DOCKET NO. 2013-00133

 

December 5, 2013

NORTHERN UTILITIES, INC. d/b/a UNITIL,

Proposed Increase In Rates

   STIPULATION

Northern Utilities, Inc., d/b/a Unitil (“Company”) and the Maine Office of Public Advocate (“OPA”), collectively the “Parties”, hereby agree and stipulate as follows:

I. PURPOSE

The purpose of this Stipulation is to resolve all issues in Docket No. 2013-00133, as further specified in Section III below. The provisions agreed to in this Stipulation have been reached as a result of information filed in this proceeding, obtained through discovery, meetings and Technical Conferences, and from discussions and negotiations among the Parties in this case. The Parties agree that they will work together to obtain Commission approval of the terms of the Stipulation in the public interest.

II. PROCEDURAL HISTORY

The Company submitted its Notice of Intent to File a General Rate Case in Docket No. 2013-00133 on February 1, 2013, in accordance with Section 6, Chapter 120 of the Maine Public Utilities Commission’s (“the Commission”) rules. On February 21, 2013, the OPA filed its Petition to Intervene as a party in the proceeding.

On April 1, 2013, the Company submitted its initial filing in Docket No. 2013-00133, including Direct Testimony and studies sponsored by Mark H. Collin, Thomas P. Meissner, Jr., David L. Chong, George E. Long, Paul M. Normand, Douglas J. Debski, James D. Simpson, and Dr. Samuel C. Hadaway. The Company’s initial filing sought Commission approval for an annual increase of $4,578,140 in distribution revenues, based upon a test year ending December 31, 2012; an overall weighted average rate of return on rate base of 8.54%; and certain known and measurable adjustments to test year revenues, expenses, and rate base. The Company requested that the new rates become effective on January 1, 2014, consistent with the Stipulation previously approved by the Commission in the Company’s prior base rate proceeding, Docket No. 2011-0092.

In addition, the Company requested approval to implement a multi-year alternative rate plan (“Rate Plan”) that would allow for future changes in the Company’s distribution rates, without the need to file a general rate case, for a defined period of time. The Company structured the Rate Plan around a proposal to implement an annual capital cost recovery mechanism to recover the costs of targeted improvements and upgrades to the Company’s distribution system and other safety related improvements, which mechanism known as the Targeted Infrastructure Recovery


STIPULATION

Docket No. 2013-00133

Adjustment (“TIRA”). These system upgrade programs include a) the Cast Iron Replacement Program (“CIRP”) approved by the Commission in Docket No. 2008-151; b) the replacement of bare steel and non-cathodically protected (unprotected) coated steel mains and services; and (c) replacement of farm tap regulators (together, “Eligible Facilities”). The Company proposed the first annual TIRA adjustment for May 1, 2014, to recover the Company’s 2013 investment costs of these programs and improvements.

The Company also submitted an Accounting Cost of Service Study and a Marginal Cost of Service Study and proposed changes in rate design to reallocate recovery among classes in order to better reflect costs of service by class and to increase the fixed monthly customer charge, while decreasing volumetric usage changes.

By Notice of Proceeding issued on April 5, 2013, the Hearing Examiner opened this proceeding, established the deadline for Petitions to Intervene as April 29, 2013, and scheduled the Initial Case Conference for May 8, 2013. The Company mailed the Notice of Proceeding to its customers on April 11, 2014. At the Initial Case Conference, the Hearing Examiner granted the OPA’s Petition to Intervene.1 The Parties also discussed the remaining schedule for the case, which was confirmed in the Hearing Examiner’s Procedural Order dated June 24, 2013.

 

1  No other petitions to intervene were filed. Two individuals have filed public comments in this docket.

During May and June 2013, the Maine Public Utilities Staff (“the Staff”) and OPA issued numerous written Data Requests regarding the Company’s initial filing, to which the Company responded. During the course of the case, the Staff, OPA and the Company have issued more than 250 written and oral Data Requests. Many of these Data Requests had multiple subparts.

The Commission held a Technical Conference on May 31, 2013 on the Company’s Direct Testimony, during which both the OPA and the Staff asked questions of Company witnesses and made additional oral Data Requests of the Company. On June 18, 2013, the Commission held an additional Technical Conference to consider the CIRP, and to review the Company’s 2012 CIRP performance report and its CIRP plans for 2013. At this Technical Conference, the Hearing Examiner requested that the Company submit to the Commission previous responses of Fitchburg Gas and Electric Light Company to the Massachusetts Attorney General’s oversight questions (issued on April 11, 2013), regarding lost and accounted for gas and gas leaks. The Company complied with this request on June 24, 2013.

On July 9, the OPA filed the Direct Testimony, Exhibits, and work papers of three witnesses: Thomas S. Catlin, Jerome D. Mierzwa, and Johnny R. Brown. Mr. Catlin concluded that the Company had a revenue deficiency of $1,518,801, based on various adjustments to the Company’s proposed revenue requirements recommended by Mr. Mierzwa, Mr. Brown and Mr. Caitlin. On July 17, 2013, the Company submitted Data Requests to the OPA witnesses, to which the OPA responded.

On July 30, 2013, the Commission held a Technical Conference to allow questions on the OPA’s Direct Testimony, during which the Company and the Staff asked questions and made further, oral Data Requests of OPA’s witnesses.

The Hearing Examiner issued a Procedural Order on August 27, 2013, setting revised dates for the filing of the Bench Analysis, related discovery and responses, and the Technical Conference on the Bench Analysis.

The Staff issued its corrected Bench Analysis on September 12, 2013. The Company filed Data Requests on the Bench Analysis, to which the Staff responded. A Technical Conference on the Bench Analysis occurred on September 26, 2013, where the Company and OPA asked questions of Staff regarding the Bench Analysis. During the Technical Conference, the Company made further, oral Data Requests of Staff.

On October 8, 2013, the Company filed the Rebuttal Testimony of Mark H. Collin, Thomas P. Meissner, David L. Chong, Cindy L. Carroll, James D. Simpson, and Dr. Samuel C. Hadaway. The Company’s Rebuttal Testimony included an amended revenue requirement, reflecting a distribution revenue increase of $4,850,687, described the changes made to

the Company’s revenue requirement calculations, and proposed certain changes to its Rate Plan and TIRA. The Company filed the Appendix to the Rebuttal Testimony of Mr. Collin on October 9, 2013. On October 11, 2013, both the OPA and Staff issued Data Requests regarding the Company’s Rebuttal Testimony, to which the Company responded.

On October 18, 2013, the Parties, including Staff, engaged in settlement negotiations in person that resulted in the Parties reaching agreement on this Stipulation. These negotiations were preceded by phone calls and email exchanges between the Parties and Staff with respect to the terms of a negotiated settlement.

III. RECOMMENDED APPROVALS AND FINDINGS

Based on the record in this case, the Parties to this Stipulation agree and recommend that the Commission issue an Order that approves, accepts, and adopts this Stipulation, as just and reasonable and in the public interest, including the following provisions:

A. DISTRIBUTION RATE CHANGES

The Parties agree to an increase in the Company’s distribution revenues of $3,801,564 which consists of an increase in delivery revenues of $3,444,259 and an increase in production revenues of $357,304.2 Rates derived to recover the delivery revenue requirement increase to take effect on January 1, 2014 are attached to this Stipulation as Exhibit 1.

 

2 

With this increase, total production revenues of $1,138,171 will be included and collected within the Cost of Gas Factor Clause (CGFC) effective January 1, 2014. Per Second Revised Page 41 of Northern’s tariff, within the CGFC, Local Production Capacity and Storage Costs include the costs of providing storage supply service from the Company’s on-system supplemental gas facilities as well as any miscellaneous Administration and General costs associated with providing gas supply service, as determined in the Company’s most recent rate case proceeding or rate design proceeding.


STIPULATION

Docket No. 2013-00133

Page 7 of 16

 

Rate Base: The Company’s revenue requirement is calculated based on a rate base of $111,760,626.

Cost of Capital: The Company’s revenue requirement is calculated on the basis of a weighted average cost of capital of 8.40% and a pretax weighted cost of capital of 11.75%. The cost of capital is applied to the rate base of $111,760,626.

B. RATE DESIGN

Class Allocation: The Company’s revenue requirement associated with the base rate increase described in Section III. A, above, shall be allocated to customer classes to generate the distribution charges for effect on January 1, 2014 indicated in Exhibit 1, attached to this Stipulation. This rate design allocates a higher percentage of revenue requirements to fixed monthly customer distribution charges and a lower percentage of revenue requirements to seasonal volumetric distribution charges and rate blocks than does the current rate design.


STIPULATION

Docket No. 2013-00133

Page 8 of 16

 

In addition, rate design changes to the customer and volumetric charges for the Residential Non-Heating Class (R-1) will be phased in as described herein such that at the end of the R-1 phase-in the customer charges for R-1 and the Residential Heating Class (R-2) will be equal and the first block volumetric charges for R-1 will be 81.65% of the R-2 first block volumetric charges and the second block volumetric charges for R-1 will be 81.09% of the R-2 second block volumetric charges. The phase-in methodology is described in the paragraph below.

Three R-1 phase-in steps, each implementing approximately one-third of the changes to Residential Non-Heating Class volumetric and monthly customer charges, will take effect on January 1, 2014; May 1, 2015; and May 1, 2016. The first phase-in adjustment will be on January 1, 2014 with the distribution base rates for all classes as shown in Exhibit 1. The second phase-in adjustment for R-1, which will occur on May 1, 2015, will be calculated as approximately half of the amount needed to reach the target levels described above. The calculation will take place following the application of the TIRA adjustment to rates. After the third and final phase-in adjustment on May 1, 2016, the R-1 and R-2 customer charges will be equal and the R-1 and R-2 volumetric distribution charges will be in the same proportion as described above. This calculation will take place following the application of the annual TIRA adjustment to rates.


STIPULATION

Docket No. 2013-00133

Page 9 of 16

 

With the first phase-in implemented on January 1, 2014, the resulting $338,725 revenue shortfall will be collected from all customer classes via an increase in customer and volumetric charges on a pro-rata basis. When the second and final R-1 phase-in adjustments are made, the customer and volumetric charges for all customer classes will be reduced on a pro-rata basis by the amount of incremental revenue that will result from the R-1 phase-in such that the Company’s total distribution revenue will be neutral when calculated based on weather normalized billing units from the immediately prior calendar year.

C. TIRA (TARGETED INFRASTRUCTURE REPLACEMENT ADJUSTMENT)

The Parties agree that the Company shall be allowed to implement, pursuant to the tariff attached to this Stipulation as Exhibit 2, a Targeted Infrastructure Replacement Adjustment (“TIRA”) which will provide for annual adjustments to distribution base rates to recover costs associated with the Company’s investments in targeted operational and safety-related infrastructure replacement and upgrade projects as described in Exhibit 2.

1. Eligible Facilities

The TIRA will allow for the recovery by the Company of prudently-incurred investments in the Eligible Facilities, which include facilities defined in the scope of work for (1) the Cast Iron Replacement Program (“CIRP”), approved by the Commission in Docket No. 2008-151, (2) the replacement of bare steel and non-cathodically protected (“unprotected”) coated steel mains and services, and (3) the replacement of farm tap regulators, all as described more fully in Section 4.03 of Exhibit 2. The scopes of work and schedules for the programs identified in (2) and (3) shall be specified in a Commission Order following the compliance filing in this proceeding described in Paragraph III. C. 5, below.


STIPULATION

Docket No. 2013-00133

Page 10 of 16

 

2. Term and Effective Dates

The TIRA will have an initial term of four (4) years, and applies to investments made in Eligible Facilities in each of the Calendar Years 2013, 2014, 2015, and 2016. The Company’s TIRA filing is due by February 28 of each year. Subject to review and approval by the Commission, the TIRA-adjusted distribution base rates shall become effective for service rendered on and after May 1 of 2014, 2015, 2016, and 2017. In the event the Company files a base rate case prior to the end of the initial term, the resulting revenue requirement shall be pro formed to reflect annualization of any TIRA rate adjustment not fully reflected in the test year. Any request to renew or extend the TIRA beyond its initial term shall be subject to Commission review and approval.

3. Calculation

The annual TIRA adjustment will be calculated using the most recently completed Calendar Year weather-normalized firm sales and delivery service revenue, will include indirect overheads, use a pretax weighted average cost of capital of 11.00%, and include an operations and maintenance (“O&M”) offset of $5,544 per mile of cast iron, bare steel and non-cathodically protected (unprotected) coated steel mains taken out of service. An example illustrating this calculation, including annual depreciation rates, is set forth in Exhibit 3.


STIPULATION

Docket No. 2013-00133

Page 11 of 16

 

4. TIRA Rate Impact Cap

The TIRA Rate Impact Cap shall be set at 4% of the Company’s distribution revenues. Amounts in excess of the TIRA rate impact cap shall be deferred and shall accrue carrying costs at the prime rate. The prime rate shall be fixed on a quarterly basis and established as reported in the Wall Street Journal on the first business day of the month preceding the calendar quarter. If more than one prime rate is reported, the average of the reported prime rates shall be utilized.

5. Compliance Filing; Performance Standard

The Company agrees to submit a filing by December 31, 2013 detailing the scopes and schedules for the unprotected steel and farm tap regulator programs. The filing will provide project cost estimates, the support for such estimates, project schedules, and revisions to the Earned Value Management (“EVM”) model that would permit tracking of cost and schedule performance metrics of the combined scope of work including the CIRP, unprotected steel and farm tap regulator replacement programs. The project scopes of the unprotected steel and farm tap regulator replacement programs, EVM revisions and performance metrics will be established by a Commission Order following this compliance filing.


STIPULATION

Docket No. 2013-00133

Page 12 of 16

 

If, in any year, one or more of the EVM performance indices (on a cumulative life-to-date basis) applicable to the Eligible Facilities falls below 100%, then the TIRA for that year will be suspended pending a review by the Commission of the reasonableness of the schedule and costs associated with the program.

D. EARNINGS SHARING

The Company will be allowed to retain all earnings up to a return on equity of 10%. Earnings in excess of 10% and up to an including 11% will be shared equally, 50/50, between ratepayers and the Company. Earnings in excess of 11% shall be returned to ratepayers. See the TIRA tariff, Exhibit 2.

The methodology for determining earnings and calculating potential earnings sharing is illustrated in Exhibit 4. As Exhibit 4 demonstrates, for purposes of calculating the earnings sharing, the Company’s earnings shall be calculated in accordance with the manner in which earnings are calculated in its Annual Report filed with the Commission but with revenues adjusted to reflect weather normalization and the removal of unbilled revenue.

E. REQUESTS FOR NEW CUSTOMER SERVICE AND SERVICE QUALITY BENCHMARKS

1. REQUESTS FOR NEW CUSTOMER SERVICE

The Company agrees to work with Staff and the OPA to study and develop a benchmark for tracking requests for new customer service and the Company’s responses to such requests. The intent of this study is to develop a service quality metric with respect to new service appointments that reflects the factors within the Company’s control in terms of handling requests for new service. The study will take place during 2014 and will be implemented, once agreed upon by Staff, OPA and the Company, and approved by the Commission, but not later than May 1, 2015.

2. SERVICE QUALITY BENCHMARKS

Certain of the Company’s current service quality benchmarks and their respective weights shall be amended and replaced in accordance with Exhibit 5. In addition, the maximum penalty amount for which the Company is responsible during any calendar year shall be $500,000. These amended service quality benchmarks shall be applicable to service provided beginning January 1, 2014.

F. Other Tariff Issues

Exhibit 6 includes individual tariff pages reflecting this settlement. Also, Exhibit 6 includes revised tariff pages filed by the Company in this proceeding and in compliance with Section 5.C.2 of Chapter 120 and not revised by this Stipulation because they reflect housekeeping issues only. These tariff pages shall become effective January 1, 2014.

  4.05 Limitation on Recovery

The TIRA Revenue Requirements allowable for recovery in the current Calendar Year shall not exceed four percent (4.0%) of total weather-normalized Distribution Revenues for total sales in the above Rate Classes. Total weather-normalized Distribution Revenues will be calculated using then-current distribution base rates and weather-normalized sales levels for the immediately preceding Calendar Year. Any TIRA Revenue Requirements over this 4% limit will be deferred with interest at the prime rate and added to the TIRA Revenue Requirements for recovery in subsequent year(s), subject to this same 4% limitation.

 

  4.06 Performance Standard

If, in any year, the TIRA Performance Indices (on a cumulative life-to-date basis) applicable to the Eligible Facilities, as approved by the MPUC, falls below 100%, then the TIRA for that year will be suspended pending a more comprehensive review by the MPUC of the reasonableness of the schedule and costs associated with the program.

 

  4.07 Calculation of TIRA Revenue Requirement

The annual TIRA, not to exceed the cap pursuant to §4.05, will be calculated as a percentage change to current base rates and will be based upon the TIRA Revenue Requirement as a percentage of the previous year’s weather-normalized Distribution Revenue. The TIRA Revenue Requirement will be the sum of the annual Depreciation Expense, estimated property tax expense based on the Property Tax Rate, Operation and Maintenance Expense Offset and allowed return for the Eligible Facilities. The allowed return shall be calculated by multiplying the sum of the properly capitalizable costs less the related Accumulated Reserve for Depreciation and Accumulated Deferred Income Taxes by a pre-tax rate of return of 11.00%. The TIRA calculations shall use the methodology illustrated in the Stipulation approved by the MPUC in Docket No. 2013-00133.

 

  4.08 Adjustment to Distribution Base Rates

Effective each May 1 for the years 2014, 2015, 2016, and 2017, the Company’s distribution base rate customer and usage charges for each Rate Class shall be adjusted. To determine the Company’s base distribution peak and off peak customer and volumetric rates to be effective May 1 of each current Calendar Year, the base distribution peak and off peak rates that are in effect just prior to May 1 of that Calendar Year will be multiplied by the TIRA Adjustment Multiplier. The TIRA Adjustment Multiplier will be calculated by dividing (1) the sum of the prior Calendar Year’s weather-normalized Distribution Revenues plus the current Calendar Year annual TIRA Revenue Requirement by (2) the prior Calendar Year weather-normalized Distribution Revenues. Weather-normalized Distribution Revenues will be calculated by multiplying the distribution peak and off peak base rates that are in effect just prior to May 1 of the current Calendar Year by the weather-normalized sales for the immediately preceding Calendar Year, plus actual booked customer charges.

5.0 Earnings Sharing Mechanism (“ESM”)

 

  5.01 Purpose

The purpose of the ESM is to allow for the sharing with customers of any Company excess earnings, as defined below, which occur in Calendar Years 2013, 2014, 2015 and 2016. The Company shall be allowed to retain all earnings that result in a return on equity (“ROE”) of up to and including 10%. Any earnings that result in a ROE in excess of 10% and up to and including 11% shall be shared equally (50/50) between the Company and customers. Any earnings that result in a ROE in excess of 11% shall be returned to customers in accordance with the procedures described below.

 

  5.02 Effective Date

The ESM adjustment rate shall be determined annually by the Company during the term of the TIRA and subject to review and approval by the MPUC. The ESM filing shall be made by February 28 of each year and shall be based on earnings and sales for the most recent completed Calendar Year. The ESM adjustment rate (if applicable) shall become effective for service rendered on and after May 1 of 2014, 2015, 2016 and 2017.

 

  5.03 ESM Calculation

The ESM calculation shall be made in accordance with the methodology illustrated in the Stipulation approved by the MPUC in Docket No. 2013-00133. For purposes of the ESM, the calculation of the ROE shall be based on the calculation of the Return on Common Equity Subject to MPUC Jurisdiction (Page 16-A, Line 24) as submitted in the Company’s Annual Report to the MPUC, with modification to include a weather normalization and unbilled revenue adjustments.

The Customer ESM Share shall be a percentage of the ESM Amount as provided below:

 

  1) For any year in which the Company’s ROE is less than or equal to 10%, the Customer ESM Share shall be 0%.

 

  2) For any year in which the Company’s ROE is greater than 10% but less than or equal to 11%, the Customer ESM Share shall be 50% of all amounts above a 10% ROE.

 

  3) For any year in which the Company’s ROE is greater than 11%, the Customer ESM Share shall be 50% of all amounts from 10% up to and including 11%, and 100% of all amounts above 11%.

Northern Utilities, Inc.    Superseding Second Revised Page 30.6
TARGETED INFRASTRUCTURE REPLACEMENT ADJUSTMENT

 

For any recently completed Calendar Year subject to this ESM in which the Company’s earnings result in a ROE that exceeds 10%, the volumetric (per ccf) base rates charged to sales and delivery service customers shall be adjusted by a uniform volumetric ESM adjustment rate effective for a 12-month period that begins each May 1. The ESM adjustment rate shall be calculated by dividing the Customer ESM Share by the total weather normalized customer volumes during the most recently completed Calendar Year in which the excess earnings occurred. For purposes of clarity, for each recently completed Calendar Year subject to this ESM, the ESM adjustment rate shall be effective for a 12-month period the begins each May 1 and ends on April 30 of the succeeding year.
