BOLINGBROOK, Ill., September 02, 2026--G&W Electric (www.gwelectric.com), a global leader in innovative power grid solutions, today announced the expansion of its North American manufacturing footprint with a new 291,305-square-foot facility in Romeoville, Illinois. The added space will increase production capacity, improve operational flow and support growing customer demand for technologies that strengthen reliability, resiliency and power quality across modern grid systems.
The expansion comes as utilities, commercial operations, and industrial users face a more complex electric landscape shaped by grid modernization, electrification, supply chain pressures and the accelerating forces of decarbonization, decentralization, and digitalization. Industry research projects U.S. electricity demand will grow by more than 50% through 2050, increasing the need for critical grid technologies that support a flexible, stable and more resilient electric system.
The Romeoville facility is the latest step in G&W Electric's broader expansion strategy, building on recent investments across its local and global operations. The announcement follows the company's expansion of its G&W Altea sensor manufacturing facility in Ferrara, Italy, reinforcing its commitment to increasing capacity for the technologies customers need to modernize the grid.
"For more than 120 years, G&W Electric has grown alongside the electric power industry, and this expansion reflects our continued commitment to supporting customers as the grid evolves," said John Mueller, chairman and owner of G&W Electric. "As demand grows and power systems become more complex, we are investing in the space, people and processes needed to deliver the reliable, high-quality solutions that strengthen grid resiliency and support dependable power delivery."
Located at 1135 Arbor Drive in Romeoville, the new facility includes roughly 30,000 square feet of office space. Specific manufacturing areas, including Viper® and Viper®-HV production, have transitioned to the new facility.
