Utility-Scale Energy Storage, Built for the Grid of Tomorrow
Tesseract SIGMA is a large-scale battery energy storage solution designed to support Australia’s evolving energy grid.
What is Tesseract SIGMA?
Tesseract SIGMA is a grid-connected Battery Energy Storage System (BESS) solution developed and delivered by Tesseract Energy and its investment partners.
Rather than focusing on individual components, SIGMA delivers end-to-end energy storage projects — from development and approvals through to construction, grid connection, and long-term operation.
This is energy infrastructure, designed to perform at scale.
Why Large-Scale Energy Storage Matters
Australia’s energy system is changing rapidly. As more renewable energy enters the grid, storage becomes critical.
Large-scale batteries play a key role by:
- Balancing supply and demand
- Improving grid reliability and resilience
- Supporting renewable energy generation
- Reducing reliance on fossil fuel peaking plants
- Enhancing energy security during peak demand events
Tesseract SIGMA is designed to meet these challenges — today and into the future.

01
Designed for Performance. Built for Scale.
Tesseract SIGMA projects are engineered to operate at utility scale, supporting high-voltage grid connections and delivering multi-hour energy capacity.
Each project is:
-
Strategically located near major substations
-
Designed for strong grid conditions
-
Built with scalability in mind
-
Structured for long-term operational performance
Our developments are planned to integrate seamlessly into Australia’s transmission network.
Government-Approved. Investor-Ready.
Tesseract SIGMA projects are developed to meet strict regulatory, environmental and planning standards.
Where required, projects are supported by:
-
Government approvals and sponsorships
-
Detailed environmental impact assessments
-
Grid connection studies and approvals
-
Bankable project structures
This makes SIGMA projects suitable for institutional investors, infrastructure funds, and long-term asset owners.
