The Centralia facility, which opened in 2012 with just 12 employees, has expanded nearly fourfold in square footage and now employs 141 people; employment at the Centralia site is expected to reach approximately 201 employees by the end of 2028. The $15.3 million investment from Intermountain Electronics is supported by a Reimagining Energy and Vehicles (REV Illinois) agreement with the Illinois Department of Commerce and Economic Opportunity.
