Attorney for Alliance of Western Energy Consumers
BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF THE
INVESTIGATION INTO THE IMPACT
OF FEDERAL TAX CODE REVISIONS
ON UTILITY COSTS AND
RATEMAKING
CASE NO. GNR-U-18.01
STIPULATION AND SETTLEMENT
This Stipulation and Settlement ("Stipulation") is entered into by Intermountain Gas
Company (o'Intermountain Gas"), the Idaho Public Utility Commission's Staff ("Staff'), and the
Alliance of Westem Energy Consumers ("AWEC"), collectively referred to as the "Settling
Parties." The Settling Parties understand that this Stipulation is subject to approval by the Idaho
Public Utilities Commission ("IPUC" or "Commission").
I.INrnonuCTIoN
1. The terms and conditions of this Stipulation are set forth below. The Settling
Parties agree that this Stipulation represents a fair, just, and reasonable compromise of all the
issues raised in the proceeding, is in the public interest, and that its acceptance by the
ORIGINAL
STIPuLeuoN AND SETTLEMTNT, GNR-U-I8-OI . I
Commission represents a reasonable resolution of the issue identified by the Settling Parties in
this case. The Settling Parties, therefore, recommend that the Commission approve the
Stipulation and all of its terms and conditions without material change or condition.
II. BacrcnouND
2. On January 17,2018, the Commission issued Order No. 33965, which directed
each rate-regulated utility (besides small water companies with less than200 customers and
Atlanta Power) to file, among other things, revised tariffs that reflect changes in the federal
income tax code that resulted from the passage of the Tax Cuts and Jobs Act of 2017 ("2017 Tax
Law").
3. On March 23,2018,Intermountain Gas filed an Application that proposed new
rate schedules that would have decreased annualized revenues by $4,966,895.
4. In the Application, Intermountain Gas proposed that new rate schedules be
calculated using, as a base, the Company's recent 2016 General Rate Case as approved by the
Commission in Order No. 33879, adjusted for lower federal and state income taxes.
5. AWEC petitioned to intervene in this case on April25,2018 and this intervention
was not opposed by the Company. Though AWEC's intervention had not yet been granted,
AWEC participated in the settlement conference.
6. The Settling Parties participated in a settlement conference held in the
Commission offices on May 7,2018.
7. Intermountain Gas contended, and continues to contend, that the rate changes
proposed in its original Application are most appropriately used to calculate the changes caused
by the impact of revisions to the federal and state tax codes. However, recognizing the
procedural advantages of settlement, lntermountain Gas agrees to stipulate to settlement on the
SrpuLarIoN AND SETTLEMENT, GNR-U-18-01 - 2
terms contained in this Stipulation. As a compromise of the positions in this case, and for other
consideration as set forth below, the Settling Parties agree to the following terms:
III. TBnvIs
8. The Settling Parties agree to accept a Revenue Requirement Adjustment of
($5,111,303) to represent the benefit to the Company's customers caused by the revisions to the
federal and state tax codes.
9. The Settling Parties recognize that Attachment Nos. l-3 and Workpaper No. I to
this Stipulation replace Exhibit Nos. 1, 2,7 , and 8 and Workpaper No. 2 which were originally
filed with the Application, which have been adjusted to reflect the above ($5,1I1,303)
adjustrnent to the Company's revenue requirement.
10. The Settling Parties recommend acceptance of the proposed tariffs attached hereto
as Attachment No. 3.
I l. The Settling Parties also agree that the corresponding deferred liability on the
Company's books be measured by using these same tariffs and be passed back as a credit to the
Company's customers as part of the Company's next Purchased Gas Cost Adjustment ("PGA")
Application scheduled for later this year.
IV. GnNrnar, PRovrsrolrs
12. As set forth in this Stipulation, it is in good faith and the explicit intention of the
Settling Parties that the return of excess deferred income taxes to ratepayers resulting from the
reduction of corporate income tax rates is in full compliance of the IRS normalization
requirements. The Settling Parties also agree to the determination and amortization of all excess
deferred income taxes as presented in the Company's original Application.
SrpulerloN AND SErrLEMeNr. GNR-U-18-01 - 3
13. The Settling Parties agree that this Stipulation represents a compromise of the
positions of the Settling Parties in this case. As provided in Commission Rule 272, other than
any testimony or comments filed in support of the approval of this Stipulation, and except to the
extent necessary for a Settling Party to explain before the Commission its own statements and
positions with respect to the Stipulation, all statements made and positions taken in negotiations
relating to this Stipulation shall be confidential and will not be admissible in evidence in this or
any other proceeding.
14. The Settling Parties submit this Stipulation to the Commission and recommend
approval in its entirety pursuant to Commission Rule 274. Settling Parties shall support this
Stipulation before the Commission, and no Settling Party shall appeal a Commission Order
approving the Stipulation or an issue resolved by the Stipulation. If this Stipulation is challenged
by any person not a party to the Stipulation, the Settling Parties reserve the right to file
testimony, cross-examine witnesses, and put on such case as they deem appropriate to respond
fully to the issues presented, including the right to raise issues that are incorporated in the
settlement terms embodied in this Stipulation. Notwithstanding this reservation of rights, the
Settling Parties agree they will continue to support the Commission's adoption of the terms of
this Stipulation.
15. If the Commission rejects any part or all of this Stipulation or imposes any
additional material conditions on approval of this Stipulation, each Settling Party reserves the
right, upon written notice to the Commission and the other Parties to this proceeding, within 14
days of the date of such action by the Commission, to withdraw from this Stipulation. In such
case, no Settling Party shall be bound or prejudiced by the terms of this Stipulation, and each
Settling Party shall be entitled to seek reconsideration of the Commission's order, file testimony
SrIPur-RrroN eNo SsrrmuENr, GNR-U-18-01 - 4
as it chooses, cross-exarnine witnesses, and do all other things necessary to put on such case as it
deems appropriate.
16. The Settling Parties agree that this Stipulation is in the public interest and that all
of its terrns and conditions are fair, just and reasonable.
17 , No Settling Party shall be bound, benefited or prejudiced by any position asserted in
the negotiation of this Stipulation, except to the extent expressly stated herein, nor shall this
Sfipulation be consfued as a waiver of the rights of any Settling Party unless zuch rights are
expressly waived herein. Execution of this Stipulation shall not be deerned to constitute an
acknowledgernent by any Settling Party of the validity or invalidity of any particular method,
methodology, theory orprinciple of regulation or cost recovery. No Settling Party shall be deerned
to have agreed that any method, methodologry, tlr*ry, or principle of regulation or cost recovery
employed in arriving at this Stipulation is appropriate for resolving any issues in any other
proceeding in the future, No findings of fact or conclusions of law other than those stated herein
shall be deemed to be implicit in this Stipulation.
I 8. This Stipulation may be executed in courterparts and each signed counterpart shall
constitute an original document.
Dated: May 10,2018.
