Power bills in Dallas County
Most of the county is served by MidAmerican Energy.
MidAmerican Energy is asking the commission for a 5.2% residential increase (MidAmerican Energy natural gas rate increase (docket RPU-2026-0001)). On a $58 monthly bill that is about $3 to $5 a month. This case does not set rates directly, but the new solar plant it approves will eventually be paid for through customer rates, and MidAmerican has said data center growth is a major reason it is needed.
MidAmerican Energy's proposal would raise a typical residential customer's monthly natural gas bill by about 2.89 dollars, roughly 5 percent, and a temporary interim rate increase subject to refund has been in effect since around July 17, 2026. The Iowa Utilities Commission held public consumer comment meetings on September 8 in Cedar Rapids, September 9 in Des Moines and virtually, and September 10 in Sioux City, all in 2026, where MidAmerican reiterated its request; no settlement or decision date has been reported, and the company's prior gas rate case took roughly nine months from filing to a final order.
