Tonga Photovoltaic Energy Storage

A solar-plus-storage project combining 300kW of PV and a 2MWh battery energy storage system (BESS) has been installed in the Polynesian archipelago nation of Tonga. The project on the island of Vava’u was commissioned by Tonga Power Limited (TPL), the country’s sole electric utility, on 14 March. Battery energy storage system (BESS) firm Eku Energy has announced that it has acquired Bluestone Energy''s BESS portfolio. Aura Power lands planning consent for two solar projects ... EDF''s first utility-scale solar PV power plant in the UK began generating electricity last year, triggering a £20,000 per annum community benefit fund.

Can Tonga's power infrastructure stand up against cyclones & storms?

To address the dual challenges of climate change and energy security, the Government of Tonga confirmed the Renewable Energy Act in 2008. 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.

Why is energy security important in Tonga?

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.

How will Trep help Tonga?

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.
