What PSC - Power Systems Consultants does

PSC - Power Systems Consultants (legal entity: PSC Specialists Group Inc.) is a privately held specialist consulting firm founded in 1995 in New Zealand that delivers engineering and strategic advisory services to the electricity sector. The firm operates globally with offices in the United States, Canada, the United Kingdom (including an Edinburgh office opened in March 2025), continental Europe, Australia, New Zealand and Asia, and bills through project-based consulting engagements and multi-year advisory retainers on a professional services model. Co-founder Tony Armstrong remains Global CEO, with Alex Boyd as President & CEO and Ranil De Silva as co-founder.

The company's practice portfolio spans Power Networks (transmission and distribution modeling, HV earthing, lightning protection, power-system protection), Operational Technologies (EMS/DMS upgrades, control-room modernization), Market Systems (energy-market software engineering), HVDC design and deployment, Distributed Energy Resources planning, Strategic Advisory including OT cybersecurity, and Collaborative Services covering Data Analytics (predictive maintenance, renewable forecasting using machine learning) and Subsea Cables. Technical delivery leans on industry-standard power-systems simulation suites — CDEGS, PSCAD/EMTDC, PSSE, DIgSILENT PowerFactory and ETAP — combined with proprietary generator test equipment featuring embedded safety controls, and PSC maintains vendor-neutral positioning as an AspenTech (OSI) Delivery Service Provider and a participant in GE Vernova's GridOS Partner Program.

PSC serves transmission system operators (National Grid, EirGrid, Transpower, AEMO, PJM, NorthernGrid), distribution utilities (Western Power Distribution, SA Power Networks, Network Waitaki, Idaho Power, ATCO Electric), generation companies and renewable developers (Cero Generation, Diamond Transmission Partners, Wheelabrator Technologies, First Energy) and co-delivers with strategy firms such as Deloitte on offshore wind work. The firm is governed by detailed project-management methodology, draws pricing from bespoke engagements rather than disclosed rates, and reinforces its brand through active participation in CIGRE and IEEE (where Technical Director Zia Emin chairs CIGRE Study Committee C4) and through continued sponsorship of the PEET power-engineering scholarship program at the University of Canterbury.
