Eaton is investing $340 million to increase U.S. production of its three-phase transformers. Production and hiring at Eaton’s new facility in Jonesville, South Carolina, is expected to begin in 2027. Eaton also will continue to manufacture three-phase transformers at two Wisconsin facilities.
“Electrical power demand is increasing dramatically, and our solutions are at the heart of energy systems everywhere, from the utility grid to industrials, data centers, buildings and more,” said Mike Yelton, president, Americas region, electrical sector, at Eaton. “We’re grateful for the strong collaboration and support in South Carolina, where we have a long history of manufacturing and innovation. Eaton is continuing to increase production and add jobs there and across the U.S. to support affordable, reliable and clean energy.”
Eaton will convert an existing facility in Jonesville, South Carolina, into a manufacturing site for three-phase transformers. The project is supported by local, state and federal economic development incentives. The company is also working closely with readySC and regional schools to support hiring and industry training.
“Eaton’s new operation in Union County, which will mean 700 new jobs for the local community, represents a major vote of confidence in South Carolina’s highly skilled, world-class workforce. This investment is a remarkable milestone for Eaton and Union County, and we celebrate the opportunities it will create throughout the state in the years ahead,” said South Carolina Governor Henry McMaster.
“South Carolina is a leader in manufacturing due to our talented workforce, quality of life and business environment. I welcome Eaton’s investment in Union County, further ensuring our state remains on the forefront of grid modernization,” said Senator Lindsey Graham.
Senator Tim Scott shared, “This is great news. Eaton’s investment and expansion will create more job opportunities for the community and stimulate our local economy. I am glad South Carolina continues to be a hotbed for economic growth and a leading force in energy.”
Congressman Ralph Norman said, "South Carolina continues to set the gold standard as a competitive, business-friendly state with a strong and growing workforce. I am thrilled that Eaton has chosen Union County for its expansion, and I look forward to the positive impact this investment will have in the years ahead."
Union County Supervisor Phillip Russell said, “We are pleased to welcome Eaton to Union County and acknowledge their investment and the new jobs opportunities they are introducing. Their considerable investment highlights the confidence global companies like Eaton have in Union County’s capability to address their needs. On behalf of the county council, county staff and our partners, we convey our congratulations and appreciation for Eaton’s commitment to Union County.”
In addition to continuing manufacture of three-phase transformers in Waukesha, Wisconsin, Eaton will also continue to produce single-phase, pole-mount and pad-mount transformers in Nacogdoches, Texas.
Since 2023, Eaton has invested more than $1 billion in its North American manufacturing for electrical solutions. Eaton is also increasing supplies of power distribution solutions, including transformers and voltage regulators; as well as electrical assemblies: switchgear, switchboards and circuit breakers; and solutions supporting electric grid infrastructure projects.
Founded in 1911, Eaton earned revenues of nearly $25 billion in 2024, with the company serving customers in more than 160 countries.
