§525.60. Determination of Gas Charge(s)

a)         Each month the utility shall determine the Gas Charge(s) to be placed into effect for service rendered or billed during the effective month.

 

b)         The Gas Charge(s) shall be determined in accordance with the following formula:

 

GC

=

(G + A + O/T) x 100

 

Where:

 

GC	=	The Gas Charge(s) in cents per therm rounded to the nearest 0.01¢; any fraction of 0.01¢ shall be dropped if less than 0.005¢ or, if 0.005 or more, shall be rounded up to the next full 0.01. A utility may establish separate Gas Charges for each type of gas cost
G	=	The sum of the estimated recoverable gas costs associated with the base period, as prescribed in Section 525.40.  If separate Gas Charges are established, only costs related to the specific Gas Charge shall be included.
A	=	An amount representing the total adjustments to gas costs, as prescribed in Section 525.50.  If a utility has elected to amortize the total adjustments to gas costs, Factor A shall include the amount applicable to the base period.
O	=	An amount representing the additional over- or under-recovery for a reconciliation year ordered by the Commission to be refunded or collected, including interest charged at the rate established by the Commission under 83 Ill. Adm. Code 280.70(e)(1) from the end of the reconciliation year to the order date in the reconciliation pro­ceeding.  If the Commission determines it is necessary to amortize the additional over- or under-recovery, additional interest shall be charged in the same manner as that prescribed in Section 525.50 (b).
T	=	The estimated applicable therms of gas associated with service to be rendered or billed during the base period.
