CASE NO. PAC-E-22-15

APPLICATION

Rocky Mountain Power, a division of PacifiCorp (the “Company”), hereby petitions
the Idaho Public Utilities Commission (the “Commission”) for authority to modernize its
residential rates over a five-year transition period (“Residential Rate Modernization Plan”). In
support of this Application, Rocky Mountain Power states:
1. The Company is an Oregon corporation providing electric service to retail
customers as Rocky Mountain Power in the states of Idaho, Utah, and Wyoming, and as Pacific
Power in the states of California, Oregon, and Washington.
2. Rocky Mountain Power is authorized to do business in the state of Idaho as a
public utility providing retail electric service to approximately 86,500 customers. Rocky
Mountain Power is a public utility subject to the jurisdiction of the Commission pursuant to
Idaho Code § 61-129.
3. This Application is filed pursuant to Commission Procedural Rules 52 and 121
and Idaho Code §§ 61-301, 61-307, 61-622, and 61-623. Commission Procedural Rules 52 and
121 provide for an application to change rates. Idaho Code § 61-623 empowers the
Commission to determine the propriety of proposed rate schedules, §§ 61-307 and 61-622
APPLICATION OF Page 2 ROCKY MOUNTAIN POWER
require Commission approval prior to any change in rates, and § 61-301 requires Idaho retail
electric rates to be just and reasonable.
4. Communications regarding this Application should be addressed to:

5. This Application seeks Commission approval of the Residential Rate
Modernization Plan. The Residential Rate Modernization Plan proposes to modify residential
rates over a five-year transition period in the following ways:
a) Increase the Customer Service Charge for both Electric Service Schedule No. 1
– Residential Service (“Schedule 1”) and Electric Service Schedule No. 36 –
Optional Time of Day – Residential Service (“Schedule 36”) to $29.25 per
month and lower Energy Charges commensurately.
b) Eliminate inclining block tiered rates for Schedule 1, so that Energy Charges
are flat in each season.
APPLICATION OF Page 3 ROCKY MOUNTAIN POWER
c) Change the time of use periods in Schedule 36, so the definitions of on- and off-
peak periods match those listed on Electric Service Schedule No. 9 – General
Service – High Voltage (“Schedule 9”).
6. Rocky Mountain Power’s direct case consists of this Application and the
testimony and exhibits of Robert M. Meredith. Mr. Meredith’s testimony provides an overview
of the rationale of the Residential Rate Modernization Plan, discusses the calculations that
support the Company’s proposed multi-year prices, and describes the estimated customer
billing impact. Mr. Meredith’s testimony is supported by five exhibits. Below is a summary of
each exhibit:
a) Exhibit No. 1 contains a break-down of the cost-of-service by different
categories for the two residential classes expressed in dollars per kWh and
dollars per customer per month.
b) Exhibit No. 2 summarizes the proposed prices, billing determinants, and
anticipated revenue for the Residential Rate Modernization Plan.
c) Exhibit No. 3 has the billing comparisons and distribution of the bill impacts to
individual customers for the Residential Rate Modernization Plan.
d) Exhibit No. 4 is the Company’s proposed redlined revised tariff sheets.
e) Exhibit No. 5 is the Company’s proposed revised tariff sheets.
7. As illustrated in the testimony and exhibits of Mr. Meredith, as currently
designed, the Company’s residential rates do not align well with cost causation. The current
residential rate structure is comprised of the Customer Service Charge, which is a monthly
fixed charge, and Energy Charges, which are usage- based or volumetric charges. The
Customer Service Charge falls far short of covering the fixed costs that are incurred by
APPLICATION OF Page 4 ROCKY MOUNTAIN POWER
residential customers and those fixed costs are therefore recovered through the volumetric
Energy Charges. Accordingly, the Company proposes to increase the monthly Customer
Service Charge and commensurately lower the volumetric Energy Charge for Schedules 1 and
36 over a five-year transition period to better align residential rates with the cost causation.
Further, having the same Customer Service Charge for both Schedule 1 and Schedule 36 would
prevent customers from choosing one schedule over the other based upon the Customer Service
Charge.
8. As illustrated in the testimony and exhibits of Mr. Meredith, Schedule 1
customers are subject to seasonal inclining block tiered rates that are not economically justified
and unduly penalize certain customers. Eliminating tiered rates from Schedule 1 also makes
the comparison to Schedule 36, which does not have tiers, easier for customers to assess
regarding the potential benefits of time varying pricing. A customer’s decision to opt into the
voluntary Schedule 36 time of use program should be motivated by a desire to shift load to
lower cost times instead of taking advantage of the rate structure. Additionally, the current
time of use periods for Schedule 36 do not reflect the times when it is more costly for the
Company to serve. In the third year of the Residential Rate Modernization Plan, the time of
use definitions for Schedule 36 would be changed, so that the on-peak period aligns with what
is used for Schedule 9. These updated time of use periods would give customers a better price
signal to prioritize the more critical times when they should shift load.
9. As previously indicated, the Residential Rate Modernization Plan modifies
residential rates gradually over a five-year transition period to mitigate impacts on individual
customers. While some customer rates will decrease, others will see a slight increase that
results from these proposed changes. The Company’s customer impact analysis shows that, for
APPLICATION OF Page 5 ROCKY MOUNTAIN POWER
the majority of customers, any monthly impact from the proposed Residential Rate
Modernization Plan will be very modest.
10. The Residential Rate Modernization Plan is designed to be revenue neutral and
does not increase the overall revenue collected from customers.
11. In accordance with Commission Rule 121.01(g), Rocky Mountain Power's
system-wide costs were allocated1 to Idaho based on the approved 2020 PacifiCorp Inter-
Jurisdictional Allocation Protocol (“2020 Protocol”).2
12. As part of the Residential Rate Modification Plan, the Company plans to host
two customer outreach events. At these meetings, the Company will be available to take
feedback and answer questions about the plan. Dates and times for these customer outreach
events will be determined after a procedural schedule is established for this filing.
13. Rocky Mountain Power is notifying its customers of this Application by means
of a press release sent to local media organizations and bill inserts included in customer bills
over the course of the November billing cycle. A copy of the press release and bill insert is
provided as Attachment No. 1 to this Application. In addition, this Application will be made
available for review on the Company's website.
14. The Company believes that consideration of the proposals contained in this
Application do not require an evidentiary proceeding, and accordingly requests that this
Application be processed under modified procedure pursuant to Rules 201-204, which allows
for consideration of these issues by written submissions rather than by an evidentiary hearing.

Rocky Mountain Power respectfully requests that the Commission issue an Order authorizing
that this proceeding be processed under modified procedure.
15. The Company respectfully submits that the Commission's approval of Rocky
Mountain Power’s Application is in the public interest because it promotes residential rates
that align better with cost causation. In accordance with Commission Rule 121.01(d), Rocky
Mountain Power represents that it stands ready for immediate consideration of this
Application.
WHEREFORE, Rocky Mountain Power respectfully requests that the Commission
issue an Order: (1) authorizing that this proceeding be processed under modified procedure,
and (2) approving the implementation of the Residential Rate Modernization Plan effective
December 1, 2022.
DATED this 20th day of October 2022.

For release Oct. 20, 2022 FINAL DRAFT, rev. 10-20-22, 9 a.m. MDT

Changes proposed to modernize residential rates
New prices would better reflect costs and enhance fairness

BOISE — Rocky Mountain Power has proposed updated rates for residential customers to the Idaho
Public Utilities Commission for its review and approval. The changes are designed to balance the needs
of all customers while the utility continues building the secure energy grid of the future and implements
the transition to a net zero emissions future for electricity production.

Residential rates contain two components, a fixed monthly customer service charge and the energy rate,
or price per kilowatt-hour. The utility proposes a gradual transition over five years to increase the
customer service charge for the two main residential rate schedules, which will allow energy charges to
be reduced. The change is proposed for Electric Service Schedule No. 1 – Residential Service, and Electric
Service Schedule No. 36 – Optional Time-of-Day Residential Service.

Importantly, these updates to residential rates will not increase the amount of revenue for Rocky
Mountain Power. Rather, the change will ensure fairness for all residential customers, whether they are
large or small users of electricity. For most customers, the change to their monthly bill will be less than a
dollar in each of the annual price changes.

The variable cost of energy that customers use is a relatively small part of the cost of serving residential
customers, about 23 percent of the total. The remaining 77 percent of costs are fixed and are not driven
by energy consumption. Specifically, in its pricing proposal, the company is requesting to increase the
fixed customer service cost to better cover some of these costs which include the costs of installing and
maintaining neighborhood equipment, such as poles, wires, transformers and substations, together with
billing and other customer services. These costs of maintaining the distribution system and of providing
customer service don’t change with the volume of energy used.

By increasing the customer service charge to cover local neighborhood equipment and customer service,
and decreasing the per kilowatt-hour energy charge, residential customer rates will better cover the
actual costs of providing service, and ensure customers pay a fair price for the energy they use.

Rocky Mountain Power proposes to gradually increase the current $8 per month customer service
charge to $29.25 per month over five years. At the same time energy charges will be lowered
accordingly, keeping the overall revenue coming to the utility the same. The company proposes the first
change, from $8 to $12.25 for Schedule 1, with subsequent changes annually for the next four years.
These changes must be approved by the Idaho Public Utilities Commission.

The five-year transition to a more accurate customer service charge is in line with what other Idaho
electric utilities charge. A survey of fixed monthly charges for residential customers from 11 other
utilities shows that the average is about $23 per month, and ranges from $5 to $40.

In testimony filed to support the request, Rocky Mountain power outlined how the transition would
proceed, if approved. The table below shows how the customer service charge would increase over the
five-year transition for Residential Schedule 1 customers, and how energy charges would be reduced
accordingly.

For Schedule 36, Time-of-Use residential customers, the transition is detailed below:

For customers taking service on Time of Day Schedule 36 the rate modernization plan also includes
updates in the third year of the transition to shorten the on-peak period, better aligning the on-peak /
off-peak periods with today’s costs of providing energy.

For customers taking service on Standard Residential Schedule 1, tiered rates that penalize customers
with higher prices for monthly energy usage over 700 kilowatt-hours in the summer season and over
1,000 kilowatt-hours in the winter season, would be phased out over the transition period.

For some smaller energy users, they would pay a little more per month. The most a customer’s monthly
bill would increase would be about $4 in any of the annual price changes during the transition.
Generally, for customers who use more than average, their bills would decrease. For more details on
Rocky Mountain Power’s filing, visit https://www.rockymountainpower.net/about/rates-
regulation/idaho-regulatory-filings.html.

The Idaho commission will examine Rocky Mountain Power’s requests and will determine whether the
request should be accepted as filed, modified, or rejected. The public will have an opportunity to
comment on the proposal as the commission studies the company’s request. A copy of the company’s
application is available for public review on the commission’s website, www.puc.idaho.gov, under Case
No. PAC-E-22-15. Customers may also subscribe to the commission’s RSS feed to receive periodic
updates via email. The request is required to be available at the company’s offices in Rexburg, Preston,
Shelley and Montpelier, or on the company’s website above.

www.rockymountainpower.net.

On October 20, 2022, Rocky Mountain Power filed a request
with the Idaho Public Utilities Commission proposing to
modernize its prices for residential customers.
Residential rates contain two components, a fixed monthly
customer service charge and an energy rate or price per
kilowatt-hour. The utility proposes a gradual transition over
five years to increase the customer service charge for the two
residential rate schedules, which will allow energy charges to
be reduced. The change is proposed for Electric Service Schedule
No. 1 – Residential Service, and Electric Service Schedule
No. 36 – Optional Time-of-Day Residential Service.
For Schedule 1, Rocky Mountain Power proposes to gradually
increase the current $8 per month customer service charge
to $29.25 per month over five years. At the same time energy
charges will be lowered accordingly, keeping the overall revenue
coming to the utility the same. The company proposes the first
change, from $8 to $12.25 for Schedule 1, with subsequent
changes annually for the next four years. These changes must be
approved by the Idaho Public Utilities Commission.
If approved, the table below shows how the customer
service charge would increase over the five-year transition for
Residential Schedule 1 customers, and how energy charges
would be reduced accordingly.
For Schedule 36, Time-of-Use residential customers, the
transition is detailed below:
For customers taking service on Standard Residential Schedule
1, tiered rates that penalize customers with higher prices for
monthly energy usage over 700 kWh in the summer season and
over 1,000 kWh in the winter season would be phased out over
the transition period.
For customers taking service on Time of Day Schedule 36, the
request also includes updates in the third year of the transition
to shorten the on-peak period, better aligning the on-peak and
off-peak periods with today’s costs of providing energy.
For most customers, the change to their monthly bill will be
less than a dollar in each of the annual price changes. The most
a customer’s monthly bill would increase would be about $4 in
any of the annual price changes during the transition. Generally
for customers who use more energy than average, their bills
would decrease.
The Idaho commission will examine Rocky Mountain Power’s
request and will determine whether the request should be
accepted as filed, modified, or rejected.
The public may comment on the proposal as the commission
studies the company’s request. A copy of the company’s
application is available for public review on the commission’s
website, www.puc.idaho.gov, under Case No. PAC-E-22-15.
Customers may also subscribe to the commission’s RSS feed to

Q. What is the Company’s Residential Rate Modernization Plan? 22
A. The Company proposes a five-year transition period to modify the structure of its 23

Meredith, Di-3
Rocky Mountain Power
residential rates in the following ways: 1
1. Increase the Customer Service Charge for both Electric Service Schedule No. 1 – 2
Residential Service (“Schedule 1”) and Electric Service Schedule No. 36 – Optional 3
Time of Day – Residential Service (“Schedule 36”) to $29.25 per month and lower 4
Energy Charges commensurately. If the Company files a general rates case during 5
the Residential Rate Modernization Plan the rates in this application would be 6
updated to reflect any Commission approved rate changes. 7
2. Eliminate inclining block tiered rates for Schedule 1, so that Energy Charges are 8
flat in each season. 9
3. Change the time of use periods in Schedule 36, so that the definitions of on- and 10
off-peak periods match those listed on Electric Service Schedule No. 9 – General 11
Service – High Voltage (“Schedule 9”). 12
Q. When does the Company propose these changes occur? 13
A. The Company proposes that the first price change occur on December 1, 2022. 14
Subsequent price changes would take effect on December 1 with the final change of 15
the transition occurring on December 1, 2026. 16
Q. Has the Company provided proposed revised tariffs for these changes? 17
A. Yes. Exhibit No. 5 contains proposed tariff revisions to Schedules 1 and 36. 18
Q. Are the proposed tariff revisions to Schedules 1 and 36 revenue neutral for the 19
Company? 20
A. Yes. The Residential Rate Modernization Plan is revenue neutral and does not modify 21
the Company’s revenue requirement. 22

Meredith, Di-4
Rocky Mountain Power
Q. How does the Company propose the Residential Rate Modernization Plan would 1
operate if the Company had a general rate case in the intervening years of the 2
transition period? 3
A. If there is a base rate change for residential customers as the result of a general rate 4
case, the Company proposes that the current residential prices at that time as well as 5
the prices laid out for subsequent transition periods would all change by an equal 6
percentage, so that the transition can proceed in an orderly manner. 7
Residential Rate Modernization Plan Rationale 8
Q. Why is the Company making this proposal? 9
A. The Company’s current residential rate structure does not adequately reflect cost 10
causation. The electric utility industry requires a significant amount of capital 11
infrastructure, which is largely a fixed cost once infrastructure goes into service. The 12
current residential rate structure is comprised of the Customer Service Charge, which 13
is a monthly fixed charge, and energy charges, which are usage- based or volumetric 14
charges. The Customer Service Charge falls far short of covering the fixed costs that 15
are incurred by residential customers and those fixed costs are therefore recovered 16
through volumetric energy charges. Energy Charges in Schedule 1 are also tiered, so 17
that usage over a specific threshold in a monthly billing period gets priced at a higher 18
rate. The effect of a low Customer Service Charge and tiered energy charges is that 19
customers with low monthly usage are subsidized by customers with higher monthly 20
usage. For Schedule 36, which is an optional time of use rate schedule, the time of use 21
period definitions have been the same for several decades, since the schedule’s 22
inception in the early 1980’s. The Company proposes modifying those definitions to 23

Meredith, Di-5
Rocky Mountain Power
better reflect the hourly differences in the Company’s cost of providing energy. 1
Q. Why isn’t the Company proposing to make these changes in general rate cases? 2
A. The Residential Rate Modernization Plan includes a five-year transition to gradually 3
update rate design. Progress was made in the Company’s most recent general rate case, 4
Case No. PAC-E-21-07 (“2021 Rate Case”), where the Company proposed and the 5
Commission approved an increase to the residential Customer Service Charge from $5 6
per month to $8 per month and a partial flattening of tiered Energy Charges. However, 7
rate cases historically have not been filed very often and prior to the 2021 Rate Case, 8
it had been about ten years since the Company’s last case in 2011, Case No. PAC-E-9
11-12. Further, a host of different issues are raised in general rate cases which can make 10
it challenging to make significant progress on rate design. In order to facilitate a 11
transition, the Company is requesting these changes to residential rates now so that the 12
intraclass subsidies between large and small users can be resolved sooner in this 13
proceeding, rather than in a future general rate case, and so that the other issues that 14
arise in a general rate case will not distract from progress on this important topic. 15
Q. Why is the Company proposing that these changes occur over a five-year 16
transition? 17
A. The Company is proposing that residential rates be modified gradually over this 18
timeframe to moderate bill impacts on individual customers. While it is important to 19
make these changes to better align rates with the cost of service, this must be balanced 20
with how these changes affect some customers. I will describe later in my testimony 21
the billing impact distribution of the price changes and why the Company’s proposal 22
achieves this balance. 23

Customer Service Charge 1
Q. What is the Customer Service Charge? 2
A. The Customer Service Charge is a flat fixed amount that a customer pays every month 3
regardless of usage. 4
Q. How much is the Customer Service Charge? 5
A. For Schedule 1, the Customer Service Charge is presently $8 per month.1 For Schedule 6
36, it is $15 per month. 7
Q. What proportion of a residential customer’s cost of service is related to fixed 8
costs? 9
A. On average, the cost of service for a residential customer is $97.32 per month. $22.84 10
or about 23 percent of this value is energy related. The remaining $74.48 or about 77 11
percent is fixed and not energy related. Exhibit No. 1 shows in greater detail how cost 12
of service breaks down by category for Schedule 1, Schedule 36, and for all residential 13
customers in total. To develop this exhibit and subsequent exhibits and pricing analysis 14
that I describe in this testimony, the cost-of-service study that the Company filed in the 15
2021 Rate Case was used, but with the final settled revenue requirement increase of 16
$8.0 million input into the model. 17
Q. What proportion of revenues from residential customers is recovered through the 18
fixed Customer Service Charge? 19
A. For Schedule 1, only about nine percent of revenue is recovered through the Customer 20

1 The Company recently filed a general rate case with the Commission to better align the revenues collected
with the cost of providing electric service to customers. In that case, the Company took the first step in over ten
years to increase the Customer Service Charge from $5 to $8 per month. In the Matter of the Application of
Rocky Mountain Power for Authority to increase Its Rates and Charges in Idaho and Approval of Proposed
Electric Service Schedules and Regulations, Case No. PAC-E-21-07, Order No. 35277 (Dec. 27, 2021).

Service Charge. For Schedule 36, only about eleven percent of revenue is recovered 1
through the Customer Service Charge. 2
Q. Why is this problematic? 3
A. The Company’s current rate structure for residential customers recovers a high 4
proportion of fixed costs through energy charges instead of through fixed charges. This 5
dynamic results in larger customers who use more energy subsidizing smaller 6
customers who use less energy. 7
Q. What costs does the Company propose be recovered by the Customer Service 8
Charge? 9
A. The Company proposes to recover all costs related to the distribution system and 10
customer service through the Customer Service Charge. It is appropriate to include 11
these costs in the fixed monthly charges that residential customers pay, because they 12
represent the fixed costs to the Company of delivering power on the distribution 13
system, providing a bill, and responding to customer inquiries. These costs are fixed in 14
nature and do not change with changes in volumetric energy usage. If a residential 15
customer uses more energy, that incremental usage will not cause the Company to 16
deploy more poles and wires or set more transformers, nor will the cost to answer phone 17
calls or send customers a bill change. These costs are therefore appropriately recovered 18
through the fixed Customer Service Charge. The Company proposes to recover all other 19
costs, production, and transmission costs, through Energy Charges. 20
Q. What Customer Service Charge does the Company propose for the end of the five-21
year transition? 22
A. The Company proposes that the Customer Service Charge be set at $29.25 for both 23

Meredith, Di-8
Rocky Mountain Power
Schedule 1 and Schedule 36. 1
Q. Why is the Company proposing the same Customer Service Charge for both 2
Schedule 1 and Schedule 36? 3
A. Schedule 1 and Schedule 36 presently have different Customer Service Charges, 4
because the metering cost has historically been higher for Schedule 36 customers who 5
require usage to be measured by time of day. With the Company’s deployment of 6
advanced metering infrastructure (“AMI”), this distinction in metering cost will no 7
longer exist, since any residence equipped with an AMI meter will be able to measure 8
usage by time of day. Additionally, Schedule 36 is an optional rate schedule that 9
residential customers can choose. Ideally, the Company would like residential 10
customers to opt into time of use, because they want the opportunity to save money by 11
shifting usage to off-peak periods, not because they could benefit as a larger user from 12
a rate design that recovers more costs in the Customer Service Charge than the Energy 13
Charge. Having the same Customer Service Charge for both Schedule 1 and Schedule 14
36 would prevent customers from choosing one schedule or the other based upon the 15
fixed charge/energy charge recovery dynamic. 16
Q. How does $29.25 per month compare to the basic charges for other electric utilities 17
in Idaho? 18
A. At $29.25 per month, the Company’s residential Customer Service Charge would be 19
within the same range of the fixed monthly rates that other Idaho electric utilities charge 20
residential customers. Table 1 below shows the fixed monthly residential charges for 21
all Idaho electric utilities with more than 1,000 customers: 22

Charges for Major Idaho Electric Utilities 2

Tiered Energy Charge 3
Q. Please explain how the Company’s current tiered energy charges work for 4
Schedule 1. 5
A. Schedule 1 customers are subject to seasonal inclining block tiered rates where the 6
price of energy is more expensive when a customer uses more than a given threshold 7
during a monthly billing period. Additionally, energy charges vary in price by season, 8
with higher energy pricing in the summer season of June through October and lower 9
pricing in the winter season of November through May. Table 2 shows the Company’s 10
current residential Schedule 1 energy charge prices: 11

Table 2. Schedule 1 Residential Energy Rates 1

Q. Historically, why were tiered energy charges implemented? 2
A. The inclining block rate structure has been used as a tool for encouraging customers to 3
use less energy. The theory is that the first block covers some basic level of usage at a 4
lower rate to help keep the overall bill affordable for customers and a second or third 5
block with a higher rate makes incremental energy usage more expensive to encourage 6
energy efficiency. For a customer with usage in the higher tier, making an energy 7
efficient choice like installing light emitting diode (“LED”) light bulbs would yield 8
greater savings than under a flat energy charge rate design. 9
Q. Do you believe that tiered energy charges encourage energy efficiency? 10
A. Not necessarily. As explained in more detail below, the total energy that a residential 11
customer uses during a month may vary based upon factors other than energy efficiency 12
like household size and fuel type. 13
Q. Why is the Company proposing to eliminate energy tiers and move to flat seasonal 14
rates for Schedule 1? 15
A. While well intentioned, tiered rates produce more problems than they solve because 16
they are not economically justified and unduly penalize customers. 17
Q. Please explain why tiered rates are not economically justified. 18
A. There is no cost-based reason why after using 700 kWh or 1,000 kWh in a given month 19
the next kWh consumed by a customer should cost more. On the other hand, the timing 20
June through October
1st 700 kWh 11.1966 ¢/kWh
All additional kWh 13.0999 ¢/kWh
November through May
1st 1,000 kWh 9.3305 ¢/kWh
All additional kWh 10.9165 ¢/kWh

Meredith, Di-11
Rocky Mountain Power
of energy consumption, both seasonally and during different hours, can affect the 1
utility’s cost of providing service to the customer. Similarly, the load factor or the 2
effective utilization of kWh consumption relative to peak kilowatt demand can also 3
change the average cost of providing energy. However, additional overall usage in a 4
monthly billing period does not make it incrementally more expensive for the utility to 5
produce that next kWh of electricity. 6
Q. Please explain why tiered rates unduly penalize customers. 7
A. Charging higher prices for greater usage in a given month causes larger users to 8
subsidize smaller users. Under a tiered rate structure, customers who heat their home 9
with natural gas benefit and those who use electric heat are punished. A large household 10
with a lot of people living under one roof will be more likely to have usage in the higher 11
second block rate than a person living alone. Effectively, inclining block rates unfairly 12
reward some customers and punish others, often for reasons outside the customer’s 13
control. 14
Q. Do you have any evidence that specific groups of residential customers tend to use 15
more energy per month? 16
A. Yes. In 2021, the Company conducted an email survey of its customers and collected 17
end use and demographic information from participants. Using this information and 18
comparing the household size indicated by the respondent to average monthly usage at 19
the site, the Company found that there is a clear trend of greater usage for larger 20
household size in the Company’s Idaho service territory. Table 3 shows this finding: 21

Meredith, Di-12
Rocky Mountain Power
Table 3. Usage by Household Size 1
from the 2021 Residential Email Survey 2

The Company’s survey information also indicated that usage is considerably higher for 3
customers who utilize electricity as their main source of heating equipment compared 4
to other fuels. Table 4 shows this information: 5
Table 4. Usage by Fuel for Main Source of Heating 6
Equipment from the 2021 Residential Email Survey 7

In summary, the total energy that a residential customer uses during a month may vary 8
based upon factors other than energy efficiency like household size and fuel type. 9
Penalizing customers with a higher cost per kWh for usage in excess of a threshold is 10
unfair and not supported by cost causation. 11
Q. Is there another reason why eliminating tiers from Schedule 1 is advantageous? 12
A. Yes. As I indicated earlier in my testimony, ideally a customer’s decision to opt into 13
the voluntary Schedule 36 time of use program would be motivated by a desire to shift 14
load to lower cost times instead of to take advantage of a rate structure that favors larger 15
users. Eliminating tiers for Schedule 1 makes the comparison to Schedule 36, which 16
does not have tiers, easier for customers to assess regarding the potential benefits of 17

time varying pricing. 1
Time of Use 2
Q. What are the current time of use periods for Schedule 36 and what changes does 3
the Company propose? 4
A. Presently, the on-peak period for Schedule 36 is weekdays from 8 A.M. to 11 P.M. 5
during summer months and from 7 A.M. to 10 P.M. during winter months excluding 6
holidays. The off-peak period is during all other times. The summer season is defined 7
as May through October and the winter season is defined as November through April. 8
In the 2021 Rate Case, the month of May was reclassified as a lower cost winter month 9
for most other rate schedules, but not for Schedule 36 because such a change would 10
entail reprogramming meters and did not make sense with AMI deployment close on 11
the horizon. 12
The Company is proposing that, in the third year of the Residential Rate 13
Modernization Plan, the time of use definitions for Schedule 36 be changed to those 14
used for Schedule 9. Specifically, the on-peak period would be every day from 3 P.M. 15
to 11 P.M. during the summer months and from 6 A.M. to 9 A.M and again from 6 P.M. 16
to 11 P.M. during the winter months. The seasonal definition would be revised so that 17
the month of May would move to the lower cost winter season. 18
Q. Why is the Company proposing to change the time of use periods for Schedule 36? 19
A. The time of use periods for Schedule 36, that have been in place since the early 1980’s, 20
are no longer reflective of costs and use a long 15-hour period of time during non-21
holiday weekdays for the on-peak period. The Company is proposing to change the 22
time of use periods to a shorter window of time for the on-peak period that better 23

Meredith, Di-14
Rocky Mountain Power
reflects times when it is more costly for the Company to serve. This more focused on-1
peak period would give customers a better price signal to prioritize the more critical 2
times when they should shift load. 3
Q. Why did the Company select these particular on-/off-peak periods for Schedule 4
36? 5
A. In the 2021 Rate Case, the Company identified these hours as the times during both 6
seasons when the Energy Imbalance Market (“EIM”) pricing was the highest and used 7
them to set time varying pricing definitions that are currently in place for Schedule 9. 8
This analysis was conducted recently, and the Company does not believe that a more 9
current evaluation is necessary. 10
Q. Why is the Company proposing that this change take place in the third year of the 11
transition plan? 12
A. While AMI deployment is well underway, it is not yet completed. Waiting until AMI 13
is deployed is important, because AMI meters can be re-programmed to use new time 14
of use periods remotely without the need to send a truck to the site and have a meterman 15
physically re-program the meter. Additionally, the time of use periods for Schedule 36 16
have been in place for a very long period of time. The Company is therefore requesting 17
that this change occurs in the third year of the transition, so that AMI will be fully 18
deployed, and the Company will have an opportunity to properly notify customers of 19
the change. 20

Rate Design Calculations 1
Q. What prices does the Company propose for Schedule 1 and Schedule 36 for the 2
five-year Residential Rate Modernization Plan? 3
A. Exhibit No. 2 shows the proposed prices, billing determinants, and anticipated revenue 4
for the Residential Rate Modernization Plan. The anticipated residential revenue for 5
each year of the transition is the same, demonstrating that the Company’s proposed 6
prices are revenue neutral. In each successive year of the transition period, the 7
Customer Service Charge increases and revenue from Energy Charges decreases. 8
Additionally, for Schedule 1, the difference between the first and second block Energy 9
Charges decreases in each transition year until tiered rates are eliminated in the final 10
transition. Table 5 summarizes the proposed prices for Schedule 1 for each year of the 11
transition: 12

Table 6. Proposed Schedule 36 Prices by Transition Year 2
3
Q. How were prices for the five-year Residential Rate Modernization transition 4
calculated? 5
A. The $29.25 Customer Service Charge was calculated by taking residential revenue 6
from both Schedule 1 and Schedule 36 and multiplying by the proportion of cost of 7
service related to all other fixed costs besides production and transmission costs and 8
dividing by the count of monthly Customer Service Charges. This value was rounded 9
to the nearest quarter of a dollar. To determine prices for the transition, the Customer 10
Service Charge was increased by one fifth of the difference between the present 11
Customer Service Charge and $29.25 in each year of the transition. 12
In the final transition year for Schedule 1, flat seasonal Energy Charges were 13
determined by maintaining the present seasonal differential of 20 percent and solving 14
for the remaining revenue required for the class after removing the proposed Customer 15
Charge revenue. Prices for each transition year were determined by decreasing the 16
energy charge by one fifth of the difference between the present and final transition 17

year price in each subsequent period. 1
To determine proposed Schedule 36 Energy Charges, the final transition year 2
off-peak energy charges were set at a level that was proportionately lower to reflect the 3
increase in the recovery from the higher Customer Service Charge. Off-peak energy 4
charges were calculated for each year of the transition similar to how Schedule 1 5
Energy Charges during the transition were determined with the off-peak energy charges 6
being set for each year of the transition by decreasing by one fifth of the difference 7
between final and present off-peak energy charges for each subsequent period. The on-8
peak energy charges were calculated by solving for the prices required to make up the 9
remaining revenue needed for the class while maintaining the same relative seasonal 10
differential. In the third year of the transition, the billing determinants for on- and off-11
peak energy were modified to reflect the change in the time of use definitions. On- and 12
off-peak energy from the new time of use periods were estimated from hourly load 13
research information. 14
Customer Bill Impacts 15
Q. How would the Company’s proposed Residential Rate Modernization impact 16
customers at different usage levels? 17
A. Exhibit No. 3 shows bill comparisons for the proposed transition. Page one of Exhibit 18
No. 3 shows a bill comparison table, similar to the ones the Company uses in rate cases, 19
for the bill impact of the first year of the transition for Schedule 1 customers across 20
different usage levels. The largest increase across the different usage levels shown is a 21
$3.88 per month increase for a customer using 100 kWh. Page two shows the same 22
thing, but for the change over the entire transition. The largest increase for the usage 23

Meredith, Di-18
Rocky Mountain Power
levels shown for the entire transition is $19.38 per month for the same typical customer 1
using 100 kWh per month. The difference between these values demonstrates the need 2
to make the changes in price over the requested five-year period to moderate customer 3
impacts. Pages three and four of Exhibit No. 3 show the same information, except for 4
the proposed transition for Schedule 36. 5
Q. Did the Company prepare an analysis that examines the impact on individual 6
customers that would result from the Company’s proposed Residential Rate 7
Modernization Plan? 8
A. Yes. Page five of Exhibit No. 3 shows the distribution of impacts across Schedule 1 9
customers examining their actual monthly usages for the first-year price change of the 10
transition. Page six of Exhibit No. 3 shows the same thing but expressed in percentage 11
terms. Pages seven and eight of Exhibit No. 3 show the same analysis as is presented 12
on pages five and six, but for the price change across the entire five-year transition. 13
Pages nine through 12 show the same estimated bill impact distribution analysis for 14
Schedule 36 customers. Hourly usage for individual Schedule 36 customers is not 15
available, so the impacts shown assume that each Schedule 36 customer has the average 16
profile estimated from load research. The analysis of the customer impact distributions 17
shows that for the majority of customers, the monthly impact of the Company’s 18
proposal will be very modest. 19
Customer Outreach 20
Q. Does the Company plan to do any customer outreach for its proposal? 21
A. Yes. In addition to the usual customer noticing required for rate changes, the Company 22
plans to host two customer outreach events where customers can provide feedback to 23

Meredith, Di-19
Rocky Mountain Power
and ask questions of Company personnel about the Residential Rate Modernization 1
Plan. The Company plans to schedule these events after a procedural schedule is 2
established for this filing. 3
Conclusion 4
Q. What is your recommendation to the Commission? 5
A. I recommend that the Commission approve the Company’s Residential Rate 6
Modernization Plan with its associated tariff revisions. 7
Q. Does this conclude your direct testimony? 8
A. Yes. 9

______________
Residential Service ______________
AVAILABILITY: At any point on the Company's interconnected system where there are facilities
of adequate capacity.
APPLICATION: This Schedule is for alternating current electric service supplied at approximately
120 or 240 volts through one kilowatt-hour meter at a single point of delivery for all service required on the premises for Residential purposes.
When conditions are such that service is supplied through one meter to more than one dwelling or apartment unit, the charge for such service will be computed by multiplying the minimum charges by the maximum number of dwelling or apartment units that may be served.
When a portion of a dwelling is used regularly for business, professional or other gainful purposes, the premises will be classified as nonresidential and the appropriate schedule applied. However, if the
wiring is so arranged that the service for Residential purposes can be metered separately, this Schedule will be applied to such service.
