Monsanto Data Request 4.4
Reference Testimony of Mr. John Cupparo. What is the expected megawatt line
rating or capacity of the 345 kV Populus to Term facility before and afer
completion of the gateway West and Gateway South segments?
Response to Monsanto Data Request 4.4
The incremental capacity is expected to be 700 MW in the southbound direction
and 350 MW in the northbound direction prior to completion of Gateway South in
2018-2020. Once Gateway South is completed the capacity in both directions is
expected to increase to 1400 MW. Supportng documentation for the above can
be found at the followig link.

Wht fuction would the Gateway Central serve if.either or both of the South and
West segments are not completed?
Response to Monsanto Data Request 4.5
If Gateway South and/or Gateway West were not completed, Gateway Central will
continue to provide signficant benefits to the Company's customers. Please refer to
pages Di-3 and Di4 in the diect testimony of Darell T. Gerrard below.
. Increase the overall tranmission capacity in the existing trsmission corrdor
between southeast Idaho and northern Utah where the existing system ha
limited capacity and demonstrated operational limitations.
. Meet the imediate need to: (1) Improve system reliabilty in the area and
maintan compliance with national electrcal system reliabilty stadads by
instaling new tranmission capacity to ensure the system can sustan
transmission outaes north of Terminal Substation without curiling loads,
generation or impactig PacifiCorp's East Control Area and neighboring
tranmission balancing authonty areas; and (2) Improve the Company's abilty to
perform maintenance on trmission facilties between Populus and Termnal
by having alternative transmission path that allow facilties to be taen off-line
and maitaed.
. Meet the trsmission capacity and reliabilty requirements to deliver resources
to loads.
. Provide PacifiCorp with greater flexibilty when considenng futue planed
resources to meet customers' growig demands for energy while meeting curent
and futue energy requirements tht may be mandated by state and federal
regulation.
. Faciltate the integrtion of potential new energy resources in Wyomig, Uta,
Idaho and Oregon, and help support economic development in those states.
Furer, Gateway Centrl will reduce the impacts to cusomers durng system
distbances. Pleas refer to pages Di-9, Di-lO, Di-l 1 in the diect testimony of

What is the curent expected on-line date for ful completion of Gateway Central?
Please consider ths a continuig request as any more recent updates arse.
Response to Monsanto Data Request 4.8
Gateway Centra consists of the Populus to Termal transmission segment and
the Mona to Oquirrh transmission segment.
. Populus to Termnal- The first section of the Populus to Terminal segment,
Ben Lomond to Termna, was energized in March 2010. The remainig
section, Populus to Ben Lomond, is anticipated to be energized in November
2010.
. Mona to Oquirrh - Comprised of thee sections that in tota extend
approximately 142 miles from the Mona substation to the proposed Limber
substation. The thee sections include a 67mie 500 kV single-circuit from
Mona to Limber and a 31mile 345 kV double-circuit from Limber to Oquih
estimated to be in-service 2013-2014. The segment also includes a 44 mile
double-circuit 345 kV line from Limber to Termnal planed for 2019 based
upon curent load forecasts. There is potential to constrct Limber to
Termal earlier, if needed to satisfy load growt. A portion of the Limber
Substation is expected to be completed in the 2014 time fre.

Monsanto Data Request 4.9
Please reconcile and provide detaled explantion for the estimted investment
cost of $78 millon for the Populus to Termnal transmission line (ORDER NO.
29998 page 6 Commitment 34 and the requested $801.5 millon contained in
Gerrard Exhibit 34.
Response to Monsanto Data Request 4.9
Durg the MEHC acquisition a tranaction commtment (#34) was made to
execute curently existing plans at that time by increasing the Path C capacity by
300 MW from southeast Idaho to nortern Uta. The objectives of the transaction
commtment dated March 14,2006 were to:
. Enhce the reliabilty of the only high use commercial path between Idaho
and Uta;
. Provide for increased transfer capabilty between the east and west control
areas;
. Faciltate the delivery of futue power from wid projects in Wyoming and
Idao; and
. Provide PacifiCorp with greater flexibilty and the opportty to consider
additional options regarding planed generation capacity additions.
The existing plan scope consisted of two options with a conceptu estimate of
$78M.
. Option I - A combination of new constrction/rebuild the existig 138 kV
tranmission lines from the Treasureton Substation in Idao to the Syracuse
Substation in Uta (a distace of approximately 90 miles).
. Option 2 - Constrct a new single circuit 345 kV line from a proposed futue
Populus Substation to the Ben Lomond Substation in Uta, a distace of
approximately 80 miles.
Subsequent to the Traaction Commtment business conditions drove a
signfication change in tranmission system requiements detaled below. The
Traaction Commitment was fufilled via incorporation into the fin scope of
the Populus to Termin project.
In ealy 2007, PacifiCorp Transmission intiated its anua load and resource
study which forecas network cusomer load with resources for the next ten
years. Compliance with the Opn Access Tramission Tarff requies PacifiCorp
Transsion to respond to network customer's load and resource requiements
with the tig of trmission investents necessar to deliver new network
resoures and to reliably serve load. The results of the study fuer confed
the nee for additiona long term trssion capacity and increased investment
and upgres in Pat C well beyond 300 MW.

Monsanto Data Request 4.9
Since March 2006 and the plan for a 300MW increase a Path C,several
operational events in the Wasatch Front demonstrated Path C is now subject to
signficant reliabilty limtations resulting from double line outae contigencies.
In addition, operationa events between Ben Lomond and Term Substations
occured that demonstrated a clear need to improve capacity and reliabilty in the
par of the system south of Path C. Please refer to pages Di-9, Di-lO, Di-l1 of the
direct testimony of Darell T. Gerrd.
As a result, a new high capacity 345 kV transmission line was recommended
between a new substation in southeast Idaho (Populus) and the existig Termnal
Substation in Salt Lae City. A double circuit 345 kV tranmission line provides
an estimated 1400 MW plang capacity increase when combined with other
segments of the Energy Gateway project. This new line positions PacifiCorp to
serve long-term load growt needs, improve overall system reliabilty.
In 2007, the segment between Populus and Terminal became an integr par of
the Energy Gateway program by providing a critical lin that connects Energy
Gateway West and Energy Gateway South. It provides a vita link between the
Gateway West and Gateway South segments tht will support designed capacity
ratings based on Western Electrcity Coorditing Council plang criteria. The
investment in ths project as requested is $801.5 milion.
