liP A Data Request 4.
On July 11 , 2007 there was a report issued by PacifiCorp assessing demand side
resources. With respect to that report, in Volume I, near the bottom of page ES-
10 there is a reference to the fact that participant incentives are currently capped
at approximately 50% of "incremental measure costs" of Class 2 DSM resources.
Please explain what "incremental measure costs" are and give an example.
If "incremental measure costs" are not an appropriate term, please explain
what the 50% is related to.
What is the basis for the 50% cap?
Is there a related cap applied to Class 1 or 3 DSM resources? Please
explain the relationship between such a cap for Class 1 and 3 resources
compared to Class 2.
Response to liP A Data Request 4.
Incremental measure costs" refers to investments required to be made by
customers in order to participate in Class 2 DSM programs. Customer
incentives for Class 2 DSM programs are typically measured as a
percentage of out of pocket customer costs up to a cap. The Idaho
Irrigation Energy Savers program uses the 50% cap explicitly in the
incentive calculation (see Idaho Schedule 155.4).
The term is appropriate as used in the report.
Energy efficiency programs are designed to provide incentives for the
purchase of more energy efficient equipment not to pay customers for
replacing equipment. The equipment also needs to deliver energy savings
over time. For these reasons, most programs pay a percentage (less than
100%) of the incremental costs so the customer is invested in equipment
upgrades and efficient operation over time. The 50% cap is explicitly
incorporated into several incentive formulas in the company s energy
efficiency programs and is the basis for setting the incentive levels in other
programs. Other utilities and program administrators use a similar
percentage cost cap in many of their program designs. For these reasons
50% was used in this study in the assessment of the expected achievable
potential for Class 2 resources.
In the case of Class 1 and 3 resources, customers typically are not required
to make investments in equipment to participate in demand-side resource
programs. As a result, customer incentives are tied to metrics such as
kilowatts available for control rather than as a percentage of out of pocket
customer costs up to a cap, as in the case for Class 2 programs. In
designing incentive structures for Class 1 and Class 3 programs, programs
P AC- E-07 -05/Rocky Mountain Power
August 31 , 2007
lIP A 4th Set Data Request 4.2
typically are required to pay an incentive each time (per month or per
year) the capacity resource is made available for control or controlled.
Unlike Class 1 and 3 resources, energy efficiency programs typically pay
an incentive once and the energy efficiency resources are realized over
time. These are some of the reasons that incentive design considerations
(including the use of percent of customer costs) differ between these
resource types.

noted in individual state files), single year data for others and was lacking
available California data at the time the profiles were created. In all the cases
except California, the most recent year s data for each state and rate schedule
were used in the development of hourly system load profiles. In the case of
California, Oregon s load profiles by customer class were used. Single year data
was used (as opposed to multiple year averages) in order to retain the peak

liP A Data Request 4.
On July 11 , 2007 there was a report issued by PacifiCorp assessing demand side
resources. With respect to that report, in Volume I page 17 there is a statement
that Rocky Mountain Power s avoided cost of capacity is $98.
a. Is this value of$98 based on a "kW-year" basis? Please explain what
these units represent.b. 'Is this capacity value only related to the peak hour of the year, the highest
40 hours of the year, the peak hour of each month, etc.
Please provide all calculations and studies used to develop this value of$98.
Response to liP A Data Request 4.
In section 6, Estimating Economic Potential , the reference to the
company s estimated avoided cost of capacity of $98 for Rocky Mountain
Power was based on dollars per kilowatt per year. It represents an estimate
of the value used to set the upper boundary for screening capacity
resources for their cost-effectiveness within the study.
The capacity represents the company s coincident peak loads. Coincident
peak loads are derived by forecasting and then aligning the hourly
maximum loads each month across the entire system. Coincident peak is
the highest load hour each month across the entire system.
The $98 value used to screen load management demand-side resources in
Rocky Mountain Power s service territory was derived from proxy
modeling of load management resources within the company s 2007
Integrated Resource Plan. For the development of that plan, the company
commissioned a smaller potential assessment and costing of five load
management program concepts into supply curve formats for comparative
modeling against supply-side resource alternatives. The five program
concepts developed and modeled were: (1) a fully dispatchable winter
resource, (2) a fully dispatchable summer resource, (3) a fully dispatchable
large commercial and industrial resource, (4) a scheduled firm irrigation
resource, and (5) a thermal energy storage resource. In Rocky Mountain
Power s service territory, the model selected all available fully
dispatchable summer resources (at $58/kw/yr), all available fully
dispatchable large commercial and industrial resources (at $82/kw/yr) and
all scheduled firm irrigation resources (at $27/kw/yr). Based on the
modeling results the company determined the value of the resources to be
greater than $82/kw/yr (based on the model selecting the fully
dispatchable large commercial and industrial resources) but less than
$119/kw/yr (the cost for the thermal energy storage resources that weren

selected). The $98/kw/yr was selected as the estimated value to Rocky
Mountain Power, ignoring unique resource characteristics (such as
dispatchability, hours, etc.), after which load management resources
become uneconomic in relation to other resource alternatives. No
additional analysis was done in arriving at the $98/kw/yr figure. The
company s 2007 Integrated Resource Plan is available in an electronic
format at http://www.pacificorp.comlNavigation/Navigation23807.html.
The proxy supply curve study conducted for the plan is provided in

Response to liP A Data Request 4.
a. The $/kw/yr value was derived using the achievable resource potential
(providing program size) and the standard program cost assumptions
(referenced below) to derive a total program cost. This cost was then
levelized over a 20-year planning period to identify the resource value. As
such, a breakdown of the cost components beyond that provided in Volume II

b. The costs do not assume a particular program however they do draw from
estimated costs of several programs such as the company s Idaho Schedule 72
and 72A as well as Idaho Power s program. The $47 is meant to represent a
proxy for program costs, actual implementation costs may vary with factors
such as size of program, average pump size, and pump configurations
impacting those costs.

participants, 50% of participating loads will elect a scheduled firm control option
(similar to Idaho s Schedule 72) and 50% will elect a dispatchable control option
(similar to Idaho s Schedule 72A). Under these assumptions during any given
day, 50% of the scheduled firm participant loads would be curtailed and, upon
dispatch, 100% of the dispatchable loads would be available; thus arriving at the
assumption that 75% of the loads participating are curtailed during an event.

Response to liP A Data Request 4.
a. As noted in Volume II Page B-13 of the study s assumptions, they are similar
however represent a composite of programs (see references to Idaho Power
and PacifiCorp program similarities and differences in the Sources or
Assumption column). They are slightly higher in some areas, such as the
technology costs and communications portion of ongoing maintenance and
communications, than those typically realized with Schedule 72 in Idaho.
These costs are more representative of anticipated Schedule 72A in Idaho or
technology that as employed provides greater control flexibility and network
reliability. The remaining assumptions and costs are similar to the company
Schedule 72 program and Idaho Power s irrigation load management program
except where noted in the Sources and Assumptions column.
b. As noted in the company s response to part "" the study s costs and
assumptions are a composite of program costs and assumptions however are
more closely in alignment, in regards to the technology and communication
costs, with the equipment employed under the company s Schedule 72A in
Idaho. They assume that similar control equipment as that deployed in the
company s Schedule 72A dispatchable pilot program would be utilized by
both control options (Schedule 72 and Schedule 72A) in the future to improve
control functionality and network reliability.

a. The incremental cost of meters is listed as $100. What is the maximum load a
meter of this cost is designed to carry?
b. Will this meter handle 3 phase power?c. Why does "this analysis assume revenue neutrality for the utility" when
some customers will accrue bill savings?d. How should the rates for Schedule 36 be designed in order to be revenue
neutral for the Company and show a differential of 10 cents or more per kWh?
Response to liP A Data Request 4.
The $100 incremental cost was based on the average cost differential
between a standard residential meter and a residential time of use meter
with an assumed amperage rating of200.
The price difference between a single and three phase 200 amperage rated
meter is immaterial and the study made no assumption as to a single or
three phase meter when calculating incremental costs.
This analysis assumes revenue neutrality for the utility because, during the
rate making process of each schedule, there is a targeted amount of
revenue that proposed rates are to collect; and while it is true some
customers may accrue bill savings from these proposed rates, other
customers may receive bill increases based on individual usage.
