Energy Department Closes $5.1 Billion Alliant Energy Loan, Expanding a $3 Billion Biden-Era Commitment

The Energy Department's Office of Energy Dominance Financing (EDF) announced Wednesday, Oct. 28, that it had closed a $5.1 billion loan package to Alliant Energy. The announcement came alongside a conditional loan commitment to Constellation for nuclear uprates, which still has to clear technical, legal, environmental and financial conditions. Alliant's loan, by contrast, is final.

The money goes to Alliant's two utility subsidiaries in Iowa and Wisconsin. An Alliant filing with the Securities and Exchange Commission shows about $1.6 billion for Wisconsin Power & Light and $3.5 billion for Interstate Power and Light.

What the loan pays for

The Energy Department says the projects will add more than 2.6 gigawatts of new or upgraded generation capacity. That covers new natural gas plants, energy storage systems, and upgrades to existing plants. The department says it is enough to power nearly 2 million homes.

Alliant's own breakdown, as relayed in its press release, is 1.6 GW of new natural gas generation, 240 megawatts of added capacity at existing gas facilities, and a gigawatt of storage. It also includes 2 billion cubic feet of liquefied natural gas storage.

The loan runs 30 years. Under the terms in the SEC filing, Alliant has until May 15, 2056, to repay. It owes only interest until the first principal payment comes due in 2052. The interest rate tracks the government's borrowing costs, but the markup on top is a fixed percentage. It does not rise if lending to Alliant gets riskier.

The savings and jobs claims

The numbers differ depending on who is speaking. The Energy Department says the investments will deliver "more than $1 billion" in electricity cost savings and create "hundreds" of construction jobs. Alliant estimates "up to $1.2 billion in cumulative customer savings" and "more than 1,600 local jobs." An Alliant spokesperson told The Gazette of Cedar Rapids that Iowa customers would see $800 million in savings if the company receives the full package.

The department says the savings come from lower interest rates than commercial banks would charge, and that Alliant is required to pass them to consumers. It describes the remaining loan terms as business confidential.

"The Energy Department is delivering on President Trump's promise to lower electricity costs and unleash the full potential of American energy," Energy Secretary Chris Wright said. The loan is part of the department's response to Trump's April 2025 executive order on grid reliability.

A Biden-era commitment, enlarged

Alliant was not new to this program. The Biden-era Loan Programs Office had already tapped the company for up to $3 billion in potential loans to the same two subsidiaries. That deal was conditional. The Trump-era package is $2.1 billion larger.

Reason magazine argues the administration is claiming credit for what is essentially a repackaged Biden commitment. It says the earlier version was meant to finance clean energy and battery storage projects, and the new one drops the climate conditions. The Energy Department has not described the loan as a continuation of the earlier commitment. It calls it the Trump administration's tenth financial close and the sixth and seventh utility financings through the Energy Dominance Financing Program.

By the department's figures, the program had issued $132 billion in loans and guarantees as of Sept. 30. That includes $47.5 billion in conditional commitments. About $53.2 billion has been disbursed. EDF manages loan programs with a combined authority exceeding $300 billion, according to its strategic plan.

That is a lot of federal credit extended to private utilities. The upside is lower borrowing costs that Alliant is required to pass on to consumers. The exposure sits with taxpayers if a project falters. Both the Biden and Trump versions of this deal put federal credit behind a private company's capital plan.

R Street Institute's Tom Opdyke called the arrangement "another example of the current Energy Department distorting the power generation market." Reason also points to Simply Wall St. projections that Alliant's revenue will grow 6.8 percent annually over the next three years, arguing that makes the federal lending look even less necessary.

The political backdrop

Reason's headline ties the loan to the coming midterm races in Iowa and Wisconsin. Reason notes the Cook Political Report rates the Iowa Senate race a toss-up, and that several incumbent House Republican seats in Iowa and Wisconsin lean Democratic. An Alliant spokesperson told Reason the company spent "months reviewing the details and finalizing contracts" before the package "was finalized this week." The Energy Department's announcement cites the executive order and electricity demand, not the election.

Opdyke, for his part, doubts the timing would help anyone politically: voters' opinions "aren't likely to shift on the promise of future jobs and savings," he said.

CNN has tallied a run of rally promises from Trump tied to election results. He said in Sioux City, Iowa, on Oct. 22 that he would make year-round E15 permanent if Republicans win. At another stop he told voters that hurricane disaster relief for North Carolina depended on a Republican victory in the Senate race, before saying he was "only kidding." The Alliant loan is a separate matter from those promises, and the sources do not connect the two.

Which projects get built

Alliant's spokesperson told The Gazette the company is considering applying the money to the Bobcat Energy Center, a 720-megawatt gas plant planned in Marshalltown, Iowa. Construction is expected to start at the end of this year, with up to 360 construction jobs and about $711,000 a year in generation replacement tax.

Other candidates include the Lansing Battery Energy Storage System at a retired coal plant site, expected online in the spring. Alliant is also seeking to build the 94-megawatt Cedar River Generating Station in Cedar Rapids.

It is not yet clear whether any of the loan will support the proposed Morgan Valley Energy Center in rural Linn County, a 720-megawatt gas project. The Linn County Board of Supervisors recently rejected the company's rezoning application; if the Iowa Utilities Commission approves a generating certificate, the plant can be built without county approval. Alliant has not said how the $5.1 billion will be divided among projects.
