Reliable and flexible asset management
CGI’s Remote Telemetry Units (RTUs), also commonly known as Remote Terminal Units, form a key part of our Supervisory Control and Data Acquisition (SCADA) offering in the Australian market. They are extensively proven across Australian electricity transmission and distribution networks, providing flexibility and scalability to help support businesses in their transition to an intelligent grid.
They support utility and grid operators in significantly reducing complexity, training and lifecycle costs, resulting in an intuitive solution that is easier to engineer, operate and maintain.
Our RTUs are uniquely Australian, designed in Sydney and built in Brisbane specifically for rugged Australian conditions.
With our local manufacturing partner, we design, build and support each RTU device, and can customise the units to suit specific needs. The RTU product range also has built in cyber security to ensure safe and secure operations.

Empowering smarter, more resilient infrastructure with Australian-made RTU solutions
With over 35 years of experience, we help organisations improve the utilisation, condition monitoring, and automation of key assets.
Our RTUs support integration with SCADA systems and align with IEC standards, including IEC 61850, providing secure and reliable operations across energy networks and substations.
They enable smarter energy management through predictive modelling, remote diagnostics, and control of distributed energy resources (DERs), including community batteries.
Backed by local support and global expertise, we empower utilities to optimise performance, reduce downtime, and transition confidently to intelligent energy systems.
