  • Fluence to supply Gridstack™ BESS and 20-year services for the Wellington Stage 1 project
  • Intelligent software suite includes Mosaic for bidding and Nispera for asset management
  • Project scheduled for energization in 2026; targets grid stability and renewable integration

Fluence Energy, Inc. (NASDAQ: FLNC) has been chosen by AMPYR Australia to deliver a 300 megawatt / 600 megawatt-hour battery energy storage system (BESS) for the Wellington Stage 1 project in New South Wales. The project marks AMPYR’s first grid-scale battery to reach financial close in Australia and is set to become operational in 2026.

Under the contract, Fluence will provide its Gridstack™ grid-scale energy storage product, a 20-year service and maintenance agreement, and deploy two of its software platforms: Mosaic, for AI-powered bidding and market participation, and Nispera, for asset performance management.

The Wellington Stage 1 BESS is designed to support Australia’s National Electricity Market (NEM) by enhancing flexibility, improving reliability, and facilitating the integration of renewable energy. Fluence’s Mosaic platform will manage AMPYR’s virtual tolling contract, allowing real-time optimization of charging and discharging decisions. Nispera will provide performance analytics and operational insights to support system uptime and efficiency.

According to Fluence, the project aligns with its broader efforts in Australia, where it already has four BESS sites in operation, two more approaching launch, and several additional projects in development.

AMPYR Australia, backed by AMPYR Global and AGP, is targeting 6,000 megawatt-hours of operational grid-scale storage by 2030. The Wellington project represents an initial step toward that goal, contributing to the country's broader transition to reliable and renewable energy infrastructure.

Fluence Energy delivers energy storage solutions and optimization software across nearly 50 global markets. Its platforms support renewable asset integration, grid resilience, and performance-driven energy deployment at utility scale.
