In 2022, Tonga’ economy was ranked 184th in the world in gross domestic product (GDP). The country’s economy is dependent on the export of crustaceans, fruits, nuts, vegetables, and cassava.

Environmental Policies

In 2016, Tonga signed the “Paris Climate Agreement, committing to generate 70% of the nation’s electricity from renewables by 2030. Tonga also committed to improve energy efficiency by reducing electricity line losses to 9% from 18% by 2020.

Power Generation Capabilities

In 2021, 100% of the people in Tonga had access to electricity. In 2021, the state-owned Tonga Power Limited used refined petroleum (87.5%) and renewable energy (12.5%) to generate electricity in the country. Solar is the dominant type of renewable energy used to generate electricity in Tonga.

Recent renewable energy projects in Tonga include:

  • 10 MW Wave Energy Project – In March 2023, the government of Tonga announced that Irish company Seabased would develop a wave power project off the main island of Tongatapu.
  • 9 MW Solar Project In August 2022, Tonga Power Limited commissioned the Sunergise Tongatapu Solar Project on the main island of Tongatapu.


Tonga imports refined petroleum for power generation, heating, and transportation. In 2021, Tonga imported U.S.$ 30.3 Million in refined petroleum.

On 24 February 2022, Russia invaded Ukraine, prompting the European Union, United Kingdom, United States, Canada, Japan, South Korea, Australia, and New Zealand to place economic sanctions on Russian imports and exports. As a result, the crude oil and natural gas prices increased by over 50% from May 2021 to May 2022.

Tonga has significant undeveloped renewable energy resources, including solar, offshore wind, onshore wind, wave energy, and biomass. Tonga’s renewable energy resource potential could easily generate 100% of the nation’s electricity requirements. Volatile oil prices accelerating the Kingdom of Tonga’s move to renewable energy.
