Evidence
  1. [0]March is period 0 (winter) on the assigned tariff's weekday schedule, which corresponds to an energy rate of $0.1664/kWh, but the bill charged $0.1899/kWh.

  2. [1]The billed effective energy rate of $0.1899/kWh does not match the tariff's period 0 rate of $0.1664/kWh.

  3. [2]The billed effective energy rate of $0.1899/kWh also does not match the tariff's period 1 rate of $0.20748/kWh.

  4. [3]The billing period (March 2015) falls within the tariff's effective window (2014-01-01 to 2015-12-31), so tariff-superseded is ruled out.
  5. [4]The fixed charge of $9.56 matches the tariff's fixed charge, confirming the correct tariff is assigned and only the energy rate is anomalous.

Recommended action (internal)

Re-rate the energy charge using the period 0 (winter) rate of $0.1664/kWh for the full 8,400 kWh, since March falls entirely in winter under the weekday and weekend schedules; correct the line item and total prior to posting.
