Construction has begun in Maryborough for Australia’s first, large-scale iron flow battery manufacturing facility, creating hundreds of jobs across the region. 

Deputy Premier and State Development Minister Steven Miles said the $70 million, state-of-the-art big battery manufacturing centre is being developed by Energy Storage Industries—Asia Pacific (ESI).

“Energy storage is key to unlocking Queensland’s renewable energy revolution as we power towards our target of having 50 per cent renewables by 2030,” Miles said.

“Queensland is becoming a renewable energy superpower and we’re well-positioned to be Australia and Asia-Pacific’s energy storage gateway.

“In the near future, power generated from a nearby wind or solar farm will be stored in iron flow batteries and help power Queensland.

“This manufacturing facility shows industry has confidence to invest in Queensland.”

In the manufacture and distribution of iron flow batteries for large-scale energy storage targeted towards wholesale electricity generators, energy retailers, and commercial and industrial customers.

The Maryborough centre is expected to be operational by 2024 and by 2026 and in a position to deliver 400MW of energy storage each year. Within 15 years it is expected to be able to supply 6GW of energy storage—or the equivalent of 20 per cent of Australia’s energy needs.

ESI is an Australian-owned, fully integrated renewable energy company that chose to base its operations in Queensland due to the state’s proactive approach to energy transition; its ability to adopt a coordinated approach via ownership of the transmission and distribution networks and the majority of baseload generation; and the proximity to the Pacific and South East Asia markets.

Even as work starts on its first facility, ESI is already assessing plans for a second Queensland facility, most likely in either Townsville or Gladstone.

By 2026, ESI expects to have around 500 highly-skilled staff and contractors working across regional Queensland. The company intends to procure up to 80 per cent of battery components within regional Queensland, further supporting regional business growth by supplying the state’s energy transition.
