EPEC Group

What EPEC Group does

EPEC Group is a privately held Australian high-voltage engineering and EPC (Engineering, Procurement, and Construction) contractor founded in 2019, headquartered in South Brisbane, Queensland. The company specialises in renewable energy grid connections across Australia's National Electricity Market (NEM), Western Australian Market (WEM), Northern Territory, New Zealand, and Southeast Asia. EPEC delivers an integrated suite of eight interconnected service areas — power system engineering (including grid studies, GPS development, and the R0/R1 connection pathway), EPC for substations (33kV to 330kV with 500kV readiness) and BESS infrastructure, high-voltage substation commissioning, SCADA and control systems, hardware-in-the-loop (HIL) testing, electricity market and network modelling, and generator commissioning with NER Chapter 5 compliance — under a single point of accountability to eliminate handover failures between design, construction, and compliance stages. The company maintains two offices (Brisbane headquarters and Melbourne) and operates through wholly owned subsidiaries EPEC Projects Pty Ltd and EPEC Technologies Pty Ltd.

EPEC's technology stack integrates industry-standard power system simulation tools — PLEXOS for market modelling, PSS®E and PSCAD for grid studies, PowerFactory for power quality and harmonics, and OPAL-RT real-time simulators for HIL testing — with the Ignition SCADA platform (Gold Certified System Integrator) supporting DNP3, Modbus, IEC 61850, and OPC-UA protocols. The proprietary HIL Testing Platform, launched in February 2025, enables pre-commissioning validation of control hardware against real-time simulated electrical networks before site mobilisation. The EPEC Technologies division functions as a specialist innovation arm for multi-OEM integration, OEM onboarding, and university collaboration. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, is FSC certified, and is a Clean Energy Council member.

EPEC generates revenue through a mix of project-based EPC contracts (fixed-price or cost-plus), professional services for engineering studies and compliance testing, and subscription-based electricity market modelling services with quarterly refresh. Its client base spans tier-one renewable energy developers, asset owners, OEMs, and EPC contractors, with named customers including Neoen, ACEN, Origin Energy, Enel Green Power, BP, Samsung C&T, BayWa r.e., Lendlease, Doosan, Global Power Generation, PCL, and the University of Queensland. The company sells exclusively through direct enterprise sales and project tenders, targeting the full project lifecycle from feasibility through commissioning and ongoing operational compliance.

Core offering

EPEC Group delivers vertically integrated high-voltage engineering, EPC construction, and compliance services that connect utility-scale renewable energy projects (solar, wind, and battery energy storage systems) to Australia's National Electricity Market. Services span power system studies and connection applications, substation design and construction, SCADA and control systems using the Ignition platform, hardware-in-the-loop pre-commissioning testing, market and network modelling, and NER Chapter 5 generator commissioning and compliance testing, all delivered under a single point of accountability by an in-house multidisciplinary team.

Product overview

EPEC Group offers a unified platform of grid connection and renewable energy engineering services rather than discrete software products. The core offering integrates eight interconnected service areas: Power System Engineering (grid studies, GPS, R0/R1 connection pathway), Engineering Design Procurement & Construction (EPC for substations and BESS), High Voltage Substation Commissioning, SCADA & Control Systems (Ignition-based monitoring and control), Hardware-in-the-Loop (HIL) Testing, Electricity Market & Network Modelling (PLEXOS/PSS/E-based forecasting), Generator Commissioning & NER Chapter 5 Compliance, and EPEC Technologies (innovation division). These services are delivered in-house under single accountability, with EPEC Technologies providing specialized innovation and integration capability that supports the broader company across engineering, projects and operations.
