GENERAL TERMS AND CONDITIONS (Cont'd)

 

45. ELECTRIC POWER COSTS ADJUSTMENT (EPCA)

 

45.1 Purpose. This Section provides for the recovery of electric power costs incurred by Transporter for

compression or processing of natural gas and for company use and operations (Electric Power Costs). Transporter

shall recover Electric Power Costs, including carrying charges calculated under Section 154.501 or successor

provision of the Commission's regulations, by means of a Transportation EPCA Rate, an LNG EPCA Rate and a

Processing EPCA Rate, each of which shall be comprised of a Current EPCA Rate and an EPCA Surcharge as

calculated in Section 45.4 below (hereinafter generally referred to as the "EPCA Rates"). The Transportation

EPCA Rate shall be applicable to Shippers under (i) Transporter's FTS, NTS, NTS-S, TPS, SST, GTS, OPT, and ITS

Rate Schedules as set forth in Volume No. 1 of this Tariff, and (ii) Rate Schedule X-124 and those X-Rate

Schedules set forth in Volume No. 2 of this Tariff that incorporate rates from Volume No. 1 of this Tariff

(collectively the Applicable Rate Schedules). The LNG EPCA Rate shall be applicable to Shippers under

Transporter's Rate Schedules X-131, X-132 and X-133. The Processing EPCA Rate shall be applicable to those

receiving processing services from Transporter. The EPCA Rates for recovery of Transporter's Electric Power

Costs are set forth at Sheet Nos. 25 through 30 and 31, inclusive, of this Tariff, which may be adjusted by

Transporter in subsequent Section 4(e) rate filings. Recovery of adjustments in such filings to the EPCA Rates

for the current period, and unrecovered amounts from preceding periods, shall be effected through the mechanism

set forth in this section.

 

45.2 Transporter's EPCA Filings. Annually, or at such other times as Transporter in its reasonable

discretion determines necessary, Transporter may adjust any of the EPCA Rates to take into account both

prospective changes in Electric Power Costs and unrecovered Electric Power Costs from the preceding period as

described at Section 45.4 below. That adjustment shall be effected by Transporter filing an Electric Power

Costs Adjustment (EPCA), with the Commission (i) annually on or before March 1 to become effective April 1

(Annual EPCA Filing), and (ii) at such other times as Transporter in its reasonable discretion determines

neccesary to become effective 30 days after filing (Periodic EPCA Filing).

 

45.3 Accounting for Activity. Transporter will account for all under or over recovered Electric Power Costs

for the three EPCA Rates in Account No. 186.

 

45.4 Adjustments to Electric Power Costs Recovery. Transporter's Electric Power Costs recovery through each

of its three EPCA Rates (Transportation, LNG or Processing), as adjusted by Transporter through its EPCA

filings, shall include the following components: (i) the current component of Transporter's Electric Power

Costs recovery for that particular EPCA Rate (the Current EPCA Rate), and (ii) the unrecovered component of

Transporter's Electric Power Costs recovery from the preceding period for that particular EPCA Rate (the EPCA

Surcharge). The Current EPCA Rate and the EPCA Surcharge for each of the three EPCA Rates shall be calculated

separately for EPCA filings in the following manner:

 

(a) Current EPCA Rate. In each Annual or Periodic EPCA Filing, Transporter shall calculate, and

allocate to the applicable Rate Schedules or services covered by that particular EPCA Rate on an as-billed basis

and in a manner consistent with Transporter's currently effective cost allocation and rate design, the Current

EPCA Rate by: (i) estimating the total Electric Power Costs for the 12-month period commencing with the

effective date of that EPCA Filing associated with the Rate Schedules or services covered by the particular EPCA

Rate, and (ii) dividing that amount by the applicable rate design determinants under all of the applicable Rate

Schedules or services covered by that particular EPCA Rate for that same 12-month period. The following is an

example of the calculation of the LNG Current EPCA Rate and the numbers are for illustrative purposes only:

 

Total Demand Capacity

 

Projected LNG Electric Power Costs $692,000 $ 138,400 $ 553,600

Projected Determinants 1,440,000 14,426,400

 

LNG Current EPCA Rate $0.100 $.038
