In brief:

  • The Big Canberra Battery has reached a milestone with a transformer delivered to site.
  • The transformer ensures electricity stored in the battery is converted to the correct voltage for safe use in the grid.
  • The Big Canberra Battery will help deliver clean, reliable power and create jobs for the community.
  • The Big Canberra Battery is on track to be operational in 2026.

The Big Canberra Battery project has reached another milestone.

A transformer was delivered to the Williamsdale construction site this week.

The transformer makes sure the electricity stored in the battery is converted correctly to be safely supplied to the grid.

This renewable energy will power Canberra homes and businesses when demand is high and solar generation drops.

The Big Canberra Battery

The Big Canberra Battery will give the community energy security by keeping their power running, while helping reduce emissions.

The large-scale battery will deliver at least 250 megawatts of power.

This is enough stored renewable energy to power one-third of the city for two hours during peak demand.

It will help:

  • reduce reliance on fossil fuels
  • secure a reliable and affordable electricity system
  • help the ACT’s transition to net-zero emissions
  • generate revenue for the ACT
  • create local jobs.

The ACT Government has partnered with Eku Energy on the large-scale battery energy storage system.

Construction of the battery is underway. It is on track to be operational in 2026.

Additional benefits

The battery will help deliver clean, reliable power and create jobs for the community.

The project will support 150 local jobs in the emerging clean energy sector.

Battery storage technology is a key component of the ACT’s net-zero emissions future.
