Section 525
Section 525.10 Applicability
a) The Gas Charge(s) shall be applied to all therms associated
with the service classifications so identified in the filed rate schedules of
all gas public utilities operating in the State of Illinois. If a utility
elects to establish separate Gas Charge(s) for recovery of costs of a seasonal
nature, such Gas Charge(s) shall be applied to therms associated with the
appropriate seasonal period. The Gas Charge(s) shall be applied either to each
therm billed during the effective month or to each therm delivered during the
effective month. The utility shall elect whether a billed or a delivered
method shall be used, and such election shall remain in effect until a utility
request to effect a change is approved by the Commission. Each Gas Charge
shall be determined in accordance with Section 525.60.
b) The number and design of Gas Charge(s) applicable to a given
service may differ between services. For example, some services may include a
single Gas Charge while other services may include separate commodity and
non-commodity Gas Charges.
c) Utilities shall report monthly, in a format designated by the
Illinois Commerce Commission ("Commission"), the Gas Charge(s),
calculated under the provisions of Section 525.60 to be applied to service
rendered or billed during the effective month. The reports required by this
Section must be postmarked by the twentieth day of the filing month. A monthly
report postmarked after that date but prior to the first day of the effective
month will be accepted only if it corrects an error or errors from a timely
filed report for the same effective month. Any other report postmarked after
that date will be accepted only if submitted as a special permission request
under the provisions of Section 9-201(a) of the Public Utilities Act [220 ILCS
5/9-201(a)].
d) A utility shall reflect the requirements of this Part on the
first day of the utility's reconciliation year that begins on or after January
1, 1996. A utility implementing this Part after January 1, 1996, shall, from
January 1, 1996, until the first day of its reconciliation year, file all
tariffs pertaining to the utility's purchased gas adjustment clause in
conformance with Section 9-201 of the Public Utilities Act [220 ILCS 5/9-201].
