CASE NO. INT.G.17.O3
COMMENTS OF THE
COMMISSION STAFF
COMES NOW the Staff of the Idaho Public Utilities Commission, by and through its
Attorney of record, Daphne Huang, Deputy Attorney General, submits the following comments.
BACKGROUND
On July 27,2017,Intermountain Gas Company asked the Commission for authority to
implement a Demand Side Management (DSM) Program Funding Mechanism and DSM Charge.
Although the Commission has yet to formally accept a tariff filing from the Company, adraft
tariff was submitted as an exhibit during the Company's recent rate case, in which the
Commission authorized the Company to implement a residential DSM program. Order No.
33757 at37-38. Intermountain asks that its Application be processed by Modif,red Procedure,
and requests an effective date of October 7,2017 , to coincide with the requested effective date
for its annual Purchased Gas Cost Adjustment filing.

STAFF COMMENTS SEPTEMBER 15,2017
"DSM" generally refers to utility activities and programs that encourage customers to use
less overall energy, either through efficiency programs or peak load control measures. The
Commission authorized the Company to implement a DSM program, finding that "DSM, as both
a least-cost resource and an important element of promoting energy efficiency, is an important
part of any utility's provision of service." OrderNo. 33757 at37; see Applicationat2.
The Company seeks "to define and formalize amechanism whereby the Company can
recover costs incurred in the administration and delivery of its Rate Schedule DSM Energy
Efficiency" and submits a proposed budget for recovery. Application at 3. The Company states
that its costs for administering its DSM program may include energy efficiency program rebates;
administration ramp-up expenses and incremental staffing; DSM outreach; local support for
promotion of tariff-approved DSM measures; and encouraging market transformation through
adaptation of energy efficiency technologies. /d The Company reports that all DSM activities
are designed for its residential customers. .Id
The Company proposes a recovery mechanism in which it submits its "annual budget
of anticipated administrative and program costs related to the Company's DSM program." Id.
In its annual filing, the Company will request the Commission's ruling that its "expenses are
both reasonable and prudent." 1d Also, the Company's budget will include "any surplus or
deficit associated with the collection of DSM funds and the incurrence of DSM-related
expenses." 1d.
Program Budget
The Company's proposed2}lT-2Ol8 DSM budget totals $777,000 which includes
$600,000 in rebate expenses, $147,000 in personnel expenses, and $30,000 in program delivery
and ramp-up expenses. Staff finds the proposed budget to be reasonable for the expenses
associated with a new program limited to residential customers.
2STAFF COMMENTS SEPTEMBER 15,2017
STAFF ANALYSIS
Staff has reviewed the Company's Application and accompanying exhibits. Based on its
review, Staff supports the Company's DSM funding requirements and proposed tariff rider
charge. In the comments below, Staff addresses the Company's DSM funding, program
structure, accounting methods, reporting requirements, and customer considerations.
The Company's proposed DSM tariff rider amount is calculated by dividing the $777,000
budget by Rate Schedule RS 21 1,957,936 normalized 2016 therm sales to arrive at a surcharge of
$0.00367 per therm. This is approximately $0.22 per bill for an average customer using
approximately 61 therms per month. Staff notes that because the tariff rider rate is calculated
based on 20 I 6 normalized therm sales, customer growth that occurr ed in 2017 will likely provide
additional revenue over what the Company has forecasted. All DSM funds collected will be
allocated to costs incurred in the administration and delivery of its proposed DSM program, and
accounting records will be maintained to track actual expenses versus the DSM tariff rider
amount collected from residential customers. Any over-collection of DSM funds will be used to
offset future expenses or returned to customers.
The Company proposes a recovery mechanism in which it submits an annual budget
of anticipated administrative and program costs. As part of that filing, the Company will request
the Commission's ruling that its expenses are both reasonable and prudent. Also, the Company's
budget will include any surplus or deficit associated with the collection of DSM funds and the
incurrence of DSM-related expenses. While Staff recognizes the need for periodic filings to
review the Company's programs and determine the prudency of program expenses, Staff does
not believe that review constitutes advance prudency or expense approval. Staff also does not
believe that annual filings are necessary for adjusting the DSM tariff rider rate. Instead of
mandated, automatic reviews each year, Staff believes it is reasonable for the Commission to
allow the Company to file revisions to its tariff rider at any time deemed necessary and
appropriate. Staff recognizes that in its ramp up stages, the tariff rider rate may need to be
adjusted more frequently as the Company's programs expand to include additional residential
measures, as well as measures for general service and large volume customer classes.
Program Structure
The Company's supplemental filing in this case included its tariffs which defined the
proposed measures and rebate amounts. As shown in Table 1 below, these are the same
measures and rebate amounts the Company proposed in its recent rate case, INT-G-16-02. The
Company proposes two tiers; Tier One incentives apply when customers install high-efficiency
natural gas equipment and Tier Two incentives apply when customers install high-efficiency
equipment when they convert to natural gas for water or space heat. The measures in both tiers
are identical, but Tier Two incentives are higher than Tier One incentives. Additionally, Tier
JSTAFF COMMENTS SEPTEMBER I5,20I7
Two includes an incentive for new-construction Energy Star Homes with natural gas water and
space heating.
Table 1: Company Proposed Measures/Incentives
Staff witness Donohue expressed concern about Tier Two incentives on pages 9 - 12 of
her direct testimony in Case No. INT-G-16-02. To summarize,the Company's cost-
effectiveness calculations show that except for the higher incentive cost, Tier Two measures
have the same measure costs and energy savings as Tier One measures. The Company claims
that the higher incentive amount for Tier Two is intended to address the additional cost of fuel
conversions, but the cost ofthe fuel conversion is not included in the cost-effectiveness
calculations. Staff believes that if the measure costs and energy savings are the same, then the

STAFF COMMENTS SEPTEMBER 15,2017
incentive amounts should also align. Staff also points out that three of the seven proposed Tier
Two measures are not cost-effective due to the higher incentive amount.l
Staff acknowledges that Order No. 33757 reads, "Accordingly, we find it reasonable to
authorize the Company to implement its proposed DSM program, recognizing that the Company
represents that this program will be used as a starting point from which to develop more robust
DSM offerings. We look forward to seeing the program develop." Order at37. However, Staff
notes that the Commission Order did not discuss or specifically support either the Company or
Staff s position on Tier Two incentives. Therefore, Staff respectfully requests that the
Commission clarify its direction on Tier Two incentives.
As part of its clarification, Staff recommends that the Commission direct the Company to
consolidate its incentives into a single tier at the Tier One incentive level and retain the proposed
incentive amount for the Energy Star Homes measure. Staff points out that under this proposal,
customers who convert to natural gas space or water heat will still be eligible for incentives when
they install high-efficiency equipment. Since all of the same customers will still be eligible for
incentives, Staff does not believe that consolidating the tiers will have a detrimental impact on
the cost, participation, or cost-effectiveness of the DSM program. In addition, Staff is willing to
work with the Company to improve its cost-effectiveness calculations so that Staff could
potentially support a proposal for Tier Two incentives in the future.
Accounting Treatment
Staff met with the Company and discussed the accounting treatment used to establish a
balancing account for the energy efficiency program expenses and tariffrider revenues. Staff
believes that tariff rider revenues should be calculated and booked independently from the
Company's normal sales revenue, expenses should be tracked separately from the Company's
Operations and Maintenance (O&M) expenses, and a mechanism should exist to separate labor
related expenses, promotional expenses, rebates, and other energy efficiency program related
expenses.
Through discussions, the Company proposes to record all costs to a Business Unit which
will be incorporated into Intermountain's Regulatory Department. Detailed cost segregation will
I See INT-G-16-02, Spector Exhibit 26. On the table titled "Direct Use Rebate Under Utility Cost Test," the "UCT
with Program Admin Costs" column shows that three of the seven proposed measures exceed the cost-effectiveness
threshold of $0.53 I 82.

be facilitated by charging all program expenses to a sub-account of FERC account 908 -
Customer Assistance Expense. To facilitate non-labor expense reporting, unique work orders
will be used to track rebates, promotional expenses, and other program expenses. Revenues
generated from the Energy Efficiency Charge will be deferred to a Regulatory Liability account
(FERC 254). Deferred revenue will be reclassified monthly to Retail Revenue and then used to
offset the expenses as they are incurred. Staff believes the proposed accounting treatment will
accommodate the requirements for maintaining a balancing account for the energy efficiency
programs' revenues and expenses.
Reporting Requirements and Prudency Determinations
Staff discussed reporting with the Company and recommends that the Company provide a
quarterly update on the year-to-date status of the balancing account which would include
monthly revenues, monthly expenditures, and number of rebates issued by measure. Staff
anticipates that this brief update will be emailed to interested stakeholders and would help inform
decisions about the need to adjust the tariff rider amount. In addition, Staff recommends that the
Company convene interested stakeholders in person twice ayear to provide an opportunity for
the Company to answer questions and to solicit feedback.
Staff supports the Company's commitment to file an annual DSM report to document
program performance. This report should include a summary of cost-effectiveness, expenditures,
participation (number of rebates issued), and program implementation methods for each of the
incented measures. These annual reports will be used to determine the reasonableness of the
Company's expenditures when the Company files for prudency, which Staff anticipates will
happen at least every two years.
These recommendations are consistent with reporting standards in place for other
utilities. However, Staff has deliberately streamlined the reporting requirements so that it does
not unduly interfere with the program's start-up phase.
Tariff Revisions
Staff has worked with the Company to revise the proposed Rate Schedules DSM and
DSM Charge submitted as part of the Company's Application. Revisions were made primarily
to clarify and simplify these Schedules as shown in Attachment 1. With the exception of Tier
Two incentives, it is Staffls understanding that the Company agrees with the proposed changes.
6STAFF COMMENTS SEPTEMBER 15,2017
The first change is to rename the schedules. Staff recommends changing the Company's
proposed "Rate Schedule DSM" to "Rate Schedule EE" and the proposed "Rate Schedule DSM
Charge" to "Rate Schedule EEC." These changes were made to more clearly reflect the
program's focus on energy efficiency.
Another change was made to remove the term "standard efficiency" in the program
description of the proposed Rate Schedule DSM. The Company's proposed Schedule does not
define the term and Staff notes that what is considered "standard efficiency" may change over
time. Removing the term "standard efficiency" makes it easier for customers to understand who
qualifies for the equipment incentives specified in the Schedule. Staff does not anticipate that
this change will impact program savings. Staff recommends the Company maintain detailed
records regarding replaced equipment in order to monitor and address any issues that might
si gnifi cantly affect pro gram co st- effectivene s s.
In addition to revising the two proposed rates schedules submitted as part of the
Company's Application, Staff worked with the Company to revise language in its existing Rate
Schedule RS to reflect the Company's proposed Rate Schedule DSM Charge. Staff worked with
the Company to clarify the existing tariff as well as include language pertaining to the proposed
energy efficiency charge. Both Staff and the Company agree that the proposed charge should be
included as a line item on customers' bills, which is reflected in Staff s proposed Rate Schedule
RS as shown in Attachment2.
Attachment Nos. 1 and2 reflect changes to the proposed tariffs filed by the Company in
this case. With the exception of Staff s recommended changes to Tier Two incentives, both the
Company and Staff have agreed to the revised tariff language shown in the attachments. If the
Commission directs the Company to modify its proposed energy efficiency program, Staff
recommends the Commission direct the Company to work with Staff to modify the tariffs in
compliance with the Commission's order.
CUSTOMER NOTICE AND PRESS RELEASE
The Company's press release and customer notice were included with its Application.
Staff reviewed the documents and determined that they complied with Rule 125 of the
Commission's Rules of Procedure. IDAPA 31.01.01.125. The notice was included with bills
sent to customers beginning August 1,2017 and ending September 1,2017 . Customers have the
7STAFF COMMENTS SEPTEMBER I5,2017
opportunity to file comments on or before the Commission's comment deadline of September 15,
2017.
CUSTOMER COMMENTS
As of September 15,2017, the Commission has received five comments that are opposed
to the Company's proposed DSM program.
CONCLUSION AND RECOMMENDATIONS
Staff supports implementation of the Company's cost-effective natural gas DSM program
because it reduces resource costs for all customers. Staff recommends approval of the funding
amount, funding mechanism, and proposed accounting treatment. However, Staff s support does
not constitute an advance recommendation of prudency. Staff will carefully review program
expenses, implementation, and cost-effectiveness calculations when the Company files for
prudency of those expenses.
Specifically, Staff recommends that:
l. The Commission approve the Company's proposed charge of $0.00367 per therm for
Rate Schedule EEC.
2. The Commission direct the Company to consolidate its incentives into a single tier at
the Tier One level and retain the proposed incentive amount for the Energy Star
Homes measure.
3. The Commission approve the revised Rate Schedules EE, EEC, and RS and direct the
Company to work with Staff to make further revisions as necessary based on the
Commission's decision, and that the Company file conforming tariffs.
