In 2012, after more than a decade working across renewable energy commissioning, protection relay engineering, and SCADA integration in Australia, North America, and the UK, Marcus Webb saw a recurring problem: individual engineering disciplines were technically correct, but gaps between their scopes were causing project delays and failed energisation.
Grid Engineering Group was founded in Melbourne to solve this coordination gap by bringing commissioning, protection, SCADA integration, and HV field engineering together under one accountable team. Our engineers work from shared assumptions, review each other’s outputs, and take responsibility for the interfaces between disciplines as well as the individual engineering scopes.
The engineering that prevents a commissioning failure costs less than the first day of a delayed COD. We build the former to prevent the latter.
Grid Engineering Group is a multi-discipline engineering group specialising in the delivery layer of utility-scale renewable energy projects, taking projects from completed design through commissioning, testing, energisation, and final acceptance. We are not a design firm. We focus on the delivery stage, taking plants through factory and site acceptance testing, protection relay commissioning, SCADA integration, energisation, and performance testing until they are operating within registered parameters and all technical obligations are satisfied.
FAT, SAT, energisation, and performance testing for solar, wind, BESS, and hybrid projects across the NEM, US ISOs, and National Grid ESO territory.
Relay selection, settings calculation, coordination studies, and commissioning for generating plants, substations, and utility networks.
SCADA design, NSP interface submission, and integration testing for AEMO, ERCOT, PJM, and National Grid ESO telemetry requirements.
Specialist protection, SCADA, commissioning, and HV field engineers deployed under EPC project delivery frameworks.
Secondary injection relay testing, insulation resistance testing, power quality measurement, and energisation support.
Protection system modernisation, digital substation engineering, SCADA replacement, and IEC 61850 implementation.
IBR integration studies, BESS co-location engineering, microgrid formation, and large load integration.
Performance monitoring, root cause analysis, protection relay maintenance programs, and modification engineering.
AMI integration, EMS engineering, OT cybersecurity, and digital twin development for utilities and large energy users.
Grid Engineering Group’s primary office is in Melbourne, Australia. We operate across Australia’s National Electricity Market (NEM) and South West Interconnected System (SWIS), across US ISOs under FERC and NERC jurisdiction, and in the United Kingdom under National Grid ESO and distribution network operator frameworks.
Marcus Webb founded Grid Engineering Group in Melbourne in 2012 after more than a decade of commissioning, protection relay engineering, and SCADA integration across Australia, North America, and the UK.Before founding the group, he held senior engineering roles at Aurecon and GHD, focusing on the coordination gaps between engineering disciplines. He has led commissioning and protection engineering for projects ranging from 10MW community solar installations to 500MW utility-scale renewable energy projects, with experience across AEMO, NERC PRC, and UK Grid Code technical requirements.
Grid Engineering Group handles project delivery. Our sister firm, American Power Engineers(americanpowerengineers.com) provides the grid connection advisory, Generator Performance Standards compliance, NERC compliance management, and renewable energy technical due diligence that sits upstream of our delivery work. Developers working with both firms receive coordinated engineering support from the first AEMO connection enquiry through to long-term asset performance management.
The two firms are independent businesses that coordinate on technical interfaces. A developer may engage either firm independently or both firms simultaneously — the technical coordination between the two teams is a feature of the relationship, not a contractual arrangement that requires the developer to manage.
