Introduction KEMA Inc has been awarded by the Pacific Pow er Association (PPA) in Fiji to carry out a project called “Quantification of Energy Efficiency in the Utilities of the U.S. Affiliate States (Excluding US Virgin Islands)”. In this Electrical Data Handbook all the electrical characteristics of the powe r system high voltage equipment of American Samoan Power Authority (ASPA) in the main island of American Samoa is provided. All relevant data of the high and medium voltage assets, such as generation data, impedances of lines, cables, transformers, and other equipments if exists. KEMA has incorporated major data of components and equipment in power g eneration, transmission, distribution and metering. Data template is established to hold comprehensive equipment data, for example for transformers data collected power ratings, primary and secondary voltages, load and no load losses, tap changer data, BIL ratings, cooling class, applicable standards, weight, etc. 2. Data Content All data contents are identified based on the ETAP power system model and other information KEMA received. 2.1 Generators There are 17 generators in ASPA power stations . Generator data are provided in the table below. The MW de-rated value for the generator units are provided separately from the ETAP model.

There are two 750kVA transformers in Tafuna power station serving as step -up transformer to transfer power generated by the Caterpillar units from 480V to 13.2kV at the power station terminal bus. Station transformer data are provided in table below.
