in accordance with Schedule B and Schedule C.

     

    Revenues

their respective number of transmission pole miles on the Transmission System.

    ANNUAL
TRANSMISSION REVENUE REQUIREMENTS RATIOS

     

    From time
to time the Coordinating Committee will calculate for each of the Companies its
Transmission Revenue Requirements Ratios set forth below. A Company’s
Transmission Revenue Requirements Ratio for revenue received under Part III of
the Open Access Transmission Tariff shall be a fraction, the numerator of which
is the Company’s transmission revenue requirement that is used to calculate the
Annual Transmission Revenue Requirements amount for the AEP West Zone – SPP set
forth on Attachment H to the Open Access Transmission Tariff (herein called the
Company Revenue Requirement) and the denominator of which is the sum of the
Company Revenue Requirement for all of the Companies. A Company’s Transmission
Revenue Requirement Ratio for revenue received under Part II of the Open Access
Transmission Tariff shall be a fraction, the numerator of which is the Company’s
transmission revenue
requirement that is used to calculate the Annual Transmission Revenue
Requirements underlying the rates set forth for the AEP West Zone – SPP on
Schedules 7 and 8 to the Open Access Transmission Tariff and the denominator of
which is the sum of the Company Revenue Requirements for all of the
Companies.
