State of play: A House panel will delve into expiring tax provisions Friday, which will likely provide an opening for debate on expiring wind-energy tax credits that renewable-energy companies and environmentalists are lobbying aggressively to extend.

A House Ways and Means Committee panel will gather for a hearing on various expiring tax provisions.

“The hearing will explore ideas on the framework that Congress should use to evaluate tax extenders, the principles of good tax policy that Congress should apply during this evaluation, and the specific metrics against which Congress should test the merits of particular provisions,” the committee said.
