MFG Announces Closure of South Dakota Manufacturing Plant

ABERDEEN, SD — June 8, 2021 — Molded Fiber Glass Companies (MFG) announced today the closure of MFG South Dakota, the company’s wind blade manufacturing plant located in Aberdeen, South Dakota.  The plant broke ground in 2007 and has been dedicated to the production of wind turbine blades.

The closure comes as a result of changes in market conditions, foreign competition and proposed revisions to tax policies impacting the wind energy industry in the United States.

The company will remain open to fulfill existing wind blade orders through August 6, 2021.

Teammates at the plant have been informed of the closure and will be privately informed of their individual separation dates.  The company is working in conjunction with the South Dakota Department of Labor and Regulation to assist teammates with reemployment benefits and to help with job search and placement.

At the time of the announcement, the company employed 300 teammates at the 315,000-sf facility.

MFG has been active in the wind energy industry since 1980.  In addition to blades the company manufactures wind turbine nacelles and spare parts at facilities in Texas and Alabama.  It also provides field and factory maintenance and repair services for wind blades.  These businesses will not be negatively impacted by the South Dakota facility closure.


Molded Fiber Glass Companies is a leader in the field of reinforced plastics and composites, serving diverse markets with a variety of composite material systems and processes.  A family-owned business for more than 70 years, the company has 14 operating entities throughout North America and is headquartered in Ashtabula, Ohio.
