Tariff of electricity in India
IMPORTANT : All these costs are calculated on active power consumed. It is mandatory for the consumer to maintain a power factor of 0.8 or above otherwise penalty is levied on them depending on the deviation.
Let us now discuss about the tariff system existent in India for the DISCOMS. It is regulated by CERC (central electricity regulatory commission). This tariff system is called availability based tariff (ABT).
As its name suggest it is a tariff system which depends on the availability of power. It is a frequency based tariff mechanism which tends to make the power system more stable and reliable.
This tariff mechanism also has of 3 parts: Fixed charge + capacity charge + UI (Unscheduled interchange).
The fixed charge is same as that discussed above. The capacity charge is for making the power available to them and depends on the capacity of plant and the third one is UI. To understand the UI charges let us see the mechanism.
Mechanism of ABT
- The generating stations commit a day ahead about the schedule power which they can provide to the regional load dispatch centre (RLDC).
- The RLDC conveys this information to various SLDC which in turn collects the information from various state DISCOMS about the load demand from various types of consumers.
- The SLDC sends load demand to RLDC. And now RLDC allocates the power accordingly to the various states.
