Tonga’s first large scale Battery Energy Storage System to be built at the Popua Power Station, contributing to Tonga’s 50% Renewable Energy target. Akuo Energy SAS (Akuo Energy) is a renewable energy company that develops, finances, builds and operates renewable energy power plants.
The project was announced in 2018 and will be commissioned in 2021. The Popua Power Station – Battery Energy Storage System is being developed by Akuo Energy. The project is owned by Akuo Energy (100%). The key applications of the project are renewable energy integaration, electric energy time shift and grid support services.
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.
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).
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.
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.
