Headline: Monasavu hydro-power project opened as turning point in Fiji’s energy future
In October 1983, Fiji marked a watershed moment when the Governor General, Ratu Sir Penaia Ganilau, officially opened the Monasavu hydro-power project. Water from the dam flowed to turbines, sending electricity across Viti Levu as Prime Minister Ratu Sir Kamisese Mara stood nearby at the ceremony marking Fiji’s own homegrown electricity.
Ratu Sir Penaia unveiled commemorative plaques at the Monasavu Rock and later at the Wailoa Power Station, where a ribbon was cut and a button pressed to activate hydroelectric power for the first time in Fiji. More than 500 guests attended as the turbine began generating 45 megawatts of power. In his remarks, Ratu Sir Penaia said the project would have far-reaching consequences for Fiji’s future, calling it an answer to the energy crisis and a vital step in the nation’s post-oil economic orientation. He framed the Monasavu hydro-project as a true national undertaking and paid tribute to the workers who lost their lives during construction, recognizing their role in Fiji’s pursuit of a better quality of life.
The dam stands about 82 metres high and was built largely with local materials, comprising more than three million tonnes of clay and gravel rock. The impounded water created a 17-kilometre-long lake spanning some 470 hectares, believed to be the largest man-made lake in the Pacific region. Government officials credited local labor with completing the project ahead of schedule and said it would shape Fiji’s energy landscape for years to come.
As Fiji looked to the future, the Government signaled continued efforts to reduce dependence on imported fuel, including measures related to fuel pricing procedures, while acknowledging that hydro-electric power was just one part of a broader energy strategy.
Context and continuing momentum in Fiji’s renewables era
Fiji’s energy story has since evolved with a broader push toward renewable sources. Later initiatives highlighted in recent years include solar power projects like the Duadua Resort’s solar facility in Rakiraki, designed to supply the resort and feed excess energy back to the national grid, and a growing emphasis on green hydrogen and other clean-energy solutions as part of a national strategy to diversify energy sources and cut emissions.
Current policy aims have set ambitious targets to expand renewable electricity generation—reflecting a continued commitment to energy security, climate responsibility, and sustainable growth for Fiji’s communities. Initiatives involving solar, hydrogen, and other renewables illustrate a longer arc from Monasavu’s 1983 milestone toward a greener, more resilient energy system for the Pacific region.
Additional context and value points
– Monasavu’s opening is a historic milestone that demonstrated local capability in a major national project, involving significant community and labor contributions.
– The project’s scale and the resulting lake reshaped geography and regional planning, setting precedent for future infrastructure investments in Fiji.
– The continued emphasis on diversifying energy sources aims to reduce exposure to fuel price shocks and environmental costs, while supporting rural and urban electrification.
– The broader renewables narrative in Fiji includes pilot hydrogen projects and solar installations that seek to balance reliability, cost, and sustainability as the country pursues its long-term climate and energy goals.
Key facts to remember
– 45 megawatts of hydropower generated at commissioning
– Dam height: approximately 82 metres
– Lake created: 17 kilometres long, about 470 hectares
– Construction used more than three million tonnes of local clay and gravel rock
– Commemorative plaques and ceremonies at Monasavu Rock and Wailoa Power Station
– More than 500 guests attended the opening
– Project cited as a national undertaking and a response to the post-oil era and energy security concerns.
Monasavu’s successful completion and commissioning underscored Fiji’s capability and resolve to build large-scale energy infrastructure locally. It established a foundation for ongoing diversification into renewables, a trajectory that modern Fiji continues to pursue through solar, hydrogen, and other innovations to enhance energy security and support sustainable development.
