Correct Answer - Option 3 : uniform rate tariff
Explanation:
Electricity Tariffs:
Definition: The amount of money charged by the electricity supplier to various types of consumers is known as an electricity tariff.
The tariff covers the total cost of producing, supplying, Investment and profit.
The total bill of the consumer has three parts C = Ax + By + D
Where C = Total charge for a period (one month)
x = Maximum demand during the period (kW or kVA)
y = Total energy consumed during the period (kW or kVA)
A = Cost per kW or kVa of maximum demand.
B = Cost per kWh of energy consumed.
Ax = Semi-fixed charge
Bx = Runnig charge
D = Fixed charge
Types of Electricity Tariff
-
Flat Demand Rate tariff: The flat demand rate tariff is given by the equation C = Ax. The bill depends only on the maximum demand of the load.
- Straight-line/uniform meter rate tariff: This type of tariff is given by the equation C = By. The bill depends on the energy consumption of the load.
-
Block meter Rate tariff: The price and energy consumption are divided into three blocks. The first few units of energy at a certain rate, the next at a slightly lower rate and the remaining unit at a very lower rate.
-
Two-part tariff: The total bill is divided into two parts. The first one is the fixed charge and the second is the running charge.
-
Power factor tariff: The bill depends upon the power factor of the load.
-
Three-part tariff: The flat demand rate tariff is given by the equation C = Ax + By + D. Mainly applied to the big consumers.
