Errata Filing
Dear Ms. Noriyuki:
On October 20,2022, Rocky Mountain Power (the "Company") submitted its Application and
direct testimony of Robert M. Meredith in the above-referenced matter. Since that submission, the
Company was made aware of an error on the header of table 5 and table 6 on page l5 and page l6
of Mr. Meredith's direct testimony. The tables have been corrected to "cents per kWh" to match
the units of measurement in the remainder of the testimony. The Company hereby submits the
corrected pages from Mr. Meredith's testimony followed by a corrected and clean copy of the
entire application.
Informal inquiries may be directed to Ted Weston, Idaho Regulatory Manager at (801) 220-
2963.
Sincerely
R.

a. What prices does the Company propose for Schedule I and Schedule 36 for the
Iive-year Residential Rate Modernization Plan ?
A. ExhibitNo. 2 shows the proposed prices, billing determinants, and anticipated revenue
for the Residential Rate Modernization Plan. The anticipated residential revenue for
each year of the transition is the same, demonstrating that the Company's proposed
prices are revenue neutral. In each successive year of the transition period, the
Customer Service Charge increases and revenue from Energy Charges decreases.
Additionally, for Schedule l, the difference between the first and second block Energy
Charges decreases in each transition year until tiered rates are eliminated in the final
transition. Table 5 summarizes the proposed prices for Schedule I for each year of the
transition:

How were prices for the five-year Residential Rate Modernization transition
calculated?
The $29.25 Customer Service Charge was calculated by taking residential revenue
from both Schedule I and Schedule 36 and multiplying by the proportion of cost of
service related to all other fixed costs besides production and transmission costs and
dividing by the count of monthly Customer Service Charges. This value was rounded
to the nearest quarter of a dollar. To determine prices for the transition, the Customer
Service Charge was increased by one fifth of the difference between the present
Customer Service Charge and $29.25 in each year of the transition.
In the final transition year for Schedule l, flat seasonal Energy Charges were
determined by maintaining the present seasonal differential of 20 percent and solving
for the remaining revenue required for the class after removing the proposed Customer
Charge revenue. Prices for each transition year were determined by decreasing the
energy charge by one fifth of the difference between the present and final transition

IN TIIE MATTER OF THE APPLICATION
OF ROCKY MOI]NTAIN POWER FOR
AUTHORITY TO IMPLEMENT THE
RESIDENTIAL RATE MODERNIZATION
PLAN
CASE NO. PAC.E-22-I5
APPLICATION
Rocky Mountain Power, a division of PacifiCorp (the o'Company"), hereby petitions

5. This Application seeks Commission approval of the Residential Rate
Modernization Plan. The Residential Rate Modernization Plan proposes to modiff residential
rates over a five-year transition period in the following ways:
a) Increase the Customer Service Charge for both Electric Service Schedule No. I
- Residential Service ("Schedule l") 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 l, so that Energy Charges
are flat in each season.
4.
APPLICATION OF
ROCKY MOTINTAIN POWER
Page2
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 Modemization 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. I 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
ROCKY MOUNTATN POWER
Page 3
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 I 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 I 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 I
customers are subject to seasonal inclining block tiered rates that are not economically justified
and unduly penalize certain customers. Eliminating tiered rates from Schedule I 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 Modemization 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
ROCKY MOUNTATN POWER
Page 4
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.
I I . In accordance with Commission Rule l2 I .0 I (g), Rocky Mountain Power's
system-wide costs were allocatedl to Idaho based on the approved 2020PacifiCorp Inter-
Juri sdictional Al location Protoco I (" 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. I 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.

For release Ocl,.20,2022 FINAI DRAFI, rev. 10-20-22,9 a.m. MDT
Changes proposed to modernize residential rates
New prices would better reflect costs ond enhonce foirness
BOISE - Rocky Mountain Power has proposed updated rates for residential customers to the ldaho
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. 35 - OptionalTime-of-Day Residential Service.
lmportantly, 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 58 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 58 to 512.25 for Schedule 1, with subsequent changes annually for the next four years.
These changes must be approved by the ldaho Public Utilities Commission.
The five-year transition to a more accurate customer service charge is in line with what other ldaho
electric utilities charge. A survey of fixed monthly charges for residential customers from 11 other
utilities shows that the average is about S23 per month, and ranges from 55 to S40.
ln 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 customerc, and how energy charges would be reduced
accordingly.

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 custome/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 proposes to modernize residential prices
On October 20,2022, Rocky Mountain Power flled a request
with the ldaho 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-houn The utility proposes a gradual transition over
flve 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. 35 - 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 $1 2.25 for Schedule 1, with subsequent
changes annually for the next four years. These changes must be

residential rates in the following ways:
l. Increase the Customer Service Charge for both Electric Service Schedule No. I -
Residential Service ("Schedule l") and Electric Service Schedule No. 36 - Optional
Time of Day - Residential Service ("Schedule 36") to $29.25 per month and lower
Energy Charges commensurately. If the Company files a general rates case during
the Residential Rate Modernization Plan the rates in this application would be
updated to reflect any Commission approved rate changes.
2. Eliminate inclining block tiered rates for Schedule l, so that Energy Charges are
flat in each season.
3. Change the time of use periods in Schedule 36, so that the definitions of on- and
off-peak periods match those listed on Electric Service Schedule No. 9 - General
Service - High Voltage ("Schedule 9").
When does the Company propose these changes occur?
The Company proposes that the first price change occur on December l, 2022.
Subsequent price changes would take effect on December I with the final change of
the transition occurring on December 1,2026.
Has the Company provided proposed revised tariffs for these changes?
Yes. Exhibit No. 5 contains proposed tariffrevisions to Schedules I and 36.
Are the proposed tariff revisions to Schedules 1 and 36 revenue neutral for the
Company?
Yes. The Residential Rate Modernization Plan is revenue neutral and does not modify
the Company's revenue requirement.

I Q. How does the Company propose the Residential Rate Modernization Plan would
2 operate if the Company had a general rate case in the intervening years of the
3 transition period?
4 A. If there is a base rate change for residential customers as the result of a general rate
5 case, the Company proposes that the current residential prices at that time as well as
6 the prices laid out for subsequent transition periods would all change by an equal
7 percentage, so that the transition can proceed in an orderly manner.
8 Residential Rate Modernization Plan Rationale
9 Q. Why is the Company making this proposal?
l0 A. The Company's current residential rate structure does not adequately reflect cost
I I causation. The electric utility industry requires a significant amount of capital
12 infrastructure, which is largely a fixed cost once infrastructure goes into service. The
13 current residential rate structure is comprised of the Customer Service Charge, which
14 is a monthly fixed charge, and energy charges, which are usage- based or volumetric
15 charges. The Customer Service Charge falls far short of covering the fixed costs that
16 are incurred by residential customers and those fixed costs are therefore recovered
17 through volumetric energy charges. Energy Charges in Schedule I are also tiered, so
18 that usage over a specific threshold in a monthly billing period gets priced at a higher
19 rate. The effect of a low Customer Service Charge and tiered energy charges is that
20 customers with low monthly usage are subsidized by customers with higher monthly
2l usage. For Schedule 36, which is an optionaltime of use rate schedule, the time of use
22 period definitions have been the same for several decades, since the schedule's
23 inception in the early 1980's. The Company proposes modifuing those definitions to

better reflect the hourly differences in the Company's cost of providing energy.
Why isn't the Company proposing to make these changes in general rate cases?
The Residential Rate Modernization Plan includes a five-year transition to gradually
update rate design. Progress was made in the Company's most recent general rate case,
Case No. PAC-E-21-07 (*2021 Rate Case"), where the Company proposed and the
Commission approved an increase to the residential Customer Service Charge from $5
per month to $8 per month and a partial flattening of tiered Energy Charges. However,
rate cases historically have not been filed very often and prior to the 2021 Rate Case,
it had been about ten years since the Company's last case in20ll, Case No. PAC-E-
ll-12. Further, a host of different issues are raised in general rate cases which can make
it challenging to make significant progress on rate design. In order to facilitate a
transition, the Company is requesting these changes to residential rates now so that the
intraclass subsidies between large and small users can be resolved sooner in this
proceeding, rather than in a future general rate case, and so that the other issues that
arise in a general rate case will not distract from progress on this important topic.
Why is the Company proposing that these changes occur over a five-year
transition?
The Company is proposing that residential rates be modified gradually over this
timeframe to moderate bill impacts on individual customers. While it is important to
make these changes to better align rates with the cost of service, this must be balanced
with how these changes affect some customers. I will describe later in my testimony
the billing impact distribution of the price changes and why the Company's proposal
achieves this balance.

6 A. For Schedule l, the Customer Service Charge is presently $8 per month.l For Schedule
7 36, it is $15 per month.

9 costs?
l0 A. On average, the cost of service for a residential customer is $97.32 per month. $22.84
I I or about 23 percent of this value is energy related. The remaining $74.48 or about 77
12 percent is fixed and not energy related. Exhibit No. I shows in greater detail how cost
13 of service breaks down by category for Schedule l, Schedule 36, and for all residential
14 customers in total. To develop this exhibit and subsequent exhibits and pricing analysis

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

Schedule I and Schedule 36.
Why is the Company proposing the same Customer Service Charge for both
Schedule 1 and Schedule 36?
Schedule I and Schedule 36 presently have different Customer Service Charges,
because the metering cost has historically been higher for Schedule 36 customers who
require usage to be measured by time of day. With the Company's deployment of
advanced metering infrastructure ("AMI"), this distinction in metering cost will no
longer exist, since any residence equipped with an AMI meter will be able to measure
usage by time of day. Additionally, Schedule 36 is an optional rate schedule that
residential customers can choose. Ideally, the Company would like residential
customers to opt into time of use, because they want the opportunity to save money by
shifting usage to off-peak periods, not because they could benefit as a larger user from
a rate design that recovers more costs in the Customer Service Charge than the Energy
Charge. Having the same Customer Service Charge for both Schedule I and Schedule
36 would prevent customers from choosing one schedule or the other based upon the
fixed charge/energy charge recovery dynamic.
How does $29.25 per month compare to the basic charges for other electric utilities
in ldaho?
At $29.25 per month, the Company's residential Customer Service Charge would be
within the same range ofthe fixed monthly rates that other Idaho electric utilities charge
residential customers. Table I below shows the fixed monthly residential charges for
all Idaho electric utilities with more than 1,000 customers:

6 A. Schedule I customers are subject to seasonal inclining block tiered rates where the
7 price of energy is more expensive when a customer uses more than a given threshold
8 during a monthly billing period. Additionally, energy charges vary in price by season,
9 with higher energy pricing in the summer season of June through October and lower
l0 pricing in the winter season of November through May. Table 2 shows the Company's

Historically, why were tiered energy charges implemented?
The inclining block rate structure has been used as a tool for encouraging customers to
use less energy. The theory is that the first block covers some basic level of usage at a
lower rate to help keep the overall bill affordable for customers and a second or third
block with a higher rate makes incremental energy usage more expensive to encourage
energy efficiency. For a customer with usage in the higher tier, making an energy
efficient choice like installing light emitting diode ("LED") light bulbs would yield
greater savings than under a flat energy charge rate design.
Do you believe that tiered energy charges encourage energy efficiency?
Not necessarily. As explained in more detail below, the total energy that a residential
customer uses during a month may vary based upon factors other than energy efficiency
like household size and fuel type.
Why is the Company proposing to eliminate energy tiers and move to flat seasonal
rates for Schedule 1?
While well intentioned, tiered rates produce more problems than they solve because
they are not economically justified and unduly penalize customers.
Please explain why tiered rates are not economically justified.
There is no cost-based reason why after using 700 kWh or 1,000 kwh in a given month
the next kWh consumed by a customer should cost more. On the other hand, the timing

of energy consumption, both seasonally and during different hours, can affect the
utility's cost of providing service to the customer. Similarly, the load factor or the
effective utilization of kWh consumption relative to peak kilowatt demand can also
change the average cost of providing energy. However, additional overall usage in a
monthly billing period does not make it incrementally more expensive for the utility to
produce that next kWh of electricity.
Please explain why tiered rates unduly penalize customers.
Charging higher prices for greater usage in a given month causes larger users to
subsidize smaller users. Under a tiered rate structure, customers who heat their home
with natural gas benefit and those who use electric heat are punished. A large household
with a lot of people living under one roof will be more likely to have usage in the higher
second block rate than a person living alone. Effectively, inclining block rates unfairly
reward some customers and punish others, often for reasons outside the customer's
control.
Do you have any evidence that specific groups of residential customers tend to use
more energy per month?
Yes. In 202l,the Company conducted an email survey of its customers and collected
end use and demographic information from participants. Using this information and
comparing the household size indicated by the respondent to average monthly usage at
the site, the Company found that there is a clear trend of greater usage for larger
household size in the Company's Idaho service territory. Table 3 shows this finding:
Meredith, Di-l I
Rocky Mountain Power
I
2
Table 3. Usage by Household Size
from the 2021 Residential Email Su
The Company's survey information also indicated that usage is considerably higher for
customers who utilize electricity as their main source of heating equipment compared
to other fuels. Table 4 shows this information:
Table 4. Usage by Fuel for Main Source of Heating
from the 2021 Residential Email
ln summary, the total energy that a residential customer uses during a month may vary
based upon factors other than energy efficiency like household size and fuel type.
Penalizing customers with a higher cost per kWh for usage in excess of a threshold is
unfair and not supported by cost causation.
O. Is there another reason why eliminating tiers from Schedule 1 is advantageous?
A. Yes. As I indicated earlier in my testimony, ideally a customer's decision to opt into
the voluntary Schedule 36 time of use program would be motivated by a desire to shift
load to lower cost times instead of to take advantage of a rate structure that favors larger
users. Eliminating tiers for Schedule I makes the comparison to Schedule 36, which
does not have tiers, easier for customers to assess regarding the potential benefits of

2 Time of Use
3 Q. What are the current time of use periods for Schedule 36 and what changes does
4 the Company propose?
5 A. Presently, the on-peak period for Schedule 36 is weekdays from 8 A.M. to I I P.M.
6 during summer months and from 7 A.M. to l0 P.M. during winter months excluding
7 holidays. The off-peak period is during all other times. The summer season is defined
8 as May through October and the winter season is defined as November through April.
9 I n the 2021 Rate Case, the month of May was reclassified as a lower cost winter month
l0 for most other rate schedules, but not for Schedule 36 because such a change would
I I entail reprogramming meters and did not make sense with AMI deployment close on
12 the horizon.
13 The Company is proposing that, in the third year of the Residential Rate
14 Modernization Plan, the time of use definitions for Schedule 36 be changed to those
15 used for Schedule 9. Specifically, the on-peak period would be every day from 3 P.M.
l6 to I I P.M. during the summer months and from 6 A.M. to 9 A.M and again from 6 P.M.
17 to I I P.M. during the winter months. The seasonal definition would be revised so that
l8 the month of May would move to the lower cost winter season.
19 a. Why is the Company proposing to change the time of use periods for Schedule 36?
20 A. The time of use periods for Schedule 36, that have been in place since the early 1980's,
2l are no longer reflective of costs and use a long l5-hour period of time during non-
22 holiday weekdays for the on-peak period. The Company is proposing to change the
23 time of use periods to a shorter window of time for the on-peak period that better

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

Rate Design Calculations
a. What prices does the Company propose for Schedule I and Schedule 36 for the
five-year Residential Rate Modernization Plan?
A. ExhibitNo. 2 shows the proposed prices, billing determinants, and anticipated revenue
for the Residential Rate Modernization Plan. The anticipated residential revenue for
each year of the transition is the same, demonstrating that the Company's proposed
prices are revenue neutral. [n each successive year of the transition period, the
Customer Service Charge increases and revenue from Energy Charges decreases.
Additionally, for Schedule 1, the difference between the first and second block Energy
Charges decreases in each transition year until tiered rates are eliminated in the final
transition. Table 5 summarizes the proposed prices for Schedule 1 for each year of the
transition:

How were prices for the five-year Residential Rate Modernization transition
calculated?
The $29.25 Customer Service Charge was calculated by taking residential revenue
from both Schedule I and Schedule 36 and multiplying by the proportion of cost of
service related to all other fixed costs besides production and transmission costs and
dividing by the count of monthly Customer Service Charges. This value was rounded
to the nearest quarter of a dollar. To determine prices for the transition, the Customer
Service Charge was increased by one fifth of the difference between the present
Customer Service Charge and$29.25 in each year of the transition.
In the final transition year for Schedule l, flat seasonal Energy Charges were
determined by maintaining the present seasonal differential of 20 percent and solving
for the remaining revenue required for the class after removing the proposed Customer
Charge revenue. Prices for each hansition year were determined by decreasing the
energy charge by one fifth of the difference between the present and final transition

I year price in each subsequent period.
2 To determine proposed Schedule 36 Energy Charges, the final transition year
3 off-peak energy charges were set at a level that was proportionately lower to reflect the
4 increase in the recovery from the higher Customer Service Charge. Off-peak energy
5 charges were calculated for each year of the transition similar to how Schedule I
6 Energy Charges during the transition were determined with the off-peak energy charges
7 being set for each year ofthe transition by decreasing by one fifth ofthe difference
8 between final and present off-peak energy charges for each subsequent period. The on-
9 peak energy charges were calculated by solving for the prices required to make up the
l0 remaining revenue needed for the class while maintaining the same relative seasonal
I I differential. In the third year of the transition, the billing determinants for on- and off-
12 peak energy were modified to reflect the change in the time of use definitions. On- and
13 off-peak energy from the new time of use periods were estimated from hourly load
14 research information.
l5 Customer Bill Impacts
16 a. How would the Companyos proposed Residential Rate Modernization impact
17 customers at different usage levels?
l8 A. Exhibit No. 3 shows bill comparisons for the proposed transition. Page one of Exhibit
l9 No. 3 shows a bill comparison table, similar to the ones the Company uses in rate cases,
20 for the bill impact of the first year of the transition for Schedule I customers across
2l different usage levels. The largest increase across the different usage levels shown is a
22 $3.88 per month increase for a customer using 100 kwh. Page two shows the same
23 thing, but for the change over the entire transition. The largest increase for the usage
Meredith, Di-17
Rocky Mountain Power
I levels shown for the entire transition is $ I 9.38 per month for the same typical customer
2 using 100 kWh per month. The difference between these values demonstrates the need
3 to make the changes in price over the requested five-year period to moderate customer
4 impacts. Pages three and four of Exhibit No. 3 show the same information, except for
5 the proposed transition for Schedule 36.
6 Q. Did the Company prepare an analysis that examines the impact on individual
7 customers that would result from the Company's proposed Residential Rate
8 Modernization Plan?
9 A. Yes. Page five of Exhibit No. 3 shows the distribution of impacts across Schedule I
l0 customers examining their actual monthly usages for the first-year price change of the
I I transition. Page six of Exhibit No. 3 shows the same thing but expressed in percentage
12 terms. Pages seven and eight of Exhibit No. 3 show the same analysis as is presented
13 on pages five and six, but forthe price change across the entire five-yeartransition.
14 Pages nine through 12 show the same estimated bill impact distribution analysis for
15 Schedule 36 customers. Hourly usage for individual Schedule 36 customers is not
16 available, so the impacts shown assume that each Schedule 36 customer has the average
17 profile estimated from load research. The analysis of the customer impact distributions
18 shows that for the majority of customers, the monthly impact of the Company's
19 proposal will be very modest.
20 Customer Outreach
2l a. Does the Company plan to do any customer outreach for its proposal?
22 A. Yes. In addition to the usual customer noticing required for rate changes, the Company
23 plans to host two customer outreach events where customers can provide feedback to

ELECTRIC SERVICE SCHEDULE NO. 1
STATE OF IDAHO
Residential Service
AVAILABILITY: At any point on the Company's interconnected system where there are facilities
ofadequate 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.

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.
