ORDER NO. 28771

On May 25, 2001, Intermountain Gas Company (Intermountain; Company) filed an Application with the Idaho Public Utilities Commission for authority to place into effect new rate schedules that would result in an overall increase of approximately $27.1 million (12.9%) in revenues. Intermountain Gas supplies natural gas to approximately 200,000 customers in southern Idaho. In Order No. 28745, the Commission issued a Notice of Application, Modified Procedure and Comment Deadline. To allow additional time for public comment, the Commission suspended Intermountain Gas’ Application through July 13, 2001 and extended the comment deadline to July 2, 2001. Order No. 28752.
On July 2, 2001, Intermountain Gas filed an Amended Application seeking Commission authority to place into effect new rate schedules that would result in an overall increase of approximately $9.5 million (4.5%), rather than the $27.1 million (12.9%) requested in its original filing. To effectuate the proposed rates, the Company proposes to reduce the Weighted Average Cost of Gas (WACOG) to $0.35295 per therm. In light of the Amended Application, the Commission now extends the comment deadline to 12 p.m. (Noon) on Friday, July 6, 2001.
THE AMENDED APPLICATION
YOU ARE HEREBY NOTIFIED that the Amended Application’s proposed $9.5 million revenue increase reflects the elimination and/or imposition of a number of temporary gas and transportation cost adjustments, surcharges and credits. The Company’s filing also proposes to balance out its Purchased Gas Cost Adjustment (PGA), Account 186. The PGA Account is a deferral mechanism for over-and under-collections and for realized savings on spot market gas purchases.
YOU ARE FURTHER NOTIFIED that the Company alleges that their proposed rate change is necessitated by several factors, including: 1) a net decrease in costs from Intermountain’s natural gas interstate transportation, 2) an updated customer allocation of gas-related costs pursuant to the Company’s PGA provision, 3) the inclusion of temporary surcharges and credits for one year relating to gas and interstate transportation costs from Intermountain’s deferred gas cost account, and 4) a proposed decrease in the WACOG. The Company’s Application also seeks to eliminate the temporary surcharges and credits included in its current prices during the past twelve months, pursuant to Case No. INT-G-00-1. The net effect of these changes would result in an overall price increase to Intermountain’s RS-1, RS-2, GS-1, LV-1 and T-1 customers and a decrease to Intermountain’s T-2 customers.
YOU ARE FURTHER NOTIFIED that Intermountain Gas seeks to change the WACOG from $0.42296 per therm, which was approved by the Commission in Order No. 28578, to $0.35295. Intermountain Gas’ Amended Application states that this reduced WACOG would pass on lower producer prices to Intermountain customers.
YOU ARE FURTHER NOTIFIED that Intermountain Gas proposes to allocate deferred gas costs from its PGA Account No. 186 balance to its customers through a temporary price adjustment effective during the twelve-month period beginning July 1, 2001 and ending June 30, 2002. Since July 1, 2000, Intermountain Gas asserts that it has deferred variable gas costs estimated at $46,766,440 thus far in its PGA Account. The Company proposes to collect this amount via a per therm surcharge.
YOU ARE FURTHER NOTIFIED that the Company proposes to implement the following permanent change and temporary surcharge to its tariff rates for natural gas service and sales:
Permanent Adjustment:
INT-G-00-1 Elimination of Temporary Surcharges/Credits ($14,633,206)
Base Rate Change ($382,418)
Fixed Cost Collection ($1,852,579)
Temporary Surcharges or Credits:
Deferred Gas Costs (Intermountain Gas PGA Account 186)
Variable Cost Collection Adjustment ($262,530)
Uncollected Gas Costs $46,766,440
Market Segmentation ($2,377,070)
Fixed Gas Cost Misc. ($191,946)

YOU ARE FURTHER NOTIFIED that Intermountain’s Amended Application requests a total increase in annual revenue of $9.5 million or 4.5%. If approved, the Company estimates that residential customers (RS-1) using natural gas for space heating only could experience an average monthly billing increase of approximately $0.38 (1.68%). Residential customers (RS-2) using natural gas for both space and water heating could experience an average monthly increase of $3.30 (5.23%). Commercial customers (GS-1) could experience an average monthly increase of $10.57 (4.18%). Intermountain Gas recommends the following annualized change in rates per customer class:

Customer Class Revenue Proposed
Average Increase $ /Therm Proposed Average Increase % Change Proposed Average Price
$/Therm RS-1 Residential $591,173 $0.01602 1.68% $0.96759 RS-2 Residential $5,114,371 $0.04287 5.23% $0.86251 GS-1 General Service $2,964,973 $0.03260 4.18% $0.81325 LV-1 Large Volume * $482,189 $0.12512 23.47 $0.65813
* T-1 tariff price plus the Weighted Average Cost of Gas (WACOG) $0.35295

With the exception of the Industrial class, IGC proposes to allocate the change in rates to each of its customer classes in accordance with its Purchased Gas Cost Adjustment tariff and approved cost-of-service methodology. (Ref. Case Nos. INT-G-95-1, INT-G-88-2, U-1034-137). Because there are no fixed costs currently recovered in the tail block of Intermountain’s T-1 tariff and the proposed increase in the T-1 tariff is related to fixed costs (except for TF-1 commodity charge), a cents-per-therm increase is made only to the first two blocks of the T-1 tariff. All three blocks of Intermountain’s proposed T-1 tariff have been adjusted to include Williams Gas Pipelines-West firm transportation TF-1 commodity charge. The proposed increase in the T-2 tariff (except for TF-1 commodity charge) is related to fixed cost and, therefore, a cents per therm increase was made only to the T-2 demand charge. The commodity charge component of the T-2 tariff was adjusted to include Williams Gas Pipelines-West firm transportation TF-1 commodity charge.
YOU ARE FURTHER NOTIFIED that the Company’s Application to increase its rates is merely a proposal subject to public review and Commission approval.
YOU ARE FURTHER NOTIFIED that the Commission has jurisdiction over this matter and Intermountain Gas Company, a gas utility, pursuant to the authority and power granted under Title 61 of the Idaho Code and the Commission’s Rules of Procedure, IDAPA 31.01.01.000 et seq.
