A $5.13 billion federal loan guarantee package gives Alliant's regulated utilities access to ultra-low-cost, long-dated capital for grid and generation projects, potentially improving project economics and rate-base growth.
DOE Title XVII loan guarantees are a key federal financing tool for utility-scale energy infrastructure; this facility aligns with broader industry use of government-backed, low-cost capital for grid modernization and generation projects.
Mandatory prepayment triggers include failure to achieve 95% regulatory cost recovery from the Iowa Utilities Commission or Wisconsin PSC, change-of-control provisions (35%+ voting power threshold), and cross-default to other indebtedness exceeding specified thresholds.
