A southeast Iowa factory that makes wind turbine blades has recalled some workers laid off last fall as orders increase.
Plant manager Tony McDowell says new orders are coming in and as business expands the work force will be increased to match demand. Some of the new orders are coming from projects in Brazil and Chile.
More than 400 workers received layoff notices in September.
The company blamed difficult market conditions, lack of congressional action on a wind energy tax credit, and increased use of natural gas-fired power plants.
Congress passed tax credit extension in January.
