[Abstract]:On March 15, 2015, the CPC Central Committee and the State Council issued some opinions on further deepening the reform of the electric power system (Zhongfa [2015] No. 9), which clearly proposed the active development of distributed energy and the opening up of the user-side distributed energy market in an all-round way. Natural gas distributed energy is a comprehensive utilization system of natural gas built on the user side or user load center. It is based on the cogeneration technology of heat, electricity and cooling, and runs with the distribution network and the natural gas network. It also provides power, steam, hot water, air conditioning and other energy services to users or specific users in a given area. Natural gas distributed energy is a system based on the maximization of resource and environmental benefit and the best matching mode and capacity between supply and demand. It has the characteristics of high efficiency, safety, low carbon, green, intensive, fine and intelligent in modern energy system. In this paper, the financial feasibility of M natural gas distributed energy project in Sichuan Province is studied, which provides an important basis for the construction of the project and has important theoretical and engineering guiding significance. This paper is divided into six chapters. The first chapter mainly studies the background of this paper, the investment project overview, the content framework and the main significance; the second chapter mainly studies the natural gas distributed energy investment environment, This paper analyzes the distributed energy market of natural gas in Sichuan Province by using Porter's five-force analysis method, the third chapter mainly studies the technical scheme of M natural gas distributed energy project, the fourth chapter mainly studies the financial evaluation of the project. The fifth chapter mainly studies the risk evaluation and preventive measures of the project, the sixth chapter is the conclusion of this paper, and puts forward some suggestions for the healthy and orderly development of the industry from the perspective of sustainable development. Based on the analysis of energy use data of M natural gas distributed energy project, this project plans to build 2 sets of distributed energy units with a total installed capacity of 109 MW for 60 MW grade gas-steam combined cycle. After the project is completed and put into production, For the whole year, the direct power supply is 145.2 million kilowatt-hours, the Internet power is 366.7868 million kilowatt-hours, the steam volume is 227700 tons, and the cooling capacity is 1.526 million gigajoules. When the price of natural gas is 1.77 yuan / cubic meter, the electricity price is 613 yuan / megawatt, the direct supply price is 560 yuan / megawatt, the cold price is 73.45 yuan / gigai, and the steam price is 220 yuan / ton. The internal rate of return on project investment is 8.39 yuan, the net present value of project investment is 25.9509 million yuan (benchmark rate of return is 8%), the internal rate of return on project capital is 12.5 yuan, and the net present value of project capital is 64.4084 million yuan (benchmark rate of return is 10%), meeting the investment standards of relevant enterprises, It is proved that the project has the feasibility of investment. The sensitivity analysis of natural gas price, electricity price, heating (cold) price, total investment and so on, shows that the project has strong ability to resist risks.
