Key Issues
- —
MidAmerican Energy solar cost recovery and rate base treatment: IUC review of MidAmerican's large-scale solar additions and associated transmission upgrades under Iowa's rate review framework, with intervenor scrutiny on whether renewable capital costs are being shifted to captive ratepayers without commensurate bill savings.
- —
Alliant Energy (IPL) electric rate case and multi-year rate plan renewal: IPL's pursuit of a successor multi-year rate plan following expiration of prior agreement, involving disputes over capital expenditure forecasts, ROE, and allocation of clean energy transition costs between Iowa and Wisconsin jurisdictions.
- —
Utility-scale wind and solar interconnection queue congestion on ITC Midwest transmission system: Significant backlog of Iowa renewable generation projects seeking interconnection, raising IUC interest in transmission planning adequacy and whether SPP integration under the Southwest Power Pool affects Iowa ratepayer costs and resource adequacy.
- —
Rural broadband deployment over electric cooperative infrastructure: Legislative and IUC-adjacent debate over whether Iowa electric cooperatives should expand into broadband service using pole and conduit assets, including questions about cross-subsidization, easement rights, and coordination with Iowa Utilities Board's telecommunications jurisdiction.
- —
Water utility infrastructure surcharge (DSIC) proceedings and rate adequacy: Multiple small and mid-size IUC-jurisdictional water utilities seeking distribution system improvement charge approvals or base rate increases driven by EPA lead service line replacement mandates and aging infrastructure compliance costs.
Upcoming
Estimated deadline for IUC decision or procedural order in Alliant Energy (IPL) electric rate case docket; final briefs from intervenors including the Iowa Office of Consumer Advocate expected in advance of commission deliberations on multi-year rate plan terms.
Estimated date for MidAmerican Energy to file its next annual renewable energy rider or rate adjustment application with the IUC reflecting 2025-2026 solar and wind additions; triggers standard IUC review and OCA intervention window.
Estimated IUC compliance filing deadline for Iowa jurisdictional water utilities under EPA Lead and Copper Rule Revisions; IUC staff expected to assess whether utilities have adequately reflected LCRR capital plans in pending or future rate filings.
Estimated date for IUC evidentiary hearing in any contested water utility base rate case filed in early 2026; proceedings involving DSIC reconciliation and infrastructure surcharge caps are anticipated to reach hearing stage by Q4 2026 under standard IUC procedural schedules.
