Hydrostor

Angas A-CAES Project

About the project

Hydrostor’s Angas Project is Australia’s first Advanced Compressed Air Energy Storage (A-CAES) facility. The 5 MW facility will be dispatched into the National Electricity Market (NEM) to provide synchronous inertia, load shifting, frequency regulation, and support grid security and reliability. It will also enable the integration of variable renewable energy resources, such as solar and wind.

  • Location: Strathalbyn, South Australia, Australia
  • Capacity/Energy: 5 MW, 10 MWh
  • Owner: Hydrostor, dispatched into the National Electricity Market (NEM)
  • Application: Load leveling, frequency response, inertia
  • In-service:2020 (exptected)
  • Location: Strathalbyn, South Australia, Australia
  • Capacity/Energy: 5 MW, 10 MWh
  • Owner: Hydrostor, dispatched into the National Electricity Market (NEM)

  • In-service: 2020 (expected)

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. Hydrostor acknowledges Terramin Australia Limited support in developing this project and its beneficial application to South Australia.

Project Location

The Angas A-CAES Project will be sited at a mine 50 km southeast of Adelaide—the Angas Zinc Mine near Strathalbyn, 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 project’s proximity to Adelaide will enable the system to deliver substantial value to the South Australian electricity network.
