Yadlamalka Energy is an innovative renewable energy project in South Australia, comprising co-located Vanadium Flow battery energy storage (2MW – 8MWh AC) and Solar Photovoltaic (PV) farm (6MWp DC), integrated behind a DC-coupled inverter. It is located at the Neuroodla electricity substation, near Yadlamalka sheep station about 80km north of Port Augusta, South Australia, an area with very favourable solar radiation.
The project will supply a combination of solar power and battery storage services to the grid. The vanadium flow battery will take advantage of the significant intraday price variation in South Australia to time shift power from midday to peak periods in the evenings and mornings. The project will also participate in the Frequency Control Ancillary Services (FCAS) market which helps maintain stability of the electricity system.
Through using breakthrough technology in the form of vanadium flow batteries, we can deliver strong, economic infrastructure benefit to South Australia and at the same time support a low carbon economy.
Vanadium flow batteries are fully containerised, non-flammable units reusable over semi-infinite cycles, able to discharge 100% of the stored energy and do not degrade. In the words of Barack Obama “They are the multi-mega watt energy solution” and “one of the coolest things” he has ever spoken about!
Vanadium flow batteries have significant advantages over lithium in longer duration time shifting applications. Our batteries will be able to discharge at a power of 2MW per hour for four hours. They are suitable for heavy cycling because, unlike lithium, they do not degrade. We plan to fully charge and discharge the battery at least once a day and possibly twice, depending on pricing conditions.
The Yadlamalka Energy project will contribute to solving the distributed and intermittent energy problems that exist in South Australia, which are expected to intensify as we rely more and more on renewable energy sources. It will commercialise breakthrough technology to help meet Australia and the world’s future energy needs.
