Abstract: The objectives of this research were to study the knowledge management process (KMP) and to validate the consistency of the KMP model in electricity generation process, by using a confirmatory factor analysis. Population in this study was the supervisors related to the operation and maintenance of power plants, with a total population of 1,555 persons. 635 sampling were selected by stratified random sampling. Instrument used in this study was questionnaire to evaluate the KMP level in the electricity generation process. All questions have the confidence to equal 0.9707; therefore, it can be used. Exploratory factor analysis using SPSS software, to explore a number of factors that are the KMP. The confirmatory factor analysis using AMOS. The results of this study shows that the KMP model in electricity generation process, consist of six constructs include knowledge identification, knowledge acquisition, knowledge creation, knowledge sharing, knowledge storage, knowledge transfer and utilization, all constructs model is valid and well fitted to empirical data, indicating that the constructs of knowledge management in electricity generation process is appropriate to fit the empirical data as well.
