Reefers can be stacked like regular containers at a dedicated area where electric plugs are available. The above photo displays the reefer stacking area at the Maher Terminal at the Port of New York and New Jersey. Power outlets (poles) are provided for each row and up to 4 stacked reefers can be plugged. The small platform in the front is designed to be elevated by a fork lift so that a yard worker can plug or unplug a stacked reefer as well as monitor the temperature readings.
