With more than half of its electricity already supplied by wind and solar, South Australia is setting the bar high for how to efficiently decarbonize the grid. As it moves toward its 2030 target of “net” 100% renewables, the speed of the state’s energy transition will depend on a host of factors.
In the five weeks between subsidy step-down being announced and implemented under the $100 million Home Battery Scheme, more than 5,000 subsidies were approved.
SA Water has bought a significant portion of land from ExxonMobil Port Stanvac oil refinery to build a large-scale solar farm to generate energy for its neighbouring Adelaide Desalination Plant. The project is part of SA Water’s $300 million investment in solar and energy storage.
Network connection works have been completed on Neoen’s upgraded Hornsdale Power Reserve in South Australia. The 50MW/64.5 MWh expansion will provide an Australian-first large-scale demonstration of the potential for battery storage to provide the stabilizing inertia services that are critical to the future integration of renewable energy.
Virtual inertia is a fundamentally different mechanism to fast frequency response (FFR).
The South Australian Government’s subsidy under the $100 million Home Battery Scheme will have its first planned reduction in five weeks’ time.
The South Australian Government is expected to announce a decrease in the subsidy level and cap for its Home Battery Scheme this week, while the Victorian Government has more than doubled the eligible postcodes for its Solar Homes program.
South Australia is seeing a surge of small-scale utility solar as the niche, particularly around the 5MW mark, can fly under the radar of much of the electricity network’s congestion woes. The newly completed Mannum Solar Farm Project is one such example.
