Interruptible Power: An Economic Advantage to Industrial Users

Abstract

Energy costs have increased rapidly during the last several years and there is every indication that these costs will continue to rise in real dollars. In certain parts of the country power availability will be limited and in other areas energy costs will be nearly prohibitive. In view of this, it is imperative that utilities leave no stone unturned in developing methods that might reduce power costs and increase the power supply reliability.

Interruptible power has been utilized as one successful method by leveling demands and lowering costly and difficult-to-supply system peaks. Such power, offered to industrial customers in the TVA area in conjunction with firm power, benefits industry through lower power costs and provides TVA greater flexibility in operating its power system.

Interruptible power is a take-it-or-leave-it option for industry, but if it can be determined to be economical and technically feasible for specific industrial operations, TVA will work closely with the industry to implement the advantages afforded by interruptible power.
