Energy self-sufficiency has been defined as total primary energy production divided by total primary energy supply. Energy trade includes all commodities in Chapter 27 of the Harmonised System (HS).
There are three main sectors dependent on imported energy in the Cook Islands; these include transport, electricity and aviation. Of the total number of imported fuels into the country, 43% is used by transport; 30% by aviation and 27% by electricity.
The Cook Islands has a financially healthy electricity sector with technical and commercial challenges requiring on-going investment. With the exception of Pukapuka, Nassau and Suwarrow, the Cook Islands has some form of electricity network. Power supply on Rarotonga is the responsibility of the government-owned utility Te Aponga Uira (“TAU”).
Pricing is a key tool for influencing consumer behaviour. An appropriate price needs to be set that encourages energy efficient behaviour and reduces the costs to the Government, whilst also achieving its vision of reducing the costs of living and business for residents and attracting Cook Islands people to live and invest in their homeland.
In future, new energy technologies such as marine energy may offer new opportunities for the Cook Islands to generate electricity from other renewable sources. Developments in energy storage or in energy efficiency may also further reduce the Cook Islands' reliance on diesel. The Cook Islands prefers to use proven and economic energy technologies.
Energy is a fundamental prerequisite to the sustainable socio-economic development of a nation. As such, the Cook Islands Government considers that environmental protection, energy security and economic growth are inseparable key pillars of our country's development.
The Cook Islands has abundant solar radiation, which makes solar electricity PV an attractive option. On average, about 80 percent of households already use solar water heating, and we are committed to increasing the use of photovoltaics for electricity generation and to reduce reliance on diesel.

Take a look at the monitor and get an insight into the sustainability potential of your business park. The entrepreneurial and industrial character of business parks may provide a major impetus to the energy transition for companies and the surrounding area. In the quick-start guide drawn up by TNO, we identify 5 factors for success:
Business parks can play a major role in the energy transition. The grouping of many businesses on one site usually leads to a high, concentrated energy demand. As a result, there are entrepreneurs who have taken the lead in collaborating with each other to become more sustainable. Such collaborations make collective solutions promising.
In order to transfer and store energy, different models can be used. Mukisa et al. (2020) proposed the store-on-grid scheme model. That model makes priority for self-consumption of the self-generated energy before the electricity is fed to the electricity grid. That will minimize the consumption of electricity produced from non-renewable sources.
Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
