DENVER (AP) – Colorado lawmakers from both parties are trying to save a federal incentive for the wind industry.

Eight members of the congressional delegation signed a letter Tuesday asking for an extension of the wind energy production tax credit. A conference committee is negotiating the fate of the credit, which is due to expire at the end of the year.

Rep. Doug Lamborn of Colorado Springs is the only delegation member who didn’t sign on.

The credit helps offset the cost of electricity production during a wind farm’s first 10 years. Colorado lawmakers say it’s helped drive economic growth in Colorado in the wind industry.

Wind-turbine maker Vestas has three plants in Colorado. It has said U.S. jobs could be at risk if Congress fails to extend the tax credit.
