This document discusses different types of tariffs for electricity pricing: simple tariff, flat rate tariff, block rate tariff, two part/maximum demand tariff, power factor tariff, and three part tariff. It provides advantages and disadvantages of each tariff type. Block rate tariff divides consumption into blocks and charges different rates for different blocks. Two part tariff considers both maximum demand and energy consumption. Power factor tariff accounts for the power factor of the consumer's usage. Three part tariff has charges for fixed costs, maximum demand, and energy consumption. The document explains how tariffs are used for power requirement management and agricultural activities.

1. 1

2.  In last class we have seen about the protection of the
power system with the help of the relay and the other
methods employed, through which the power utilized
will be protected.
 In today’s class, types of tariff , which is nothing but
the cost rate for the power supply through which the
power can be delivered in the next proceses.

3. The tariff is the rate at which the
electrical energy is sold. There are various types of tariffs
followed in the market. This post will give the brief idea
about different tariff types.

4. 1- Simple Tariff
2- Flat rate Tariff
3 - Block Rate Tariff
4 - Two Part Tariff/Maximum Demand Tariff
5 - Power Factor Tariff
6 – Three Part Tariff

5. ADVANTAGES
:- This is simplest tariff.
:- Even a simple consumer can understand it.
DISADVANTAGES
:- There is no differentiation between small and
big consumers.
:- The cost is per unit is very high.

6. It is a type in which different consumers have different rates.
A discrimination exists between small and large consumers.
ADVANTAGES
:- Large consumers are encouraged in this type.
:- This tariff is simple and easy to calculate.
DISADVANTAGES
:- Different energy meters are required to be installed at
consumer’s premises.
:- The supplier doesn’t get any return for the connection
given to the consumer If he doesn’t consume any energy in
a particular period.

7. When the total energy consumed is divided into
blocks for the purpose of tariff.
ADVANTAGES
:- The consumers are encouraged to consume
more energy. This increase load factor of
the system and the cost of generation is reduced.
DISADVANTAGES
:- This doesn’t take into account the maximum
demand of the consumer.

8. This is the system in which the tariff is related to the consumer’s
maximum demand, and then, to his consumption of energy.
ADVANTAGES
:-This tariff is very suitable for industrial consumers who have
higher maximum demand.
:-It takes into considerations the maximum demand of the
consumer.
DISADVANTAGES
:-A maximum demand indicator is to be installed at the premises
for assessing the maximum demand of the consumer.
:-The consumer has to pay some fixed amount per kw whether he
consumes energy or not in a particular period.

9. The tariff in which the power factor of the consumer is
taken into consideration.
In this there are following types:-
(i)KVA maximum demand tariff
(ii)Sliding scale tariff/Average P.F Tariff
(iii)KWh and KVAR Tariff

10. The tariff which charges a consumer in 3 parts.
First Part
This represents fixed charge which includes
interest and depreciation.
Second Part
This is a semi-fixed charge which is calculated on
per kw of the maximum demand.
Third Part
This is a running charge which is calculated per
kwh of power consumed by the consumer

11.  Thus the tariff rate and the types of tariff rate which is
being utiliized for the certain power requirement
management and mainly the agricultural activities.
 In the next class, we will see how to remove the already
assigned value of power which appears to be wrong
and not satisfied by the system.
