Australian renewable energy company Maoneng has secured development approval for its Gould Creek battery energy storage system project near Adelaide. The 225MW/450MWh battery will be located directly adjacent to the Para transmission substation in Playford, 22km northeast of Adelaide’s CBD.

The battery will improve electricity grid reliability and network stability by storing energy from the grid during off-peak periods and dispatching to the grid during peak periods.

Maoneng co-founder and CEO Morris Zhou said the project and would support the state’s renewable energy goals. 

“This approval is good news for all South Australians, as more battery storage will help smooth the transition to clean energy,” he said.

“South Australia has high levels of renewable energy generation, which is a positive development but can create challenges balancing supply and demand due to the intermittency of renewables. Our proposed battery storage will help manage this, supporting local energy reliability and security while also promoting greater uptake of renewables as a whole.

“We can now progress with more detailed work on our funding arrangements and supply chain, which will provide many opportunities for local businesses to get involved.”

South Australia Minister for Trade and Investment Stephen Patterson welcomed the development approval for the Gould Creek project.

“South Australia’s reputation as Australia’s leader in renewable energy investment, and our credentials of producing around 60% of our energy capacity from renewable sources, is helping to attract further investment into our state, creating jobs for our communities,” Patterson said.

“This is a significant $150 million investment by Maoneng Australia into South Australia’s sustainable future, and I’m delighted to see an Australian-owned company that is so committed to the development of projects that are critical for powering a sustainable world.”

Maoneng expects to begin construction in late 2022 with completion due a year later. Up to 160 full-time equivalent jobs will be created during this phase. The project has Crown sponsorship support from the Department for Energy and Mining.
