Udall and other members of Congress are holding a news conference Wednesday to push for the tax credit, which is due to expire at the end of this year unless Congress renews it.
A study by a wind energy group found that 37,000 jobs, including hundreds in Colorado, would be lost if the credit expires.
Military veterans who have found careers in the wind energy industry are also lobbying for more federal support.
They're hoping to ramp up pressure Wednesday to extend the $12 billion break.
