Ampyr Seeks Federal Approval for NSW Battery Project
March 24, 2026
Ampyr, led by former AEMO executive Alex Wonhas, has submitted a federal environmental assessment referral under the Environment Protection and Biodiversity Conservation Act (EPBC Act) for the Swallow Tail battery project in New South Wales. This 375 MW, 1,500 MWh big battery project, awarded under the third Capacity Investment Scheme (CIS) tender in 2025, aims to begin construction in October 2026. The project is designed to minimize environmental impacts by progressively rehabilitating the site during construction and restoring disturbed areas upon completion. It will connect to key transmission infrastructure including the Bannaby substation and Humelink and Southern Sydney Ring transmission lines.
- Why this matters: This federal environmental referral is a critical step for Ampyr to secure regulatory approval and proceed with construction, signaling advancing opportunities in large-scale energy storage procurement under the CIS program.
- Procurement professionals should note the integration of environmental compliance with infrastructure development, highlighting the importance of early engagement with EPBC Act requirements.
- Contractors and suppliers can anticipate demand for construction, environmental management, and grid connection services in New South Wales starting late 2026.
- This project exemplifies the growing federal support for battery storage solutions to enhance grid reliability and capacity, indicating expanding market opportunities in renewable energy infrastructure procurement.
The project area would be progressively rehabilitated throughout construction. When construction is completed, temporary plant and equipment will be removed, and disturbed areas will be revegetated and rehabilitated.
