This is a private contract rate for a data center developer, not a residential rate, but its minimum payment terms are meant to stop those costs from being shifted onto household bills.

Alliant Energy's Iowa utility also won Iowa Utilities Commission approval for an individual customer rate contract with QTS for its hyperscale data center campus at the Big Cedar Industrial Center in Cedar Rapids. Like the Vulpine Power contract for Google's site next door, it locks QTS into a long term minimum payment regardless of how much power it actually uses. Through April 2026 these were the only two such large load contracts Alliant had brought to Iowa regulators.
What it means for your bill: This is a private contract rate for a data center developer, not a residential rate, built to keep large new loads from raising costs for everyone else.
