The first of four solar power stations commissioned under the Cook Islands Southern Renewable Energy Project will be officially opened on the island of Mitiaro this week, bringing the Cook Islands one step closer to its long-term renewable energy targets.

The Cook Islands Government aims to achieve 90% of their power needs from renewable energy by 2020. 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
Renewable Energy Opportunities and Challenges in the Pacific Islands Region: Cook Islands 1 1. Country context Physical description. The Cook Islands consist of 15 islands totalling 240 km2 of land, located in the South Pacific Ocean half-way between Tonga and Tahiti. Ap-proximately 90% of the land and population are in the
Around 4.2 MWh of energy storage capacity will be connected to a solar and diesel micro-grid on Rarotonga, the largest of the islands in the South Pacific nation. Three 40-foot containers with a total power output of 4.8 MVA will be used as a power reserve and for grid support by utility Te Aponga Uira.

renewable energy generation technology was based on the satisfactory solar resource, suitability to the site, maturity of the technology and supporting systems (including batteries), and low maintenance requirements.
The earliest sunrise of the month in Cook Islands is 5:48 AM on December 1 and the latest sunrise is 12 minutes later at 6:00 AM on December 31.. The earliest sunset is 7:08 PM on December 1 and the latest sunset is 16 minutes later at 7:24 PM on December 31.. Daylight saving time is not observed in Cook Islands during 2024. For reference, on December 21, the
Over the course of October in Cook Islands, the length of the day is increasing om the start to the end of the month, the length of the day increases by 35 minutes, implying an average daily increase of 1 minute, 10 seconds, and weekly increase of 8 minutes, 13 seconds.. The shortest day of the month is October 1, with 12 hours, 18 minutes of daylight
Infratec Chief Executive Greg Visser said the four solar plants were now providing clean, reliable and affordable energy to almost 1500 people - or about 9 percent of the Cook Islands'' population. The solar panels, which are backed by battery storage, will meet about 95 percent of the islands'' energy needs, he said.
At the 2022 United Nations Climate Change Conference (COP27) it was reported that the Cook Islands has converted 13 of its 15 islands to solar energy and set a target of 2025 for the remaining two. The target was revised to 2030 in September last year by director of Renewable Energy Development, Tangi Tereapii.
Renewable energy in the Cook Islands is primarily provided by solar energy and biomass. Since 2011 the Cook Islands has embarked on a programme of renewable energy development to improve its energy security and reduce greenhouse gas emissions, with an initial goal of reaching 50% renewable electricity by 2015, and 100% by 2020. The programme has been assisted by
As of 2022, the state of electricity consumption in the Cook Islands illustrates a balanced yet elementary mix of energy sources. Approximately half of the electricity generated comes from low-carbon sources, with solar energy contributing entirely to this segment. The other half is derived from fossil fuels, indicating that the Cook Islands is equally dependent on high-emission energy.
The Asian Development Bank and the European Union have together contributed more than $18m to get solar projects off the ground, while the islands'' government has added $5.83m. Last May, the New Zealand government completed a $20m project to build six solar arrays. Lead image: Cook Islands fishermen net fishing in Muri beach.
Renewable energy in the Cook Islands is primarily provided by solar energy and biomass. Since 2011 the Cook Islands has embarked on a programme of renewable energy development to improve its energy security and reduce greenhouse gas emissions, [1] with an initial goal of reaching 50% renewable electricity by 2015, and 100% by 2020.

The solar projects is expected to save 1.09 million liters of diesel consumption annually, and cut carbon dioxide emissions by 2,930 tons. This project will assist the Cook Islands government''s Office of the Energy Commissioner and the Renewable Energy Development Division in developing an energy efficiency policy implementation plan.
To support this ambitious plan the Asian Development Bank and the European Union fund the Cook Islands Renewable Energy Sector Project, which will construct up to six solar photovoltaic (PV) power plants with a total installed capacity of about 3 megawatts-peak coupled with battery to store electricity from solar energy.
Life in the outer islands of the Cook Islands has been transformed with the transition to clean, affordable, We never had 24-hour power then, it would run for three days a week, five days a week, and once

Solar PV: Solar resource potential has been divided into seven classes, each representing a range of annual PV output per unit of capacity (kWh/kWp/yr). The bar chart shows the proportion of a country''s land area in each of these classes and the global distribution of land area across the classes (for comparison).

The Cook Islands Electricity Sector historically been powered by diesel generators. Since around 2011, increasing solar PV generation on Rarotonga has changed this situation. And in 2014- 15, installation of 95-100% renewable solar hybrid systems on the Northern Group Islands further altered the mix.
The Cook Islands is a net importer of energy, in the form of petroleum products. Total energy consumption was 1,677,278,000 BTU (1.77 TJ) in 2017, of which 811,000,000 (0.86 TJ) was in the form of oil. In 2012 47% of imported oil was used in the transport sector, 30% in aviation, and 27% for electricity generation.
And with local residents trained during the installation process, the community is empowered to maintain and operate the systems themselves. Now with full-time power, the future has taken a new shape for Cook Islands’ residents – an improved quality of life, and increased economy activity.
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.
Now with full-time power, the future has taken a new shape for Cook Islands’ residents – 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.
Bad weather and other events often prevent goods arriving on the islands. Previously, electricity was provided by diesel generators, usually for around 12 hours per day. Power supply was effected by issues of reliability, maintainability, capacity and access to adequate, regular diesel supplies.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
