What TOR Engineering does
TOR Engineering Corporation is a privately held electrical engineering consulting firm headquartered in Phoenix, Arizona, founded in 1985 by the late Thomas O. Radnoti. The company delivers professional engineering services to electric utilities, municipalities, and government agencies, organized across four service lines: Electrical Substations, Electrical Transmission, Electrical Distribution, and Automation & Power System Studies. Its technical scope spans service voltage through 500kV, covering greenfield and brownfield substation design, transmission line engineering (69kV–500kV), overhead and underground distribution (including smart-grid and wildfire-mitigation work), and supporting power-systems studies such as transient analysis, interconnection studies, protection coordination, short-circuit, grounding, arc-flash, and SCADA/relay automation. Capabilities extend across Air-Insulated Switchgear (AIS) and Gas-Insulated Switchgear (GIS) architectures, with complementary offerings in sag-tension and vibration analysis for transmission conductors.
The firm's business model is professional services, project-based, with custom-quoted engagements rather than published pricing. It reaches customers through direct enterprise sales targeting major utilities (APS, SRP, NV Energy, TEP, MidAmerican, Pacificorp, Imperial Irrigation District, Berkshire Hathaway Energy subsidiaries, and various Arizona cooperatives) and government entities (City of Mesa, Phoenix Sky Harbor International Airport, Valley Metro, Boulder City). Delivery is anchored by approximately 80 professionals including Professional Engineers licensed across multiple states, with senior leadership continuity averaging multiple decades (Darla Jackson, Chief of Finance, since 1990; Mario Acevedo, President, since 2004; Gerardo Brignone, VP T&D, since approximately 2006; Nenad Metlic, VP Substation Operations, since 2007; Steve Nappa, VP Business Development, since 2014). Strategic partnerships with Quanta Infrastructure Solutions Group and WSP USA extend its delivery capacity for larger multi-discipline scopes across North America.
TOR is founder-influenced and privately held, with no disclosed institutional investors, private equity sponsors, or parent entity. The company maintains recruiting pipelines through Indeed, Handshake, Pipeline AZ, and Arizona State University for ongoing engineering talent acquisition. Geographic focus is the Southwestern United States with engagement extensions into the broader Western and Midwestern US utility territories via its Berkshire Hathaway Energy relationships. No revenue, funding rounds, M&A activity, or public-market transactions are disclosed in available data.
