Why it matters now: The North American PLC and industrial controls supply chain is undergoing its most significant geographic realignment in decades. On August 7, 2026, Siemens threw down a $200-million-plus gauntlet — two new U.S. factories in Pendergrass, Georgia, and Grand Prairie, Texas — aimed squarely at closing the gap with Rockwell Automation, which commands an estimated 50–60% of the North American discrete automation market. With 1,500 new American jobs and production lines designed for AI-era electrical infrastructure, the move signals that the battle for the factory floor is no longer just about technology — it is about who builds it, and where.
Analyst Insight — Supply Chain Sovereignty: This investment is not merely capacity expansion; it represents a structural hedge. For two decades, Siemens has served North American customers largely from European and Asian production hubs. By localizing manufacturing for SIMATIC PLC lines, medium-voltage switchgear, and busway systems on U.S. soil, Siemens reduces exposure to transatlantic logistics bottlenecks, tariff volatility, and geopolitical friction — directly mirroring the reshoring playbook that helped Rockwell build its North American moat.
Inside the Numbers: Two Facilities, One Strategy
The Pendergrass, Georgia, and Grand Prairie, Texas, sites are purpose-built for AI-driven electrical demand. The Grand Prairie facility will begin hiring in late 2026, with Pendergrass coming online in 2027. Combined, the two sites will generate more than 1,500 fabrication, assembly, testing, materials-handling, and engineering roles. Both plants will be 100% electrified from day one, with the Georgia facility featuring electric paint lines and advanced energy management systems — a window into Siemens' own digital-twin-led factory design methodology.

The Rockwell Question: Can Siemens Crack the North American PLC Stronghold?
Globally, Siemens commands roughly 30–33% of the PLC market, making it the largest player worldwide. But geography tells a different story. In North America, Rockwell Automation's Allen-Bradley brand holds over 50% of PLC market share, with some estimates placing its discrete-automation dominance closer to 60% when drives, motion control, and safety controllers are factored in. Rockwell derives approximately 63% of its $8.34 billion FY2025 revenue from North America alone.
Siemens' new U.S. factories will localize production of medium-voltage protection and automation devices — products that sit adjacent to SIMATIC PLCs in the controls architecture. Combined with the company's Xcelerator digital ecosystem, the physical proximity to North American customers could reduce integration costs that analysts estimate run 20–30% higher for Siemens outside Europe due to thinner support networks.
Market Trend — AI Data Centers as Automation Catalyst: The global PLC market reached approximately $13.45 billion in 2026, with projections of $21.83 billion by 2034 (CAGR 6.20%). But the hidden accelerator is AI data center construction — each hyperscale facility requires extensive power distribution, cooling automation, and backup control systems, all of which depend on PLCs and associated switchgear. Siemens is betting that controlling the electrical backbone of the AI buildout gives it a natural entry point for the controls layer.
Beyond PLCs: Digital Twins, EDA, and Industrial AI
The $200-million commitment extends beyond physical hardware. Siemens is channeling resources into digital twin platforms that allow manufacturers to simulate entire production lines before breaking ground, electronic design automation (EDA) tools for chip and board-level design, and industrial AI capabilities — including generative AI applications — that bring real-time optimization to factory floors.
At Hannover Messe 2026, Siemens unveiled expansions to its Industrial Edge ecosystem, featuring IEC 62443-4-2-certified security for critical infrastructure and air-gapped operation capabilities. This IT/OT convergence play directly addresses the cybersecurity concerns that have slowed digital transformation in process industries, and positions Siemens to offer an end-to-end proposition — from electrical infrastructure through PLC hardware to edge-based AI analytics.
FAQ: What This Means for Automation Professionals
Q: Will SIMATIC PLC lead times improve in North America?
While the new facilities focus primarily on electrical infrastructure, localized production of adjacent automation components — combined with Siemens' broader $1 billion U.S. investment — is expected to streamline the entire North American supply chain, potentially reducing lead times for integrated systems.
Q: How does this affect Rockwell Automation's position?
Rockwell's North American integrator network remains the deepest in the industry. However, Siemens' Xcelerator platform and aggressive localization could erode the integration-cost premium that has historically insulated Rockwell. Jefferies downgraded Rockwell to Hold in March 2026, citing structural risks from Siemens and Schneider Electric's parallel AI and digital pushes.
Q: Are the new factories producing PLCs directly?
The Grand Prairie and Pendergrass sites are centered on electrical infrastructure — switchgear, busway, and protection devices. However, these components are frequently bundled with SIMATIC controllers in integrated automation solutions. Siemens' existing U.S. manufacturing footprint in Wendell, NC, and other locations already produces automation and electrification products, creating a synergistic network.
Q: What is the broader reshoring significance?
Siemens' $1 billion cumulative U.S. manufacturing investment (announced May 2026) spans industries from power equipment to passenger rail. The August 2026 announcement confirms that industrial automation supply chains are being fundamentally restructured around regional self-sufficiency — a trend that benefits end-users through shorter lead times and localized support.
The Global Context: A Coordinated Expansion
The U.S. investment is not occurring in isolation. In July 2026, Siemens committed €300 million (~$345.8 million) to its German factories to support AI and data center demand. In March 2026, the company invested over $165 million across North and South Carolina, adding 350 jobs for medium-voltage protection and automation device production. The cumulative picture is one of a globally coordinated manufacturing ramp-up, with the U.S. receiving a disproportionate share of new factory investment.
This aligns with broader macro forces: the IIJA and IRA have triggered a capital expenditure boom in U.S. manufacturing, reshoring of critical technology supply chains has become a bipartisan priority, and the AI revolution's insatiable appetite for power infrastructure shows no signs of abating. Siemens is positioning itself not merely as a beneficiary of these trends, but as their infrastructure architect.
Bottom Line for Industrial Buyers: The Siemens-Rockwell competition is entering a new, geographically grounded phase. For end-users evaluating PLC and automation platforms, the calculus now extends beyond feature sets and programming environments to include regional supply assurance, localized support depth, and integration cost parity. The next 18–24 months will reveal whether Siemens' brick-and-mortar bet can translate into meaningful North American market share gains — or whether Rockwell's entrenched integrator ecosystem proves too resilient to dislodge.
