Tonga: Renewable Energy Project
Tonga Renewable Energy Project (TREP) has three components: (i) a large BESS capacity on Tongatapu to ensure that the intermittent electricity generated from solar photovoltaic and wind power to be funded by private independent power producers can be stored and used overnight without negatively affecting Tonga Power Limited's grids; (ii) electricity generation from the most feasible renewable resources in Tonga in Eua and Vava'u islands, and in five outer islands (O'ua, Tungua, Kotu, Mo'unga'one, and Niuafo'ou); and (iii) grid technologies and management upgrade to adapt to new electricity sources in five outer islands. The project also includes capacity building and project management support, with an emphasis on providing women with training and economic empowerment opportunities.

| Project Rationale and Linkage to Country/Regional Strategy | TREP will help Tonga rapidly move from its heavy dependence on imported fossil fuels for power generation (about 90%) to using clean and renewable energy resources that are low carbon and climate resilient. TREP will also provide technical solutions, such as a battery energy storage system, and capacity building for promoting more private sector investments in renewables, which will help Tonga meet its 50% renewable energy target by 2020 and 70% by 2030. TREP will also increase energy access of marginalized populations in the outer islands, where access is low and limited. | ||||||||||||
| Impact | Reduced Tonga's dependency on imported fossil fuel for power generation |
