Technical FAQs 4

What is the Tonga solar project?

1. The project will construct and install solar power systems with a total capacity of 1.32 MWp on the outer islands of Tonga, and the existing grid network on the islands of Vava'u and 'Eua rehabilitated by TPL. (The rehabilitated grid network portions on Vava'u and 'Eua are expanded). 2.

How many MWp of power will be built in Tonga?

1. THE PROJECT WILL CONSTRUCT AND INSTALL POWER SYSTEMS WITH A TOTAL CAPACITY OF 1.32 MWp ON THE OUTER ISLANDS OF TONGA, AND THE EXISTING GRID NETWORK ON THE ISLANDS OF VAVAU AND EUA REHABILITATED BY TPL (THE REHABILITATED GRID NETWORK PORTIONS ON VAVAU AND EUA ARE EXPANDED). (Phase 1): The plants have been built and are operational.

Can Australia help secure Tonga's outer island energy needs?

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.

How many people have access to electricity in Tonga?

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.
