Rate-case process
Contested-case regulation of investor-owned electric and natural-gas rates.
A utility must obtain MPSC approval to increase rates. Staff and intervenors test the filing before an administrative law judge, and the Commission issues the final order; power- and gas-supply costs are reconciled through separate recovery mechanisms.

Full base-rate reviews set the broad revenue and return framework. Recurring riders, clauses, and reconciliations can change narrower charges between those reviews. These are governing patterns, not filing-date forecasts.

No fixed recurring interval
A utility files when it seeks a base-rate change. The MPSC's general framework does not impose a common annual or multi-year filing cycle, but it requires a final Commission decision within 10 months of the application.
Rate period: Filing-specific forecast, historical support, and standard rate-case schedules.

Utility- and order-specific
