How DTE Energy differs from the Michigan average
Eligibility / billing boundary: Published DTE base electric rates for Overnight Savers (D1.13). The $8.50 service charge and matching RIA credit are not allocated to a marginal charging session; customer-specific taxes or other bill items can still apply.
The state average is a benchmark, not a substitute for this tariff. A low or high encoded period is a marginal energy price and should not be interpreted as a complete monthly bill unless the page explicitly says whole-bill modeling is supported.
