MidAmerican Energy said Thursday a plan to scale back the federal wind production tax credit would remove the certainty the company has been counting on in its plans to expand wind power in Iowa.

The wind provision, included in the Republican tax plan in the U.S. House, would scale back the credit by limiting it to 1.5 cents per kilowatt-hour of electricity, down from 2.3 cents. The House Ways and Means Committee cleared the tax plan Thursday.

A Senate tax plan was scheduled to be released on Thursday, and some lawmakers on the Finance Committee have said it won't appear in that version, according to a report. But if the House provision were to prevail, it would put in jeopardy $50 billion in planned investments, according to the American Wind Energy Association, an industry group.

Wind advocates complain the House changes would also reverse a 2015 agreement in Congress to phase out the production tax credit over five years.

In a statement, MidAmerican said the agreement provided certainty for near term investments. "The House proposal removes that certainty, which MidAmerican Energy — and its customers — were counting on when it moved forward with plans to rebuild and repower more wind generation," the company said.
