83 Ill. Adm. Code 525.40
Recoverable Gas Costs
Section 525
Section 525.40 Recoverable
Gas Costs
a) Costs recoverable through the Gas Charge(s) shall include the
following:
1) costs of natural gas and any solid, liquid or gaseous
hydrocarbons purchased for injection into the gas stream or purchased as
feedstock or fuel for the manufacture of gas, or delivered under exchange
agreements;
2) costs for storage services purchased;
3) transportation costs related to such natural gas and any
solid, liquid or gaseous hydrocarbons and any storage services; and
4) other out-of-pocket direct non-commodity costs, related to
hydrocarbon procurement, transportation, supply management, or price
management, net of any associated proceeds, and Federal Energy Regulatory
Commission-approved charges required by pipeline suppliers to access supplies
or services described in subsections (a)(1) through (3) of this Section.
b) Determinations of the Gas Charge(s) shall exclude the
estimated cost of gas to be used by the utility, based on the system average
cost of gas for the effective month.
c) The cost of gas estimated to be withdrawn from storage during
the base period shall be included in the Gas Charge(s).
d) Recoverable gas costs shall be offset by the revenues derived
from transactions at rates that are not subject to the Gas Charge(s) if any of
the associated costs are recoverable gas costs as prescribed by subsection (a)
of this Section. This subsection shall not apply to transactions subject to
rates contained in tariffs on file with the Commission, or in contracts entered
into pursuant to such tariffs, unless otherwise specifically provided for in
the tariff. Taking into account the level of additional recoverable gas costs
that must be incurred to engage in a given transaction, the utility shall
refrain from entering into any such transaction that would raise the Gas
Charge(s).
e) Revenues from penalty charges or imbalance charges, which the
Commission has previously approved to prevent unauthorized actions of
customers, shall offset gas costs.
f) Revenues from "cash-out" schedules, which the
Commission has previously approved for transportation customers' monthly
imbalances, shall offset gas costs. Under such schedules, the utility can
charge customers for gas used in excess of the amount contracted for, or can
refund to customers the avoided cost of gas not taken. Refunds by the utility
pursuant to any such "cash-out" schedule shall be treated as gas
costs recoverable under this Section.
