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.

Other plans at this utility
Encoded from the same tariff book, on the same day. Which one
you are on is on your bill; which one you are eligible for is set by the
utility, not by this page.
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.
On-peak is 3:00PM-7:00PM Monday through Friday only. Weekends and the rest of the day are off-peak, which is why the weekend grid carries no peak hours at all.
Summer is June through September; winter October through May. Only the on-peak rate changes by season - off-peak is identical year round.
Not tiered: the 17 kWh/day allowance on D1 does not apply here.
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.
