Stanwell Corporation, a power utility owned by the government of Queensland (Australia), has commenced commercial operations at the 300 MW/600 MWh Tarong Battery. The AUD514m (US$364m) project, co-located with the Tarong coal-fired power plant, had been in construction since 2023. The battery comprises 164 lithium-ion Tesla Megapacks and will boost Tarong power plant’s overall capacity to 2.1 GW.
The Tarong Battery forms part of Stanwell’s wider 2.8 GWh battery portfolio, along with the Stanwell Battery near Rockhampton and a capacity purchase agreement for 100% of the stored energy from Quinbrook’s Supernode Stage 3 BESS at Brendale.
