminal set. Secondly, the prediction model is obtained by genetic operation, which contains selection operation, mutation operation, recombination operation, transposition operation, etc. Finally, the experimental results show that the average error between the predicted value and the real value is 0.649 via GEP, which is superior to other approaches. It also illustrates that the novel prediction model can forecast the development trends of the IECPTCS accurately.
