    FAQs about Tonga Power Supply Solar System Model

    How did the oirep project impact Tonga?

    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.

    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.

    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.

    Why is electricity so expensive in Tonga?

    This has contributed to the Tongan economy and electricity consumers being exposed to high and volatile electricity prices due to fluctuations in the price of oil internationally. 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).

    How can oirep help Tonga's remote island communities?

    However, significant needs and opportunities exist to further expand renewable energy systems on outer islands. Less tangible, but also important is the role played by OIREP in consolidating Tonga's social contract with remote island dwelling communities, by allowing for enhanced and more reliable access to electricity.

    Why did oirep work with Tonga Power Limited?

    OIREP's on-grid work was always a matter of laying the foundations for further investment in renewables and enjoyed the ease of working through one implementing partner – Tonga Power Limited – who were incentivised to help ensure the program succeeded given they will manage all on-grid assets post-project.

  • Advantages of uninterruptible power supply

    Advantages of uninterruptible power supply

    There are three types of UPS systems that are designed to give you backup power in case of power failure or a blackout. Basically, what they do is that they act as a buffer between the utility power supply and your electrical equipment, providing power from batteries when needed. There are two types of standby systems: “offline or standby” and “line-interactive“. The difference between the two systems is in the power. As the name suggests, the online (or double-conversion) UPS power supply converts power twice (AC to DC and DC to AC) and stays always on. It also provides PFC (Power Factor Correction) within its rectifier module. As AC power gets drawn from the utility along.
