TMEIC Corporation Americas has officially relocated its headquarters from Roanoke, Virginia, to Houston.

TMEIC Corporation Americas, a group company of Japan-based TMEIC Corporation Japan, recently inaugurated its new space in the Energy Corridor, according to a news release from TMEIC. The new HQ occupies the 10th floor at 1080 Eldridge Parkway, according to ConnectCRE. The company first announced the move last summer.

TMEIC Corporation Americas specializes in photovoltaic inverters and energy storage systems. It employs approximately 500 people in the Houston area, and has plans to grow its workforce in the city in the coming year as part of its overall U.S. expansion.

"We are thrilled to be part of the vibrant Greater Houston community and look forward to expanding our business in North America's energy hub," Manmeet S. Bhatia, president and CEO of TMEIC Corporation Americas, said in the release.

The TMEIC group will maintain its office in Roanoke, which will focus on advanced automation systems, large AC motors and variable frequency drive systems for the industrial sector, according to the release.

TMEIC Corporation Americas also began operations at its new 144,000-square-foot, state-of-the-art facility in Brookshire, which is dedicated to manufacturing utility-scale PV inverters, earlier this year. The company also broke ground on its 267,000-square-foot manufacturing facility—its third in the U.S. and 13th globally—this spring, also in Waller County. It's scheduled for completion in May 2026.

"With the global momentum toward decarbonization, electrification, and domestic manufacturing resurgence, we are well-positioned for continued growth," Bhatia added in the release. "Together, we will continue to drive industry and uphold our legacy as a global leader in energy and industrial solutions."
