The MPSC authorized less than half of DTE Electric's filed revenue request, maintained the 9.9% ROE, and made the new rates effective March 5, 2026.
DTE Electric requested a $574 million annual base-rate increase for a projected 2026 test year. The MPSC issued its final order February 19, 2026, authorizing approximately $242 million annually at a 9.9% return on equity, effective March 5, 2026.

State rules
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 rule ↗Between full reviews
Power and gas supply cost recovery
Variable surcharge · annual reconciliation
PSCR and GCR surcharges recover fuel, purchased power, transmission, and gas-supply costs above the amount in base rates. Actual costs are reconciled annually after a prudence review.
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.
