The charged price is the base rate plus its adjustment. Adjustments carry fuel and rider costs and are frequently most of the bill, so a comparison built on the base rate alone is meaningless.

Effective rate includes the fixed charge, which is why it falls as usage rises. This is a time-of-use tariff, so the result also depends on when power is used; an average residential pattern is assumed. Details →
