GENERAL TERMS AND CONDITIONS (Continued)

38. FUEL AND ELECTRIC POWER REIMBURSEMENT ADJUSTMENT PROVISION (Continued)

38.5 Electric Power Reimbursement Current Rate:

38.5.1 The Electric Power Reimbursement Current Rate applicable

to gathering, storage and/or transportation service rendered shall

reflect the projected level of Transporter's system average cost

of electric power reimbursement per unit of relevant service

during the period the adjustment is to be in effect as specified

in Subsection 38.5.2 hereof.

38.5.2 The Electric Power Reimbursement Current Rate per unit

of gathering, storage and/or transportation service to be

recovered by Transporter during the six (6) month effective period

shall be calculated by dividing the projected total gathering,

storage and/or transportation function electric power costs, as

applicable, by the total Projected Quantities (i.e., Gathering

receipts, Storage injection and/or withdrawals or Transportation

receipts), as applicable, for the effective period.

38.5.2.1 The Electric Power Reimbursement Current Rate

per unit of contract storage service shall be determined by

first apportioning Transporter's projected storage cost of

electric power (Storage Electric Power Cost) for the

effective period to contract storage service (i.e.,

injections and/or withdrawals under Rate Schedules FS-1 and

IS-1) based on the ratio of the sum of projected contract

storage injections and/or withdrawals (Projected Contract

Storage Quantities) to the total of the projected system

storage (i.e., Transporter's storage injections and/or

withdrawals for maintenance of balancing and line pack) and

Projected Contract Storage Quantities. The Electric Power

Reimbursement Current Percentage per unit of contract

storage service shall then be calculated by dividing the

Storage Electric Power Cost apportioned to the contract

storage service by the applicable Projected Contract Storage

Quantities for the effective period to calculate the

Electric Power Reimbursement Current Rate-Storage.
