What Nilsen does

Nilsen is a family-owned Australian electro-technology company founded in 1916 and headquartered in Mulgrave, with operations spanning all major Australian states (Western Australia, South Australia, New South Wales, Victoria, Queensland) and approximately 1,001-5,000 employees. The company delivers full-lifecycle electrical technology services for critical infrastructure projects through three wholly-owned subsidiaries: Nilsen Switchboards (in-house switchboard design, manufacture, and testing), Nilsen Networks (communications and networking services), and Nilsen Engineering Services (engineering and TEGG predictive-maintenance services).

The service portfolio spans electrical contracting (design, installation, commissioning, repair, maintenance), in-house switchboard manufacturing, communications systems, construction project delivery, energy management, EV charging infrastructure, field services, high-voltage (High Energy) solutions including substations and circuit breakers, and exclusive TEGG predictive and preventative maintenance with insurance-backed equipment protection. Technology centres on domain-specialised electrical contracting, award-winning switchboard fabrication with rigorous testing for critical infrastructure, and configurable stadium/architectural LED lighting systems. Revenue is generated through project-based competitive tenders, multi-year construction engagements, and recurring maintenance/TEGG service contracts, with pricing not publicly disclosed and standard 30-day payment terms.

Customers are predominantly large Australian enterprises and government entities, including head contractors Multiplex, Probuild, John Holland, and Brookfield Multiplex, the Australian Department of Defence, state health departments, Royal Adelaide Hospital ($1.8B project), Fiona Stanley Hospital, Optus Stadium, and Edith Cowan University. The go-to-market is enterprise field sales via direct tendering, supported by an industry-validated NECA awards record, case-study-based content marketing, and a 24/7 nationwide response line (1300 NILSEN).
