What the reviewed record shows
NIPSCO’s current multi-step base-rate increase was approved in Cause 46120 in June 2025, with the final step tied to 2025 plant balances. The IURC’s 2026 affordability presentation identifies the principal drivers as previously approved solar, storage and delivery-system investments. The Hobart Amazon contract and GenCo resources were approved later, in June 2026, under separate orders that assign project-related costs to Amazon or GenCo. At Amazon’s projected full load ramp, Cause 46322 estimates residential bill credits of about $7 per month, or $82 per year. A customer’s bill can still change because of usage, fuel factors and other riders, so a bill increase alone does not identify its cause.
