Producing energy since August this year, and providing power for up to 10,336 households, the Solar Farm is helping The Government of Tonga pursue its National Energy Roadmap plans to see up to 70% of Tongatapu’s electricity generation sourced from renewables by the end of 2025.
Renewables like solar are a significant means for Tonga to expand energy access, stabilize power grids as well as reduce pollution. Considering the shortage of solar expertise and finances for countries like Togan, the role of independent power producers and the practice of PPA provide solid support to smooth the way for solar deployment.
This solar project was completed under the partnership between Sunergise New Zealand Limited and Tonga Power Limited with support from the Asian Development Bank (ADB). Sunergise led the construction and meanwhile united local Tongan civil, mechanical and electrical sub-contractors to the team.
As Hu'akavameiliku, Prime Minister of Tonga said at the ceremony: "The successful completion of the Sunergise's 6MW Independent Power Producer solar generation system today, demonstrates the major role renewable energy independent power producers play towards achieving our 70% target by [the] end of [the] year 2025."
In the presence of Their Majesties King Tupou VI & Queen Nanasipau’u, The King & Queen of The Kingdom of Tonga, Tonga’s new 6MW solar power plant was officially launched today at Fualu, Tongatapu by Prime Minister of the Kingdom of Tonga, Hon. Hu’akavameiliku.
The Sunergise Tongatapu Solar Farm is the largest in the South Pacific. It was built as part of a power purchase agreement between Sunergise New Zealand Limited, a Todd Corporation solar company and Tonga Power Limited, with support from the Asian Development Bank.
