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.

Supporting Australia’s Energy Transition

Tesseract SIGMA is part of a broader commitment to building a cleaner, more resilient energy system.

  • By investing in large-scale storage, we help:
  • Enable higher penetration of renewable energy
  • Strengthen grid stability
  • Support national decarbonisation goals
  • Create long-term energy infrastructure assets

This is not short-term energy.

This is future-proof infrastructure.

Part of the Tesseract Energy Ecosystem

Tesseract SIGMA sits alongside our broader energy solutions, including:

  • Tesseract ZERO – residential clean energy plans

  • Tesseract ESS – commercial & industrial energy storage

  • Tesseract SOLAR – solar energy services

Together, these solutions form a complete energy ecosystem — from homes to the grid.
