The Flavian Superhybrid project

A family at sunset.

In early May 2022, Sunshine Hydro launched our $2b ‘Flavian’ hydropower project near Miriam Vale within the Central Queensland Renewable Energy Zone (REZ).  

Flavian green hydropower will generate reliable power to the grid, along with green hydrogen production.   

Through green hydrogen production we will also provide green energy to power the equivalent of 1,000 heavy trucks per annum. 

We will apply a world leading, innovative closed loop pumped hydro system, which efficiently selects of a clever mix of energy inputs, outputs, and storage to “keep the lights on”. 

Green, reliable renewable energy  

Our unique green energy ecosystem will provide highly reliable baseload renewable energy which does not rely on sun and wind. 

The Flavian hydropower will abate on average 4 million tonnes of carbon per year. This is around 2.5% of the Queensland’s current level of annual carbon emissions. 

Our project will also generate cheaper energy to place downward pressure on energy prices.

Fast facts

About Sunshine Hydro

We are an emerging Australian renewable energy company, ready to apply world leading hydropower technologies.  

Our vision is to keep the lights on through the delivery of 100% renewable energy to power industry and energy networks 24/7 and to play a key role in decarbonising the world’s energy systems. 

We are focused on generating large-scale ‘firm’ (reliable) green baseload energy through our unique Superhybrid hydropower model to meet long term consumer demand, as our economy and society seeks to decarbonise. 

Over recent years we have invested in R&D, such as the AESOP software, and undertaken extensive research and site appraisal to be ready to progress our first project in Queensland. 

We also have many prospective projects elsewhere in Australia and abroad.

How it works

The Sunshine Hydro hydropower technique involves creating and connecting an upper and lower water storage.  

Using renewable energy, water is pumped to the higher storage and then released to flow under gravity through turbines to generate electricity.  This energy can be sent to the grid or power the production of green hydrogen. 

The water is collected in the lower reservoir, ready to pump to the higher reservoir with renewable energy sources. This is the green closed loop hydropower system in action. 

While we will input renewable energy into our Flavian Superhybrid model, no wind or solar energy infrastructure will be located on the project site, or nearby. 

Superhybrid technology with wind, solar, pumped hydro, electrolysis and liquefaction.

Project timing

Project timeline - launch 2022, approval and planning 2033 - 24, project approvals completed 2024 - 25, Construction 2026 - 28, First renewable energy production 2028.

Delivery through partnerships

We are partnering with Energy Estate, a renewable energy and green hydrogen developer to provide initial green energy to power the Flavian project.  


We also have valuable partnerships with Burnett Mary Regional Group BMRG, and the traditional owners, the Gidarjil Development Corporation.   

Through these strong partnerships, we will deliver one of the world’s most sustainable renewable energy projects, and extensive conservation and biodiversity outcomes across the site. 

We will announce further partners and key suppliers as the project progresses.

News and media

The Flavian project, Sunshine Hydro and our project partners acknowledge the traditional owners of this land the Bailai (Byellee), Gooreng Gooreng, Gurang and Taribelang Bund people, who are the traditional custodians of the land on which we operate, and their continuing connection to land, water and community.

We pay our respects to them and their cultures and to Elders past, present and emerging.
