All 84 households on Hunga Island, including seven female-headed homes, are now connected to a new solar-powered microgrid, marking a significant milestone in Tonga''s
Businesses are seeking innovative models that allow them to utilise their solar power and sell any surplus to Tonga Power Limited (TPL), along with solutions to mitigate the impact of TPL''s
OIREP''s focus was installation of solar energy capabilities to nine outer islands of Tonga, with the aim of increasing the reliability, efficiency and affordability of power on these islands.
Objectives: To discuss: The recent installation of solar mini-grid systems on three remote islands in Tonga: Niuafo''ou, O''ua, and Mo''unga''one. And some case studies from Other Pacific Island
The project will supply secure, environmentally sustainable energy to homes, schools, and other public facilities, on these islands. It will quantify the solar resource and facilitate the integration
Tonga is making tangible progress toward its renewable energy targets with the rollout of solar-powered mini-grid systems across its outer islands, in a bold move to reduce its
Tonga''s solar power supply system has become a global case study for remote islands seeking energy independence. With 98% sunlight availability year-round, this Pacific kingdom now
Tonga is making tangible progress toward its renewable energy targets with the rollout of solar-powered mini-grid systems across its outer islands, in a bold move to reduce its dependence on expensive

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.
Australia also has a long history of engagement in relation to helping secure Tonga’s outer island energy needs. In the early 2000s, Australia funded the Ha’apai Outer Islands Electrification project (HOIEP), which involved the installation of diesel-powered generators and electrical reticulation on four islands in the Ha’apai group.
However, significant needs and opportunities exist to further expand renewable energy systems on outer islands. Less tangible, but also important is the role played by OIREP in consolidating Tonga’s social contract with remote island dwelling communities, by allowing for enhanced and more reliable access to electricity.
This means that little more than 30,000 people are spread across 35 islands, presenting acute issues in terms of the provision of modern infrastructure. At OIREP commencement, the ADB estimated that 89% of all households across Tonga had access to electricity.
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.
This has contributed to the Tongan economy and electricity consumers being exposed to high and volatile electricity prices due to fluctuations in the price of oil internationally. According to UK-based aggregate website Cable, Tonga's electricity is the 13th most expensive in the world, at an average cost of USD 0.35 per kilowatt hour (kWh).

The global solar folding container and energy storage container market is experiencing unprecedented growth, with portable and outdoor power demand increasing by over 400% in the past three years. Solar folding container solutions now account for approximately 50% of all new portable solar installations worldwide. North America leads with 45% market share, driven by emergency response needs and outdoor industry demand. Europe follows with 40% market share, where energy storage containers have provided reliable electricity for off-grid applications and remote operations. Asia-Pacific represents the fastest-growing region at 60% CAGR, with manufacturing innovations reducing solar folding container system prices by 30% annually. Emerging markets are adopting solar folding containers for disaster relief, outdoor events, and remote power, with typical payback periods of 1-3 years. Modern solar folding container installations now feature integrated systems with 15kW to 100kW capacity at costs below $1.80 per watt for complete portable energy solutions.
Technological advancements are dramatically improving outdoor power generation systems and off-grid energy storage performance while reducing operational costs for various applications. Next-generation solar folding containers have increased efficiency from 75% to over 95% in the past decade, while battery storage costs have decreased by 80% since 2010. Advanced energy management systems now optimize power distribution and load management across outdoor power systems, increasing operational efficiency by 40% compared to traditional generator systems. Smart monitoring systems provide real-time performance data and remote control capabilities, reducing operational costs by 50%. Battery storage integration allows outdoor power solutions to provide 24/7 reliable power and load optimization, increasing energy availability by 85-98%. These innovations have improved ROI significantly, with solar folding container projects typically achieving payback in 1-2 years and energy storage containers in 2-3 years depending on usage patterns and fuel cost savings. Recent pricing trends show standard solar folding containers (15kW-50kW) starting at $25,000 and large energy storage containers (100kWh-1MWh) from $50,000, with flexible financing options including rental agreements and power purchase arrangements available.
