Australian-owned renewables and battery storage developer Maoneng has revealed plans for three big battery storage projects totalling 900MWh in the New South Wales New England region and in the state’s north, targeting one of the government’s key zones for renewables development.

Planning applications filed by Maoneng outline plans for a 200MW/400MWh big battery near Tamworth, and a 150MW/300MWh battery near Armidale, and a 100MW/200MWh big battery near Lismore in the state’s north.

The new proposals join Maoneng’s existing plans for a 240MW/480MWh big battery on the Mornington Peninsula in Victoria and a 225/450MWh big battery at Gould Creek in South Australia. In NSW the company is contracted to deliver 200MW/400MWh of battery storage for AGL between 2023 and 2028.

The Tamworth Battery Energy Storage System and Armidale Battery Energy Storage System will both be focused on providing “reliability and security” to the network during peak periods.

Maoneng has also flagged that its battery projects – at least the Mornington Peninsula one, for starters – would use lithium iron phosphate (LFP) chemistries because of their strong safety performance.

Maoneng’s head of renewables development, Allison Hawke, said the company was aiming to start construction on the newly announced NSW batteries in early 2023 and have them finished later in the same year.
