The total energy consumption in China will continually increase in the future

facing two major trends including improving electrification level and changing in resources and environment. By the year of 2050

the power generation industry in China will maintain fast developing status

transforming and upgrading from the conventional energy power generation to new energy power generation

under the influences of resources

environments and the society. By comparing the technical specifications

economic indicators and other factors of the conventional energy power generation forms with that of the new energy power generation forms

the competition trends among different power generation forms were analyzed. The definition of substitution and the overall substitution trend between the conventional energy power generation and the new energy power generation were discussed. Taking coal-fired power generation as the example

the substitution potentials of the new energy power generation forms in the substitution range and the substitution time in different scenarios were discussed. The development strategies of technology research and industry application in power generation field under the substitution trend were put forward

which can provide references for development direction of power generation industry in China during the 13 th Five-Year Plan period and further future.
