company news about Akaysha Energy Unveils the World's Most Powerful Battery Storage System

Project Highlights

• Current Status: The system's initial 350 MW / 700 MWh capacity is operational, acting as a critical “shock absorber” to support the grid during emergencies like lightning strikes or bushfires

• Final Scale: Upon full completion later in 2025, the facility will achieve 850 MW power output and 1,680 MWh of storage capacity—enough to energize nearly 970,000 homes for one hour
• Built for Resilience: Designed under a System Integrity Protection Scheme (SIPS), the battery delivers rapid response during grid disturbances while signaling paired generators to adjust in real time—crucial for seamless transmission load management

Strategic Significance

• .Grid Support During Coal Retirement: Positioned on the site of the decommissioned Munmorah coal power plant (100 km north of Sydney), the Waratah project helps fortify the grid as NSW phases out coal-fired power generation  
• .Economic & Operational Feat: Construction began in mid-2023 and reached mechanical completion by late 2024. The battery charges fully in just two hours and can discharge near-instantaneously, ensuring minimal disruption during peak stress period 
• .Enhancing Future Capacity: The project's “oversized” design accounts for battery degradation over time and enables Akaysha Energy to generate additional capacity revenue—helping reduce consumer electricity costs

Australia’s Waratah Super Battery is a groundbreaking leap forward for grid-scale energy storage—proving that ultra-large, fast-reacting battery systems can underpin a reliable and sustainable energy future.
