Reported capacity is the rated size of the listed installations, not electricity being produced now. Source dates and coverage differ, so newer facilities may be absent and historical records may remain.
How electricity works in American Samoa
Island systemSmall isolated grid
Diesel with solar microgrids; Ta'ū runs almost entirely on solar.
GenerationLocal power station
TransmissionIsland grid
DistributionIsland utility
CustomersSet tariffs

Who controls the grid
The American Samoa Power Authority runs power and water.
No power exchange: the utility produces or buys electricity and sells it at set tariffs.

What does “Island system” mean?
A small grid that is not connected to a larger network. One utility typically runs generation and distribution, often relying on imported fuel, with solar and batteries increasingly added.
