U.S. Sen. Chuck Grassley (R-Iowa).

WASHINGTON, D.C. – Clean energy advocates are applauding Sen. Chuck Grassley’s (R-Iowa) leadership to support the wind and solar energy industries in the One Big Beautiful Bill Act.

Grassley successfully got the wind energy industry off the ground by instituting America’s first-ever federal wind energy tax credit in 1993, earning him recognition as the “father” of wind energy production.

In the One Big Beautiful Bill, Grassley fought hard to improve the transition period for planned wind and solar projects by providing a 12-month runway after the bill’s enactment for projects to begin construction, allowing them to qualify for years-worth of tax credits by meeting this one requirement within a calendar year. This will supercharge near-term growth for the industry and protect workable standards for projects.

Grassley secured another significant victory for the wind and solar industries by striking a punitive new tax on wind and solar from the final version of the bill. Renewable energy is critical to Iowa, which generates 60 percent of its energy from wind power alone.

Here’s what they’re saying:

Alliant Energy:

“Senator Grassley’s leadership in advancing the legislation reflects a strong, principled commitment to securing America’s energy future by securing a financially viable phase out for the clean energy tax credits over the next few years. The provisions secured by Senator Grassley demonstrates his commitment to supporting customer affordability and [are] critical in preventing electric rate increases. His leadership also provides energy companies with electric generation resource planning certainty – a critical requirement to meet the growing energy demands of Iowa, and the nation.”

“As the law moves toward its implementation’s phase, we look forward to working with Senator Grassley and the Administration on the customer benefits of this law. His focus on practical, pro-growth energy solutions honors the intent of President Trump’s executive actions–prioritizing energy independence, reliability, and affordability for American families and businesses. We applaud Senator Grassley for championing policies that strengthen our energy infrastructure while supporting job creation and long-term investment in the heartland and across the country.”

MidAmerican Energy:

“Improvements made to the final budget reconciliation bill will give MidAmerican a pathway to execute on clean energy projects in our development pipeline for the benefit of our customers – and those improvements simply would not have happened without the leadership of Senator Grassley working in strong partnership with Senator Ernst. Planning certainty is critical for a business like ours, and their collective efforts will help us maintain safe, reliable and affordable service in Iowa and across our entire service area.”

American Clean Power:

“Senator Grassley has once again shown leadership protecting jobs and ensuring a cost-effective, reliable, and diverse power mix for Iowa. His leadership remains more important than ever to ensure that the administration implements the legislation fairly, and in a manner consistent with congressional intent.”

The Business Council for Sustainable Energy:

“The Business Council for Sustainable Energy thanks Senator Chuck Grassley for his leadership and support of the energy tax credits under the One Big Beautiful Bill Act. Thanks to his actions, the law adopts a more workable transition for many energy tax credits, enabling businesses to plan, invest and create jobs.”
