Molded Fiber Glass is laying off one-fourth of its workforce in Aberdeen.
Plant manager Dave Giovannini says that 92 people are losing their jobs. About 370 people worked at the plant.
Giovannini cites a drop in orders for wind turbine blades related to the uncertainty about the future of a federal wind energy production tax credit.
Employees being laid off are getting a financial package that includes a health care benefit and some profit sharing.
