(i) Shore power is readily available for the vessel from utilities or port authorities; and
(ii) Shore based power supply systems are capable of providing all needed electricity required for vessel operations; and
(iii) The vessel is equipped to connect to shore-based power and such systems are compatible with the available shore power.
