MidAmerican Energy Company Responds to Iowa Utilities Commission Staff Questions

Strategic Insights -

MidAmerican Energy Company, in a response to three questions from the Iowa Utilities Commission (IUC) staff dated May 8, 2025, clarifies discrepancies in its first quarter (1Q) 2025 exhibition filing, Docket No. EAC-2025-0156. The company's responses address concerns regarding billing calendar discrepancies, invoice recording, and customer billing cycles.

The response reveals that MidAmerican's billing calendar does not perfectly align with the monthly calendar, leading to situations where customers are issued two bills for different billing months in one calendar month or no bill in another calendar month. This discrepancy is cited as the reason for the varying invoice amounts and billing cycles presented in the 1Q 2025 exhibit. The company also notes that its billing process is recorded based on the months in which the invoices are supplied, rather than the calendar months in which they are issued.

Furthermore, the response clarifies that the submitted 1Q 2025 exhibit II is outdated and contains incomplete information for March 2025, requiring a revision to accurately reflect the billing information. The company has provided the revised confidential exhibit, denoted as Exhibit II - Revision - CONFIDENTIAL, to address the queries.
