Power Firm Pulls Plug On Troy Plant, 71 Local Jobs To Vanish

A longtime fixture in Troy’s industrial corridor is getting ready to shut off the lights. Trystar plans to permanently close its manufacturing facility at 1955 Stephenson Highway, a move that will eliminate 71 jobs. The company’s WARN filing shows separations are scheduled to begin on September 4 and continue through December 31, affecting production and service staff at the site.

According to the WARN notice filed with the Michigan Department of Labor and Economic Opportunity, Trystar will shutter its Oakland County worksite at 1955 Stephenson Highway and separate 71 employees. Those details were first reported by WhatNow. The filing lists affected job titles and the Sept. 4–Dec. 31, timeline, but it does not identify a replacement location or give a public reason for the move. The state’s WARN program posts notices and coordinates notifications to local officials and workforce partners.

Company Background and Recent Deals

Trystar, founded in 1992 and headquartered in Faribault, Minnesota, manufactures power-distribution and backup-power equipment, according to the company’s overview. In recent years, the company has expanded through acquisitions, buying Asentria in 2025 to add remote monitoring and controls and acquiring Island Technical Installations (ITI) in January 2026 to broaden its switchgear and field-services capabilities. Trystar’s company overview and the Asentria and ITI announcements outline the strategy behind those deals.

What Workers and Troy Can Expect

The WARN filing triggers state and local notification so Rapid Response and Michigan Works offices can start planning re-employment assistance, training, and unemployment-claims support for affected staff, according to the Michigan Department of Labor and Economic Opportunity. Local officials had not issued a public statement at the time of reporting, and the company did not include a reason for the closure or identify a new facility in its filing. Affected employees typically receive information on job-search services, retraining options, and benefit applications through those state channels.

Legal Timeline and WARN Notes

The federal WARN Act generally requires covered employers to give 60 days' notice for a plant closing or mass layoff, and the U.S. Department of Labor maintains compliance guidance and resources for workers and employers. Trystar’s schedule in the state filing begins Sept. 4, 2026, which establishes the statutory notice window for workers to access state re-employment services and apply for benefits.
