The world's largest battery, powered by U.S.-based Powin, has begun construction in Australia.

Global energy storage platform provider Powin LLC (Powin), will deliver a 1.9 GWh battery energy storage system (BESS) for Akaysha Energy (Akaysha), a BlackRock company, to power the New South Wales (NSW) Waratah Super Battery (WSB) project. Following a tender process, Akaysha Energy has been appointed by the Energy Corporation of NSW (EnergyCo) to develop the Waratah Superbattery - the world's most powerful battery - to provide a service of at least 700 MW capacity as part of a System Integrity Protection Scheme (SIPS). Powin will supply 2592 Centipede power segments



and 288 power conversion systems from its wholly owned subsidiary, EKS Energy for a total project capacity of 909MW / 1915 MWh. Powin will also provide a 20-year long-term service agreement (LTSA) that will improve the reliability, efficiency and availability of the power supplied by the mega-battery.

This flagship SIPS project will free up latent transfer capacity on the existing transmission system, help integrate renewables, and maintain grid reliability by acting as a "buffer" in the event that outages such as lightning strikes or wildfires disrupt the flow of electricity. The proposed WSB project will ensure Sydney, Newcastle and Wollongong have access to more power from existing generators, while reducing the risk of power outages.

"Powin's proven ability to deploy energy storage systems at scale, coupled with EKS Energy's unrivaled capabilities in power conversion systems, plant controllers and systems engineering, have facilitated the selection of Powin as our technology partner," comments Nick Carter, CEO of Akaysha Energy. "Together, Powin and EKS are one of the few companies best positioned to meet the high performance standards of Australian grid operators, as their vertically integrated platform combining hardware and software controls enables unprecedented response time and grid compliance," he adds.

"We are honored to have been selected by Akaysha to supply the world's most powerful battery," comments Geoff Brown, CEO of Powin. "This is a pivotal time for the industry as we begin to replace carbon-emitting power plants with cleaner, more efficient and fast-response energy storage systems," he concludes.

Considered by the New South Wales Government as a state critical infrastructure (CSSI), the Waratah Superbattery will be located 100 kilometers north of Sydney, at the former 1400 MW Munmorah coal-fired power station. Pending approval, construction will begin in 2023 and is expected to be completed by mid-2025.

The Waratah superbattery is separate from the 1.7GWh supply agreement between Akaysha and Powin that was announced as early as August 2022, reinforcing the importance of energy storage to the Australian power market.
