Study on critical success factors of the energy performance contracting program in petrochemical industry under the dual carbon background

To realize the goal of Dual Carbon, energy emission reduction are urgent and important. The petrochemical industry is one of China's most energy-consuming industries, so its energy-saving potential is huge. The current petrochemical industry energy performance contracting program research is limited, and there are many problems and obstacles to development, research on critical success factors of energy performance contracting program in petrochemical industry is conducive to improving the development of energy performance contracting in petrochemical industry. This study identifies 31 indicators of critical success factors for energy performance contracting program in the petrochemical industry from three aspects: external factors, internal factors, and the project's factors. The research method combining Improved Hierarchical Analysis (G1), DEMATEL and Interpretative Structural Modeling (ISM) is applied to analyze the comprehensive impact degree, causality, and hierarchical relationship of the critical success factors of energy performance contracting program in the petrochemical industry, and the results show that the degree of local government support (I2), the energy-saving technology quality level (E6), feasibility of the technical program (P3), project energy efficiency (P6), the completeness of contract text (P9), and energy savings (P11) have a large degree of comprehensive impact, and there are 22 cause factors and 9 effect factors among the 31 critical success factors, and the ISM hierarchical relationship can be divided into 8 layers, which can clearly reflect the causality, hierarchical relationship, influence mechanism and path between factors in the petrochemical industry's energy performance contracting program, which has certain reference values and theoretical guidance for guiding the success of energy performance contracting program in the future.
