BRIGHTON - Vestas said Wednesday that it's consolidating its three U.S. research and development operations in Brighton amid a market slowdown due to uncertainty on whether Congress will renew a wind tax credit.

Vestas will move its operations in Louisville, Houston and Marlborough, Mass., to Brighton, where it's establishing a wind turbines R&D hub. The Danish turbine maker already has two factories in the Northern Colorado city.

"This consolidation represents a renewed commitment to Colorado and its renewable energy cluster," Vestas spokesman Andrew Longeteig said in an e-mail.

Vestas employs about 100 R&D people, but it's unknown how many will end up in Brighton. The company will give those employees an opportunity to transfer to Brighton.

Longeteig added that the company had reduced its workforce, primarily in its R&D division, in the U.S. and Canada last week. The reduction amounted to about 1.5 percent of its total U.S. and Canada workforce.

There were no layoffs at its Brighton and Windsor factories as part of last week's workforce reduction.

Vestas is consolidating as part of a global effort to scale its research activities, focus on product development
