URL More about Angas A-CAES (Advanced Compressed Air Energy Storage) Project – Hydrostor

The Angas A-CAES Project, located near Strathalbyn, South Australia, is Australia’s first Advanced Compressed Air Energy Storage (A-CAES) Facility. The project utilizes Hydrostor’s emissions-free, long duration energy storage technology, and is sited at a mine 50 km southeast of Adelaide—the Angas Zinc Mine, currently in care and maintenance. By selecting this site, the project will repurpose existing underground mining infrastructure as the A-CAES system’s sub-surface air storage cavern, benefiting both the electricity grid in South Australia and the local community by converting an unused brownfield site into a clean energy project that drives economic development. The 5 MW/10 MWh facility will be dispatched into Australia’s National Electricity Market (“NEM”) to provide synchronous inertia, load shifting, frequency regulation, and support grid services and reliability. It will also enable the integration of variable renewable energy resources, such as solar and wind. The project has been awarded a combined total of $9 million of grant funding from the Australian Renewable Energy Agency (ARENA) and the Government of South Australia Renewable Technology Fund and is expected to be in service in 2020.

This data has been validated by project staff through a review of publicly available information about the project, and verified by the project owner.
