Fortescue Future Industries 275 kV Substation Project

Overview

The FFI GEM 275kV Substation in Gladstone, Queensland, supports Fortescue Future Industries' Green Energy Manufacturing Centre, a key part of Australia's push into large-scale green hydrogen production. To ensure reliable high-voltage performance at this critical renewable infrastructure site, Insulect supplied 275kV Disconnectors, Circuit Breakers (CBs), Capacitive Voltage Transformers (CVTs), Surge Arrestors, and Station Post Insulators.

Challenge

Fortescue’s Green Energy Manufacturing Centre is designed to operate at scale and with minimal downtime, meaning the supporting substation infrastructure had to meet strict performance and safety requirements. Any failure within the 275kV network could have serious consequences for operations, safety, and project timelines. The challenge was to deliver high‑voltage equipment that could perform reliably in a coastal Queensland environment while meeting demanding technical standards. The project also required coordination across multiple components, tight construction schedules, and confidence that all supplied equipment would integrate seamlessly into the overall substation design. 

Solution

Insulect supplied a complete suite of critical 275 kV substation equipment, including:

• 275 kV Disconnectors
• 275 kV Dead Tank Circuit Breaker with POW
• 275 kV Capacitive Voltage Transformer
• Post insulators
• Surge arresters

To support successful delivery, Insulect also provided comprehensive supervision services, deploying experienced technicians to oversee installation and commissioning activities on site.

By leveraging its agile supply capability and deep technical expertise, Insulect customised standard equipment where required, ensuring full compliance with FFI’s technical specifications and site conditions.

Benefits

 The integrated equipment solution provided Fortescue with a high level of confidence in the substation’s performance. The supplied components support safe operation, reduce operational risks, and are engineered to withstand the environmental conditions associated with a coastal industrial site. By sourcing critical high‑voltage equipment from a single trusted partner, the project benefited from streamlined communication, efficient delivery, and simplified installation. This approach also supports long‑term asset reliability and aligns with Fortescue’s broader sustainability and operational goals. 

Results

With Insulect’s high‑voltage equipment successfully installed, the FFI GEM 275kV Substation is now fully equipped to support the Green Energy Manufacturing Centre and Fortescue’s renewable energy ambitions. The substation provides a stable and dependable power backbone for green hydrogen production, contributing to Australia’s clean energy future. The project demonstrates Insulect’s ability to support large‑scale, mission‑critical infrastructure with reliable solutions that help turn ambitious energy visions into operational reality.
