Wainikasou and Nagado
Our vision: to make Fiji’s power needs self-reliant and clean.
When most people think of Fiji, they think of beach resorts and island holidays. Pacific Hydro saw a Pacific nation that was far too reliant on imported diesel fuel, and with the natural resources to develop hydro power infrastructure for a much cleaner, renewable and sustainable power source.
We formed Sustainable Energy Limited (SEL), a joint venture with the Fiji Electrical Authority, to realise the renewable energy potential of Fiji. Our aim is to develop up to 100MW of renewable energy capacity to replace the country’s dependence on imported diesel fuels.
Two projects have now been developed, the Wainikasou and Nagado hydro projects, producing a combined total of almost 9MW of power each year. SEL is now developing a third hydro plant, the 54MW Nadarivatu hydro project.
Wainikasou Hydro Project
The Wainikasou plant is located on Fiji’s main island of Viti Levu. The project has been built on existing pipelines to extract un-utilised energy from existing water flows.
The Wainikasou Hydro Project has been built around infrastructure that diverts water from Wainisavalu Creek to Lake Monasavu for use by the 80 MW Wailoa Hydroelectric Station. Initial construction of this infrastructure provided for the future addition of a micro hydroelectric station on the diversion pipeline, and this is where the Wainikasou Hydro Project has been built.
A 1.5 metre high adjustable gate has been added to the existing diversion weir to better manage water flows.

Nagado Hydro Project
The Nagado Hydro Project has been constructed on a pipeline that supplies water from Vaturu Dam to Nagado water treatment works.
Gravity-fed water passes through the turbine to generate clean electricity and then continues on to the treatment plant at Nagado.

Creating history with carbon credits
Our Fijian hydro projects are having a wider significance beyond providing local clean energy, creating jobs for Fijian workers and other community gains. They have created history under the Kyoto Protocol, as a small step to save the world’s environment.
In June 2005, Pacific Hydro negotiated the world's first bank-intermediated carbon credit transaction, securing a deal with the Netherlands-based international bank ABN Amro for the purchase of 100 per cent of the Certified Emission Reductions (CERs) created from our Wainikasou and Vaturu projects.
From Pacific Hydro’s viewpoint, the experience was significant. It has positioned us as one of the only companies with a firsthand understanding of the Kyoto Protocol’s Clean Development Mechanism (CDM) registration process and also how to structure and complete deals for the sale of carbon credits.
