In this paper, the customer satisfaction model of power supply industry is constructed based on the related thesis, and the model is validated by SAS 8.1-CALIS, for which data is collected from 800 customers of Jiangsu Power. Highlights of the findings include that (1) customer expectation can be cancelled from the model, because it's of no significance on customer perceived quality, perceived value and customer satisfaction, and (2) corporate image mainly produces an indirect effect on customer satisfaction and customer loyalty, nearly no direct effect, and (3) the average R2 of five endogenous latent variables in modified model is 0.69. In summary, the modified model is of validity and reliability. At last, suggestions are put forward for promoting customer satisfaction and customer loyalty in power supply industry.
