This docket is a full base-rate review. Selected charges can change on separate schedules without reopening every issue in this case.
Full base-rate review
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.

Governing source ↗Investment Recovery Mechanism
Utility- and order-specific
An approved IRM can fund specified distribution investments between general rate cases. Collections and actual spending are reconciled under the terms of the utility's Commission order.
