Newton has two of the largest manufacturers of wind turbine components in the state, and both Trinity Structural Towers and TPI Composites Inc. are invited to Iowa Wind Energy Day on Wednesday.

The event will take place from 8 a.m. to noon at the Iowa State Capitol in Des Moines. Gov. Terry E. Branstad will be the featured guest speaker at the event.

“It’s one of our most important educational days,” IWEA Executive Director Harold Prior said. “We want to work on educating politicians and visitors. Wind energy experts will be in attendance.”
