What Associated Power Solutions does

Associated Power Solutions (APS) is a privately held electrical testing and inspection services company headquartered in Concord, California, founded circa 2000 and operating for over 25 years. The firm delivers third-party testing services for power systems at industrial and commercial facilities, with a service territory concentrated in Northern California and the San Francisco Bay Area and a soft extension into parts of Southern California. Its target end markets span power plants, refineries, medium- and high-voltage substations, low/medium/high-voltage switchgear, and other industrial and commercial facilities.

APS operates three core service lines: (1) Maintenance Testing, covering circuit breaker time-travel analysis, meter and relay testing, transformer power factor and oil analysis, and NERC compliance support; (2) Acceptance/Commissioning Testing, which validates new electrical installations across grounding systems, battery systems, circuit breakers and switchgear (including high-voltage SF6 breakers and circuit switchers), protective relays, power transformers, cables, rotating machinery, power factor, and instrument transformers; and (3) Additional Services, including shop testing of breakers, relay calibration, arc flash data collection, training, and relay upgrade solutions. Testing execution relies on physical test equipment and field-technician expertise; the company holds ISNetworld contractor certification and emphasizes a safety culture of daily briefings and weekly toolbox discussions.

The business model is project-based professional services: engagements are quote-based and tailored to client requirements, sold through a sales-led, direct-engagement GTM with field-based technicians delivering on-site service. Marketing is minimal, centered on the company website (aps-power.com) as the primary digital presence. Revenue is generated entirely from electrical testing services; pricing is not publicly disclosed, and there is no software, subscription, or recurring-revenue component in the offering.
