Refrigerated container yard usually uses standalone genset for each container. This not only occupies yard space, but also wastes lots of diesel due to the low working efficiency at low load level. SSME can save 30% fuel since it will switch on and off the gensets automatically according to the actual load. Also the reliability and stability of the electricity can be maintained even in the case of machine breakdown or routine maintenance. This is very important for the refrigerated container industry to ensure the quality of their goods will not be deteriorated.
