MidAmerican customers are already paying a temporary increase while the case is reviewed; if the full 2.89 dollar a month request is approved as filed it would stay in effect, and it does not involve data centers.

On billsafter the decision
MidAmerican Energy filed a request with the South Dakota Public Utilities Commission on August 18, 2026 to raise natural gas delivery rates, which as proposed would add about 3.83 dollars a month, roughly 8.2 percent, to a typical residential bill. The commission suspended the increase for 180 days from the filing date while it reviews the case. A customer petition in the Sioux Falls area gathered enough signatures to require a public hearing under state rules; no hearing date or decision date has been set yet.
What it means for your bill: If approved as filed, this would add about 3.83 dollars a month to South Dakota MidAmerican gas bills, but the increase is suspended while regulators review it and a public hearing is still being scheduled.
