The Australian Renewable Energy Agency (ARENA) has announced that up to $40 million in funding is available for the development of the first pumped storage project in South Australia.
The funding will be issued on behalf of the Australian Government and is expected to go towards a project that will be at least 200 MW in capacity, and with the ability to reach financial close by 30 June 2020.
Four proposed large-scale pumped storage projects in development in South Australia have sought ARENA funding, and have been assessed favourably under its Advancing Renewables Program.
ARENA will invite these projects to put forward proposals for further assessment that outline how the project will reach financial close, and includes their lowest funding request from ARENA.
After proposals are received by October, ARENA will undertake further assessment and due diligence on the four advanced projects to select a single funding recipient, with a funding decision to be made by late 2019.
ARENA will work with both the Australian Government’s Underwriting New Generation Investments (UNGI) program which has shortlisted 12 projects including six pumped storage projects, of which three are in South Australia, and the South Australian Government’s $50 million Grid Scale Storage Fund (GSSF) to support the development of PHES in South Australia.
As South Australia continues to increase its renewable energy make up, large-scale storage such as pumped storage and grid-scale batteries are needed to supply system strength, energy reliability and inertia to the region.
The development of a large-scale pumped storage plant would balance and firm up variability in the South Australian National Electricity Market region, providing a range of services to support grid reliability and security – including essential stability services as well as “intra day” storage for six to eight hours duration.
ARENA CEO Darren Miller said pumped storage will play a growing role as the share of renewables increases: “With 50 per cent of total energy generation in South Australia coming from variable renewable energy in 2018, and an expectation that this will increase in the next two years, there is an increasing requirement for energy storage to firm and balance the system in that state. As part of this, pumped hydro has an important role to play in Australia’s energy transition.
“Several potential pumped hydro projects are being developed in South Australia, which are well advanced and have been rigorously assessed as high merit. Based on the market need and high construction costs, we expect to fund only one project at this stage,” he added. “This funding envelope, and this further assessment, is designed to ensure the best project proceeds with the least Government support.”
ARENA has previously supported a range of pumped storage feasibility studies including Snowy 2.0, Hydro Tasmania’s Battery of the Nation initiatives that include potential pumped storage sites, Genex’s Kidston Stage 2 facility in Queensland and the proposed expansion of Origin’s Shoalhaven plant in NSW.
