Although nearly all households in the Cook Islands are connected to grid electricity, only 5.5% of households have additional solar photovoltaic systems installed, and 1% use small diesel generators. Several actions have taken place throughout the islands to increase the uptake of renewable energy.
[pdf] The Cook Islands in the Pacific will host a 5.6MWh lithium-ion battery energy storage system for the integration of renewables, in a project funded by the Asian Development Bank, European Union and Global Environmental Fund.
[pdf] Three newly commissioned battery systems on Rarotonga which cost US$16 million (approx. NZ$24m) will reduce the island’s dependence on oil-fuelled power generation and continue the shift to solar power.
