Shore power can be used to effectively reduce air pollutant emission of vessels at ports when the vessels are docked at the berth. However, at present, due to investment income imbalance, enthusiasm for the construction of port and vessel enterprises and to utilize shore power is low, which causes that use proportion for shore power is low. Economy for shore power is one of the most important factors to affect the construction proportion and use of shore power. In the Paper, the influence of service charge, power price and maintenance cost of shore power on shore power economy were systematically analyzed, and investment and income of shore power were analyzed and compared. Economic indexes for payback period etc. were calculated and analyzed, and relation and influence for related factors of shore power economy were deeply analyzed. Finally, related suggestions for promoting shore power use of vessels are docked at berth were proposed from the perspective of economy.
