In view of the expanding peak-valley gap in an urban gas supply system, this paper made a comparative analysis of all types of peak-shaving methods and proposed a strategy of adopting the way of LNG stations as peak-shaving and emergency reserves. The cost premium showed that LNG stations with storage tanks should be appropriate for big cities while small LNG gasification stations, the so-called LNG satellite stations, for the small and medium-sized cities. Due to the price difference between the purchased LNG and natural gas, the CNG price adjustment fund will be taken advantage of in the short run but the way of peak shaving gas price will be in the mid-long run. In a case study in Sichuan and Chongqing areas, this paper analyzes the impact of LNG storage stations on the regional economy. It was found that the proposed strategy of LNG storage stations is feasible, and especially in spring and winter times, gives a slim chance of survival for the fuel gas cutting industries in the past. In this way, not only is the substantial economy maintained steady, but the LNG industrial chain is fulfilled and The Regulation and Administration of Urban Gas will be implemented. In the end, this paper suggests that the government should play a dominant role in encouraging and stimulating the construction of LNG storage stations in the following aspects: to make a reasonable scheme and layout of the LNG industrial chain; to compulsively command those fuel gas companies in big cities to construct LNG storage stations; to formulate preferential and encouragement policies on the projects of LNG storage stations; to stipulate the standard reserves volume for the fuel gas companies in the city at all levels; and to study the proper time to put into force the gas price at peak-shaving times or gas price ladder for residents.
