Substations are critical assets in the electricity system. They transform voltage, protect equipment, support network operations and connect generation, transmission and distribution infrastructure.
Omexom Australia supports customers with high-voltage substation construction, testing, commissioning, operation, maintenance and upgrade works.
Our capability includes primary plant, protection and control systems, electrical installation, testing and commissioning coordination, protection and control panel manufacturing support and operational support for high-voltage assets.
What we deliver
Our substation services may include:
-
- Greenfield and brownfield substation construction, upgrades and asset renewal.
- High-voltage electrical installation, including transformers and circuit breakers up to 500 kV.
- Installation of primary plant, including current and voltage transformers, synchronous condensers and fault-current-limiting devices such as REFCL.
- Reactive power and network stability solutions, including static VAr compensators, capacitors and reactors.
- Connection infrastructure for gas, hydro, wind and solar generation, as well as battery energy storage systems.
- Primary plant and high-voltage testing, including transformer, circuit breaker, earthing, cable, insulation resistance and primary injection testing.
- Protection and control systems, including panel manufacturing support, relay testing, functional testing and protection scheme cutovers.
- Secondary and auxiliary systems, including DC battery and charger systems up to 250 V DC.
- SCADA, remote terminal unit and communications interface integration.
- Factory and site acceptance testing, commissioning management and system energisation support.
- Inspection and test planning, outage coordination and customer liaison.
- Operational maintenance, defect rectification and lifecycle support for high-voltage assets.

More about Substations
Substations are complex, high-risk environments where safety, reliability and careful coordination are essential. Customers need to manage ageing infrastructure, network upgrades, new connections, protection systems and operational constraints, often while working within live or brownfield environments where outages, testing and commissioning activities must be carefully planned.
Our substation services help customers safely deliver greenfield and brownfield projects, renew and upgrade critical assets, and maintain reliable network performance. We provide expertise across construction, testing, commissioning, protection and control systems, and energisation, ensuring work is planned around operational requirements and high-voltage safety. Through disciplined project delivery, quality assurance and comprehensive completion documentation, we help customers reduce delivery risk, improve asset performance and reliability, and support the long-term operation and future development of their electricity networks.
Substation work requires careful preparation before field work begins.
We consider safety, access, outage windows, switching requirements, protection systems, commissioning activities, customer approvals, quality requirements and documentation.
Our teams work with customers to understand the operating environment and plan work that can be delivered safely and with suitable control over technical and operational risks.
