Time-off-day tariff:-

In addition to basic tariff (Maximum Demand Tariff / KVA Maximum Demand Tariff / Load factor tariff also the tariff in which P.F. of industrial consumer is taken into consideration.) Consumer has to pay energy consumption charges according to time for which energy is consumed. TOD energy meter is installed in the consumer premises. This meter is specially designed to measure energy consumption w.r.t. time. This type of tariff is such that energy consumption charges/unit are less at during Offload period Energy consumption charges/unit are more during PEAK -load period This type of tariff is introduced to encourage industrial consumers to run their maximum load during OFF-load period.


Peak-off-day tariff: 

Energy consumption charges/unit are more during PEAK -load period This type of tariff is introduced to encourage industrial consumers to run their maximum load during Off-load period.

In this tariff expect TOD metering the timer with energy meter facility is provided in the consumer premises, for the consumers there may be some type load. e.g: Heating, pumping, refrigeration, agriculture load can be made off during peak period. Whenever total connected load on power station is less. The consumers load become ON which is less charged
