LIP A Data Request 99
LIP A Data Request 99
The response to Monsanto Request 5.5 was designed to explai how the
normalized revenues were developed to each group of customers. Under a
colum entitled "Booked" revenue, the tota Irgation amount is $37,541,443.
Please answer the following:
a. Is the $37,541,443 actu 2009 Irgation revenue? Ifnot, what is it?
b. Wht is the basis for the "Normalization" adjustents that totaed $233,778?
c. Please provide all calculations tht produced the $233,778 figue, includig the
rates, biling determts, and eqlltions and data useg to deve10pthe uonni?ed
biling determinants.
d. Please explai the basis and provide the calculation for the "BP A" adjustments.
Response to lIP A Data Request 99
a. Yes, the $37,541,443 was the actu2009 Irgation revenue includig BPA
Balancing Account and Line Extension revenue.
b. The "Normalization" adjustments that totaed $233,778 were out of period
adjustments.
c. The out of period adjustments remove revenues biled and report in 2009
that were based on mete reading dates tht were not in 2009. Ths anysis
was prepared based on a maie data query that analyzed eah irgation
customer's biling data history in the Company's customer biling database.
The tota out of period adjusents by rate code were presented in the
atthment to the Company's response to Monsanto Data Request 5.5.
d. The BP A Balancing Account adjustents were the tota balance at the end of
2009 representig the difference between what BPA paid to the Compay and

LIP A Data Request 100
IIPA Data Request 100
The responses to lIP A Requests 56 and 72 contan a disclaier tht: "Note: The
MV90 Load Research System usd to calculate class averages and class load
does not save the individua customer data used to generate the class averages and
class loads..." Please answer the followig:
a. Historically, the Company has "cleaned up" its raw load research data in order to
remove data that may be incomplete or of suspicious quaity. Was ths "cleanup"
done prior to the data being entered into the MV90 Load Researh System and
then used to calculate class averages and class loads? If it wa "cleaned up",
pleae provide the original data and the "cleaned up" data tht served as input to
the MV90 Load Research System.
b. If the Compay was able to supply individua hourly load research data by sample
customer in the response to lIP A Request 56, why doesn't the Company know
what data was supplied to the MV90 Load Research System prior to makng its
calculations?
c. Wht evidence or basis does the Company have for assumng tht the MV90 Load
Research System data (and thus results) is more accurte than what can be derived
from the hourly load researh data tht was supplied in response to IIPA Request
56?
Response to IIA Data Request 100
a. The individua sample customer data provided in LIP A Request 56 is the data tht
served as input to the MV90 Load Researh System to caculate class averages
and class load. Manua clean up fuctions such as removig data tht may be
incomplete or of suspicious quaity wa performed prior to input into the MV90
Load Researh System ard is reflected in the data provided. The MV90 Load
Research System also provides some automated clean up fuctons. Curntly the
clean up fuctons active in the MV90 Load Resech Systm are to exclude
"lapse in data" and accounts with "1000!c missin data". The MV90 Load
Reseach System does not save ths cleaned up data on an individua customer
basis. Because the system does not save individua customer data it is extremely
diffcult, if not impossible, to duplicate the Load Research system da in an
Excel spreadsheet.
b. The individua cusomer data supplied in lI A Request 56 is the data supplied to
the MV90 Load Reseh Systm. Bece theMV90 Load Reseach System
does not save individua cusomer data the automated clean up fuctons
performed by the syste ar not known on an individua cusomer basis.

c. The MV90 Load Research System reviews, validates and processes data at a more
granular level than can be achieved by a simple extract of the customer load data
into spreadsheet compatible softare. As such, estites derived from ths
process are deemed to be more accurte th what can be derived from the hourly
load research data that was supplied in response to lIP A Request 56, in the sense
tht it has been fuer cleaned up by excluding data for "lapse in data" and
"100% missing".

lIP A Data Request 101
The responses to lIP A 38 and lI A 65 indicate that thee years of data (2006,
2007, and 2008) were used to establish distrbution factors such as NCP and
Schedule peak data. Please anwer the followig:
a. Why wasn't 2009 data used?
b. Wht was the source that was used to derive the NCP data and the Schedule peak
data the saple data that was provided in response to lIP A Request 56 or did it
come from the MV90 Load Reseach System? If the NCP and Schedule peak
values were not derived from either of the above, please provide a copy of the
Irrgation sample data sets tht were used.
Response to IIPA Data Request 101
a. NCP data was estimated based on a thee year average of the ratio of
NCP/Schedule pea. 2009 data was used in the sense tht the thee yea average
ratio was applied to 2009 schedule peak data to estimate NCPfor 2010.
b. The source data used to estiate data for 20 I 0 came from the MV90 Load
Reseach System.

Regarding the response to lIP A Request 67 regarding the cost of the Cool Keeper
program in Uta, please anwer the followig:
a. Wht was the "levelized cost of Rocky Mounta Power's Cool Keeper program
that was procured and implemented in 2003 under a I 0 year pay- for-performance
program strctue"? Please provide a copy of any report tht was produced in
2003 that support ths levelized costs and explais the assumptions involved.
b. On a simlar basis as the above justfication for the Uta Cool Keeper progr
requested in "a" above, what was the levelized cost of the Idao Irgation
curlment program? Pleae provide a copy of any report tht was produced
when the designted day progr was implemented tht support ths levelized
costs and explai the assumptions involved. Please provide a copy orany report
tht was produced when the Company Option progra was implemented that
supports ths levelized cost and explains the assumptions involved. '
c. With respect to the Cool Keeper program as addresse by the Quatec Report and
the response to lIP A Request 67, what was the cost associated with "new
resources" and what was the cost of "operatig" the system?
d. With respect to the Idaho Irgation Curlment program( s) as addressed by the
Qutec Reprt and the respons to lIP A Request 67, what was the cost
associated with "new resoures" and what was the cost of "operatig" the system?
Response to IIA Data Request 102
a. The averge or levelized cost of the 10 year pay-for-performce based
progr under the Utiity Cost Test (inclusive of customer incentives) when fied
in 2003 was calculated to be $60.02 pe kilowatt. Please refer to Atthment liP A
102 -1 for a copy of the origi program fiing, see the seon titled "Air
Conditionig Load Control Servces Program: Economic Analysis in Support of
Uta Tarff Filing" prepar by Quate LLC, dated May 8, 2003.
b. The Idao irgaton curent progr is a yea-by-year program offerig
with loa curlments subject to day-ahea pacipant notification. The leveliz
cost to delivery ths program ca be calculated from da provided in the anua
Schedule 72 and 72A Idao Irgaton Load Control Progr Credit Rider
Intiative Fin Report filed with the Idao Public Utilities Commssion each
November. Please refer to Atthment lI A 102 -2. The values var from year to
yea bas on pacipatin progr load and actu costs (includig
parcipaon credits) and have raged from a low of approximatly $22 kW in
2007 to a high of $45 kW in 2009 (as caculate by the tota progr costs for a
given year divided by the mea of the net parcipating load (net of opt-outs) in
tht year. Unlike Uta's COL Ker ai conditioner load manement program,

the loads used in calculating the levelized costs of the Idao irgation curaient
progr are derived from parcipating loads, not meaured load curiled or

c. The Qutec Report assumed $93/kW per year for new residential air
conditionig load control resources. For inormation regardig the basis for the
