- Abstract
As a key state engineering project, the interconnection pipeline project plays an important role in strengthening resource exchange and effectively alleviating the gas shortage in North China. At present, however, there is no feasible economic evaluation method for such an engineering project. In this paper, the functions of gas pipeline interconnection were divided into three parts, i.e., gas supply, gas transfer, and gas security, according to the characteristics of the interconnection construction project. Then, corresponding to these three functions, three economic evaluation models of the interconnection engineering project were established based on the economic evaluation method of long-distance pipeline projects, the economic benefit evaluation method of UGS peak shaving and gas transmission and the quantitative evaluation method of safety economic benefit. Finally, these models were applied to the interconnection project of the Fujian-Guangdong branch and trunk pipelines contracted by PetroChina for the economic benefit evaluation. And the following evaluation results were obtained. First, the financial internal rate of return of this gas interconnection project is 10.57%, 11.83% and 1.67% corresponding to the function of gas supply, gas transfer and gas security, respectively. Second, the financial internal rate of return of the whole project is 6.49%, which is higher than the reference rate of return of 6%, indicating that on the whole, this project is financially feasible. In conclusion, when the economic benefit of the natural gas interconnection pipeline project is analyzed, the economic benefit of gas supply, gas transfer and gas security shall be firstly evaluated respectively and then integrated to evaluate the overall economic benefit of the whole engineering.
