How to allocate energy-saving benefit for guaranteed savings EPC projects? A case of China

From the perspective of stakeholders, this paper uses Shapley value method to get the initial allocation solution to energy-saving benefit of guaranteed savings energy performance contracting (EPC) project, and uses AHP to determine the risk evaluation indicators and the weight of stakeholders. The fuzzy comprehensive evaluation method is used to determine the risk coefficients of stakeholders and normalize them. The initial allocation of energy-saving benefit is corrected by using the normalized risk coefficients to get the final allocation solution to the energy-saving benefit. The study shows that (1) It is reasonable to use the Shapley value method for the allocation of energy-saving benefit of stakeholders in guaranteed savings EPC projects; (2) In the process of forming a cooperative alliance among stakeholders of guaranteed savings EPC projects, all parties have synergistic risks; (3) The level of energy-saving benefits of the cooperative alliance has been improved. (4) The allocation of energy-saving benefit based on risk coefficient is more in line with the actual situation. The research results can provide a more realistic allocation solution to energy-saving benefits of such projects, and contribute to the smooth implementation of guaranteed savings EPC projects that occupy the mainstream position in China’s energy-saving service industry.
