HM King Tupou VI commissioned the China-Aid Tongatapu Wind Power Project today, 14 July, at Lapaha, Tongatapu. To date, the 2.25MW wind farm has generated over 2.6 million kilowatt-hours of electricity, accounting for approximately 3.8% of Tonga's total annual supply, or 25% of the annual renewable energy supply.
Construction of the wind farm began in May. 2025, funded by the People's Republic of China. Three 750-kilowatt wind turbines were installed with the construction of a 110-kilovolt switch station, and supporting transmission infrastructure, which is currently supplying clean electricity to Tonga's national grid.
The Ambassador of the People's Republic of China to Tonga, HE Liu Weimin, said: "This will significantly alleviate the long-standing electricity shortage problem in Tonga, playing a crucial role in ensuring a stable power supply for the country's development."
The wind farm was constructed by Chinese companies, including China Energy Engineering Group Hunan Electric Power Design Institute Co., Hunan Zhongtian Engineering Consulting Co., and the contractor, China Gezhouba Group Electric Power Co.
Prime Minister Hon. Dr 'Aisake Eke expressed gratitude to the PRC. "This wind farm project is a symbol of strong and growing coorporations between our two nations, grounded by mutual respect, shared aspirations and a common vision for a cleaner and more prosperous future," he said.
"This project will also help our country and global effort, to reduce dependency and reliance on imported fossil fuels, which make our people vulnerable to volatile global prices and contributing some of the highest electricity tariffs in the Pacific region."
The PM said that this wind farm project will enhance energy security and reduce greenhouse gas emissions, marking a major step toward achieving Tonga's national target of 70% renewable energy generation by 2030 and 100% by 2035.
The King was accompanied by HSH Prince Kalaniuvalu Lord Fotofili, the noble of Lapaha.
