What SAI Advanced Power Solutions does

SAI Advanced Power Solutions is a privately held U.S. manufacturer of low and medium voltage switchgear, power distribution units, and EV charging power platforms, headquartered in Franklin Park, Illinois with additional operations in St. Charles, Carol Stream, and (historically) Elmhurst. The company operates with 101–250 employees and traces its corporate lineage to Switchboard Apparatus Co., founded in Chicago in 1907; the modern SAI entity was formed in 2010 when Switchboard Apparatus combined with the ASCO Custom Engineered Services business acquired from Emerson Network Power.

The company's product portfolio centers on UL1558 low voltage switchgear (up to 10,000A, 200kAIC), UL891 switchboards, the SlimVAC and SlimVAC AR medium voltage switchgear lines (claimed as the industry's smallest-footprint ANSI metal-clad designs), custom medium voltage switchgear up to 4000A / 63kA, the Profusion integrated PDU platform with BCMM branch monitoring, the EVention EV charging power distribution platform (BABA-compliant and multi-source capable), and Modular Power Skid solutions. Manufacturing is 100% vertically integrated across more than 150,000 sq. ft. of production and warehouse space, with a new 3X-capacity production center announced in 2024.

SAI sells primarily through a direct enterprise field-sales motion, organized into five business units — Mission Critical (data centers, healthcare, telecom), OEM, Commercial/Industrial/Government, Emerging Markets (renewable integration, EV charging, hydrogen, storage, smart grid), and Parts and Service — and serves customers including Fortune 500 companies, government facilities, and international OEMs. Revenue is generated through hardware sales of switchgear and power distribution equipment and through professional services covering startup/commissioning, training, engineering, field retrofit, and preventative maintenance, with pricing conducted on a quote-based proposal model rather than published list pricing.

Direct peers

• Vertiv Holdings: Vertiv provides critical digital infrastructure including power distribution units (PDUs), switchgear, UPS, and monitoring solutions for data centers and communication networks. With the Profusion PDU platform, SAI competes most directly with Vertiv in the data center PDU and busway category.
• ASCO Power Technologies: ASCO Power Technologies (now part of Emerson/Vertiv) designs and manufactures automatic transfer switches, power control systems, and custom engineered power solutions. SAI's modern entity was formed through the 2010 acquisition of the Emerson Network Power ASCO Custom Engineered Services unit, making ASCO a historical predecessor and current peer in custom power solutions.
• Powell Industries: Powell Industries is a publicly traded manufacturer of custom-engineered metal-clad switchgear, metal-enclosed switchgear, and electrical houses for utilities, industrial, and commercial markets. As a focused switchgear specialist with similar custom-engineering capabilities, Powell is one of SAI's closest direct peers despite its larger scale.

Broad incumbents

• ABB: ABB is a global leader in electrification products including low- and medium-voltage switchgear, motor control, and protection systems. ABB is both a key breaker supplier to SAI and a direct competitor for ANSI metal-clad MV and LV switchgear in data center, utility, and industrial applications.
• Eaton: Eaton is a global power management leader with a major Electrical Americas segment that manufactures switchgear, switchboards, and power distribution equipment. SAI competes directly with Eaton on UL1558 low-voltage switchgear, UL891 switchboards, and custom power distribution solutions, though Eaton operates at vastly greater scale with a full-product power management portfolio.
• Hubbell: Hubbell Incorporated is a diversified electrical products manufacturer providing utility solutions, lighting, and electrical products including commercial and industrial switchgear and power distribution components. Hubbell competes with SAI across multiple customer verticals while operating a much broader electrical products portfolio.
• Siemens: Siemens Smart Infrastructure division provides LV/MV switchgear, switchboards, and integrated power distribution. SAI partners with Siemens for breakers while also competing for custom switchgear builds across data center, OEM, and government segments.
• Schneider Electric: Schneider Electric is one of the largest global electrical equipment manufacturers, offering a comprehensive portfolio of low- and medium-voltage switchgear, PDUs, and power distribution solutions. As one of SAI's named breaker partners, Schneider is both a component supplier and a direct competitor in mission-critical power distribution.
• GE Industrial Solutions (ABB): GE's industrial solutions business (now owned by ABB) historically produced switchgear, switchboards, and motor control centers for industrial and commercial customers. It represents a major incumbent competitor to SAI in LV/MV switchgear and power distribution, particularly for legacy GE-spec commercial installations.

Regional players

• Myers Emergency Power Services: Myers is an emergency power services provider specializing in transfer switches, switchgear, and power generation equipment servicing the eastern United States. As a regional custom switchgear and emergency power services company, Myers shares SAI's custom-engineering model and target verticals (healthcare, data centers, government) but operates in a different US geography.
