Benefit Evaluation Of PPP Mode Of M City Natural Gas Peaking Project

With the adjustment of China's energy structure and the promotion of energy saving and emission reduction,the demand for natural gas consumption is increasing.In order to meet the peak demand of daily gas use in cities,especially for heating in winter,various regions have launched peak shaving projects of urban natural gas.On the one hand,urban natural gas peak shaving project not only has economic benefits,but also has very high social benefits;on the other hand,its construction and operation need to invest a lot of funds.It is of practical significance to explore the PPP mode of cooperation between government and social capital in urban natural gas peak shaving project.Moreover,in order to avoid investment decision-making mistakes,it is necessary to carry out scientific economic benefit evaluation and value for money evaluation before developing construction projects.Taking M city natural gas peak shaving project as an example,based on the analysis of peak and trough of natural gas demand in M city,comparison of peak shaving schemes,analysis of natural gas peak shaving gas source and selection of LNG storage and transportation mode,this paper determines the peak shaving scheme of LNG in M city,as well as the main equipment and investment requirements for project construction and operation.By using the method of combining economic benefit evaluation and value for money evaluation,qualitative and quantitative analysis are carried out respectively,and the economic benefit of M city natural gas peak shaving project and the value for money of PPP mode are analyzed and demonstrated.According to the qualitative evaluation criterion of the project value for money under PPP mode,the comprehensive score of the project is 82.5 points,and the evaluation result is higher than 60 points.According to the quantitative evaluation criterion of the project value for money,the value for money index can reach 90.96%.From this,it can be seen that the project using PPP mode to operate is more advantageous than the traditional mode;through the economic benefit evaluation during the project operation,the calculation is made.The net present financial value of the project after tax is 80.8436 million yuan,the internal rate of return is 13.15%,and the payback period of investment is 7.7 years.It is found that the profitability and solvency of the project are strong;moreover,the project belongs to the scope of national policy encouragement,and its social benefits are higher than its economic benefits.This study can provide reference for investment evaluation of similar projects.
