The blade manufacturer said it will employ the workers at its Grand Forks plant in North Dakota to deal with increasing demand from new wind projects in the US.
However, the new jobs amount to less than half the 340 roles that were cut at the Grand Forks plant in September last year. The cuts dropped the workforce at the factory to 270 in 2012, from its peak of 900 in 2008.
LM will use the grant to re-equip the factory for the production of a greater variety of blades, the company said.
The firm had indicated in October that it was considering hiring more workers at the Grand Forks factory, but had not specified the number of new positions.
The grant is part of $150 million in clean energy tax credits announced by the US Department of Energy, which provides developers with a 30% investment tax credit.
