Montana via a 240/230 kV transmission line.
Within Alberta, the construction of a new substation approximately 6 km north of
Lethbridge including three 240 kV breakers in a ring configuration and approximately 1
km of double circuit 240 kV line to accommodate the MATL interconnection. MATL’s
merchant line will be Alberta’s first direct transmission interconnection with the United
States.
The proposed transmission line is a 230 kV three-phase AC line running from north of
Lethbridge, Alberta, to Great Falls, Montana. In Alberta, the line will be connected to
the existing 240 kV line (923L) through a new substation Picture Butte 120S located 15
km northeast of the existing North Lethbridge 370S substation. In addition to the
substation connection facilities the substation will also contain a 240/230kV phaseshifting transformer to control the amount and direction of power flowing on the line.
From the proposed substation, the transmission line will head east and south before
leaving Alberta and entering Montana. The line will continue southward through
Montana to a new mid point station, Marias Substation, and then on to Great Falls. At
Great Falls, the line will connect to an existing NorthWestern Energy (NWE)

The AESO has identified the need to reinforce the transmission system in the south
Calgary and in the High River Planning area. This reinforcement will alleviate the
existing and anticipated constraints to accommodate the expected load growth and
integrate the proposed generation capacity within the subject area, and facilitate
transmission of generation from southern Alberta to load centers. The FATD project
will consist of two separate sub-projects.
This project proposes to install various 240 kV lines between substations Janet 74S,
SS-25, SS-65, Foothills 237S and Langdon 102S to improve the area system capacity
as well as the construction of a new Substation Foothills 237S. Also included in this
project is the installation of 138 kV lines in the High River planning area.
The new Foothills 237S substation will serve as the termination points for the double
circuit line 1029L/1030L from Peigan 59S. This is where the Southern Alberta
Transmission Reinforcement (SATR) project is tied with FATD project to achieve the
required overall system performance.
The scope of the 240 kV transmission developments included in the AESO’s FATD
East NID is as follows:
• A new 240 kV substation designated Foothills 237S that includes two new 240/138
kV transformers, each with a rating of 400 MVA.
• A new 240 kV double circuit line from Foothills 237S substation to future ENMAX No.
65 substation with a minimum summer rating of 600 MVA for each circuit. The lines will
be designated 1106L and 1107L.
• A new 240 kV double circuit line from Langdon 102S to Janet 74S with a minimum
summer rating of 800 MVA for each circuit. The lines are designated 1064L and
1065L.
• Create a new 240 kV double circuit line from Langdon 102S to East Calgary 5S2
using a combination of lines 936L, 937L, 917L, and 1077L; 917L and 1077L, which
were included in the East Calgary NID are connected to 936L and 937L to create the
new 240 kV path between East Calgary and Langdon substation in FATD East NID. As
per the TFO’s data submission, the summer rating of each circuit is 489 MVA. The
lines are to be designated 936L and 937L.
Summary of Transmission System Developments included in the ‘FATD East’ NID
• Create a 240 kV double circuit line between future ENMAX No. 65 substation to
future ENMAX No. 25 substation, by energizing sections of the existing 850L
transmission line to 240 kV. Transmission line 850L is built to 240 kV standards and is
currently operating at 138 kV. 850L and 1080L share the same towers. As per the
TFO’s data submission, the summer rating of the line is 489 MVA. The line designation
will be changed from 850L to 1109L.
• Terminate line 985L at Janet 74S substation, thus completing the circuit. The new
240 kV transmission line 985L is included in the East Calgary NID and proposed to be
built on the same towers as 1003L. The minimum summer rating of this line is 920
MVA.
• De-energize sections of the 911L line from south of ENMAX No. 65 substation to
Foothills 237S.The existing 911L in the High River planning area will be de-energized
upon completion of theSATR project.
The project has been approved by the Alberta Utilities Commission in October 2013,
ISD forecasted for 1117- FATD-East is Q3 2015.

connection. The Stage 2 development is dependent upon the completion of
transmission lines 1004L/992L from Fidler 312S to Chapel Rock 491S for connection.
Under the current configuration, the wind power plant will consist of Vestas V90 3MW
wind turbines. Both stages are onhold pending regulatory approval of Fidler 312S and
transmission lines 1004L/992L.
The reason for the staged approach is to inject as much as the system can handle
without serious RAS constraints prior to the approval and completion of the Chapel
Rock substation (connection to the 500 kV line). After the Chapel Rock Substation is
built the system in the Pincher Creek area will become unconstrained (mostly) and will
be able to handle the full projected output of the Heritage Windfarm.

West Alberta Tie-Line (WATL) connects from new Sunnybrook substation near
Genesee substation in the Wabamun Area to Langdon substation which is also the
terminal of 1201L 500kV BC-Alberta Tie-line. It will be built as bi-pole line with 1000
MW mono-pole converters using remaining conductor as metallic return. The project
was approved by the Alberta Utilities Commission on December 6, 2012.
The addition of these two HVDC lines will significantly increase the North to South
transfer capability (SOK limit) within Alberta. As the 1201L 500 kV Alberta to BC export
capability is limited by the SOK limit, the addition of these two lines will increase the
Total Transfer Capability of 1201L.
This impact will be quantified by Inter-Tie Rating Studies and HVDC Operations
Studies scheduled to be completed by the end of 2014.
The estimated ISD of WATL is April 2015 and ISD of EATL is December 2014.

Increased transmission capacity is needed in the area northeast of Pincher Creek and
west of the Piikani Nation reserve to provide several wind generating facilities, two of
which are already in service and others which are planned to be in service within the
next two years, access to the transmission system. The existing two wind generating
facilities are frequently required to reduce output during normal operating conditions
due to existing transmission system constraints. The Fidler 312S Collector Substation
Connection Project NID was submitted by the AESO to the AUC on October 26, 2012.
NID and FA approval is expected by August 2013. The planned in-service date is April,
2014.
The Fidler Project includes a two stage development.
Stage 1:
• Develop a new 240/138kV collector substation with one transformer
• Add a new double circuit 240 kV line connecting Fidler 312S to the existing 1071L
transmission line in an in-out configuration
• Rebuild existing portions of 138 kV transmission lines connecting into the Fidler 312S
substation
• Configure 893L between Goose Lake 103S and the tap-off to Oldman River Dam
806S to normal open under normal operating conditions
Stage 2:
• Add a second transformer at Fidler 312S

Peaking Station (“the Project”) as a new point of supply (POS) - Project 1290. The
Project is to be developed in one stage with an in service date (“ISD”) of May 1, 2014.
The plant consists of 4x50MW of gas fired peaking units.
The plant is located in the Peace River area (Area 19) in the vicinity of LSD 29-85-19W5 which is located approximately 13.5 km to the north of the existing Wesley Creek
834S substation. The preferred alternatve is to complete an in and out connection to
7L106 in the Northwest Region of Alberta.
The project is currently in Stage 3 out of 6 of the Connection Process and a Functional
Specification is being drafted by the AESO with Planned In-service date of May 1,
2014

The proposed project has an in service date of July 1, 2015. A total of three 230 MW
cogeneration units are planned with 70 MW of on-site load. Shell intends to build a
customer owned 240/25/18 kV substation and seeks an Industrial System Designation
for the project. All projects loads will be served from Shell's proposed substation. The
transmission connection requested could be a double-circuit 240 kV line from Carmen
Creek to Wesley Creek in the Northwest Region of Alberta (Alternatives currently being
studied).
Project is currently completing studies and is in Stage 2 of the Connection Process
with planned ISD of July 1, 2015

On April 30, 2013 AESO received a System Access Service Request (“SASR”) from
Capital Power L.P. to connect a 1000MW Power Generation Facility, the Capital Power
Energy Centre (“CPEC”) to the AIES.
The CPEC will be a new gas combined cycle facility to be located within the Genesee
Generating Station land. The new facility will consist of two Gas Turbine Generators
(“GTG”) and associated Steam Turbine Generator (“STG”).
CPEC indicated that the Gross Generation Capacity is expected to be up to a
1000MW; which could be developed in stages to meet Alberta’s demand. Therefore,
the study will proceed with the assumption that the gross capacity of the proposed
generating station is 1000MW.
The facility in-service date is currently expected to be December 31, 2017; however,
CPEC indicated that this date is subject to change due to market conditions.

Consisting of a Chief Joe – Monroe 500 kV line, this project is associated with load
service and is on hold until load growth supports construction.
A 345/161-kV transformer at PacifiCorp’s (PAC) Goshen Substation currently serves
the Lower Valley area. Three transmission lines serve load out of Goshen. The
Goshen-Drummond 161-kV line serves mostly Fall River loads and provides back-up
service to Lower Valley. The Goshen- Swan Valley 161-kV line serves most of the
Lower Valley load. The Goshen-Palisades 115-kV line serves the Palisades
Generating Plant and some Lower Valley load.
BPA constructed a second Swan Valley-Teton line in 2000 and upgraded the GoshenDrummond line to 161-kV in 2002. These upgrades increased the reliability of the Fall
River system and helped support load growth in the Jackson Hole area, but did not
increase the transmission capability to the southern part of Lower Valley’s system.
Capacitor banks have been installed at Targhee, Tincup, Teton, and Madison.

This purpose of this project is to increase the transfer capability of the I-5 Corridor in
the vicinity of Southwest Washington and Northwest Oregon. This load service area
includes the cities of Portland, Oregon and Vancouver, Washington, which include high
concentrations of industrial, commercial, and residential load. The generating
resources serving this area are a mix of hydro and thermal plants.
This proposed project includes a new 500 kV transmission line (approximately 70
miles) between Castle Rock, Washington and Troutdale, Oregon. This would require
the construction of a new 500 KV switching station in the vicinity of Castle Rock
Washington and the expansion of BPA's Troutdale Substation near Troutdale, Oregon.
The project is projected to increase capacity by approximately 1100 to 1400 MW on
the South of Allston path.

This purpose of this project is to improve load service reliability to the Puget Sound
area and Northern Intertie. The Puget Sound and Northern Intertie (PSANI) area
transmission system is a winter peaking system that primarily consists of the
interconnected systems of BPA, Puget Sound Energy (PSE), Seattle City Light (SCL),
Snohomish PUD (SPUD), Tacoma Power Utilities (TPU), and British Columbia
Transmission Company (BCTC), which serve Seattle, Tacoma, Olympia, and
surrounding areas.
The Puget Sound Area is a highly congested network due to large concentrations of
load and varying local generation patterns, which are further stressed by transfer levels
between the US and Canada on the Northern Intertie. Winter peak loads are typically
the worst, combined with lower local generation patterns and high exports to Canada.
Through a joint Columbia Grid study effort, several system fixes have been agreed to
by BPA, SCL, and PSE. They include several 115kV and 230kV PSE and SCL line
upgrades, a BPA RAS upgrade and a new BPA 500/230kV transformer. The PSANI

Reinforcements projects are scheduled to be completed in full by fall 2018. The Raver
500/230kV transformer addition is scheduled for completion in fall 2016.
The most limiting outage for the South Puget Sound area is a common corridor N-2
Tacoma- Raver #2 and Raver-Covington #1, which results in loss of two 500/230kV
banks in the area. Other N-2 common corridor outages result in a loss of two
500/230kV banks either at Tacoma, Covington, or Maple Valley substations and cause
severe loading on the remaining transformer banks. Once the Raver 500/230kV
transformer addition is completed, the severity of these N-2 outages will be greatly
reduced, mitigating overloads, and resulting in greater reliability to load service and
operational flexibility for the Southern Puget Sound Area. The project also helps to
reduce the risk of curtailment or redispatch events in the Puget Sound Area for certain
outage conditions.
The plan of service is to install a 1300 MVA transformer at Raver substation. A new
230kV substation will be developed adjacent to the existing 500kV substation. The
high side of the new transformer will terminate at Raver 500 KV. The Tacoma-Raver
#1 and #2 500 KV lines are currently jumpered together and operated as double circuit
500kV for about 10 miles from Raver until it reaches Covington substation. The
corridor for both circuits runs adjacent to Covington 230kV station and in the same
corridor as the Raver-Covington #1 and #2 500 KV circuits. The project will reconfigure
the Tacoma-Raver 500 KV lines by removing jumpers and reterminating the TacomaRaver #2 circuit into Covington 230 KV and Raver 230 KV Substations. The TacomaRaver #2 line will be renamed and operated as the Raver-Covington #3 230 KV line.
The plan of service also requires reconfiguring the Covington 230 KV bus, adding a
new sectionalizing breaker and 2 bus tie breakers.

The purpose of this project is to increase transfer capability across the West of
Cascades North Path and provide increased load service to the Puget Sound area.
This project adds 500 kV series capacitors at Schultz Substation on the Schultz-Raver
500 kV #3 and the Schultz-Raver 500 kV #4 lines.

The Pacific DC Intertie (PDCI) provides a direct current (DC) intertie between The
Dalles Oregon, and Los Angeles, CA. The current PDCI is rated at 3100 MW.
The PDCI Uprate project would increase the capacity by 700 MW from 3100 MW to
3800 MW. This project replaces the convertors at the Celilo HVDC terminal and reconductors a small section of the DC transmission line. To reach the full 3800 MW will
require the southern partner (LA Department of Water and Power) will need to
reinforce the AC system on the southern end, upgrade some DC line sections, and
make minor changes to their terminal equipment.
John Day Substation is a major 500 KV switching station east of The Dalles Oregon. It
serves as the northern terminus of the California-Oregon AC Intertie (COI). It
integrates the generation from the US Corp of Engineers John Day Dam. It the next
major 500 KV substation west of Slatt Substation. In 2007, a 230 KV yard was added
to interconnect Portland General Electric's (PGE) 400 MW Bigelow Canyon wind

In 2010, Bonneville Power Administration (BPA) conducted a Network Open Season
(NOS) to determine projects needed for requests for long-term firm transmission
service. During the NOS process, entities requested the use of BPA's transmission
system to transmit their power.
“
The studies found that there was not enough available transmission capacity to
accommodate all requests for long-term service from BPA's Garrison Substation in
Western Montana to load centers west of the Cascades and to market hubs serving
the entire Northwest power market. Wind generation facilities built and proposed in the
region have greatly increased the amount of planned generation in Montana seeking
load and markets in the Northwest. As a result, BPA is proposing several
reinforcements on BPA's transmission system at Garrison, Hot Springs, Bell,
Dworshak, and Hatwai Substations.
Additionally, reconductoring is being proposed totaling 12 miles on the Dworshak-Taft
No. 1 500-kilovolt (kV) line and a new series compensation substation is being
proposed along the Garrison-Taft No. 1 and No. 2 500-kV lines, both of which would

A new 230/138 kV 300 MVA transformer will be installed in the existing King 138 kV
substation to accommodate approximately 135 – 150 MW of additional wind
generation in the Hagerman area. The King substation will be interconnected to the
230 kV transmission system by looping in-and-out the existing Midpoint-Dram 230 kV
line. Because the wind generation projects, which the King 230/138 kV project is to
accommodate, have been slow in their development, the in-service date has been
deferred to spring 2012. This project has no significant impact on the WECC
transmission system.

plan for meeting our electric service obligation, identified Pacific Northwest generation
resources as one component of the preferred resource portfolio. Requirements of
Idaho Power’s wholesale transmission customers are also increasing. The existing
transmission system connecting Idaho Power to the Pacific Northwest is fully
subscribed during high-demand periods. To meet the need for more transmission
capacity with the associated improvement in system reliability, Idaho Power plans to
build a 500 kV transmission line from southern Idaho to northeast Oregon.
The plan of service is to construct a 300 mile 500 kV transmission line from
Hemingway station in southwestern Idaho to a new station, Grassland or Longhorn
depending on final routing, near the existing Boardman Power Plant in northeastern
Oregon. The Hemingway-Boardman Transmission Line Project’s proposed and
alternative routes are shown in Figure 1. The Hemingway-Boardman Transmission
Line Project scheduled in-service date will be no earlier than 2020.
Path 14 transfer capacity ratings with the Hemingway-Boardman Transmission Project
facilities are expected to increase to 2250 MW west to east (a 1050 MW increase) and
a 3400 MW east to west (a 1000 MW increase). Project facilities are listed below:
Hemingway-Boardman 500 kV line, 300 miles with approximately 50% series
compensation (split equally at each end); the western termination will be at the
Grassland switching station near the Boardman Power Plant
Hemingway 500 kV Line Terminal with Shunt Reactors and Series Capacitor

Conductor Bowmont, 2nd 230/138 kV 300 MVA Auto-Transformer
The Hemingway-Boardman Transmission Project will conform to the NERC TPL-001-4
Standard and other corresponding regional System Performance requirements at the
time, if any,. and the WECC “Overview of Policies and Procedures for Project
Coordination Review, Project Rating Review, and Progress Reports.”
A Hemingway-Boardman Transmission Project Comprehensive Progress Report
(Phase I) was released for comment in November 2008 and was granted Phase II
status in March 2009. Idaho Power began the Phase II study process in 2011; the
initial kick-off project review work group meeting was held on June 22, 2011, and the
second project review group meeting was held on November 15, 2011.
The third project review group meeting was held on March 22, 2012. On August 10,
2012, a conference call/webinar was held to solicit comments on the initial Phase II
draft report. In August 2012, Idaho Power submitted the Idaho-Northwest Up-rate,
Hemingway-Boardman 500 kV Transmission Project Phase II Report to WECC and
was granted Phase III status on November 29, 2012 with an Accepted Rating of 2250

The 230 kV looped connection in and out of the Rattlesnake switching station,
currently installed in the Midpoint-Boise Bench 230 kV #2 line, will be relocated to the
Midpoint-Boise Bench 230 kV #1 line between DRAM and Justice. Both 230 kV lines,
as well as the Midpoint-Boise Bench 230 kV #3 line, are all part of Idaho's internal
Midpoint West path. In addition to the relocation, the series capacitor banks at Midpoint
on the #2 and #3 lines will be replaced and increased to 70% comp each. These
upgrades are being done to gain approximately 275 MW of east to west transfer
capability across Midpoint West with the added benefit of approximately balancing the
flows on the Midpoint-Boise Bench 230 kV #2 & #3 lines. We expect the in and out
relocation for Rattlesnake to be completed in June of 2015. We expect the series
capacitor bank replacements to be completed sometime in the fall of 2015. This project

The Gateway West project was jointly announced by Idaho Power and PacifiCorp
(Rocky Mountain Power) in May 2007, to build and operate approximately 900 miles of
new high-voltage transmission lines between the Windstar substation near Glenrock,
Wyoming and the Hemingway substation near Melba, Idaho. The Gateway West –
Stage 1 project will include approximately 150 miles of 230 kilovolt (kV) lines in
Wyoming and approximately 800 miles of 500 kV lines in Wyoming and Idaho.
Gateway West– Stage 2 transmission facilities primarily consist of a second set of 500
kV circuits from southern Wyoming to western Idaho.
PacifiCorp reported in the 2011 Annual Progress Report submission that the third party
requests and financial commitments that are necessary to support the Energy
Gateway – Stage 2 facilities have not materialized. Therefore, PacifiCorp indicated that
it would continue to pursue WECC path ratings for Stage 1 of Energy Gateway only at
that time, and will not further pursue ratings for Stage 2 facilities. This Energy
Gateway Project status update was also reported to TSS at the April 20-22, 2011,
meeting in Westminster, Co.
For Gateway West – Stage 1 transmission paths located west of Populus [specifically
Borah West and Midpoint West], Idaho Power was the project sponsor for each of the
path ratings studied; additionally for Gateway West transmission paths located east of
Populus [specifically TOT 4A, Aeolus West, Path C and Bridger/Anticline West],
PacifiCorp was the project sponsor for the path ratings studied. At the completion of
the Phase 2 path rating process, TOT 4A transmission path was granted Phase 3
status on December 13, 2010; Aeolus West, Bridger/Anticline West and Path C
transmission paths were granted Phase 3 status on January 5, 2011; and Borah West
and Midpoint West transmission paths were granted Phase 3 status on July 21, 2011.
Both the Gateway West and Gateway South siting and permitting requirements are
currently being reviewed separately under the National Environmental Policy Act
(NEPA) process. Future changes to the Energy Gateway Project facilities and
configuration may be influenced by the NEPA process and permitting requirements
until this process concludes, which today expected to conclude for Gateway West in

Richfield, Utah to the Red Butte substation in southwestern Utah. PacifiCorp is leading
the planning effort and managing the WECC rating process for the project. The
Gateway South project entered Phase 2 in January 2009. Of the transmission paths
associated with the project, the Aeolus South path was granted Phase 3 status on
December 16, 2010 while the TOT 2B/2C Paths should be granted Phase 3 status in
the first quarter of 2011. PacifiCorp is proposing this transmission project because of
native load growth and the need to deliver renewable resources from Wyoming to
PacifiCorp retail load centers. PacifiCorp forecasts that its load on the Wasatch Front
of Utah will double in the next 20 years. Additionally, PacifiCorp has an independent
obligation, pursuant to its Open Access Transmission Tariff, to plan for and expand its
transmission system based upon the needs of its native load and network customers
along with eligible customers that agree to expand the transmission system.

0.1
The Horizon Phase II Project mitigates potential overloads to the Horizon 230/115
kV transformer for base case and single and double contingencies during peak
summer loading conditions. In addition, this project mitigates potential overloads
on the local area 115 kV system for double contingencies during peak summer
loading conditions. PGE plans to build out the Horizon substation breaker-andonehalf bus configuration and install a second bulk power transformer at Horizon
substation. The installation of this transformer dictates the need to replace
seventeen 115 kV circuit breakers at Sunset substation to mitigate fault duty
concerns; a second 115 kV capacitor bank will also be installed at Sunset substation
to provide voltage support. To provide a second source to Horizon substation, PGE
will construct a new 4.4 mile 230 kV line segment between Horizon substation and
Springville Junction. This line segment will tie into the existing St Marys-Trojan 230
kV circuit, creating a Horizon-St Marys-Trojan 230 kV circuit. The bulk power
transformer will be energized by June, 2017; and the new 230 kV line segment will
be energized by June, 2018.

The project starts at PGE’s Coyote Springs generation plant located in the town of
Boardman, OR, and ultimately terminates with the installation of a new 500/230 kV
transformer bank at PGE’s Bethel Substation located in Salem, OR. The Boardman
and Coyote Springs substations will be expanded to accommodate the project. PGE
will need to acquire approximately 30 miles of new ROW for the Boardman to Coyote
Springs 500 kV line. After the Boardman substation the project will connect to new
wind resources being developed in Gilliam and Wasco counties in Oregon. The
project will parallel existing utility lines whenever possible by acquiring additional ROW
for approximately 180 miles along the route into Salem, where the line will terminate at
an expanded Bethel substation.
On June 3, 2013, Portland General Electric suspended permitting and development of
the proposed Cascade Crossing Transmission Project. Changing market conditions
have created opportunities to explore lower-cost alternatives for customers and
provide the needed transmission capacity for PGE with reduced environmental
impacts.

“
This project had been titled “Lakeside Substation 230 kV Transformer Addition” in
progress reports prior to 2013.
The project will involve installation of a 230-115 kV transformer at an existing or future
PSE Substation. This project includes new construction of 230 kV lines or rebuilding
existing 115 kV lines, energizing at 230 kV to provide a source to the new transformer
and adding transmission capacity. Installing this transformer will address NERC
planning criteria and provide additional capacity to serve the projected load growth in
north central King County and surrounding areas.
The attached document, ‘Eastside Transformer Project.pdf’, shows the possible
locations and associated transmission routes.
ColumbiaGrid is a Subregional Planning Group in the Pacific Northwest and has open
participation in its planning meetings and the Puget Sound Area Study Team (PSAST).
This project has been developed by and has achieved consensus via the
ColumbiaGrid PSAST, which included all the transmission owners that could be
impacted by this project. The “Eastside 230 kV Transformer Addition and Line
Rebuilds” project began to be studied by the PSAST in mid-2009, and was in PSE’s
Annual Progress Report last year. The most recent report is entitled “Updated
Recommended Transmission Expansion Plan for the Puget Sound Area to Support
Winter South-to-North Transfers”, June 17, 2011. The report recommends this project
and four other transmission improvements, and is available from ColumbiaGrid
www.columbiagrid.org. The requirements of project coordination review for this project
have been met through the ColumbiaGrid acting as a Subregional Planning
Group.
The attached document, ‘WECC Comprehensive Project Coordination Review
Letter_PSAST 2-21- 13.pdf’, describes the coordinated ColumbiaGrid study efforts.
The energization date for the Eastside 230kV project has been pushed out since this

Install a new 230 kV line From Pony Express Switching Station (Enel) to a new 230/60
kV substation (approximately 1/2 mile South of Fallon) and build a series of
substations and switching stations (Pony Express, Bunejug, and Macari) to provide
new source, via a 25 mile 230 kV line, to the City of Fallon. The projected in service
date for this project is June 2014. The scope of this project has been changed due to a
reduction in load growth in Fallon area, the termination of one LGIA and the reduction
in a second LGIA have also contributed to the reduction in scope of this project. The
project will now likely to be a 10 mile 230 kV generator lead line heading southward
from the generator interconnect, company BO, with a reduced LGIA to the Pony
Express Switching Station. The Pony Express switching station will be constructed at
an existing generator interconnection site (Enel) and then connects to NV Energy’s
Northern 230 kV system about five miles further south. No connection will be made
from into Fallon from interconnection BO switching station.

It is not unusual for projects of this scale to test the market a number of times. The
fact that a project is not successful in one open season does not mean that a project

Havre to Rainbow 161kV
Rebuild / Upgrade
161
2022
.75
This project is on-hold status due to high priority oil load growth. Western’s 103 mile
Havre – Verona – Rainbow 161kV transmission line was constructed and energized in
1935. It electrically parallels NorthWestern Energy’s (NWE’s) Havre – Rainbow 161kV
circuit. These two circuits maintain separate rights-of-ways with two crossings.
Western intends to rebuild its circuit in segments, at 230kV specification. Each
segment is anticipated to be complete and re-energized in approximately one month.
The existing right-of-way is inadequate and will be expanded in most areas and rerouted in others. An Environmental Assessment (EA) is complete for this project and
has been issued for final publication. The first 30 mile segment between Havre and
Verona is complete, along with 1 mile at the Rainbow / Great Falls end for retermination into NorthWestern Energy’s (NWE's) Great Falls Substation in conjunction
with Project 2) described below. In 2011, 14 miles of reroute and reconstruction began
in the Loma, MT area and was approximately one-third complete when crews were redispatched due to storm damage in Eastern Montana / Western North Dakota (East
Grid WAUE BA). Due to both storm damage and dramatic oil exploration load growth
in the Eastern Montana / Western North Dakota area, this project has been placed onhold for approximately 5 years, with approximately 5 years of construction remaining
prior to completion. Therefore, target completion is estimated to be 2022. Once the
project resumes, construction will again continue during non-peak loading periods only.
Upon completion of each segment, the line will continue to be energized at 161kV until
such time that conversion to 230kV is required. Additional system impact study
analyses will be required with stakeholder approval prior to the 230kV voltage
conversion. No interruption of customer service during construction is anticipated with
this project. The project will receive a single 1 mile reroute this summer, near Carter, to
raise the highway crossing for accommodation of extra large/tall shipments of prefabricated tanks North of Great Falls, MT.

Western currently owns, operates and maintains the Havre 161/115/12.47kV
Substation. Upgrades are a result of needed relaying replacements and a new 115 kV
interconnect for network load. The existing 115 kV single breaker and bypass switch
will be replaced with a ring bus configuration serving the existing Shelby circuit and
new network service interconnect. In addition, a new dedicated circuit interrupter will
be installed for protection of the transformer. Construction design is complete. The
control building was completed 2012 and currently is receiving protective relaying
upgrades. Completion of the 115 kV yard work is expected by fall of 2014. The 115 kV
bus will be out of service for extended periods during the 2014 construction season.
However, no interruption of customer service during construction is anticipated. Minor
outages are expected for Hill County Electric Coop during sequenced re-energization.
Herron Park is currently served via a temporary tap off the Havre-Shelby 115 KV line.

This project is on-hold status waiting for regulatory approval. Western currently owns,
operates and maintains the 180 mile Fort Peck-Richardson Coulee-Malta-HarlemHavre 161kV circuit, which is constructed for future 230kV conversion. A new
substation is anticipated to be installed approximately 18 miles East of Malta in the 49
mile section between the Richardson Coulee and Malta Substations. This new
substation will provide a 161kV ring bus constructed at 230kV specification, 161/115kV
transformation and a 115kV tap for a new 115kV line that will extend approximately 48
miles to serve an ultimate 21 MW of new oil development network load. VAR support
will include a 15 MVAR shunt capacitance at the new 161kV substation and a 15
MVAR shunt capacitance at the load. Due to regulatory delays, construction is not
anticipated to begin before fall of 2014. No interruption of customer service during
construction is anticipated.

This project consists of the addition of a second 345/230kV 600MVA
transformer at the Laramie River Station (LRS) switchyard in southeast
Wyoming. It will connect to the existing 345kV and 230kV buses within the LRS
switchyard. The in service date is August 2014. The transformer will be owned
by the Missouri Basin Power Project (MBPP). This transformer will primarily
function as an in service spare unit for the MBPP. No increase in system intact
path ratings is expected; therefore the WECC path rating process is not
necessary. Prior outage limits on the TOT3 path and LRS generation limits may
be increased as determined by future operating studies. Under some conditions
a LRS generation prior outage can contribute to TOT3 limits due to overload of
the existing transformer. Also prior outage of elements of the LRS 345kV
transmission system can cause LRS generation limitations due to overload of
the existing transformer. The second transformer will improve system capacity
in these situations.

Rocky Ford/La Junta area.
The project consists of a new double circuit 115 kV line between Boone 115 kV
and Nyberg 115 kV substations, utilizing existing right-of-way where possible
and replacing the Boone – DOT Tap – Nyberg 115 kV transmission line. New
115 kV line terminal positions are required at Nyberg and Boone 115 kV
substations to integrate the new circuit.
The Colorado Coordinated Planning Group (CCPG) is a Sub regional Planning
Group in the Rocky Mountain Region and allows open participation in its
planning meetings to stakeholders interested in this project. The requirements
of project coordination review for this project have been met through the CCPG.
The planned in-service date is 2015.

b) Currently, there is only one transmission line from the CSU-owned Front
Range Power Plant that generates 460 MW at summer peak. The purpose of
this project is to provide a second line out of the plant to connect with an
existing CSU transmission line.
c) The termination point for the existing 230kV NX-KE line will be removed from
the Nixon 230kV bus and the line will be re-routed into the Front Range Power
Plant substation which it is only a few hundred feet from the existing line.
Rather than two identical NX-KE lines, CSU will now have one 230kV line from
Nixon to Kelker and one 230kV line from Front Range Power Plant to Kelker.
d) The expected date of release to operations is December 2015.
e) The expected operating voltage is 230kV.
f) The project is not expected to have a significant impact on the operation of
the WECC interconnected electric system because CSU is a small, relatively
self-contained system. Changing the termination point of this existing 230kV
line has very little impact on the CSU system and even less impact on the
WECC system. The project provides a reliability improvement for CSU under
certain Category C or D outages.

This project includes two high voltage transmission paths, one from Lamar
substation to Pueblo area and a second from Lamar to substations near Brush
and/or Deer Trail. This will provide for better reliability to serve loads in the
entire eastern Colorado footprint. Multiple voltage options have been examined.
This project will be built in stages, with each designated stage being a part of
the overall plan to address the eastern Colorado transmission needs. This
project will also provide the infrastructure for Xcel Energy to meet Senate Bill
07-100 requirements by connecting several Energy Resource Zones in eastern
Colorado to the Denver Front Range area.
“
The purpose of Burlington-Lamar Transmission Project is to incrementally
alleviate existing and future transmission system constraints in southeast and
eastern Colorado as identified in the Lamar Front Range studies. It is a subset
of the greater Lamar Front Range project. To accommodate future build outs,
the Burlington-Lamar line may be constructed for 345 kV operation, but will
initially be operated at 230 kV.
“
This project involves constructing a new 230 kV transmission line from Casper
substation to Badwater (PACE) substation. The new 70 mile long line will allow
improved reliability and allow Tri-State to serve new load near central
Wyoming. The planned in-service date is expected to be in 2018.
“
This project involves sectionalizing the Laramie River Station (LRS)-Story 345
kV line for a load serving connection approximately 60-65 miles northwest of
Story. Tri-State would install a 225 MVA, 345/115 kV transformer at Keota
substation, with the possible future addition of a second transformer. The level
of load planned for this substation is initially 40 MW, with a potential increase to
120 MW based on the most recent load connection requests. The planned inservice date is 2015. This project is in Phase III of the WECC Three Phase
Rating Process.
“
The Boone-Walsenburg project will consist of one new 230 kV transmission
path from the existing Boone substation, owned by Tri-State and Xcel Energy,
to the existing Walsenburg substation, owned by Tri-State. The conductor will
be 1272 MCM ACSR-Bittern with a maximum design temperature of 100°C and
be owned by Tri-State. Addition of a new 230 kV line will increase reliability in
the Pueblo, Colorado area and also in Northeast New Mexico. Presently, the
loss of the Comanche-Walsenburg 230 kV line results in severe thermal
overloading on the 115 kV transmission system from West Station to
Walsenburg. In order to mitigate the overloading, a Remedial Action Scheme
(RAS) trips the Walsenburg-Gladstone 230 kV line which results in the loss of
load and reduced reliability in Northeast New Mexico. The planned in-service
date is 2018.

and increase the deliverability of Tri-State resources to Tri-State member loads.
This will be accomplished by adding a new 230 kV line from the Burlington
substation to the Wray substation. The addition of the 230 kV line will add one
new transmission line segment that will be constructed as a single circuit using
1272 MCM ACSR conductor with a maximum operating capacity of 1538 amps.
This additional capacity will alleviate congestion in the Burlington area, increase
reliability, and allow the potential development of renewable generation
resources in the Burlington and Wray areas which currently have existing wind

The project consists of two basic sections and is a joint project with Xcel
Energy. The first section consists of approximately ninety‐five (95) miles of
new, double‐circuit 230 kV transmission, built from the San Luis Valley
Substation to a new Calumet Substation, which would be located approximately
six (6) miles north of the existing Tri‐State Walsenburg Substation. The second
section consists of approximately forty‐five (45) miles of 19 new double‐circuit
345 kV transmission line from Calumet Substation to the existing Comanche
Station near Pueblo. The project will improve local system performance and
reliability, and will facilitate potential generation as part of Xcel Energy’s
response to Colorado Senate Bill 07-100 which calls for development of
transmission facilities to deliver power from renewable resource zones in
Colorado. The project was initially planned to be in service in 2015. However,
the project in service date has been delayed and will be determined after
Colorado PUC and other stake holder input. This project is not expected to
impose any significant impacts on the reliability of the WECC interconnected
system.
“
The project is to add a 300 MVA Phase Shifting Transformer (PST) at the
Gladstone existing substation. Studies by Tri-State and others have all shown
the need for transmission network upgrades in the North East New Mexico
(NENM) area to improve system reliability, load serving capability, mitigate
operating issues related to phase angle differences, and to reduce system
losses. The planned in-service date for this project is 2018.
“
Tri-State’s J.M. Shafer generating station has a total capacity of 272 MW and
has some capability to be upgraded in the future. The station presently relies on
the 230kV Fort Lupton Substation and its interconnected transmission system
owned by Xcel Energy to deliver power to Tri-State’s loads in the PSCo
Balancing Authority area. Since Tri-State has load in both the PSCo Balancing
Authority area and the WACM Balancing Authority area, Tri-State desires the
flexibility to directly deliver the output of the J.M. Shafer station to either
Balancing Authority. Tri-State can do so by interconnecting the J.M. Shafer
station directly to the Greenhouse Substation and constructing a Greenhouse
to Henry Lake 230 kV line. Tri-State forecasts an increasing need for additional
balancing resources in the WACM BA to comply with the State of Colorado’s
Renewal Portfolio Standards. The J.M. Shafer to Greenhouse to Henry Lake
230kV project will permit Tri-State to utilize the J.M. Shafer station as a
balancing resource in the WACM BA. The project will also improve
transmission reliability by providing a second transmission source directly to the
J.M. Shafer station and mitigates the problem of losing the entire station for a
single line outage.

The original SunZia Southwest Transmission Project was envisioned to be
comprised of three segments of two 500 kV (AC) lines each from the renewable
resource energy zone(s) in central New Mexico (referred to in this report as
SunZia East) to the proposed Pinal Central 500 kV substation (to be operated
by Salt River Project) in central Arizona. SunZia examined two intermediate
electrical interconnections: one at a new SunZia South 500 kV substation near
the existing Luna 345 kV substation in southwestern New Mexico (to be
operated by El Paso Electric Company (EPE)), and another at the proposed

Willow 500 kV Substation (to be operated by Tucson Electric Power (TEP)) in
southeastern Arizona. Taken together with these two intermediate substations,
the three project segments are created: (1) SunZia East to SunZia South; (2)
SunZia South to Willow 500 kV; and, (3) Willow 500 kV to Pinal Central.
The modified POS will be changed slightly to exclude a 500/345kV transformer
at Luna and include only one intermediate electrical interconnection at the
Willow 500 kV Substation. The 3 SunZia South Substation will initially only
include a series capacitor bank (70% series compensation).
Additional information that is periodically updated is available at the SunZia
Project Website: www.sunzia.net.

The 85 mile NG-IV #2 500kV project is a major intertie expansion between the
North Gila area (southwest Arizona) and the Imperial Valley area (southern
California); this line would parallel the existing North Gila-Imperial Valley line
(also known as the Southwest Power Link, or SWPL), with an expected
separation of 250 feet from the existing SWPL. The potential for a second
circuit would be proposed to be constructed on the same set of structures, and
would potentially loop in and out of the existing Highline 230 kV substation
along the Highline Canal. The second circuit could be operated at 230kV
initially until the operational and scheduling need develops over the years to
potentially operate at 500kV. An additional alternative that we have been asked
to review by the PCRG is to have a single 500kV line and with the loop-in to the
existing Highline 230kV station. Review is currently underway of this
configuration.

be turned over to the ISO operational control, once IID complete the
construction of additional facilities required to interconnect the IV Policy
Element project to the IID electrical system.
The additional facilities required to interconnect the IV Policy Element to the IID
electrical system consist of a 230 kV Station (Fern) located in the north side of
Liebert Station; a 230 kV bus tie between Fern Station and Liebert Station, and
the connection of the 230 kV “S” line from El Centro Switching Station (ECSS)

The TE/VS Interconnect provides a high capacity link between the main
backbone of California to San Diego Gas and Electric’s (SDG&E) 230 kV grid,
providing the only 500 kV connection between the northern part of the SDG&E
system and Southern California Edison’s (SCE) 500 kV grid. By adding a
future link between the Sunrise Project’s 500 kV Central Substation and the
TE/VS Interconnects Case Springs Substation, a 500 kV loop could be formed
across the western section of the 500 kV lines from the Palo Verde area to
Serrano on the north and Imperial Valley on the south. The project will also
serve to connect the proposed 500 MW Lake Elsinore Advanced Pumped
Storage (LEAPS) into the western grid. The TE/VS Interconnect is being
permitted through the California Public Utilities Commission (A.10–07–001).

To accommodate LADWP’s planned renewable generation along the InyoRinaldi corridor LADWP is proposing the Barren Ridge Renewable
Transmission Project (BRRTP) to access potential wind, solar and other
clean, renewable resources from the Mojave Desert and Tehachapi
Mountain areas of Southern California. The project is in Kern and Los
Angeles Counties, and is approximately 77 miles in length from Barren Ridge
Switching Station (BRSS) to Rinaldi Substation and 12 miles in length from
Castaic Power Plant to the proposed Haskell Canyon Switching Station. The
project will consist of:
1. Construction of a 230 kV double-circuit transmission line from the LADWP
BRSS to Haskell Canyon Switching Station.
2. Addition of a 230 kV circuit on the existing double-circuit structures from
Haskell Canyon to the Castaic Power Plant.
3. Upgrade the existing Barren Ridge – Rinaldi 230 kV transmission line with
larger capacity conductors between the BRSS and the Rinaldi Substation.
4. Construction of a new switching station at Haskell Canyon.
5. Expansion of the existing BRSS.
The ultimate capacity between the BRSS and the Haskell Canyon Switching
Station is approximately 1600 MW, while the existing rating is 459 MVA. The
BRRTP is expected to have no regional impact.

The Mirant Marsh Landing Generating Station (MLGS), a proposed project near
Antioch, CA will consist of four Siemens Energy simple cycle combustion
turbine-generator units. The units will be located adjacent to Mirant’s Contra
Costa Power Plant and will interconnect to the existing PG&E Contra Costa
Power Plant 230 kV switchyard through two 230 kV transmission lines. Each
unit of the MLGS will have a net winter rating of 222 MW and a net summer
rating of 193.5 MW. The expected commercial operation date for the MLGS is
May 1, 2013.

Gates – Gregg 230kV Line
Project
230
12/2022
.5
This project is to construct a 68 mile long 230kV DCTL from Gates to Gregg
with one side strung. This project will improve reliability in the Greater Fresno
area, allow greater operational flexibility of the three units at the Helms Pumped
Storage Plant (PSP), and help integrate renewable resources within California.
Since the proposed Gates – Gregg 230kV line will be in parallel with the
existing Gates – Gregg 230kV line that is one of the Path 15 lines, this project
will trigger re-definition of Path 15.
In the 2012/13 Transmission Plan Process, the CAISO recommended and
approved the Gates - Gregg 230kV transmission line, constructed as a double
circuit line. One of the circuits is to be strung initially (by 2022 or earlier), and
the other will be strung in the future after demand has increased sufficiently
(anticipated in the 2025-2027 timeframe).
In June 2013, the consortium of PG&E, MidAmerican Transmission and
Citizens Energy submitted a bid to CAISO for the Gates-Gregg 230kV
transmission line and was awarded the project in November 2013.
