As of 2023, the principal divisions of Siemens are Digital Industries, Smart Infrastructure, Siemens Mobility, Siemens Healthineers and Siemens Financial Services, with Siemens Healthineers and Siemens Mobility operating as independent entities. Siemens also operates a number of "Portfolio Companies" with market-specific offerings. Other business units of the company include Siemens Technology (T) for
research and development, Siemens Real Estate (SRE) for corporate
real estate management, Siemens Advanta for
consulting services (including the
management consulting division Siemens Advanta Consulting), next47 as a
venture capital fund, and Siemens Global Business Services (GBS) as a
shared services unit. In June 2023, Siemens launched a new open digital platform called "Siemens Xcelerator", which houses a curated portfolio of IoT-enabled hardware, software, and digital services from both Siemens and third parties. Siemens also announced a partnership with
Nvidia, aiming to leverage its Omniverse platform with its 3D design capabilities. Xcelerator is part of a broader industry trend towards digital environments ("
metaverses"), and is delivered through a
software as a service (SaaS) subscription model, targeting accessibility for a range of businesses including small and medium-sized enterprises. In October 2023, Siemens and
Microsoft launched the Siemens Industrial Copilot, a generative AI assistant integrated into Siemens' industrial software. The system uses Microsoft's Azure OpenAI Service and
large language models for applications in automation, simulation, and system configuration. In March 2025, Siemens acquired Altair Engineering for $10 billion. Following the acquisition, Altair was integrated into Siemens' Digital Industries division, with its simulation technologies incorporated into the Xcelerator digital twin platform.
Smart Infrastructure Siemens Smart Infrastructure offerings are categorized into
buildings,
electrification, and electrical products. Its buildings portfolio includes
building automation systems,
heating, ventilation, and air conditioning (HVAC) controls, and
fire safety and
security systems, and energy performance services. The electrification portfolio is dedicated to
grid resilience and efficiency, encompassing
grid simulation, operation control software,
power-system automation and protection, and medium to low voltage
switchgear. Moreover, it includes
charging infrastructure for electric vehicles. In the realm of electrical products, the division offers low-voltage switching, measuring and control equipment, distribution systems, and medium voltage switchgear. By using primarily renewable energy, microgrids reduce carbon-dioxide emissions, which is often required by government regulations. It supplied a sustainable storage product and microgrids to Enel Produzione SPA for the island of Ventotene in Italy. File:Buona Vista MRT Station 202406.jpg|
