Energy rates

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 →

The utility's own description

This Schedule is applicable to private residences, single family dwelling units, and farms. Energy delivered to each residence, dwelling unit, or farm shall be separately metered, and shall include energy used for incidental, non-commercial purposes (e.g., swimming pools, garages and workshops). This Schedule is not applicable to recognized boarding or rooming houses or commercial establishments. Energy taken under this Schedule may not be resold or shared with others. The Authority, at its sole option, may place under this Schedule RT-17 Customers having tankless electric water heaters or other types of loads that are estimated by the Authority to have an annual load factor less than 35%. If at the Authority's option a Customer is placed on this Schedule RT-17 and after twelve consecutive months of service the Customer's annual load factor is greater than or equal to 35%, then the Authority shall remove the Customer from the Schedule RT-17 and credit or debit the Customer's usage for the previous twelve month period for any difference in billing under the Schedule RT-17 and the then applicable residential schedule.
