Section 656.50  Recoverable Qualifying Infrastructure Plant Costs

 

QIP costs shall include the pre-tax return on QIP and the net depreciation expense applicable to QIP.

 

a)         The pre-tax return is calculated using the weighted cost of debt and weighted cost of equity determined in the utility's last rate case for the rate zone. The weighted cost of equity is multiplied by the gross revenue conversion factor (GRCF). The product is then added to the weighted cost of debt to obtain the pre-tax return. The pre-tax return is calculated using the following formulas:

 

 

 

Where:

 

GRCF	=	Gross Revenue Conversion Factor.
PPTRIT	=	Illinois Personal Property Tax Replacement Income Tax rate in effect at the time of the initial, annual or quarterly filing.
SIT	=	Illinois State income tax rate in effect at the time of the initial, annual or quarterly filing.
FIT	=	Federal income tax rate in effect at the time of the initial, annual or quarterly filing.
PTR	=	Pre-tax return.
WCCE	=	Weighted cost of common equity from the utility's last rate case for the rate zone.
WCPE	=	Weighted cost of preferred equity from the utility's last rate case for the rate zone.
WCLTD	=	Weighted cost of long term debt from the utility's last rate case for the rate zone.
WCSTD	=	Weighted cost of short term debt from the utility's last rate case for the rate zone.

 

b)         Net depreciation expense shall be calculated by applying the utility's approved depreciation rate to each category of QIP. The depreciation expense for QIP shall be reduced by the depreciation expense on the plant being replaced.

Section 656.60  Determination of the Qualifying Infrastructure Plant Surcharge Percentage

 

a)         The QIP surcharge percentage shall be expressed as a percentage carried to two decimal places. The QIP surcharge percentage shall be applied to the total amount billed to each customer located in the same rate zone based on the utility's otherwise applicable rates and charges. The QIP surcharge percentage shall not be applied to the exclusions listed in Section 656.30(a).

 

b)         In calculating the QIP surcharge percentage, the utility may choose either annual prospective operation or quarterly historical operation based on QIP investment data for a prior three-month period. Annual prospective operation may be selected only if the utility's immediately preceding rate case for the rate zone utilized a future test year as defined in 83 Ill. Adm. Code 287 and the utility submits the information required by Section 656.70(d)(7).

 

1)         Annual Prospective Operation

Utilities choosing annual prospective operation shall determine the QIP surcharge percentage for the operation year using the following formula:

 

S%	=	((NetQIP + AdjNetQIP) x PTR) + (Net Dep + AdjNetDep) + (R x 1.33) + ((O + INT) x Om)	x 100%
		PAR

 

Where:

 

S%	=	QIP surcharge percentage.
NetQIP	=	The average forecasted cost of the investment in QIP for the rate zone for the operation year less forecasted accumulated depreciation and accumulated deferred income taxes (ADIT) in QIP for the rate zone for the operation year. The average forecasted cost of QIP, net of depreciation and any ADIT liabilities (net of deferred tax assets) resulting from the QIP, shall be computed by using an average of 13 end-of-month balances of QIP, less accumulated depreciation and ADIT for the period from December 31 of the year preceding the operation year through December 31 of the operation year.
AdjNetQIP	=	The actual amount of netQIP as of the end of the QIP forecast period used in the utility's last rate case for the rate zone less the amount of NetQIP the Commission approved to be added to the utility's rate base as of the end of the QIP forecast period.
PTR	=	Pre-tax return as described in Section 656.50(a)(1).
Net Dep	=	Net depreciation expenses related to the average investment in QIP for the rate zone for the operation year. Depreciation expenses shall be calculated by multiplying the average forecasted cost of the investment in QIP by plant account, net of retirements, by the approved depreciation rates for the respective accounts in which the specific items included in the average QIP investment are recorded. The average forecasted cost of the investment in QIP by plant account, net of retirements, shall be computed by using an average of 13 end-of-the-month balances of QIP by plant account and retirements for the period from December 31 of the year preceding the operation year through December 31 of the operation year.
AdjNetDep	=	The actual amount of NetDep applicable to the QIP forecast period used in the utility's last rate case for the rate zone less the amount of NetDep that the Commission approved for the QIP forecast period used in the utility's last rate case for the rate zone.
R	=	Utility-determined reconciliation component (R component) calculated for the reconciliation year under the reconciliation feature as described in Section 656.80(d). The reconciliation component shall be collected over nine months from April through December.
O	=	The Commission-ordered adjustment component (O component).
INT	=	The calculated interest attributable to the O component. This interest shall be calculated as described in Section 656.80(i).
Om	=	The Commission-ordered O component multiplier. Om is a timing factor applied to the O component and the INT to allow for the collection of the O component and the INT over the remainder of the operation year.  For example, if the O component and the INT were included in the QIP surcharge percentage on January 1, the Om would be 1.00. Similarly, if the O component and the INT were included in the QIP surcharge percentage on April 1, the Om would be 1.33.
PAR	=	The projected total water or sewer QIP base rate revenues, as applicable, for the rate zone for the period from January 1 through December 31. The projected revenue shall not include the exclusions listed in Section 656.30(a).

 

Following the final order in each rate case, and before the Effective Month that will initiate the inclusion of AdjNetQIP and AdjNetDep, the utility shall file a public document in the rate case that provides the calculation of AdjNetQIP and AdjNetDep, including each component used to determine AdjNetQIP and AdjNetDep.

 

2)         Quarterly Historical Operation

Utilities choosing quarterly historical operation shall determine the QIP surcharge percentage for the quarter using the following formula:

 

S%	=	((NetQIP + AdjNetQIP) x PTR x .25) + (NetDep + AdjNetDep) + (R x .33) + ((O + INT) x Om)	x 100%
		PQR

 

Where:

 

S%	=	QIP surcharge percentage.
NetQIP	=	Original cost of QIP less accumulated depreciation and any accumulated deferred income tax (ADIT) liabilities net of deferred tax assets resulting from the QIP for the rate zone. NetQIP shall be the level of investment in QIP existing at the end of the calendar month in which an investment sheet is filed, net of depreciation and any ADIT liabilities (net of deferred tax assets) resulting from the QIP.
AdjNetQIP	=	The actual amount of NetQIP as of the end of the QIP forecast period used in the utility's last rate case for the rate zone less the amount of NetQIP the Commission approved to be added to the utility's rate base as of the end of the QIP forecast period.
PTR	=	Pre-tax return as described in Section 656.50(a)(1).
NetDep	=	Net quarterly depreciation expense applicable to NetQIP less the quarterly depreciation applicable to the plant being retired.
AdjNetDep	=	The actual amount of NetDep applicable to the QIP forecast period used in the utility's last rate case for the rate zone less the amount of NetDep that the Commission approved for the QIP forecast period used in the utility's last rate case for the rate zone.
R	=	Utility-determined reconciliation component calculated for the reconciliation year under the reconciliation feature as described in Section 656.80(d). The reconciliation component shall be collected over nine months from April through December. No reconciliation component amount shall be included for the January through March quarter.
O	=	Commission-ordered adjustment component.
INT	=	The calculated interest attributable to the O component. This interest shall be calculated as described in Section 656.80(i).
Om	=	The Commission-ordered O component multiplier. Om is a timing factor applied to the O component and the INT to allow for the collection of the O component and the INT over the remainder of the operation year.  For example, if the O component and the INT were included in the QIP surcharge percentage on January 1, the Om would be 0.25. Similarly, if the O component and the INT were included in the QIP surcharge percentage on April 1, the Om would be .33.
PQR	=	Projected quarterly water or sewer QIP base rate revenues, as applicable, for the rate zone during the calendar quarter when the QIP surcharge percentage shall be in effect. The projected quarterly revenue shall not include the exclusions listed in Section 656.30(a).

 

Following the final order in each rate case, and before the Effective Month that will initiate the inclusion of AdjNetQIP and AdjNetDep, the utility shall file a public document in the rate case that provides the calculation of AdjNetQIP and AdjNetDep, including each component used to determine AdjNetQIP and AdjNetDep.

Section 656.70  Rider and Information Sheet Filings

 

a)         A utility shall file a proposed QIP surcharge rider consistent with this Part pursuant to Section 9-201 of the Act. After a QIP surcharge rider is in effect, the QIP surcharge percentage shall be filed on an information sheet with supporting data no later than the 20^th day of the month preceding the effective date of the QIP surcharge percentage. An information sheet with supporting data filed after that date, but prior to the effective date, shall be accepted only if it corrects an error or errors from a timely filed information sheet for the same effective date. Any other information sheet with supporting data shall be accepted only if submitted as a special permission request to become effective on less than 45 days notice under the provisions of Section 9-201(a) of the Act.

 

b)         For utilities electing annual prospective operation, a utility may file its initial information sheet with a QIP surcharge percentage for the initial operation year with an effective date of the first day of any month.  The effective date of any subsequent information sheet with a QIP surcharge percentage is January 1 (and April 1 if the R component is modified). A utility may, at its option, file an information sheet modifying the QIP surcharge percentage, with an effective date of the first day of any month during the operation year, when necessary to recognize a material change in assumptions used in developing the QIP surcharge percentage (including, but not limited to, a change in depreciation rates). The utility shall also file an information sheet to implement a Commission-ordered O component.

 

c)         For utilities electing quarterly historical operation, a new QIP surcharge percentage may become effective on April 1, July 1, October 1, and January 1 (with a new R component becoming effective, if required, on April 1). A utility may elect not to file an information sheet showing an increased QIP surcharge percentage for any quarter provided that the QIP costs that would have been reflected for that quarter are in excess of the level reflected in developing the QIP surcharge percentage in effect for the quarter are disregarded in calculating the R component and O component for the affected reconciliation year.

 

d)         A utility electing annual prospective operation shall provide the following with the filing of each information sheet to become effective on January 1:

 

1)         A calculation of the QIP surcharge percentage, PTR, and GRCF for each rate zone for which a QIP surcharge rider is in effect;

Section 656.80  Annual Reconciliation

 

a)         On or before March 15 of each year, a utility that had a QIP surcharge in effect for all or part of the immediately preceding calendar year shall submit to the Commission an annual reconciliation regarding the results for the previous reconciliation year. The annual reconciliation shall include testimony and schedules that support the accuracy and the prudence of the qualifying infrastructure investment for the reconciliation year, and shall be verified by an officer of the utility.  The schedules included with the annual reconciliation shall reflect all carry forward adjustments from prior QIP surcharge reconciliation Orders, and the testimony shall address how adjustments ordered in prior QIP surcharge reconciliations are reflected in the current reconciliation.  As required by this Section, the annual reconciliation shall include a calculation of the R component necessary to adjust revenue collected under the QIP surcharge rider in effect for the rate zone during the reconciliation year to an amount equivalent to the actual level of prudently-incurred QIP cost for the reconciliation year. In the event that the earnings report filed under this Section for the rate zone shows that the utility's actual rate of return has exceeded the level authorized in the utility's last water or sewer general rate proceeding for the rate zone, as applicable, then the R component shall include the credit required by subsections (c) and (d). Any adjustment made through the R component shall be in effect for nine months commencing on the April 1 immediately following submittal of the annual reconciliation.

 

b)         With the annual reconciliation, the utility shall file a petition seeking initiation of the annual reconciliation hearings required by Section 9-220.2 of the Act. After the hearing, the Commission shall determine the amount of the adjustment, if any, that should be made (through the O component) to the level of revenue collected by operation of the QIP surcharge rider during the reconciliation year, so that the amount of such revenue is equal to the actual level of prudently-incurred QIP cost for the reconciliation year (to the extent that such adjustment has not already been reflected through an adjustment made by the utility to the R component of the QIP surcharge percentage).

 

c)         In the annual reconciliation, the utility shall include, for each rate zone in which a QIP surcharge has been in effect, data showing operating income and rate base for the reconciliation year, the data being developed in accordance with subsection (f)(4). If, for any such rate zone, the actual rate of return on rate base for the reconciliation year exceeds the overall rate of return allowed in the utility's last water or sewer general rate proceeding for the rate zone, revenues collected under the QIP surcharge rider shall be reflected as a credit through the R component of the QIP surcharge to the extent that such revenues contributed to the realization of a rate of return above the last approved level. A credit value for the R component will result in a reduction of the QIP surcharge percentage. To the extent, if any, that a required adjustment for a reconciliation year has not been already made by the utility (through the R component), the Commission shall require (through the O component) that such an adjustment be made after the annual reconciliation hearing.

 

d)         Utilities shall calculate the R component using the following formula:

 

R

=

((ActNetQIP + AdjNetQIP) x PTR) + (ActNetDep + AdjNetDep) - QIPRev + Rpy + Opy - EEA

 

Where:

 

R	=	Utility-determined reconciliation component.
ActNetQIP	=	The average actual cost of the investment in QIP for the rate zone for the reconciliation year less actual accumulated depreciation and any accumulated deferred income tax (ADIT) liabilities net of deferred tax assets resulting from the QIP for the rate zone for the reconciliation year. The average actual cost of QIP, net of depreciation and ADIT, shall be computed by using an average of 13 end-of-month balances of QIP less accumulated depreciation and associated ADIT for the period from December 31 of the year preceding the reconciliation year through December 31 of the reconciliation year. (For utilities electing quarterly historical operation, the amount of the ActNetQIP shall be limited by the provisions of Section 656.70(c).)
AdjNetQIP	=	AdjNetQIP as defined in Section 656.60. The effective date of the AdjNetQIP will be as disclosed in the document required following a rate case as described in Section 656.60.
PTR	=	Pre-tax return as described in Section 656.50(a)(1).
ActNetDep	=	Actual net depreciation expense related to the average investment in QIP for the rate zone for the reconciliation year. Depreciation expense shall be calculated by multiplying the actual investment in QIP by plant account,
		net of retirements, by the approved depreciation rates for the respective accounts in which the specific items included in the average QIP investment are recorded. (For utilities electing quarterly historical operation, the amount of the ActNetDep shall be limited by the provisions of Section 656.70(c).)
AdjNetDep	=	AdjNetDep as defined in Section 656.60. The effective date of the AdjNetDep will be as disclosed in the document required following a rate case as described in Section 656.60.
QIPRev	=	Actual QIP revenues collected during the reconciliation year through the QIP surcharge.
Rpy	=	The R component from the previous reconciliation year.
Opy	=	The sum of the O component and the calculated interest attributable to the O component, or the sum of any O components and the calculated interest attributable to the O components included in the calculation of the QIP surcharge percentage during the reconciliation year.
EEA	=	Excess earnings amount calculated in accordance with subsections (a), (c) and (f)(4). There will only be an EEA when the utility's actual rate of return for the reconciliation year exceeds the overall rate of return authorized by the Commission in the utility's last water or sewer rate proceeding for the rate zone.

 

e)         Any adjustment made by Order of the Commission under subsection (b) or (c) shall be included in the O component and be in effect for either 12 months or 9 months, beginning on the next January 1 (if 12 months) or April 1 (if 9 months) following the Order of the Commission, or such other period as the Commission may direct in the Order requiring that an adjustment be made.

 

f)         Each annual reconciliation shall include the following schedules:

 

1)         A schedule showing, for each rate zone for which a QIP surcharge rider was in effect, the QIP costs for the reconciliation year;

 

2)         A schedule showing, for each rate zone for which a QIP surcharge rider was in effect, the revenues arising through the application of the QIP surcharge during the reconciliation year;

 

3)         A schedule showing, for each rate zone for which a QIP surcharge rider was in effect, the reconciliation component determined by the utility showing the amount to be recovered or refunded over a nine-month period commencing on April 1; and

 

4)         Schedules showing the utility's calculation of actual operating income and 13-month average rate base for the reconciliation year by rate zone. This calculation of actual operating income and 13-month average rate base shall be adjusted for any applicable adjustments accepted by the Commission in the utility's last rate case for the rate zone. In calculating the amount of federal and State income tax expense reflected in operating income, the utility shall reflect as deductible interest expense for tax purposes the product that results when the weighted embedded cost-of-debt reflected in the overall rate of return calculation used in the utility's last rate proceeding for the rate zone is multiplied by the rate base for the applicable rate zone as shown in the annual reconciliation. In the event that the actual rate of return for any rate zone exceeds the rate of return allowed in the utility's last water or sewer general rate proceeding for the rate zone, a schedule showing the extent to which revenues provided by operation of the QIP surcharge contributed to the difference between the actual and last-authorized rate of return also shall be provided. The amount of the revenues provided by the QIP surcharge that contributed to the actual rate of return exceeding the overall rate of return authorized by the Commission in the utility's last water or sewer rate proceeding for the rate zone shall be included as a credit in the calculation of the R component.

 

g)         The first reconciliation year shall begin on the effective date of the first QIP surcharge information sheet and end on December 31 of the calendar year in which the first information sheet became effective. Each subsequent reconciliation year shall end on December 31.

 

h)         When the utility files its annual reconciliation, the utility shall provide copies of the following items to the Commission's Manager of the Water Department and to the Commission's Manager of the Accounting Department:

 

1)         Copies of all workpapers pertaining to the reconciliation;

 

2)         A detailed summary of all invoices supporting the costs for eligible QIP surcharge projects;

 

3)         Copies of the applicable general ledger or comparable material supporting the recovery of the QIP surcharge;

 

4)         A detailed worksheet showing the calculation of any utility-determined reconciliation component (R component) amount based upon the annual reconciliation; and

 

5)         Information regarding the prudence of the utility's investment in QIP.

 

i)          Amounts either collected or refunded through the O component shall accrue interest at the rate established by the Commission under 83 Ill. Adm. Code 280.40(g)(1). Interest on the O component shall be applied from the end of the reconciliation year until the O component is refunded or charged to ratepayers through the QIP surcharge.
