OIREP''s focus was installation of solar energy capabilities to nine outer islands of Tonga, with the aim of increasing the reliability, efficiency and affordability of power on these
With Tonga aiming to achieve 70% renewable energy by 2025, this solar energy storage tender represents a critical step toward energy independence. The island nation currently relies on

Australia also has a long history of engagement in relation to helping secure Tonga’s outer island energy needs. In the early 2000s, Australia funded the Ha’apai Outer Islands Electrification project (HOIEP), which involved the installation of diesel-powered generators and electrical reticulation on four islands in the Ha’apai group.
This means that little more than 30,000 people are spread across 35 islands, presenting acute issues in terms of the provision of modern infrastructure. At OIREP commencement, the ADB estimated that 89% of all households across Tonga had access to electricity.
According to UK-based aggregate website Cable, Tonga's electricity is the 13th most expensive in the world, at an average cost of USD 0.35 per kilowatt hour (kWh).
The project achieved its proposed impact, in terms of helping Tonga reduce its dependence on imported fossil fuel for power generation with OIREP assets estimated to have reduced diesel usage by 0.5 million litres annually. Central to the project outcome was the provision of on-grid and off-grid generation solar power at reduced cost.
