Project summary
Clements Gap Battery, also referred to as Clements Gap BESS, is a 60 MW / 120 MWh battery energy storage project beside the Clements Gap Wind Farm in South Australia’s mid-north, about 20 km northeast of Port Broughton. Pacific Blue’s December 2025 update reported first energisation on 9 December 2025, major construction works complete, and the project entering commissioning. That update described staged commissioning and looked toward full operation and completion in 2026; the page timeline lists Q1 2026 for commissioning and commencement of operations as targets, not confirmed achievements.
Evidence limits and unknowns
