Two new big battery energy storage systems under development in Queensland and New South Wales have recently taken important next steps towards construction, signing battery suppliers and an EPC provider.
Sydney based renewable energy company Atmos Renewables announced that it had reached financial close on the 400-megawatt (MW)/1,600-megawatt-hour (MWh) Teebar Battery Energy Storage System (BESS), a four-hour battery to be built in central Queensland.
Located around 60 km west of Maryborough, the Teebar BESS is backed by the federal government’s Capacity Investment Scheme (CIS).
In a new update on the project last week, Atmos announced that Australian construction firm Enerven would deliver balance-of-plant works, and Finnish energy storage giant Valo was locked in as its battery supplier.
Enerven will be responsible for site preparation including local road upgrades and construction of facilities, along with BESS integration, and delivery of a 275 kV substation and approximately 300 metres of 275 kV overhead transmission lines.
This will be Enerven’s first major project in Queensland and its first in partnership with Atmos Renewables.
Valo will supply its GridSolve Quantum2 energy storage system as well as its GEMS software, which combines energy management with advanced power plant control to optimise performance, support grid requirements, and maximise asset value.
Valo will also provide long-term service including maintenance, remote operational support, software updates, and performance monitoring.
Enerven will begin work on the site this year, with delivery of battery storage systems following and commercial operation currently targeted for late 2028.
The announcement comes less than a fortnight after Valo was launched as a joint venture between Wärtsilä and RCT Solutions GmbH with over 20 gigawatt-hours (GWh) already in operation around the globe.
Also announced last week, Swedish developer OX2 selected e-Storage, a subsidiary of Canadian Solar, as the supplier for the Muswellbrook Solar Farm and Battery in New South Wales.
Set to be built on the site of a former Muswellbrook coal mine, the Muswellbrook Solar Farm and Battery will consist of a 135 MW solar farm and a 100 MW/200 MWh BESS.
Canadian Solar’s e-Storage will supply its SolBank 3.0 battery containers, to be paired with Power Conversion Systems (PCS), plant controls, and its proprietary EQ-S Energy Management System (EMS).
Shipments are expected to begin in the third quarter of 2027, with commercial operation currently targeted for the third quarter of 2028. Construction at the site has already begun.
