Siemens manufacturing plant in Pomona, CA

Over the past several years, Siemens has invested more than $690 million in U.S. manufacturing, strengthening American industry and job creation.

One result of this major investing effort is our expanded state-of-the-art facility at Pomona, California, which will be a central part of our effort to help transform U.S. manufacturing for the digital age.

Siemens invested $95 million to expand electrical-product production at the Pomona site and expects that the facility will generate 123 new jobs when the expansion process is complete.

"The electrical products we produce provide the critical underpinnings for America’s growing industry and infrastructure,” said Regional CEO of Electrical Products for Siemens Smart Infrastructure North America Barry Powell. “When examining our footprint in California, I’m proud that Siemens is both a pillar of the community, serving the area for more than 50 years, but also nimble enough to grow and modernize when our customers and the industry call for it."

The Pomona facility is already producing critical low-voltage electrical equipment such as switchboards and lighting panels. It will play a key role in expanding America’s manufacturing capabilities for essential electrical infrastructure that supports AI data centers, as well as for industrial, commercial, and construction markets, positioning it as a leading hub of innovation and efficiency in the state of California.

This facility is also on target to achieve LEED Gold certification, meaning that the facility will be carbon neutral and incorporate advanced water and power metering, a battery energy storage system and rooftop solar arrays. The canopy solar system will generate an estimated 1,638 MWh of power annually, powering 32-percent of the building’s energy needs and delivering an impressive 33-percent energy cost savings of the building’s operations.

The site expansion, occurring in two strategic phases, marks a transformative development for this legacy facility built in 1972. The completion of the first expansion phase involved the construction of the new 100,000-square-foot greenfield manufacturing facility adjacent to the existing building. The next phase, currently under development, will further enhance the site with 46,000 additional square feet of capacity by rebuilding, expanding and reimagining the existing facility. Upon completion, the new plant will be three times the size of the original 1972 factory.

The investment and expansion of our Pomona site is just one part of the latest chapters in Siemens long history of strengthening the company’s American manufacturing footprint.

Other recent investments include: A $36 million investment in our Wendell, North Carolina facility to expand its fabrication capacities, customer experience and workforce training. A $220 million investment in a new rail-manufacturing facility in Lexington, North Carolina, to establish a bicoastal “Made in America” rail-manufacturing footprint, and an expansion to our existing electrical products manufacturing plant in Grand Prairie, Texas, to meet booming demand for the electrification of critical infrastructure.

Siemens investments in U.S. manufacturing and infrastructure go beyond individual projects—they are a strategic force behind our efforts to meet the rapid growth of America’s energy needs and the broader economy. By leveraging cutting-edge technologies, Siemens is driving digitalization and automation, enhancing efficiency and creating thousands of skilled jobs across the nation. These initiatives support critical sectors like energy and transportation, helping to strengthen America’s leadership in global manufacturing and innovation. Siemens is proud to play a central role in modernizing U.S. infrastructure and ensuring its long-term competitiveness in the digital age.
