For contracts in accordance with paragraph B of
Article 133 of the fifth plan
To calculate the adjustment for the electricity costs, four coefficients are
needed in the formula to be adjusted, all of which are announced by the central
bank of Iran's website:
1-Retail sale index at the beginning of the payment year.
2-Retail sale index at the beginning of the
contract conclusion year.
3-Average official currency (Euro) exchange rate
in the period of one year before payment.
4-Average official currency (Euro) exchange rate
in the period of one year before contract conclusion.
while the Alpha index is announced by the seller and the range is between 0.15
Items 1 and 2 are available through the following
Items 3 and 4 are available after entering the
beginning and the end of timetables and the currency type through the following
After entering the above items in to the formula, the
index coefficient that is rounded up to 5 decimals will be achieved. By
multiplying this coefficient to the base rate of power purchase (Article 2 of
special conditions of the contract), the unit price per kilowatt hour of
equivalent production will be specified in the bill which will be rounded up to
To calculate the equivalent production in order to insert into the renewable
electricity bill, the amount of net production of the power plant and also the
hourly coefficient are needed. Both of these items are available
through the website of Iran Grid Management Co.
The net production of the power plant will be given to the electricity seller
after entering the username and password given by Iran Grid Management Co. through

The usable hourly coefficient in order to set in any
bills is the last updated hourly coefficient which can be accessible through
the following link:
Equivalent production in any hour of the day will
be equal to net production of the hour multiplied in readiness coefficient of
the hour. Summing the equivalent production of all hours of the month will give
us equivalent production in order to be set in the bill. Multiplying the unit
price and equivalent production results in the total amount of the electricity
