CUSTOMER ON.SITE GENERATION
CASE NO. IPC-E-21-21
APPLICATION
ldaho Power Company ("ldaho Power" or "Company"), in response to the ldaho
Public Utilities Commission's ("Commission") directive in Order No. 34046,1 respectfully
requests that the Commission initiate the multi-phase process for a comprehensive study
of the costs and benefits of on-site generation. ldaho Power further requests the
Commission acknowledge Attachment 1 as an initial draft for Staff, other intervenors, and
the public to consider and provide feedback on for the Commission's consideration.
Ultimately, the Company requests the Commission to approve a final scoping document,
which will conclude the "study design" phase.
ln support of this Application, ldaho Power asserts as follows:

I. BACKGROUND
On-Site Generation
1. Some retail customers choose to install "on-site generation" equipment,
most commonly solar panels, to meet some or all of their electric needs. While generating
electricity on-site, these customers are also simultaneously connected in parallelto ldaho
Power's grid and the vast majority export energy to the grid. Customers who install on-
site generation can interconnect an Exporting System under the terms of Schedule 6,
Residential Service On-Site Generation ("Schedule 6"), Schedule 8, Small General
Service On-Site Generation ("Schedule 8"), Schedule 68, lnterconnections to Customer
Distributed Energy Resources ("Schedule 68") and Schedule 84, Customer Energy
Production Net Metering Service ("Schedule 84"). Customers who installa Non-Exporting
System continue to take service under the retail rate schedule they qualiff for based on
the applicability of the Company's retail tariff schedules. All customers with on-site
generation are subject to the terms of Schedule 68 governing interconnection.
2. As of May 31 ,2021, there are 7,789 Exporting Systems interconnected and
taking service under Schedules 6, 8, and 84 and three (3) Non-Exporting Systems
interconnected and taking service under Schedules I and 19. Collectively, these
customer systems represent approximately 70 MW of generation,
Billino Structure
3, The billing structure currently applicable to these schedules is referred to as
"net metering." Under the net metering compensation structure, if electricity supplied by
the Company during a Billing Period exceeds the electricity generated by the Customer
and delivered to the Company during the Billing Period, the Customer is billed for the net
electricity supplied by the Company at the rates contained within the applicable service
schedule. lf the electricity generated by the Customer and delivered to the Company
during the Billing Period exceeds the electricity supplied by the Company during the
APPLICATION - 2
Billing Period, the Excess Net Energy is carried forward as a kilowatt-hour ("k\A/h") credit
to offset energy usage in a subsequent Billing Period, These customers could also be
referred to as "partial requirements" customers because they are offuetting some or all of
their usage with their own generation.
4. ldaho Power's current retail rates were designed to align with the load
characteristics of full requirements customers. A large portion of the Company's revenue
requirement is collected through volumetric energy rates, including costs associated with
all components of the electrical system, from investment in generation resources to the
meters installed on customers' premises. Consequently, the energy rates for ldaho
Power's customers include not only the variable energy-related components of the
revenue requirement, but also the fixed operations and maintenance and plant-related
costs associated with generation, transmission, distribution, and customer care.
5. Because fixed costs do not vary with changes in the amount of energy
consumed from Idaho Power, a volumetric rate does not fully recover fixed costs
associated with customers who offset their consumption with on-site generation. The
Company's residential and small general service (.R&SGS") customers have the most
significant portion of fixed costs - 91 percent2 - collected through those schedules'
volumetric charge. The Company's large general service (commercial), industrial, and
irrigation customer classes ("Cl&|" customers) have 60, 39, and 70 percent, respectively,
of each schedule's fixed costs collected through the volumetric charges.
6. To more accurately assign the appropriate share of fixed costs and
unquantified benefits of on-site generation, in Order No. 34046 the Commission directed
the Company to (1) "undertake a comprehensive study of fixed costs" and (2) "initiate a
docket to comprehensively study the costs and benefits of on-site generation on ldaho

Company's most recent general rate case, Case No. IPC-E-I1-08.
APPLICATION .3
Powe/s system, as well as proper rates and rate design, transitional rates, and related
issues of compensation for net excess energy provided as a resource to the Company.'3
Case No. IPC-E-18-15
7. ln Order No. 34509 the Commission directed ldaho Power to prepare and
file a "credible and fair study" of the costs and benefits of distributed on-site generation
where: (1) the study must use the most current data possible and must be readily
available to the public, and in the Commission's decision-making record; (2) the Company
must design the study in coordination with the parties and the public, and the Commission
will determine the final scope of the study; (3) the study must be written, so it is
understandable to an average customer, but its analysis must be able to withstand expert
scrutiny.a
8. ln its Order, the Commission outlined a "study design" phase and a "study
review" phase. During the "study design" phase, Staff and the Company will both "host
public workshops to share information and perspectives on net-metering program design
with the public and to listen to customer concerns and input."s ln the "study review"
phase, the public will have the opportunity to comment on whether the study sufficiently
addressed their concerns and their opinions on what the study shows.
9. While the study is intended to inform future implementation of on-site
generation compensation and billing structures, the Commission's order established
criteria6 to define legacy treatment for systems under Schedule 6 and Schedule 8. The

legacy systems would be subject to the rules in place as of the service date of Order No.
34509, December 20,2019. A legacy system is defined as either an on-site generation
system interconnected with ldaho Power's system as of the service date of Order No.
34509, or a customer with a binding financial commitment to install an on-site generation
system that proceeds to interconnect their system on or before December 20,2020.7
While legacy systems operate under the terms of Schedule 6 or Schedule 8 as those
Schedules existed on December 20, 2019, rates and rate structure are subject to change
for legacy systems until and after legacy status terminates on December 20, 2M5.8 As
of May 31, 2021, there are 5,400 legacy R&SGS systems interconnected to ldaho
Powe/s system.
Case No. IPC-E-20-26
10. To determine legacy treatment for Cl&l customers, the Company initiated
Case No. IPC-E-20-26 for authorization to change Schedule 84's two-meter requirement
to a single-meter requirement for new customer-generators and to establish legacy
treatment for existing customer-generators under the current rules as of December 1,
2020. The Commission ultimately established criteria similar to Case No. IPC-E-18-15,
to provide legacy treatment to Schedule 84 systems under the rules in place as of the
service date of Order No. 34854.e
11. The Commission's Order Nos. 34854 and 34892 delineated between legacy
systems and new systems subject to future changes informed by a comprehensive study.
A legacy system is defined as either an on-site generation system interconnected with
ldaho Power's system as of the service date of Order No. 34854, or a customer with a

binding financial commitment to instal! an on-site generation system that proceeds to
interconnect their system on or before December 1,2021.1o
12. Similar to Case No. IPC-E-18-15, the Commission determined that
Schedule 84 systems that qualify for legacy treatment continue to be subject to changes
in consumption rates but not to changes in the 1:1 monthly k\A/tr retail rate compensation
structure until legacy status terminates on December 1,2045.11 As of May 31 ,202'1,
there are 302 legacy Schedule 84 systems interconnected to ldaho Power's system.
II. STUDY DESIGN PHASE: IDAHO POWER,S PROPOSED SCOPE
13. The Company's primary objective of the study process is to establish a
sustainable on-site generation offering that limits subsidies by implementing a more
equitable pricing and compensation structure. The multi-phase study process will be
accomplished through a transparent and collaborative approach with stakeholders and
the public. Ultimately, the Company anticipates proposals to implement changes to the
on-site generation offering will be informed by the studies and should seek to eliminate
or minimize potentialcross-subsidies that exist between participants and non-participants
of on-site generation through rate design and compensation structures for on-site
generation customers. Further, the Company believes recommendations to modify the
existing offering should focus on cost-of-service principles, while identifying the
appropriate value of excess net energy to ensure equitable compensation for on-site
generators.
14. ln compliance with Commission Order No. 34509, the Company has
developed a draft scope of an on-site generation study for public review and input. The
draft scope is included as Attachment 1. To develop the draft scope of the study design
la ln the Matter of ldaho Power Company's Application to Modify Schedule 84's Meteing Requirement
and to Grandfather Existing Customers with Two Meters, Case No. IPC-E-z}-2fl Order No. 34892 at 9
(January 14,20211.
11 Order No. 34854 at 11.
APPLICATION .6
the Company leveraged information developed in the studies performed in Case No. IPC-
E-18-15; considered comments from intervenors in Case Nos. IPC-E-18-16, IPC-E-20-
26, and IPC-E-20-30; and to the extent applicable, considered components of the
Commission-approved scope in Order No. 34753121or Rocky Mountain Power.
15. Regarding billing structure, the Company proposes to evaluate the following
measurement intervals: (1) monthly, (2) hourly, and (3) separate channel, which is
sometimes referred to as "instantaneous." Under each of the three measurement
intervals, the Company would evaluate the class revenue requirement and consider
revenue collection for existing customergenerators under each proposed measurement
interval. Additionally, the Company would conduct a bill impact analysis to compare how
each measurement interval may impact existing and future customers with on-site
generation.
16. The Company proposes to include several value components of the Export
Credit Rate ("ECR") such as an avoided cost of energy and study the firm versus non-
firm nature of exported energy from customer{enerators. Additionally, ldaho Power
proposes to evaluate avoided generation capacity, avoided transmission and distribution
capacity, avoided line losses, and integration costs as part of the value components of
the ECR study. The Company also recommends studying how the expenditures
associated with the ECR should be recovered.
17. ln addition to billing structure and the ECR applicable to customers with on-
site generation, ldaho Power also proposes to include a review of the project eligibility
cap in coordination with program fundamentals, including rate design and the pricing for
exports. The Company has also included various implementation issues such as credit
expiration and the frequency of updating the ECR.

Serube & lmplemenf a Net Billing Program to Compensate Customer-Generators for Exported
Generation, Case No. PAC-E-19-08, Order No. 34753 (August 26,2020).
APPLICATION . 7
18. lt is the Company's desire that Staff, other intervenors, and the public
provide feedback to develop a record for the Commission to approve the completion of
scope for the "study design" phase.
III. PROPOSED STUDY DESIGN SCHEDULE
19. ln evaluating the "two-phase" approach that the Commission has laid out
for the study, the direct testimony of Company witness Connie Aschenbrenner proposes
a broader schedule to provide transparency to parties and the public as it relates to the
"study design" and "study review" phases, and to the eventua! implementation as
informed by a Commission-approved study.
20. The Company believes the following timeframe forthe "study design" phase
will provide the public, stakeholders, and the Commission time to adequately consider
these issues:
o a notice of public workshops to be held in August or early September 2021
. party comments to be filed in early October 2021
r Company reply comments due late October or early November 2021.
21. This proposed procedural schedule would position the Commission to issue
an order establishing the scope of the study before the end of 2021. Because the
Company plans to use the most recent data available to complete its study (and was
directed to do so in Order No. 34046), receiving an order establishing the scope by the
end of 2021 wtll allow the Company to use 2021 data to complete the study in the first
half of 2022. The Company could then initiate the "study review" phase by June 2022.
22. Absent the Commission establishing a different process, the Company
anticipates making a request to implement any potential changes to the net metering rate
design, compensation structure, or ECR after the Commission acknowledges a study.
APPLICATION - 8
IV. STAKEHOLER & CUSTOMER NOTIFICATION
23. ldaho Power will notiff its customers of this application to initiate the study
with a bill insert that will be sent to all customers in their next billing cycle. lncluded as
Attachment 2, this bill insert will be sent to existing customer-generators, regardless of
legacy treatment, and all other customers that might choose to pursue on-site generation
in the future.
24. The bill insert will provide notice to all customers of the Company's
application to initiate the study. Additionally, the bill insert addresses the following: (1) a
brief summary ol on-site generation; (2) why Idaho Power is making the filing to initiate
the study, (3) the key tenants of the study as directed by the Commission, (4) an estimated
timeline to complete both the study design and study review phases, and (5) how
customers can participate and provide feedback in the study design and study review
process.
25. ldaho Power will notiff the on-site generation system installer community
through an email to the distribution list for its periodic publication, the Customer
Generation Newsletter. Attachment 3 to the Application includes a copy of the notification
that will be sent to installers following the filing.
26. The Company has, concurrent with this filing, updated its website to notiff
potential customers of the proposal; the Company will maintain a list of Frequently Asked
Questions ("FAQs") that will remain accessible to customers, as well as installers. ldaho
Power has also served its Application and testimony on the parties of record in Case Nos.
IPC-E-1 8-1 5 and IPC-E-20-26.

Process for On-Site Generation Study
ldaho Power has initiated the process for a comprehensive
study of the costs and benefits of on-site generation.
This request is outlined in a recent filing with the ldaho
Public Utilities Commission (IPUC). lt kicks off a multi-
phase process whereby ldaho Power will work with the
commission, the public and other stakeholders to (1)
review the scope for a study, (2)complete and review
the study and (3) implement potential changes to ldaho
Power's on-site generation offerings.
What is on-site generation?
On-site generation is a service offering available to
ldaho Power customers who install electricity generating
equipment - most commonly solar panels - at their
home or business to meet some of their energy needs
while remaining connected to ldaho Power's grid. This
offering, also known as customer generation or net
metering, is available to the following customers:
. ldaho residential (Schedule 6)
o ldaho small general service (Schedule 8)
e ldaho and Oregon commercial, industrial, and irrigation
as well as Oregon residential and small general service
(Schedule 84)
