In the case of type 2 contracts, there is a large unit tank that is filled when units are purchased
from the operator or through net metering.
The customer has a credit balance expressed in units, which is consumed in 2 ways (binomial
tariff):
 by consumed units.
 by fixed price, this fixed price is subtracted every hour and is recalculated according
to the following equation:
Fixed price = (Price of contracted power x Contracted power )
+ Net metering access charge
+ Other costs

Figure 14:Representation of the consumption in the unit tank
Two energy meters are used to control the unit tank:
 a unit meter, which measures the units in the tank. These units will decrease as the
subscriber consumes energy and increase when units are purchased from the operator
or through the net metering balance.
Under normal conditions, the 1Wh to 1 unit ratio is 1:1.
an energy block meter, which is used when the price of energy depends on the con-
sumption level of the user during a period of time.
This type of contract can have no definite time limit, Open-ended contract, with no additional
costs included in the price of energy. Designed for buildings that are not charged for the use
of energy, such as cultural centres, churches, etc.
