Encoded tariff periods
All period choices stay inspectable; CalcuRiver never hides the rate behind a single blended number.

Use this plan in the shared calculator engine
The links preselect this utility. EV charging opens the recurring charging-window profile; other tools keep an explicit verified-period selection unless their own schedule model applies.
Rate version & freshness
This tariff snapshot is versioned and source-attributed. When a verified rate changes, CalcuRiver keeps this version in history and adds a new one instead of silently overwriting it.

Plan vs. Michigan benchmark
Encoded periods are used only for the contexts supported by this tariff model. CalcuRiver does not turn one TOU period into a fake all-in monthly bill.
