Iowa renewable energy siting fights set to intensify in 2027, researchers warn
Iowa renewable energy advocates should prepare for a defensive battle at the Statehouse in 2027 as researchers predict the coming year will be the biggest yet for energy siting legislation across the country. The warning comes from a new analysis by the Siting Solutions Project, a nonpartisan initiative tracking renewable energy siting and permitting bills in state legislatures nationwide.
According to the report, more than 200 energy siting bills were introduced during 2026 legislative sessions, with 43% categorized as restrictive toward renewable energy development. Only 36% of bills would have had a positive impact on renewable energy deployment. Less than 30 bills were enacted, and just two of those were considered restrictive.
What the data shows about restrictive and permissive bills
Restrictive bills typically included policies that increased local zoning authority, added procedural burdens to permitting, made decommissioning more costly, expanded setbacks, or restricted projects based on agricultural and environmental impacts. Permissive bills generally created statewide standards, streamlined permitting, offered financial incentives, or reduced barriers to building on certain sites.
Nelson Falkenburg, a siting policy manager with Clean Tomorrow and co-author of the report, said many restrictive bills may have been introduced for political messaging rather than serious policy goals.
It's possible that many of the restrictive bills introduced in 2026 were messaging bills, where legislators were scoring political wins for their constituents by beating up on wind and solar, Falkenburg said.
Utah enacted a bill removing solar incentives on agricultural land with restrictive decommissioning standards. Kentucky passed a new law creating punitive siting standards for renewable projects in unzoned counties. Alabama took a permissive approach by making it easier to convert oil and gas wells into renewable energy sites.
How Iowa stacks up in the 2026 analysis
The report flagged seven bills in Iowa: three permissive, three restrictive, and one neutral. None of the Iowa bills tracked by the project were enacted in 2026.
Iowa's restrictive proposals included a bill requiring environmental studies, insurance, and proof of community benefit for projects. A neutral bill would have required aircraft detection lighting systems on wind turbines to address landowner complaints about blinking red lights.
A notable permissive bill would have created renewable energy siting language for counties to adopt, setting standards for moratoriums, setbacks, property tax, and other considerations. While similar bills advanced from committees in both chambers, neither reached the floor for a vote.
Researchers noted that Iowa's siting policy was turned on its head following an Iowa Utilities Commission decision to approve a generation certificate for a solar project in Cerro Gordo County, which preempted the county's ban on wind, solar, and battery storage projects.
What to expect in 2027
Falkenburg said the IUC decision means renewable energy advocates will likely shift from pushing permissive policies to defending the commission's authority to preempt local ordinances. The report specifically notes that clean energy advocates will be on the defense in Iowa and Texas to shore up permitting paradigms.
Falkenburg said making the business case to Republican leadership in Iowa will be key.
Advocates are going to have to be really closely tracking any renewable energy legislation that's introduced or advancing in the state, and making the case to the IUC, to Iowans, and to the Legislature that the projects that are coming online in Iowa are addressing the needs of Iowans and the business community, Falkenburg said.
The report shows Republicans tended to introduce more restrictive bills while Democrats favored permissive ones. However, Alex Brekel, senior director of programs for Clean Tomorrow, said partisanship tells you little about the quality of a state's siting policy regime.
Or at least the partisanship of a state tells you very little about the quality of the wind, solar, battery siting policy regime, Brekel said.
Falkenburg pointed to Texas as a prime example of a Republican-dominant state with significant renewable energy and very little siting regulation. Meanwhile, states with mostly Democratic bases tend to favor clean energy policies creating effective state siting regimes.
Data centers and electricity costs driving the debate
Researchers said data center growth and rising electricity bills will likely drive conversations around renewable energy siting policy in 2027. Falkenburg called it the biggest year yet for renewable energy siting and permitting legislation.
2027 is going to be the biggest year yet for renewable energy siting and permitting legislation, considering both the trends of data center buildout and the rising electricity bills that Americans are seeing that are affecting their wallets, Falkenburg said.
The Siting Solutions Project maintains a weekly updated legislative tracker with state-specific information on renewable energy siting policies across the country.
FAQ: Iowa renewable energy siting in 2027
What does the IUC preemption decision mean for Iowa counties?
The Iowa Utilities Commission's approval of a solar project in Cerro Gordo County preempted the county's ban on wind, solar, and battery storage projects. This means the IUC can override local ordinances when granting generation certificates for renewable energy projects.
Which Iowa bills were tracked in 2026?
The Siting Solutions Project tracked seven Iowa bills: three permissive, three restrictive, and one neutral. None were enacted during the 2026 session.
Why are restrictive bills being introduced if few pass?
Researchers suggest many restrictive bills serve as messaging tools for legislators to score political wins with constituents, even if they never advance out of committee.
