SPECIAL ARRANGEMENTS FOR SUBSTATION ALLOWANCES AND/OR TRANSMISSION VESTED
INTEREST (Continued)

Definitions (Continued)
Transmission Vested Interest Portion is that part of the Company’s transmission system in

Substation Allowance

If a Schedule 19 Customer’s request for service requires the installation of new or upgraded
transformer capacity in Substation Facilities, the following considerations will be included in the
separate agreement between the Customer and the Company:

The Customer will initially pay for the cost of new or upgraded Substation Facilities
required because of the Customer’s request. The Customer will be eligible to receive a one-
time Substation Allowance based upon subsequent sustained usage of capacity by the
Customer.

a. Substation Allowance: The maximum possible allowance will be
determined by multiplying the Customer’s actual increase in load by $69,397 per MW,
but will not exceed the actual cost of the Substation Facilities.

b. Substation Allowance Refunds: The Substation Allowance will be
refunded to the Customer over a five-year period, with annual payments based on the
Customer’s Basic Load Capacity at the time of refund. The first refund will be paid one
year following the first month energy is delivered through the new Substation Facilities.

The refunds will occur based on the following adjustment, which will be
added to the Substation Allowance received in the previous year. If there is no
change in load from the previous year, the Substation Allowance for that year is
equal to the Substation Allowance from the previous year:

((Change in load from the previous year as measured in MW) x (Substation Allowance per MW))
Number of Substation Allowance Refunds remaining in five-year period

The Customer’s annual refunds will be made in accordance with the
Substation Allowance amount stated in the separate construction agreement
between the Customer and the Company.

Transmission Vested Interest

If a Schedule 19 Customer’s request for service requires the installation of new or upgraded
capacity in Transmission Facilities, and those Transmission Facilities are serving the Customer by a
radial feed, the following considerations will be included in the separate agreement between the
Customer and the Company:
