1.0 DESCRIPTIONOF THE PROJECT
("Interconnection Customer")proposed interconnecting 250 MW of new generation to
PacifiCorp's ("Transmission Provider")proposed Aeolus substation at 230 kV located in Carbon
County,Wyoming.The project ("Project")will consist of 125 GE 2.0-116 turbines for a total
output of 250 MW.The requested commercial operation date is November 1,2018.
Interconnection Customer will NOT operate this generator as a Qualified Facility as defined by
the Public Utility Regulatory Policies Act of 1978 (PURPA).
The Transmission Provider has assigned the Project "Q0706."
2.0 STUDYSCOPE AND OBJECTIVES
The objective of the Facilities Study is to:
Complete a facilities analysis,which shall specify and estimate the cost of equipment,
engineering,procurement,and construction required to address issues as outlined in the
system impact study,and
Provide a scope of work and an estimated cost and schedule for completing the scope of
work.
3.0 TYPE OF INTERCONNECTIONSERVICE
The Interconnection Customer has selected Energy Resource (ER)Interconnection Service.
4.0 STUDY ASSUMPTIONS
All active higher priority transmission service and/or generator interconnection requests will
be considered in this study and are listed in Appendix 1.If any of these requests are withdrawn,
the Transmission Provider reserves the right to restudy this request,as the results and
conclusions contained within this study could significantly change.
For study purposes there are two separatequeues:
o Transmission Service Queue:To the extent practical,all network upgrades that
are required to accommodate active transmission service requests will be modeled
in this study.
o Generation Interconnection Queue:Interconnection Facilities associated with
higher queue interconnection requests will be modeled in this study.
The Interconnection Customer's request for energy or network resource interconnection
service in and of itself does not convey transmission service.Only a Network Customer may
make a request to designate a generating resource as a Network Resource.Because the queue
of higher priority transmission service requests may be different when a Network Customer
requests network resource designation for this Generating Facility,the availablecapacity or
transmission modifications,if any,necessary to provide network resource interconnection

service may be significantly different.Therefore,the Interconnection Customer should regard
the results of this study as informationalrather than final.
This study assumes the Project will be integrated into Transmission Provider's system at the
proposed Aeolus 230 kV substation.
The Interconnection Customer will construct and own any facilities required between the Point
of Interconnection and the Project.
Generator tripping may be required for certain outages.
All facilities will meet or exceed the minimum Western Electricity Coordinating Council
("WECC"),North American Electric Reliability Corporation ("NERC"),and Transmission
Provider performance and design standards.
The most current transmission facility ratings were used for the analysis.
All existing and proposed Remedial Action Schemes (RAS)are assumed to be in service for
this study.
The Energy Gateway West (2024)and Energy Gateway South (2024)projects are assumed to
be in service;the Dave Johnston to Amasa (future)to Heward (future)to Aeolus (future)230
kV line is assumed to be rebuilt as part of the Gateway projects.Note that these dates are
inconsistent with the Q0706 Project's planned in-service date.A RAS that will drop up to 600
MW of generation for the followingoutages is assumed to be in-service:
O o Aeolus -Anticline 500 kV line
o Anticline -Populus 500 kV line
o Aeolus -Clover 500 kV line
o Clover 500/345 kV auto transformer
All system improvements associated with the prior queued projects are assumed to be in
service before Q0706.
Based on the Federal Energy Regulatory Commission's proposed revisions to the Pro Forma
Large Generator Interconnection Agreement (Docket No RMl6-1-000),the followingpower
factor requirement was assumed for the Project:
o "9.6.1 Power Factor Design Criteria.Interconnection Customer shall design the Large
Generating Facility to maintain a composite power delivery at continuous rated power
output at the POI at a power factor within the range of 0.95 leading to 0.95 lagging,unless
Transmission Provider has established different requirements that apply to all generators
in the Control Area on a comparable basis.Non-synchronous generators shall only be
required to maintain the above power factor when their output is above 10 percent of the
Generating Facility Capacity."
The 2.0 MW GE wind turbines for Q0706 were assumed to have a +/-0.9 power factor at
turbine terminals.
Transmission Provider reserves the right to restudy the Project if any of the above mentioned
assumptions are changed or if any of the required mitigations are not in service at the time of
interconnection.
This report is based on information available at the time of the study.It is the Interconnection
Customer's responsibility to check the Transmission Provider's web site regularly for
Transmission System updates at http://www.pacificorp.com/tran.html

5.0 PROPOSED POINT OF INTERCONNECTION
The Interconnection Customer's proposed Generating Facility is to be interconnected through a
new 230 kV bay at the proposed Aeolus substation.The Interconnection Customer will construct
a seven-to eight-mile 230 kV transmission line into the Aeolus substation from their 230 kV
collector substation.Based on the data provided by the Interconnection Customer,the Project
consists of two 230 -34.5 kV transformers with the rating of 84/112/140 MVA each.Each one of
the 230 -34.5 kV transformers is connected to two separate 34.5 collector systems.The first
collector system has sixty-two (62)2.0 MW GE turbines connected to it totaling 124 MW and the
second collector system has sixty-three (63)2.0 MW GE turbines connected to it totaling 126
MW.The total maximum output of the Project shall not exceed 250 MW.
Figure 1 below is a one-line diagram that illustrates the interconnection of the proposed Generating
Facility to the Transmission Provider's system.

6.0 SCOPE OF WORK
6.1 Generating Facility Modifications
The following outlines the design,procurement,construction,installation,and ownership of
equipment at the Interconnection Customer's Generation Facility.
6.1.1 INTERCONNECTIONCUSTOMERTO BE RESPONSIBLE FOR
Design,procure,install,and own all equipment required for the Large Generating
Facility.
Obtain all necessary permits,lands,rights of way and easements required for the
construction and continued maintenance of the facilities required for the Q0706 Project.
All easements and permits shall be recorded in the name of the Transmission Provider
and shall be on forms acceptable to the Transmission Provider.All easements and rights
of way will be obtained for durations acceptable to the Transmission Provider;this
includes all permits/easements for ingress and egress prior to the start of construction.
o Provide a separate fenced area along the perimeter of the Interconnection
Customer's Generating Facility in which the Transmission Provider can install a
control house for any protection and communication equipment.This area will
O share a fence and ground grid with the Generating Facility and have separateaccess.
AC station service for the control house will be supplied by the Interconnection
Customer.
Provide a CDEGS grounding analysis.
Design and install conduits,per Transmission Provider's standards,to the demarcation
point.
The collector substation batteries will be sized to carry the communication equipment
with DC to DC converters.
Demonstrate the reactive capability of the facility and the voltage control system prior
to commercial operation.Conditions of operations include:
o Operate in voltage control mode with the ability to deliver power output to the POI
within the range of +/-0.95 power factor.(Please see Standard Large Generator
Interconnection Agreement,article 9.6.1 and 9.6.2 in OATT.)Any additional
reactive compensation must be designed such that the discrete switching of the
reactive device,if required,does not cause step voltage changes greater than ±3%
at any load serving bus on the Transmission Provider's system.
o As required by NERC standard VAR-001-la,the Transmission Provider will
provide a voltage schedule for the POI.Generating Facilities should be operated so
as to maintain the voltage at the POI,or other designated point as deemed
appropriate by Transmission Provider,between 1.00 per unit to 1.04 per unit.The
Transmission Provider may also specify a voltage and/or reactive power bandwidth
as needed to coordinate with upstream voltage control devices such as on-load tap

changers.At the Transmission Provider's discretion,these values might be adjusted
depending on operating conditions.
o At low output levels,the Project needs to ensure that it maintains the power factor
within ±0.95 at the POI and minimize the reactive power flow towards the
transmission system to prevent high voltages.
o Generating Facilities capable of operating with a voltage droop are required to do
so.Voltage droop control enables proportionate reactive power sharing among
Generating Facilities.Studies will be required to coordinate voltage droop settings
if there are other facilities in the area.It will be the Interconnection Customer's
responsibility to ensure that a voltage coordination study is performed,in
coordination with Transmission Provider,and implemented with appropriate
coordination settings prior to unit testing.
o For areas with multiple Generating Facilities,additional studies may be required to
determine whether or not critical interactions,including but not limited to control
systems,exist.These studies,to be coordinated with Transmission Provider,will
be the responsibility of the Interconnection Customer.If the need for a master
controller is identified,the cost and all related installationrequirements will be the
O responsibility of the Interconnection Customer.
Design,procure,install,and own Phasor Measurement Units (PMUs).
Provide a standard model from the WECC Approved Dynamic Model Library prior to
interconnection,since the Transmission Provider cannot submit a user written model
to WECC for inclusion in base cases.The list of approved generator models is
continually updated and is available on the http://www.WECC.biz website.
All generators must meet the Federal Energy Regulatory Committee (FERC)and
WECC low voltage ride-through requirements as specified in the interconnection
agreement.
Prior to construction,arrange construction power with the Transmission Provider.The
Project is within the Transmission Provider's service territory and both station service
and temporary construction power metering shall conform to the Six State Electric
Service Requirements manual.
Prior to back feed,arrange distribution voltage retail meter service for electricity
consumed by the Project and arrange back up station service for power that will be
drawn from the transmission or distribution line when the Project is not generating.
Interconnection Customer must call the PCCC Solution Center 1-800-640-2212 to
arrange this service.Approval for back feed is contingent upon obtaining station
service.

Interconnection Customer will need to provide the output from two sets of current
transformers to be fed into the bus differential relays with a maximum current
transformer ratio matching the maximum CT ratio of the breakers at Aeolus
substation.If a fault is detected,both the 230 kV breakers in Aeolus substation and
the 230 kV breaker in the Interconnection Customer's tie line substation will be
tripped.
o A relay at Aeolus substation will monitor the voltage magnitude and frequency.If
the magnitude or frequency of the voltage is outside of normal range of operation
a signal will be sent over the communication system to the collector substation.At
the collector substation this signal is to trip open all of the 34.5 kV feeder breakers
to disconnect the wind turbine generators.By tripping the 34.5 kV breakers instead
of the 230 kV breakers the station service to the Generating Facility is maintained
to facilitate the restoration of the generation.This relay will also have phase and
ground directionalovercurrent elements set to operate for faults in the line between
Shirley Basin substation and the Interconnection Customer's collector substation
and serve as a back-up to the main protection installed by the Interconnection
