Siemens AG has announced a €300 million investment to expand its electrical switchgear production in Germany, constructing a new supplier facility in Offenbach and upgrading two existing plants in Frankfurt. Slated to begin construction in July 2026, this expansion aims to satisfy soaring global demand from AI data centers, e-mobility, and industrial automation. Crucially, by addressing the severe 18-month lead-time bottlenecks for critical power distribution equipment, Siemens’ global capacity surge directly impacts fast-growing digital markets like Mexico, where unprecedented data center expansions are bottlenecked by grid connection wait times and a lack of available high-voltage infrastructure components.
Siemens AG announced it will invest €300 million to expand the production of key technologies for the global energy transition and for AI data centers. The investment encompasses a new supplier facility in Offenbach, Germany, and the expansion of the company’s two existing plants in Frankfurt am Main. Construction begins in July 2026, with production at the supplier facility starting in the spring of 2027. The investment will create up to 700 new jobs by the end of 2030.
The announcement is the European complement to a North American investment cycle Siemens has been executing throughout 2026. In March 2026, the company announced an investment of US$165 million in its US factories to support the rapid growth of AI and data centers. By expanding its manufacturing locations in Germany, Siemens is now taking a further step to secure the global supply of electrical switchgear.
Siemens is the only company worldwide that produces medium-voltage and high-performance switchgear systems at a single location, with decades of experience in development, manufacturing, services, quality assurance, environmental management, and test technology with an accredited test lab. The Frankfurt switchgear factory currently comprises two plants employing around 2,800 people in production, research and development, and automation. The factory is the company’s global center of competence for gas-insulated switchgear and is also a pioneer in switchgear that does not rely on the climate-damaging insulation gas sulfur hexafluoride. Instead, the switchgear’s fluoride-gas-free solutions use clean air gas comprising natural components from the surrounding atmosphere.
The specific product being scaled, medium and high-performance electrical switchgear, is the equipment that distributes power from transmission networks into buildings, industrial facilities, and data centers. It is not generation equipment. It is the infrastructure layer between the grid and the load. Siemens’ Smart Infrastructure Business booked record orders of €1.9 billion from data centers in 2Q26. In the first half of 2026, revenue generated by these technologies soared more than 45% to €1.8 billion.
The Supply Constraint That Is Driving the Investment
Demand for switchgear systems is continuing to increase worldwide, driven by the development of e-mobility and data centers, the increasing electrification of factories, and the growth of the technology industries. The rapid spread of AI, in particular, is accelerating investments in data center infrastructure and driving demand for efficient power distribution technologies.
That global demand surge is now the most direct constraint on data center construction timelines, not land, not fiber, nor permits. Electrical switchgear lead times globally have extended to 18 months or more in several categories, meaning projects that are financeable, permitted, and shovel-ready are still waiting for equipment that cannot be delivered. Siemens’ Frankfurt expansion is a direct response to that supply constraint, scaling domestic German production to close the gap between demand and delivery.
What This Means for Mexico
Mexico’s situation amplifies the global equipment shortage. Siemens has described its Mexican operations as capacity-constrained.
National data center operational capacity reached 279MW in April 2026, more than doubling from 115.5MW in 2024, with analysts warning that advancing without structural energy planning increases operational risks, delays projects, and reduces national competitiveness. MEXDC estimates the sector could reach 1,516MW of installed capacity by 2030, attracting over US$18 billion in direct investment. That trajectory depends entirely on whether switchgear and electrical distribution equipment is available to connect data center load to Mexico’s grid at the pace projects are being permitted and financed.
The transformers, switchgear, cables, metering systems, and distribution equipment required to connect new industrial and data center load to Mexico’s grid represent a substantial procurement opportunity that, under the Plan México framework, should increasingly be sourced from national manufacturers. That CANAME argument, presented at the 20th SIEC symposium in May, identifies the same supply chain gap that Siemens’ Frankfurt investment is designed to address at the global level.
