by time of day and by day of week and by season · plus $10.00 per month · covers the full bill — everything the utility bills for energy - directly comparable to another bundled rate

Monthly bill

Usage	cheapest hours	most expensive hours
500 kWh	$84.24	$203.31
1,000 kWh	$158.48	$396.63
2,000 kWh	$306.96	$783.26

This plan prices by time of day, so a monthly total alone does not determine the bill. The columns are the bounds: every kWh in the cheapest period, and every kWh in the dearest. A real bill falls between them, and where it falls is what this plan is asking you to change. Before taxes, franchise fees and any local surcharge.

Plan	Energy	Fixed
D1 Residential Service (tiered)	21.53-22.82c/kWh	$10.00/month

What this figure does and does not include

Transcription notes recorded when this tariff was encoded, including anything deliberately left out.

Michigan, not California: no baseline territories or climate zones. Rates are the same statewide across DTE's service area.
Total energy rate = Power Supply Capacity + Power Supply Non-Capacity + Distribution, all stated separately on the filed sheet.
Service Charge $8.50/month.
Rates are filed in CENTS per kWh and converted here. DTE's whole book uses cents; PG&E and SCE use dollars. Mixing the two silently would be a 100x error, so the conversion is explicit and asserted in the golden tests.
Three periods: on-peak 3-7pm weekdays, super off-peak 1am-7am every day, off-peak the rest. Unlike D1.11 this schedule states its own distribution charges per period rather than one flat rate.
The spread is the point: summer on-peak 0.35559 against super off-peak 0.11744, a factor of 3.0. This is an EV and battery rate.
Super off-peak is identical in both seasons.
THE SURCHARGES ARE NOW ENCODED, AND THEY WERE 14.5% OF THE BILL. This tariff previously excluded the C8.5 and C9.8 surcharges because the rate schedule sheet cites them without inline values. They are tabulated per schedule elsewhere in the same rate book. Before they were added a 1,000 kWh bill came to $199.85 against the Michigan PSC's published $233.76.
