Siemens US manufacturing expansion is accelerating in direct response to demand that company executives describe as unprecedented. The company announced $165 million in new investments across four facilities in North and South Carolina, targeting the electrical infrastructure backbone that AI data centers, industrial automation, and grid modernization require.
The announcement, dated March 20, 2026, is part of a broader commitment. Siemens has invested nearly $700 million in U.S. manufacturing operations over recent years. The Carolinas expansion represents the latest and most concentrated deployment of that capital, targeting facilities specifically positioned to serve the data center buildout underway across the Southeast and mid-Atlantic.
Four Facilities, One Strategic Focus: AI Data Center Infrastructure
The expansion spans two states and four distinct production sites, each focused on a specific product category within Siemens’ electrical infrastructure portfolio:
Raleigh, North Carolina: A new 131,000-square-foot facility will add 100 jobs by year-end and assemble Siemens’ integrated power delivery solutions, prefabricated systems that reduce on-site electrical installation time for data centers significantly.
Wendell, North Carolina: A new 101,000-square-foot site will add 50 new roles and localize production of medium voltage protection and automation devices. The Wendell facility is also Siemens’ Electrification and Automation U.S. headquarters, and an expansion of switchgear production there will create more than 200 additional jobs by 2028.
Spartanburg, South Carolina: A new 120,000-square-foot facility will produce lighting panels and, together with the Roebuck expansion, bring 150 new jobs to Spartanburg County.
Roebuck, South Carolina: A 22,000-square-foot expansion adds new paint, epoxy, and plating lines to increase busway production capacity. Busway systems distribute power from transformers throughout data center facilities.
“Artificial intelligence is rapidly becoming core economic infrastructure. By expanding our manufacturing capacity in the United States, Siemens is helping build the backbone that will enable the next wave of industrial AI.”
Roland Busch, President and CEO, Siemens AG
Siemens US Manufacturing Expansion: The Data Center Connection
Siemens executives confirmed that the company is experiencing record levels of data center-related electrical equipment orders. That demand signal is what makes these facility investments economically justified rather than speculative. Each hyperscale AI training facility requires substantial electrical infrastructure: transformers, switchgear, busway distribution, medium voltage protection systems, and power delivery solutions at a scale that was uncommon outside utility substations just a few years ago.
The Carolinas geography is not accidental. The region has emerged as a significant data center corridor, with favorable power rates, land availability, and proximity to fiber infrastructure. Siemens’ expanded manufacturing footprint positions the company to reduce lead times for customers building facilities in the region while also serving broader U.S. demand from a domestic production base.
“These investments expand our ability to deliver the electrical backbone that powers the AI economy.”
Ruth Gratzke, President, Siemens Smart Infrastructure U.S.
Siemens Carolinas Expansion: Facility and Job Summary

| Spartanburg, SC | 120,000 sq ft (new) | Lighting panels | 150 (shared with Roebuck) |
| Roebuck, SC | 22,000 sq ft (expansion) | Busway systems (new paint, epoxy, plating lines) | Included in Spartanburg County total |
Why This Investment Matters Beyond Siemens
The Siemens Carolinas expansion sits at the intersection of two converging industrial trends covered extensively on IndustrialSage: the surge in electrical infrastructure demand driven by AI, and the broader reshoring of industrial manufacturing capacity to the United States.
For plant managers and procurement teams in the industrial sector, the practical implication is that domestic availability of critical electrical components may improve as Siemens and competitors expand U.S. production. That matters for any organization facing the extended lead times currently affecting switchgear, medium voltage equipment, and power distribution systems. Notably, this investment comes alongside reporting that U.S. power transformer lead times now average 128 weeks, a dynamic covered in IndustrialSage’s companion article on the grid equipment shortage.
IndustrialSage tracks major U.S. manufacturing investments through the US Manufacturing Investment Tracker. The Siemens Carolinas expansion is part of a broader wave of electrical infrastructure investment documented in the tracker.

Frequently Asked Questions: Siemens US Manufacturing Expansion
How much is Siemens investing in U.S. manufacturing?
Siemens announced $165 million in new investments across four facilities in North and South Carolina in March 2026. This is part of nearly $700 million the company has committed to U.S. manufacturing operations over recent years. The $165 million Carolinas investment specifically targets electrical equipment production for AI data centers and grid modernization.
Where are the new Siemens facilities located?
The four facilities are in Raleigh, NC (131,000 sq ft, new), Wendell, NC (101,000 sq ft, new), Spartanburg, SC (120,000 sq ft, new), and Roebuck, SC (22,000 sq ft expansion). The Wendell facility also serves as Siemens’ Electrification and Automation U.S. headquarters.
How many jobs will the Siemens expansion create?
The expansion creates 350+ new positions across the four facilities, with 200 additional jobs expected at the Wendell facility by 2028 as switchgear production scales. Spartanburg County will receive 150 jobs shared across the Spartanburg and Roebuck sites.
What products will the new Siemens facilities manufacture?
Products include integrated power delivery solutions for data centers (Raleigh), medium voltage protection and automation devices plus switchgear (Wendell), lighting panels (Spartanburg), and busway power distribution systems (Roebuck). All product categories serve the electrical infrastructure requirements of AI data centers and industrial electrification.
Why is Siemens expanding in the Carolinas specifically?
The Carolinas have emerged as a significant data center corridor with favorable power rates, land availability, and fiber infrastructure. Siemens’ expanded manufacturing footprint in the region positions the company to reduce lead times for customers building facilities nearby while also serving broader U.S. demand from a domestic production base.
How does the Siemens expansion relate to the broader U.S. electrical equipment shortage?
The same AI data center demand driving record transformer lead times is driving Siemens’ capacity expansion. Siemens reported record levels of data center-related electrical equipment orders as the justification for the investment. The expansion will add U.S.-based production of switchgear, medium voltage equipment, and power distribution systems, categories currently experiencing extended lead times industry-wide.
