Abstract: This Dissertation identifies the Demand Side Management (DSM) implementation opportunities and the resultant energy and cost saving potentials in a Container Terminal, through continuously monitoring the electrical load profile by digital measurement meters on a round-the-clock basis for a 12-month period. Electrical parameters such as voltages, currents, power factors and total harmonic current content, kVA Demand and kWh Energy Consumption for each of the major electrical load system in a Container Terminal are measured. All field data are captured and sent via data signaling cable to a computer, which log and save the measured data as the database. The load profiles and energy consumption characteristics for each of the major electrical load system in a container terminal are established for DSM opportunity identification. The kVA Demand and kWh Energy Consumption reduction measures with the potential electricity cost savings are extensively scrutinized and discussed. The container terminal operations are complex and dynamic processes. The type of container (export, import or transshipment cargoes), the weight of container (empty or laden), the processing dwell time, the container vessel port time, terminal handling efficiency in terms of resources deployment and container handling rate intrinsic with the container terminal operations make the load profile and energy consumption of the container terminal not just simply throughput dependent. A regression analysis has been used to co-relate the energy consumptions to the terminal throughputs, the mean air temperatures and the respective operation dependent factors of the electrical load systems under study, aiming to formulate and understand their relationship with regard to the use of electrical power in a container terminal. The results obtained provide a basis in understanding the load profile and energy performance of a container terminal that might enable the Terminal Operator, Utility, Government and engineers in setting DSM strategies and implementing demand and energy saving measures for the container terminal industry.
