The Australian government has opened two CIS tenders in Western Australia, targeting 2.4GWh of energy storage and 1.6GW of renewables.

“We’re expecting the results of the Capacity Investment Scheme (CIS) Tender 3 in the coming weeks,” Thimo Mueller, general manager, commercial at ASL, said in the opening keynote of the Battery Asset Management Summit Australia 2025 this morning.

Australia’s AusEnergy Services (ASL), formerly AEMO Services, has released the Capacity Investment Scheme (CIS) Tender 6 parameters, seeking an initial 2,400MWh of dispatchable capacity in Western Australia.

“We need some form of policy or expansion of the CIS for LDES,” Nick Hawke, director of Australia’s CEFC, tells ESN Premium.

Australia’s minister for climate change and energy, Chris Bowen, has confirmed that the Capacity Investment Scheme (CIS) will be upsized from 32GW to 40GW.

Australia’s DCCEEW has announced plans to streamline the Capacity Investment Scheme (CIS) by transitioning to a one-stage process.

Developer Atmos Renewables has successfully achieved financial close on its 400MWh Merredin battery energy storage system (BESS) in Western Australia.

The Australian government is set to cut CIS tender process times to around six months as a 576MWh solar-plus-storage site has been approved in Tasmania.

2.6GWh of utility-scale battery energy storage projects have been successful in Western Australia’s first Capacity Investment Scheme tender.

On day one of the Energy Storage Summit Australia 2025, the audience heard that although 2 to 4-hour duration battery energy storage systems (BESS) are favourable, longer durations are starting to challenge this.
