|Tier 1: Each monthly billing period begins at the lowest rate. While you want to stretch as far as possible, average customers use all of Tier 1 in about 15-20 days.|
|Tier 2: With about one third the allotment of Tier 1, Tier 2 costs slightly more (+2¢). If your Tier 1 lasts 15-20 days, Tier 2 could last another 5-6 days.|
|Tier 3: The rate increases dramatically (+17¢) in this tier. Customers who enter Tier 3 are consuming significant amounts of electricity.|
|Tier 4: Finally; if you enter tier 4, you are using more than twice your Tier 1 total, and the rate increases by an additional 4¢.|
NOTE: This chart represents an above average usage customer.
The length of time in each tier depends on monthly energy usage.
