Abstract
The energy service business carried out by energy service companies (ESCO) is a relatively young business model. It aims at the cost-effective delivery of energy-efficient technologies and services. An energy savings performance contract (ESPC) undertaken by an ESCO utilizes the future energy saving to repay the installation cost for energy efficiency equipment and/or systems. The contracting terms in an energy savings performance contract are critical due to complexities. In general, there are two energy performance contracts, namely shared savings contract and guaranteed savings contract, respectively. The latter is more commonly used. In this study, the distribution model of benefit is modified from guaranteed savings contract where a guaranteed saving ratio is considered as a fundamental factor. To provide a more comprehensive model of energy saving, the benefit from considering carbon trading is also taken into account. An optimization model that maximizes the utility user’s profit is constructed based on the net present value method. Contracting terms such as the contract period, the distribution ratio between ESCO and energy owner are selected as decision variables. Different scenarios are built in consideration of subsidy from the government, the investment percentage of ESCO, and the expected return on investment of ESCO, respectively. Different case studies of shared savings contract, guaranteed savings contract and modified guaranteed savings contract are analyzed. It is found that a modified guaranteed savings contract would increase effectively the utility user’s profit by reallocating energy savings proportion and minimizing the contract period.
