Why it matters now: For years, North American manufacturers and system integrators faced a bottleneck: accessing Siemens SIMATIC PLCs and engineered automation systems meant navigating a limited network of specialized distributors. With the launch of City Electric Supply's Industrial Automation Solutions division, that equation has fundamentally changed — 750 branch locations now serve as direct gateways to Siemens Digital Industries' full control portfolio and an ecosystem of complementary hardware and software from Wieland, Rittal, Eplan, Lutze, and Grace Technologies.
Inside the CES–Siemens Partnership
On July 22, 2026, Dallas-headquartered City Electric Supply (CES) formally announced its Industrial Automation Solutions (IAS) division, built around a strategic partnership with Siemens Digital Industries (DI). The new division provides professionally engineered industrial automation and control systems — with Siemens SIMATIC PLCs at the core — to customers across CES's sprawling North American branch network.
"IAS allows us to expand the expertise, technology, and support we provide to our customers through professionally engineered industrial automation and control systems," said Rich Antonaros, vice president of Centralized Branch Services at CES. The initiative is backed by a growing team of in-house automation specialists who support branch-level consultations, system design, and ongoing optimization.
Analyst Insight: Distribution as Competitive Moat
This partnership represents a calculated move by Siemens DI to close the accessibility gap with competitors who have historically leveraged broader electrical distribution channels in North America. With 750+ CES branches now equipped to specify, sell, and support SIMATIC PLCs — from the S7-1200 series to advanced S7-1500 controllers and ET 200 distributed I/O — Siemens is positioning its automation portfolio for the mid-market manufacturing segment that has long relied on local electrical supply relationships. For CES, IAS transforms the company from a commodity electrical distributor into a value-added automation solutions provider — a margin-rich territory that insulates against price-based competition in traditional electrical wholesale.
The Ecosystem: Beyond the PLC
IAS is not a single-vendor play. CES has curated a partner ecosystem that mirrors the real-world needs of control panel builders and machine OEMs. Alongside Siemens DI, the division offers exclusive access to:
-
Wieland Electric — terminal blocks, interface modules, and safety technology for control cabinets
-
Rittal — industrial enclosures, climate control, and power distribution hardware
-
Eplan — electrical and fluid engineering software for panel design and documentation
-
Lutze Automation — cable management, connectivity, and control solutions
-
Grace Technologies — predictive maintenance devices and permanently installed electrical safety solutions
This multi-vendor alignment means customers can source a fully engineered control system — from the enclosure and PLC to wiring, power distribution, and engineering documentation — through a single channel, reducing procurement complexity and lead-time fragmentation.
One-Line Service Integration: From Power to Control
The IAS division integrates directly with CES's existing One-Line Service, the company's in-house switchgear assembly and distribution arm that designs custom electrical gear packages. While One-Line Service delivers panelboards, switchboards, and motor control centers (MCCs), IAS adds the control layer — SCADA systems, PLC-based automation, and networked I/O — turning what was historically a power-distribution-only relationship into a full-scope electrical-and-controls partnership.
"In extension of CES One-Line Service, IAS will serve as a way to control what we're bringing power to," Antonaros explained, underscoring the strategic logic: CES now supplies both the muscle and the brain of industrial electrical infrastructure.
Market Trends: North American PLC Demand in Context
The timing of the CES–Siemens alliance aligns with robust structural tailwinds. The North American industrial control systems market was valued at approximately USD 47.77 billion in 2025, with PLCs commanding a 30.85% share — the single largest hardware segment. Siemens holds roughly 12% of the global industrial automation market, and its Digital Industries segment reported 12% automation order growth in Q1 FY2026, driven by short-cycle demand and double-digit discrete automation expansion. Reshoring, data center construction, and chronic skilled-labor shortages are accelerating demand for pre-engineered control solutions — precisely the value proposition IAS brings to the table.
What This Means for System Integrators and End Users
For system integrators who build control panels or program PLCs for end customers, the IAS model shortens the path from specification to delivery. Instead of routing orders through specialized automation distributors with limited geographic coverage, integrators can now work with local CES branches — many in secondary and tertiary markets historically underserved by automation-focused distributors.
End users — food and beverage processors, material handling operations, water/wastewater facilities, and discrete manufacturers — gain on-ramp access to Siemens' Totally Integrated Automation (TIA) Portal ecosystem without needing pre-existing relationships with a dedicated Siemens solution partner. The IAS specialist team provides the engineering bridge, handling system architecture, component selection, and design validation.
Key Benefits for Industrial Buyers
-
Geographic reach: 750+ CES branches across the U.S. and Canada mean same-region support for most industrial facilities.
-
Vendor consolidation: One purchase order can cover enclosure (Rittal), PLC (Siemens), wiring (Wieland/Lutze), engineering software (Eplan), and safety devices (Grace).
-
Engineering support: IAS in-house specialists handle system design — a critical advantage for end users who lack dedicated controls engineering staff.
-
Faster turnaround: Integration with One-Line Service enables coordinated delivery of power-distribution gear and control systems from a single supplier.
-
TIA Portal compatibility: Full alignment with Siemens' engineering framework ensures seamless programming, commissioning, and lifecycle management.
The Bigger Picture: Democratizing Access to Advanced Automation
The CES–Siemens partnership signals a broader industry shift: the line between electrical wholesale and industrial automation distribution is blurring. As PLCs, VFDs, and networked I/O become standard components in even modest industrial projects, electrical distributors with the scale and ambition to invest in engineering capabilities are moving up the value chain.
For Siemens, the CES channel opens a conduit into thousands of manufacturing facilities that may have previously defaulted to competitive PLC platforms simply because those brands were available through their incumbent electrical supplier. For the North American manufacturing base — much of it comprised of small-to-midsize enterprises — broader access to Siemens automation technology lowers the barrier to adopting Industry 4.0 practices, from condition monitoring to digital-twin-based commissioning.
Frequently Asked Questions
Q: What Siemens PLC products are available through CES IAS?
The IAS division provides access to the full Siemens SIMATIC portfolio, including S7-1200 and S7-1500 controllers, ET 200 distributed I/O, HMI panels, SINAMICS drives, and TIA Portal engineering software. Specific availability may vary by branch and application requirements — IAS specialists assist with product selection.
Q: Is IAS limited to Siemens products?
No. While Siemens DI serves as the flagship automation partner, IAS distributes products from Wieland, Rittal, Eplan, Lutze, and Grace Technologies, offering a multi-vendor control-panel ecosystem through a single channel.
Q: Does CES provide programming and commissioning services?
IAS focuses on engineered system design, component specification, and supply. For complex programming and commissioning, CES specialists can coordinate with Siemens-certified solution partners and system integrators within their network.
Q: How does IAS differ from traditional automation distributors?
The key differentiator is scale and accessibility: 750+ branches versus the typically limited footprint of specialized automation distributors. CES also combines power-distribution expertise (via One-Line Service) with control-system design, offering an integrated electrical-and-automation solution.
Q: When did the IAS division launch?
The Industrial Automation Solutions division was formally announced on July 22, 2026, though CES had been building the specialist team and supplier partnerships in the months prior.
