What Sparkstone does

Sparkstone Electrical Group (SEG) is a U.S. manufacturer of custom-engineered electrical power distribution and control equipment, headquartered in Addison, Illinois, and operating five manufacturing facilities across Illinois, Colorado, Michigan, and Texas. The company was formed in 2023 by unifying four legacy brands — Chicago Switchboard (founded 1936), Park (founded 1945), IER (25+ years operating), and CES Industrial (founded 1998) — into a single national platform covering low-voltage equipment (UL 891 switchboards, UL 1558 switchgear, UL 67 panelboards, 800 VAC solar switchboards), medium-voltage equipment (metal-clad and metal-enclosed switchgear up to 38 kV, utility metering cabinets, secondary bus enclosures), and UL 508A/UL 698-certified industrial control panels. SEG maintains a vendor-agnostic architecture integrating breakers, metering, and relays from ABB, Eaton, GE, Schneider Electric, and Siemens, and supports legacy Square D and Cutler-Hammer footprints for retrofit work.

SEG sells exclusively on a project-by-project, quote-driven basis with no public pricing and no e-commerce channel. The go-to-market combines a direct enterprise field sales team with a network of 13 independent manufacturer sales representative firms covering all 50 U.S. states, generating revenue through one-time equipment sales supplemented by engineering services (custom design, arc flash mitigation, protection and control), project management (submittal packages, factory acceptance testing, commissioning), and a dedicated disaster recovery and emergency replacement service line. Target customers include data center OEMs (cited average project value of $20 million), utilities and municipal infrastructure operators, industrial manufacturers, renewable energy developers, food and beverage processors, commercial construction firms, and retail operators. SEG is privately held, led by President Ken Alloway and a senior team drawn from Square D, GE, ABB, Eaton, Schneider Electric, S&C Electric, SATEC, and CE Power.
