FAQS about Cook Islands Base Station Energy Management System Hybrid Power Supply

Who imports the fuel in Cook Islands?

85% of the country's fuel and all of its jet fuel is imported by Pacific Energy. The Energy Act 1998 established an Energy Division within the Ministry of Works, Energy and Physical Planning (now Infrastructure Cook Islands) responsible for energy policy and electricity inspections.

How was electricity produced in the Cook Islands?

Electricity in the Cook Islands was historically produced by diesel generators on each island. Fuel was imported from Auckland and required long sea voyages to get to the northern atolls, resulting in high costs and occasional supply disruptions.

What is the future of power in the Cook Islands?

Now with full-time power, the future has taken a new shape for Cook Islands’ residents thanks to government renewable energy – leading to an improved quality of life, and increased economy activity. The improved livelihood in the communities that now have the benefit of reliable, 24hour power supply is immeasurable.

How much electricity does the Cook Islands use per capita?

Per-capita electricity consumption is approximately two-thirds that in the European Union. Greenhouse gas emissions total 88,810 t per year, or 10.36 t per capita. Electricity in the Cook Islands was historically produced by diesel generators on each island.

How did we help the Cook Islands Government achieve its aim?

We helped the government realise its aim. To support the Cook Islands Government, the New Zealand Government – through the Ministry of Foreign Affairs and Trade, installed mini-grid photo-voltaic power systems in a number of villages on six remote islands. We helped manage this logistically enjoyable project.

How did power supply affect the islands?

Power supply was effected by issues of reliability, maintainability, capacity and access to adequate, regular diesel supplies. There were no sources of hard aggregate for concrete or reliable earthmoving equipment on the islands, so all materials, equipment and tools required for construction were supplied via a freighter.
