DOE closes $5.1 billion loan to Alliant Energy for 2.6 GW in Iowa and Wisconsin
Alliant Energy has received a $5.1 billion federal loan package for projects in Iowa and Wisconsin, and the financing is now closed, the US Energy Department's lending office said. Unlike a conditional commitment, a financial close means the financing documents are signed.
According to DOE, the investments will add more than 2.6 GW of new or upgraded generation capacity, including new natural gas-fired power plants, energy storage systems and upgrades to existing facilities. The department says they will deliver more than $1 billion in electricity cost savings across the two states, supply the equivalent of nearly 2 million homes and create hundreds of construction jobs. It ties the loan to an executive order on strengthening the reliability and security of the US grid.
DOE describes the deal as the administration's tenth financial close and the sixth and seventh utility financings completed through the Energy Dominance Financing Program. The announcement does not break down how much of the 2.6 GW is gas, storage or upgrades, or give the loan terms.

What it means
The distinction from last week's $5 billion Constellation commitment matters: that one was conditional, this one has closed. The mix is the other point — a federal loan programme now financing gas plants alongside storage, framed around reliability rather than emissions. The $1 billion savings figure is DOE's own estimate, and without the split between gas, storage and upgrades it cannot be checked from the announcement.
