Western Electrical Services

What Western Electrical Services does

CBS Field Services is a NETA Accredited Company providing on-site electrical testing, maintenance, commissioning, and power engineering services for industrial, utility, healthcare, and energy customers across the United States and Canada. The company was founded in 2001 as part of Group CBS and operates from 14+ office locations spanning Phoenix (headquarters), Charlotte, Denton, Des Moines, Los Angeles, Lakeland, Nashville, Quincy, Raleigh, Sacramento, Salt Lake City, Seattle, Calgary, and Vancouver. Its core service portfolio includes electrical testing and maintenance (power monitoring, circuit breaker timing), electrical acceptance testing and commissioning, arc flash studies and power engineering, and thermographic/infrared surveys, complemented by specialized offerings in photovoltaic array testing, SF6 equipment maintenance, medium-voltage cable testing, DC battery system maintenance, and circuit breaker modernization delivered through Group CBS affiliates.

The business model is a professional services / field services model rather than a software or product platform. Revenue is generated through quote-based, multi-year enterprise contracts with no publicly disclosed pricing. Services are delivered by NETA-certified technicians deployed on-site to customer facilities, with 24/7 emergency response and disaster relief capabilities supported by mobile repair workshops. The go-to-market motion is enterprise field sales, with direct customer engagement for quotation and project scoping. Named customers include MultiCare Tacoma General Hospital (emergency power restoration) and BP Whiting Oil Refinery (transformer testing). The company holds no patents, offers no API or SDK, and has no disclosed software platform.

Operationally, CBS Field Services benefits from its integration within the Group CBS conglomerate, which includes Circuit Breaker Sales (North America's largest inventory of overcurrent protective devices), Vacuum Interrupters (SF6 services), and Advanced Electrical & Motor Controls (retrofit/upgrade services). This enables a field-to-shop turnkey value proposition where field diagnostics feed into equipment repair and replacement revenue at sibling entities. The company is privately held with no external institutional investment disclosed, and is led by President Matthew Wallace (appointed January 2024) and Vice President of Business Development Mose Ramieh. The company does not disclose revenue, headcount, or financial statements in available materials.
