Atmos Renewables has reached financial close on two major energy projects supported by the Australian Government’s Capacity Investment Scheme (CIS)—the 400MW/1,600MWh Teebar Battery Energy Storage System (BESS) in Queensland and the 470MW Parron Maam Marang Wind Farm in Western Australia.
Together with the 100MW/400MWh Merredin Battery Energy Storage System, which reached financial close in June 2025, Atmos has now taken close to 1GW of CIS-backed capacity through financial close.

Located beside Powerlink’s Teebar Creek substation in Queensland’s Fraser Coast region, Teebar BESS will provide four hours of energy storage. The project will store electricity when supply is abundant and dispatch it when demand is higher, helping to support reliability and make more effective use of renewable generation.
Parron Maam Marang Wind Farm is located in Western Australia’s Wheatbelt region. The project will supply renewable electricity under a long-term power purchase agreement with Synergy, Western Australia’s largest electricity retailer.
Atmos Renewables CEO Nigel Baker said, “The CIS provides important long-term revenue support, but an award is only one step. Projects still need to secure financing, grid access, wider commercial arrangements and a credible delivery pathway.
“Teebar BESS and Parron Maam Marang Farm meet market needs for the firming and generation capacity required in Australia as electricity demand grows and ageing generation retires.
“Reaching this point has required sustained collaboration across state and federal governments, lenders, network businesses, commercial partners and delivery partners,” Baker said.
