DR 98-161 Northern Utilities, Inc. 1998/1999 Winter Cost of Gas Adjustment Order Approving Cost of Gas Adjustment O R D E R N O. 23,053 October 30, 1998 APPEARANCES: LeBoeuf, Lamb, Greene, and MacRae by Meabh Purcell, Esq. on behalf of Northern Utilities, Inc.; and Robert Egan and Stephen P. Frink for the Staff of the New Hampshire Public Utilities Commission. I. PROCEDURAL HISTORY On September 15, 1998, Northern Utilities, Inc. (Northern) filed with the New Hampshire Public Utilities Commission (Commission) its Cost of Gas Adjustment (CGA) for the period November 1, 1998 through April 30, 1999 for effect November 1, 1998 in Northern's natural gas operations in the Seacoast area of New Hampshire. The filing was accompanied by the pre-filed direct testimony and supporting attachments of Marjorie H. Izzo, Senior Rate Analyst, and Francisco C. DaFonte, Director of Gas Control, which explained the filing. An Order of Notice was issued on September 22, 1998 setting the date of the hearing for October 22, 1998 at 10:30 a.m. at the Commission's office in Concord, New Hampshire. Apart from the Office of Consumer Advocate (OCA) which is a statutorily recognized intervenor, there were no intervenors in this docket. A duly noticed hearing on the merits was held at the Commission on October 22, 1998. At the hearing, Northern filed a revised proposed CGA rate, a credit of $0.0323 per therm. II. POSITIONS OF THE PARTIES AND STAFF Northern Northern witnesses Marjorie H. Izzo, Senior Rate Analyst, Francisco C. DaFonte, Director of Gas Control, and Joseph A. Ferro, Director of Pricing Services, addressed the following issues: a) calculation of the CGA and the impact on customer bills; b) factors contributing to the decreased rate; c) changes in the supply portfolio and rate impact; d) environmental remediation surcharge; and e) elimination of the trigger mechanism. A. Calculation and Rate Impact of the proposed CGA The proposed 1998/1999 Winter CGA credit of $0.0323 per therm was calculated by reducing the anticipated cost of gas of $15,223,765 for net adjustments of ($2,224,090) and dividing the resulting anticipated cost of $12,999,675 by projected therm sales of 36,901,214 and deducting the base winter cost of gas of $0.3846 per therm. Northern's proposed 1998/1999 Winter CGA is a credit of $0.0323 per therm, representing a decrease of $0.0576 per therm from the 1997/1998 winter CGA charge of $0.0253 per therm. The proposed CGA credit of $0.0323 will decrease an average residential heating customer's monthly bill by approximately $9, or 7 percent, compared to last winter's rate. B. Factors Contributing to the Decreased CGA The 6 cent reduction in the proposed CGA per therm price compared to last winter's rate can be almost solely attributed to the prior period over collection of $3,460,772 which is being applied against the 1998/1999 actual and projected winter gas costs. Northern's projected gas costs changed very little from the prior year's forecast, although the commodity cost of gas is substantially lower. Northern's demand charges and supplemental fuel costs offset the commodity savings. Northern has contracted for twenty years of pipeline capacity on the Portland Natural Gas Transmission System (PNGTS), effective on the PNGTS in-service date. Due to the uncertainty of that date, Northern purchased an option to continue the lease of the Portland Pipeline Corp. (Portland), a converted oil pipeline used to ship natural gas. The uncertainty of the PNGTS in-service date forced Northern to exercise that option, resulting in additional costs of approximately $1 million for Northern's New Hampshire customers. The Portland lease runs through April 30, 1999. Also included in the CGA calculation are capacity costs on PNGTS starting on January 1, 1999, the anticipated in-service date at the time of the filing. C. Changes in Supply Portfolio and Rate Impact During discovery, discussions with Staff led Northern to believe that the projected in-service date for PNGTS would not occur during the 1998/1999 winter period. Northern is in the process of redesigning its supply portfolio by eliminating the PNGTS capacity charges and purchasing additional supplemental supplies. Northern will provide Staff with the revised costs prior to December 1, 1998, and will calculate a revised CGA based on those costs. Northern does not anticipate a substantial change in the CGA rate and proposed addressing any projected over or under recovery through the monthly adjustment mechanism. If a material deviation does result, Northern will submit a revised CGA filing. D. Environmental Remediation Surcharge NHPUC Order 23,046 (October 27, 1998) approved a mechanism for recovery of environmental remediation costs associated with former manufactured gas plant sites, such costs to be filed during its winter CGA proceeding for review and, if approved, recovered over seven years. Northern filed for recovery of unamortized deferred environmental remediation costs of $517,095, incurred from December 1, 1992 through June 30, 1998. The proposed environmental surcharge of $0.0010 per therm was determined by dividing the annual expense of $73,871 by anticipated sales of 71,577,974 therms for the period of November 1, 1998 through October 31, 1999. E. Elimination of the Trigger Mechanism The "trigger mechanism" was implemented in 1985 and requires Northern to file a revised CGA if the actual and projected revenues and costs deviate by 10 percent or greater. Northern stated that the trigger mechanism was designed to prevent the carry forward of substantial over or under recoveries from one CGA period to the next. Northern believes that it now has the tools to effectively control over and under recoveries and that the trigger mechanism is no longer necessary. Northern stated that with implementation of the monthly adjustment mechanism, approved in NHPUC Order 22,917 (April 30, 1998), Northern is now able to better control over and under collections and the trigger mechanism is no longer needed. Staff Staff stated that after a review of the filing and subsequent discovery, Staff believes Northern's gas purchasing policies are sound and reasonable and that the proposed 1998/1999 winter CGA credit of $0.0323 per therm should be approved. Staff also recommended, after having reviewed the environmental remediation costs and supporting documentation submitted by Northern, that the Commission find that those costs were prudently incurred and should be recovered through the proposed surcharge. Staff recommended the elimination of the trigger mechanism, stating that it is Staff's belief that the tools are in place to effectively prevent large over or under recoveries. Staff did state that if a material over or under collection were projected, it would expect Northern to file a revised CGA. OCA While the OCA was unable to attend the hearing, the OCA asked Staff to represent its support for the elimination of the trigger mechanism based on the above stated reasons. III. REPORT OF THE HEARINGS EXAMINER The Hearings Examiner reviewed the filing and supporting testimony presented at the October 22, 1998 hearing and has stated that the CGA rate and the request to institute the Environmental Remediation Cost (ERC) rate coincident with the CGA rate appear to be reasonable based on Staff and Northern's representations. IV. COMMISSION ANALYSIS We have reviewed the filing, testimony and the Report of the Hearings Examiner and agree that the proposed revised 1998/1999 Winter CGA credit of $0.0323 per therm and the ERC surcharge of $0.0010 per therm will result in just and reasonable rates and is hereby approved. With the new mechanism that allows Northern to make monthly adjustments to its CGA rate in response to projected over or under recoveries, it is our belief that the 10% trigger mechanism is no longer needed. Accordingly, we approve the elimination of the trigger mechanism as recommended by Staff and supported by Northern and the OCA. Based upon the foregoing, it is hereby ORDERED, that Northern's Twenty-sixth Revised Page 32, Sheet No. 1 and Proposed Twentieth Revised Page 32, Sheet No. 2, respectively, N.H.P.U.C. tariff of Northern Utilities, Inc. - New Hampshire Division, providing for a Winter CGA credit of $0.0323 per therm for the period of November 1, 1998 through April 30, 1999, is approved, effective for bills rendered on or after November 1, 1998; and it is FURTHER ORDERED, that Northern may adjust the approved CGA rate of ($0.0323) per therm upward or downward monthly based on Northern's calculation of the projected over or under collection for the period, but the cumulative adjustments shall not exceed ten percent (10%) of the approved unit cost of gas of $0.3523 per therm (or $0.0352 per therm); and it is FURTHER ORDERED, that Northern will provide the Commission with its monthly calculation of the projected over or under calculation, along with the resulting revised CGA rate for the subsequent month, not less than five (5) business days prior to the first day of the subsequent month. Northern shall include a revised tariff page 32 - Calculation of Cost of Gas Adjustment and revised rate schedules if Northern elects to adjust the CGA rate; and it is FURTHER ORDERED, that the over or under collection shall accrue interest at the Prime Rate reported in the Wall Street Journal. The rate is to be adjusted each quarter using the rate reported on the first date of the month preceding the first month of the quarter; and it is FURTHER ORDERED, that Northern's Second Revised Page 35 Superseding First Revised Page 35, providing for a surcharge of $0.0010 per therm to recover the cost of environmental remediation and pursuit of third party claims related to former manufactured gas plants, is approved, effective for bills rendered on or after November 1, 1998; and it is FURTHER ORDERED, that Northern shall file properly annotated tariff pages in compliance with this Order no later than 15 days from the issuance date of this Order, as required by N.H. Admin. Rules, Puc 1603. By order of the Public Utilities Commission of New Hampshire this thirtieth day of October, 1998. Douglas L. Patch Susan S.
