Abstract: The Second West-to-east Gas Pipeline is the first large pipeline project importing oversea natural gas to China. It is also the embodiment of the strategy of energy resource diversification in China. In the future 30 years, China will import 30 billion m³ of natural gas from central Asia through the 2^nd West-to-east gas pipeline every year. China has set up the strategy of improving the structure of power generation energy resources and developing clean power. As clean energy, gas for power will not only improve power generation structure but also reduce emissions. However, the electricity market and the related industrial policies are still immature. This paper analyzes the main obstacles of developing gas power generation and makes a financial analysis on a typical gas plant in Guangdong. Based on the calculation results, this paper puts forward several suggestions from the perspective of electricity price, gas price, tax policy, dispatching mechanism and trade mode of natural gas for power generation. The research aims at providing decision support for the development of the 2^nd West-to-east gas for power generation and the implementation of the national energy strategies.
