Japan funds solar power systems to strengthen Tonga''s disaster
Japan and Tonga have signed a new agreement aimed at boosting the Pacific nation''s disaster resilience through the installation of solar-powered infrastructure to support
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).
From July 2020 to June 2021, users on the main island of Tongatapu paid on average a 6% subsidy to cover the costs of outer islands, with the result being that Vava'u, Ha'apai and 'Eua received 40%, 40% and 26% subsidies respectively.
