Direct peers

• Shermco Industries: One of the largest independent NETA-accredited electrical testing, maintenance, and commissioning firms in North America, directly comparable to PST in core services, certification posture, and field-service delivery model.
• RESA Power: Nationally focused NETA electrical testing, commissioning, and field services platform built largely via roll-ups of regional testing firms - directly comparable operating model to PST, with peer-overlap on arc-flash, acceptance, and maintenance testing.
• Electrical Reliability Services (ERS, formerly AZZ Electrical Reliability Group): Major NETA-certified provider of electrical acceptance and maintenance testing, commissioning, and engineering services - closely comparable to PST in scope, accreditation, and customer types.

Broad incumbents

• Integrated Power Services (IPS): PST's parent company and a leading North American provider of electrical, mechanical, and power management services - relevant as the broader incumbent whose Power Management Division now houses PST and against whose scale PST must compete.
• Vertiv: Global power-management and electrical services incumbent serving data centers and critical infrastructure - overlapping with PST on electrical testing, commissioning, and maintenance for high-reliability customers.
• Eaton: Diversified power management manufacturer with a sizable electrical services and field engineering organization - comparable in end-customer overlap (utilities, industrials, public sector) though services are part of a much broader portfolio.
• Schneider Electric: Global energy management and automation incumbent offering field services, electrical testing, and power systems support - comparable in target customers and core electrical services even though services are bundled within a much larger product portfolio.
• ABB: Global electrification and automation company with extensive electrical service, commissioning, and testing capabilities for utility and industrial customers - relevant incumbent comparable to PST on commissioning and lifecycle testing work.

Emerging players

• Doble Engineering: Specialized provider of diagnostic testing instruments and services for electrical power assets - comparable to PST on testing methodology and utility/industrial customer overlap, though more instrument-and-software oriented than pure field service.

Regional players

• High Voltage Power Systems: Independent regional field-service provider of high-voltage electrical testing, commissioning, and maintenance - comparable operating model to PST in core field-service delivery and NETA-style work, but operating in different U.S. regions.
