27. FUEL PERCENTAGES (continued)

27.4 For each Rate Schedule, the revised Fuel Percentages shall be

calculated as follows: (a) The revised Fuel Use and Storage Fuel

Use percentages shall be calculated on the basis of the difference

between (i) the actual Fuel Use or Storage Fuel Use usage during

the Base Period and (ii) the amount of Fuel Use (plus the amount

of Delhi Fuel Use for Rate Schedule PHS wheeling transactions

retained in-kind by Transporter during the Base Period) or Storage

Fuel Use retained in-kind by Transporter during the Base Period.

The difference shall be added to or subtracted from, as

appropriate, the actual Fuel Use or Storage Fuel Use usage during

the Base Period, and the total, expressed as a percentage of the

estimated applicable throughput for the Recovery Period (excluding

throughput through Delhi Compressor under the wheeling option of

Rate Schedule PHS and quantities delivered under transactions

described in Section 27.6 below), shall be the Fuel Use percentage

or the Storage Fuel Use percentage, as applicable, to be in effect

during the Recovery Period; and (b) The revised LUFG and Storage

LUFG percentages shall be calculated on the basis of the

difference between (i) the actual LUFG or Storage LUFG during the

Base Period and (ii) the amount of LUFG (plus the amount of

Wheeling LUFG for Rate Schedule PHS wheeling transactions retained

in-kind by Transporter during the Base Period) or Storage LUFG

retained in-kind by Transporter during the Base Period. The

difference shall be added to or subtracted from, as appropriate,

the actual LUFG or Storage LUFG during the Base Period, and the

total, expressed as a percentage of the estimated applicable

throughput for the Recovery Period (excluding quantities delivered

under wheeling transactions pursuant to Rate Schedule PHS), shall

be the LUFG percentage or the Storage LUFG percentage, as

applicable, to be in effect during the Recovery Period.

Throughput associated with Line CP, Line J Backhauls, the Sligo

Lease and Alternate Fuel Retentions shall be excluded from the
