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 Samoa

Who regulates

Who controls the grid

State-owned Electric Power Corporation runs generation and the grid.

Markets & power exchanges

No power exchange: the utility produces or buys electricity and sells it at set tariffs.

Regional grid

Not part of a larger synchronous grid or regional power pool.

What does “Vertically integrated utility” mean?

A single, usually state-owned utility generates, transmits and distributes electricity. Prices are set or approved by the government or a regulator rather than by a market.
