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 |

| Description of Project Outputs | Battery Energy storage system (BESS) facilities on Tongatapu installed Grid-connected renewable energy generation on 'Eua and Vava'u installed Renewable-based hybrid systems and mini-grids on outer-Islands installed Strengthening of capacity building installed |
| Status of Implementation Progress (Outputs, Activities, and Issues) | Achieved - BESS on Tongatapu completed Nov 2021 and commissioned Oct 2022. Achieved - Eua and Vavau commissioned March 2023. Renovation works to TPL's Control Room in Eua is ongoing.Ongoing - a contract to construct renewable energy-based hybrid mini-grids on 4 Haapai outer islands and Niuafoou was awarded in Mar 2020 but delayed faced due to COVID-19 pandemic and finalization of contract variations which was completed in April 2023. Local sub-contractor mobilized to start site preparatory works in June 2023. Main contractor mobilizing to Niuafoou in September 2023. A contract to construct mini grids on 4 Vavau outer islands was awarded in July 2023 and the contractor will mobilize in December 2023. 2 contracts to modernize TPL's control centre are ongoing.Work by the PMU consultants and the Consultancy Services Contract firm continues. 2 consultants for the independent power producer transaction advisory services continue to work with TPL to achieve Tonga's 80% renewable energy target. |

ADB, Australia, GCF, Tonga Open Renewable Based Mini-Grid to Deliver Clean and Affordable Electricity to Vava’u
ADB and the governments of Tonga and Australia commissioned the Vava’u hybrid mini-grid as part of the cofinanced Tonga Renewable Energy Project. The new grid, which is cofinanced by the Green Climate Fund, will provide clean, reliable, and efficient electricity supply to the people and businesses of Vava’u.
How ADB is Helping Power the Pacific
In the Pacific, power is life. Reliable electricity allows hospitals to conduct life-saving surgery, keeps food and medicine fresh and sanitary, and keeps street lights on to make neighborhoods and communities safer.Q&A: In Tonga, More Resilient Power Infrastructure Isn’t Only About More Reliable Electricity—it’s About Saving Lives
ADB, Dr. ‘Ana talks about the challenges of operating a hospital with an unreliable power supply and how Tonga’s more resilient infrastructure has benefited the lives of doctors and patients in Vaiola Hospital.A power of good: How ADB's climate-resilient investment is boosting Tonga's energy future
Energy security is an ever-present concern for Tonga. To address the dual challenges of climate change and energy security, the Government of Tonga confirmed the Renewable Energy Act in 2008.
For Tonga, a Power Supply That can Withstand a Cyclone is a Matter of Life and Death
Investment from ADB and other partners is making sure Tonga’s power infrastructure can better stand up under the cyclones and storms that are a part of life in the Pacific.ADB, Tonga Sign Grant Agreement to Develop Renewable Energy
Three grant agreements that will fund the development and implementation of renewable energy projects in Tonga, which will enhance the country’s energy security and reducing carbon emissions, were signed today.
