Flinders Island 900x375

Flinders Island

Flinders Island has relied on diesel fuel for electricity, which was supplied by the 3 MW power station, serving 6.7 GWh of annual customer demand, peaking at 1.3 MW.  

We developed the Flinders Island “Hybrid Energy Hub” with the support of the Australian Renewable Energy Agency (ARENA). This system is capable of displacing 60% of the annual diesel fuel used to generate electricity on Flinders Island and is capable of 100% renewable energy generation. 


We integrated new renewable energy generation into the existing power system, with the support of our hybrid control system and a range of enabling technologies to ensure power system security and reliability.  

We constructed a single 900 kW wind turbine and 200 kW solar array. The enabling systems included a 750 kW/300 kWh battery, 850 kVA flywheel and a 1.5 MW dynamic resistor.  The project had a focus of making the system more readily deployable in remote locations so we designed a series of scalable modular technologies to house and ship the enabling technologies. 

Hydro Tasmania worked with Tasmanian manufacturers to fabricate these housing systems, which allow off-site manufacture and testing before shipping to Flinders Island. This ensures a speedy rollout when the systems arrive on site, reducing the risk, cost and time of construction. The modular units provide a lower cost and scalable solution that allows easy and rapid transport and installation for hybrid energy projects. They can also serve temporary uses such as in disaster relief or in the mining industry. 

Our services 

We began with the project concept, then delivered implementation, including design, construction, installation and commissioning and have an ongoing role in system performance monitoring and maintenance.  


The system contributes towards a 60% reduction in diesel consumption, reducing the cost of electricity generation for the Island.
