About Us
EPEC Group is a nationally recognised high-voltage engineering and EPC partner, providing HV power engineering, EPC (for substations, lines and BESS BoP), testing and compliance services, along with market modelling, SCADA and Hardware-in-the-Loop capability.
Since being founded in ****, EPEC has grown rapidly to become a trusted delivery partner on some of Australia's most complex renewable energy projects, from 400 MW solar farms and 200 MW battery storage systems to 330 kV substations delivered for international developers entering the Australian market for the first time.
Founded by specialists in power system engineering, project delivery and generator compliance, our mission is to simplify the grid connection process and remove the uncertainty that costs projects time and money.
We manage connections to the National Electricity Market (NEM) through end-to-end solutions, from pre-enquiry through to connection, registration, testing, compliance and commercial operations.
What sets EPEC apart is that everything is delivered in-house: power system modelling, EPC construction, SCADA, commissioning and compliance testing, all under one roof and one point of accountability.
