As an international best practice, docked ships are required to switch off their generators and use utility power for their activities once in the harbour port as one way to reduce emissions. This paper seeks to analysis the 132kV Kenya power supply from Juja to Mombasa in an effort to assess its capacity and stability with various categories of 22 docked ships connected at Port of Mombasa. The Coast Region power distribution network will be modelled using PSAT. Specific critical buses will be studied with an aim of proposing possible mitigations that can be taken if they are likely to experience voltage drops/ collapse. The loading limits on each of the buses will be determined using continuation power flow. The results will be used to assess the capability  of connecting existing ships loads and as a planning tool for future proposed port expansion for cruise and larger container vessels at berth No. 1 and second container terminal phase 2 respectively.
Keywords: On-  shore power, Emissions, PSAT, Continuation power flow.
