This paper’s purpose is to provide a method for the risk evaluation of China’s petrochemical Energy Performance Contracting (EPC) projects. EPC which originated in the United States in the middle of 1970s developed rapidly over 40 years. In 1997, EPC was introduced into China as an advanced energy management mode. For nearly 20 years, EPC has been developing rapidly in China. However, in the petroleum and chemical industries of China the process of EPC is slow. Through literature analysis and questionnaire survey, the risk index system of China’s petrochemical EPC projects has been constructed. Based on this, an improved G1 weighting method and fuzzy comprehensive evaluation method are applied to evaluate the risk of the EPC project of the Ningxia Petrochemical Company.
