Records by technology

Counts records, not generation share · coverage & dates

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 the Cook Islands

Island systemSmall isolated grid

Solar supplies the northern islands; Rarotonga mixes diesel and solar.

  1. GenerationLocal power station
  2. TransmissionIsland grid
  3. DistributionIsland utility
  4. CustomersSet tariffs

Who regulates

Electricity rules follow New Zealand, with local oversight by the territory’s government.

Who controls the grid

Te Aponga Uira runs the Rarotonga grid; island councils run outer-island grids.

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 “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.
