Appendix A: Annual Transmission Revenue Requirement for Schedule 19 and Schedule 10 Projects

General Note: References to pages in this transmission formula rate rate are indicated as: (page#, line#, col.#)
References to data from FERC Form 1 are indicated as: #.y.x (page, line, column)

Notes

A All amounts shown are based on 13 month averages which monthly numbers are contained in footnotes to the FF1 (with the following exceptions: CWC in line 28, which is based upon one-eigth of
O&M,Accumulated Deferred Income Taxes in line 24 and Excess Accumulated Deferred Income Taxes in line 25, which are beginning/ending year averages and prorated amounts) .

B The maximum accumulated deferred tax offset to rate base is calculated in accordance with the proration formula prescribed by IRS regulation section 1.167(l)-1(h)(6).

C Cash Working Capital equals one-eighth (45 days) of O&M allocated to Schedule 19 or Schedule 10 Projects.

D Includes only FICA and unemployment taxes.

E Any transmission regulatory expenses allocated to Schedule 19 or Schedule 10 Projects are determined after deducting any directly assigned transmission regulatory expenses.

 

F

 

Below are the currently effective income tax rate, where FIT is the Federal income tax rate; SIT is the State income tax rate, and p = "the percentage of federal income tax deductible for state income taxes". If

the utility is taxed in more than one state it must attach a work paper showing the name of each state and how the blended or composite SIT was developed. Furthermore, a utility that elected to utilize

amortization of tax credits against taxable income, rather than book tax credits to Account No. 255 and reduce rate base, must reduce its income tax expense by the amount of the Amortized Investment Tax

Credit (Form 1, 266.8.f) multiplied by (1/1-T). Any Excess or Deficient Deferred Income Taxes reduce or increase income tax expense by the amount of the expense multiplied by (1/1-T).

Inputs Required: FIT = 0.00%

SIT= 0.00% (State Income Tax Rate or Composite SIT)

 p = 0.00% (percent of federal income tax deductible for state purposes)
G Include ATU for Year N with Projected ATRR for Year N+2

H Debt cost rate = long-term interest / long term debt. Preferred cost rate = preferred dividends / preferred outstanding. For Schedule 19 Projects, the ROE is determined by the New York Public Utilities
Commission and capped by the ROE determined by FERC. The ROE Cap will be supported in the original filing and no change in ROE Cap may be made absent a filing with FERC. For Schedule 10 Projects,
the ROE will be supported in the original filing and no change in ROE Cap may be made absent a filing with FERC.

 I Includes revenue related to Schedule 19 Projects or Schedule 10 Projects only, such as pole attachments, rentals and special use.
J Includes revenue related to Schedule 19 Projects or Schedule 10 Projects only.

K The following acronyms are used for allocators:

CP= common plant allocator (allocate common plant and common expenses to total electric) DA= direct assignment (the item is direct assigned to Schedule 19 Projects)

 GP19 or GP10= gross plant allocator (allocated Schedule 19 Projects or Schedule 10 Projects gross plant as % of electric and common plant)
GPE 19 ot GPE 10= gross electric plant allocator (allocated Schedule 19 Projects or Schedule 10 Projects gross plant as % of total electric gross plant)
S19P or S10P= Schedule 19 Projects or Schedule 10 Projects plant allocator (Schedule 19 Projects or Schedule 10 Projects gross plant as % of total transmission gross plant)

 Schedule 19 Projects or Schedule 10 Projects wage and salary allocator (Schedule 19 Projects or Schedule 10 Projects wages and salaries as % of total electric
S19 W/S or S10 W/S= wages and salaries)

Schedule 19 Projects or Schedule 10 Projects wages and salary allocator for transmission (Schedule 19 Projects or Schedule 10 Projects wages and salaries as S19 W/S T or S10 W/S T a % of transmission wages and salaries)

NA= not applicable (the item is not applicable to Schedule 19 Projects or Scheduel 10 Projects) T W/S= transmission wages and salaries as % of electric wages and salaries

L Con Edison will exclude items in Account 930.2 shown on FF1 page 335 that are greater than $1 M and not directly or indirectly related to the provision of transmission services.

 Con Edison either will direct assign O&M expense that have been tracked for the Schedule 19 Projects or Schedule 10 Projects or allocate transmission O&M to the Schedule 19 Projects or Schedule 10 Projects,
M but not both.

N In accordance with the NYISO OATT, Section 14.1.5, the gross receipts tax included in the ATRR for Schedule 19 and Schedule 10 Projects is as follows:
Schedule 19 Schedule 10

 Gross receipt tax rate 0.00000% 0.00000%
Revenue requirement - - Gross Receipts Tax - -

O The impact of an additional 25 basis points for the ROE on projects resulting from the NYISO's Public Policy Transmission Planning Process under Attachment Y.
P By project ATRRs are on Workpaper 10a for Schedule 19 Projects and Workpaper 10b for Schedule 10 Projects.
Q Schedule 19 projects are not eligible for any ROE incentive adders.

R For future use

 Note A: The calculations of ADIT amounts resulting from liberalized depreciations are performed in accordance with the proration requirements of Treasury Regulation Section 1.167(l)-1(h)(6).
Differences attributable to over-projection of ADIT in the annual projection will result in a proportionate reversal of the projected prorated ADIT activity to the extent of the over-projection.
Differences attributable to under-projection of ADIT in the annual projection will result in an adjustment to the projected prorated ADIT activity by the difference between the projected monthly activity
and the actual monthly activity. However, when projected monthly ADIT activity is an increase and actual monthly ADIT activity is a decrease, actual monthly ADIT activity will be used.
Likewise, when projected monthly ADIT activity is a decrease and actual monthly ADIT activity is an increase, actual monthly ADIT activity will be used.

Workpaper 7a19: Annual True-up Adjustment (Schedule 19 Projects)
Actual or Projected for the 12 Months Ended December ….
Schedule 19

Debit amounts are shown as positive and credit amounts are shown as negative.

The Annual True-Up Adjustment ("ATU") component of the Formula Rate for each Year shall be determined as follows:

(i) In accordance with its formula rate protocols, Con Edison shall recalculate its Annual Transmission
Revenue Requirement ("ATRR") for the previous calendar year based on its actual costs as reflected in its Form No. 1 and its
books and records for that calendar year, consistent with FERC accounting policies.

(ii) Determine the difference between the Actual ATRR as determined in paragraph (i) above,
and actual revenues based upon the Projected ATRR for the previous calendar year

(iii) Multiply the ATRR Before Interest by (1+i)^24 months

Where: i = Average of the monthly rates from the middle of the Rate Year for which the ATU
is being calculated through the middle of the year in which the ATU is included in rates (24 months)
The interest rates are initially estimated and then trued-up to actual

 To the extent possible each input to the Formula Rate used to calculate the Actual ATRR
will be taken directly from the FERC Form No. 1 or will be reconcilable to the FERC Form 1
by the application of clearly identified and supported information. If the reconciliation

is provided through a Workpaper included in the filed Formula Rate Template, the inputs to the Workpaper must meet this
transparency standard, and doing so will satisfy this transparency requirement for the amounts that are output from the
Workpaper and input to the main body of the Formula Rate.

Notes:

A The interest rate on corrections will be the average monthly FERC interest rate for the period from the beginning of the year being
corrected through the end of the rate year where the correction is reflected in rates - the same as how interest on the Annual True-
up Adjustment is computed.

B The number of months in which interest is computed is from the middle of the rate year in which the correction is needed to the
middle of the rate year where the correction is reflected in rates - the same as how interest on the Annual True-up Adjustment is
computed.

C Con Edison will provide revised formula rate calculations to support any corrections.
