Detailed Design
Full electrical, civil, structural and SCADA engineering performed entirely by in-house teams to IFC standard.
Procurement
Global sourcing of major equipment with OEM relationship management and Factory Acceptance Testing (FAT) oversight.
Construction & Commissioning
Site execution, R2 testing and operational handover with a Tier 1 safety record and full compliance focus.
Full-Lifecycle EPC Delivery
EPEC delivers end-to-end Engineering, Procurement, and Construction (EPC) services for renewable energy infrastructure across Australia and Southeast Asia. Our in-house capability spans every project phase — from early concept through to commercial operation — providing a single point of accountability that reduces risk and keeps delivery on schedule.
Our substation portfolio spans 33 kV to 330 kV, with proven experience across solar farms, battery energy storage systems (BESS), hybrid renewable plants, and standalone high-voltage substations. Every project is engineered to the highest safety and compliance standards under ISO 9001, ISO 14001 and ISO 45001 certification.
With electrical contractor licences across QLD, NSW, SA, WA, VIC and ACT, EPEC has the national reach and in-house expertise to self-perform critical works — from switchyard construction to SCADA integration and final grid energisation.
Hardware-in-the-Loop (HIL) Testing
Validates control systems against real-time simulation models before equipment reaches site, significantly reducing commissioning risk, rework and schedule overruns.
Electricity Market & Network Modelling
Integrated electricity market and network simulations to support confident investment and operational decisions — including dispatch modelling, stability analysis and ongoing compliance monitoring across the NEM, WEM and NT.
Verification from Concept to Commercial Operation
EPEC's commissioning and testing services ensure every asset performs to specification before and after energisation — covering HV substations, generators and SCADA systems.
High Voltage Substation Commissioning
A structured engineering process that verifies the integrity, functionality, and compliance of high-voltage infrastructure prior to energisation — from protection testing to switchyard commissioning.
SCADA & Control Systems
Remote monitoring and control solutions for substations and renewable energy assets using the Ignition platform — EPEC is an Inductive Automation Gold System Integrator Partner.
Generator Commissioning
R2 commissioning and NER Chapter 5 compliance support for all generator types — including inverter-based resources (solar, BESS, wind) and synchronous generation. EPEC manages the full compliance testing program through to final AEMO registration.
