Abstract: Energy Performance Contracting(EPC)is a kind of energy-saving management mechanism that uses energy costs saved in the future to pay cost of energy-saving project. In guaranteed savings EPC model, energy-consuming clients take the responsibility for project financing, while energy service companies provide a complete set of service for the project and guarantee certain performance to their clients. If the project fails to meet the guaranteed value, the energy service company would pay compensation to the client, otherwise, the client would offer certain reward to the company. A contract parameters decision problem is a basic problem in the application of this model. This paper takes the decision problem of initial project investment, contract period and excess project performance reward in guaranteed savings EPC model as research objectives, establishes a decision-making game model between the client and the energy service company to analyze optimal contract decisions.The results of numerical experiments show that this method can not only benefit both the client enterprises and the energy service companies, but also effectively improve the project return-on-investment rate. And higher energy service companies’ technology level and the client enterprises’ initial energy-consuming level would bring higher energy-saving efficiency.
