TSEA Energy is investing $25m in a new manufacturing facility in Eden, North Carolina, marking its first industrial operation in the United States and expanding domestic production of critical grid infrastructure.
The project will create around 160 jobs in Rockingham County, with production expected to begin ramping up in the fourth quarter of 2026.
The facility will manufacture single-phase step voltage regulators for the U.S. market—equipment essential to maintaining stable voltage levels across electricity distribution networks. The move brings TSEA closer to its customer base while strengthening the domestic supply chain for power infrastructure components.
Beto Reynaldo, CEO of TSEA Energy, said: “Establishing a local manufacturing presence allows us to better serve our customers’ needs while contributing to the modernization of the U.S. grid.”
Expanding U.S. manufacturing capacity
The Eden plant will produce voltage regulators rated up to 1100A and 36.2 kV, incorporating advanced electronic controls, communications capabilities, and cybersecurity features.
TSEA currently manufactures in Brazil and supplies more than 40 U.S. utilities. The addition of the North Carolina facility is expected to at least double the company’s global manufacturing capacity.
Supporting grid modernization
The investment comes as U.S. utilities increase spending to upgrade aging grid infrastructure and accommodate rising electricity demand, alongside the growing integration of distributed energy resources such as solar, battery storage, and electric vehicles.
Voltage regulators play a critical role in managing these increasingly complex power flows, helping utilities maintain reliability and improve system efficiency.
Maurício Machado, COO of TSEA’s Voltage Regulator Business Unit, said: “This investment strengthens our ability to support U.S. customers more efficiently and reinforces our role in advancing a more reliable and resilient energy system.”
Regional impact
Located near the North Carolina–Virginia border, the site is expected to support regional industrial growth, creating roles across manufacturing, engineering, and operations.
North Carolina Governor Josh Stein welcomed the investment, highlighting the state’s workforce and strategic location as key factors in supporting grid modernization efforts.
