State-owned company WaterNSW has confirmed it is exploring opportunities to implement pumped hydro energy storage (PHES) across 41 of its dams in New South Wales, Australia.

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.

Developers entering competitive solicitations for energy storage have been offered advice on how to be successful.

Thimo Mueller of AEMO Services, believes the value of energy storage in Australia will be higher than investor expectations.

The Australian Energy Market Operator (AEMO) Services has revealed that nearly 14GWh of long-duration energy storage (LDES) projects were successful in the latest New South Wales Roadmap competitive tender.
