SUMMARY REPORT | 2014 10 -Year Transmission System Assessment
A changing landscape
www.atc10yearplan.com
SUMMARY REPORT | 2014
The changing landscape of the energy
industry requires an understanding of all
grid functions, not just connecting power
plants to communities.
and location of
generators require us
to work closely with the
generator owners, MISO,
and other stakeholders
to determine how we
will continue to provide
reliable service.
We continue to work with
stakeholders when considering
such traditional planning elements
as changes in load, usage and
possible generator retirements. Load
on our system varies significantly
across our service area; while
load growth has slowed in recent
years, our plans must account for
differing needs driven by geography,
population, energy-intensive
industries, changes in the general
economy and other variables.
Such is the case with our Bay Lake
Project – a combination of new
138-kV and 345-kV lines in the
northern part of our service area.
The lines are designed to address a
delicate, shifting balance between
generation, load and transmission.
A large percentage of load in that
portion of our system runs nearly
continuously, making it difficult to
schedule maintenance outages for
transmission system components.
When maintenance is performed
while the system operates at
near-capacity, the risk of losing
service to customers is higher.
At the southern end of our system,
transmission congestion has
often prevented our customers
from buying and selling the most
economic power available in the
region. The Pleasant Prairie‑Zion
Energy Center line, our first
Midcontinent Independent System
Operator-approved Multi‑Value
Project, was placed into service
late last year and began providing
benefits immediately. In fact, earlier
this year, one of the Wisconsin
utilities announced plans to return
money to its customers as a
result of increased sales to other
utilities. We believe that this
new MVP line was an important
factor that reduced congestion,
helping the sales increase.
We continue to be challenged by
significant changes in generation.
Some generators have retired,
others have announced retirements
and we have added new generation
to the system. The changing mix
and location of these generators
require us to work closely with
the generator owners, MISO and
other stakeholders to determine
how we will continue to provide
reliable service with these changes.
High-profile events such as acts of
terrorism and vandalism have placed
increasing emphasis on physical and
cyber security measures. A new
mandatory Critical Infrastructure
Protection standard is expected to
be issued by the Federal Energy
Regulatory Commission soon. We
have launched a targeted, 10-year
program to enhance security at
many of our substations based on
a risk methodology that assessed
our threats and vulnerabilities.
We also are involved in industry
discussions to address additional
ways to maintain the safety and
security of the electrical grid.
The 2014 Assessment covers the
years 2014 to 2023 and indicates a
need for $3.3 billion to $3.9 billion in
transmission system improvements.
The planning zone summaries
included in this report detail some
of the specific projects identified
to improve reliability, access to
the market and renewable energy
resources. A more comprehensive
listing of these projects is available
at www.atc10yearplan.com.

10 -Year Transmission System Assessment
The changing mix
For several years, we have been
discussing evolving energy markets,
the need for regional planning
to provide economic benefits,
and the ways technology and
public policy are challenging and
changing the way we plan and
operate the grid. New variables
enter into consideration each year.
Consequently, industry dynamics
require an ever-expanding view and
understanding of all the benefits
of a strong transmission grid.
SUMMARY REPORT | 2014
Regional and economic planning update
Eastern Interconnection
Planning Collaborative
Building on a planning initiative
started in 2010, a group of 25
registered planning authorities
continues to refine plans for
transmission grid needs from the
Rocky Mountains to the east coast
and several Canadian provinces.
Recent “stress test” studies
performed by the collaborative show
that the system has the potential to
increase transfers in 2018 by 1,100
megawatts to 5,000 megawatts. In
2023, transfers could be increased
between 550 and 5,000 megawatts,
depending on the regions involved.
These transfers are in addition to the
transfers that already take place in
the base case and would involve no
transmission being built other than
what is already included in existing
plans across the interconnection.
Two additional scenarios using
2018 and 2023 models are being
studied using updated plans from
the previous study and a drought
scenario in part of the Eastern
Interconnection with transfers
coming from non-drought areas.
Market constraints
Two of the three narrow constrained
areas identified in the MISO region
are associated with ATC. The two
areas are within the Wisconsin and
Upper Michigan System. Congestion
within the northern WUMS study
area declined significantly since
2012 due in part to transmission
upgrades and generation additions.
The Pleasant Prairie-Zion Energy
Center MVP transmission line also
has helped alleviate congestion. We
continue to evaluate projects that
may eliminate the NCA designation.
MISO Transmission
Expansion Planning
MISO planning studies address longand short-term issues as well as
targeted needs. Long-term studies
primarily look at value-based options
that provide economic benefits in
the 10- to 20-year horizon. Shortterm planning is primarily driven by
transmission owners’ reliability and
NERC compliance needs in a five- to
10-year period.
MTEP 14
Our staff participates in the shortterm reliability and economic studies
in a variety of ways: ensuring
accurate project information is
included in the MISO database,
building and reviewing models,
correlating needs identified by MISO
analyses with specific ATC projects
and participating in various studies
and stakeholder forums.
Other MISO planning
activities
Our Strategic Projects staff
participates in various technical and
policy discussions and provides
future direction of MTEP activities.
We also are involved in joint
planning studies with neighboring
regional transmission organizations,
including PJM and SPP. MISO and
PJM coordinated, conducted and
analyzed several Market Efficiency
Project studies. This analysis is
reviewed by an inter-regional
planning stakeholder advisory
committee and typically examines
economic projects that could benefit
both RTOs and qualify for crossborder cost-sharing.
FERC Order 1000
We also have participated in
MISO’s efforts to implement a
competitive bidding process for
selecting developers of Market
Efficiency Projects and MVPs as
part of its compliance with FERC
Order 1000. ATC has applied to
become a qualified developer
and also has participated in the
stakeholder process for drafting the
business practice rules for selecting
developers.
In May 2014, FERC accepted
revisions to our local process to
comply with requirements that
transmission needs driven by public
policy requirements be considered
in planning.
4–5
4–5
10 -Year Transmission System Assessment
ATC is involved with several
planning efforts that address
regional, inter-regional and Eastern
Interconnection-wide needs that
could impact grid operations.
Proposed legislation regarding
renewable energy developments
and greenhouse gas emission
reductions continues to evolve at
the federal level. ATC monitors
these discussions and continues
to undertake internal analyses and
participate in regional studies to
anticipate the future demands on
the transmission system.
SUMMARY REPORT | 2014
Pleasant Prairie-Zion
Energy Center
Reliability and Multi-Value Projects strengthen
the grid within our service territory
We also are developing a preliminary
southeast Wisconsin-northeast
Illinois 345-kV transmission project
to further address reliability issues
at this interface. While it has not yet
been identified in the specific project
list, it has been considered in the
capital forecast.
Mackinac HVDC
Converter Station
This unique facility to help
manage the flow of power across
transmission lines in Michigan’s
Upper Peninsula was placed into
commercial operation in summer
2014. The station, located adjacent to
the Straits Substation in St. Ignace,
Mich., is one of only three facilities
of its kind in the United States.
The device allows MISO to control
power flow in and out of the Upper
Bay Lake
The Bay Lake Project is a package
of proposals to address the
delicate, shifting balance between
generation, load and transmission
in the northern portion of our
service area.
The Holmes-Old Mead Road portion
of Bay Lake was approved by
Michigan regulators in early 2014.
It includes a single 58-mile, 138-kV
line from the Holmes Substation
in Menominee County to the Old
Mead Road Substation in Escanaba,
Mich. Construction of the $120
million project is scheduled to begin
in late 2014 with an in-service date
of mid-2016.
The North Appleton-Morgan project
includes a 345-kV and 138-kV line
from our North Appleton Substation
in Outagamie County to the Morgan
Substation in Oconto County, Wis.
Both substations will be expanded
and a new substation, Benson Lake,
will be required to accommodate
a large voltage-control device at
the site of our Amberg Substation
in Marinette County. Additional
work will be required at 11 other
substations. The project is currently
being reviewed by the Public
Service Commission of Wisconsin.
If approved, construction would
begin in 2017 with an in-service date
of 2019. Cost of the project ranges
from $307 million to $327 million
depending on the route selected.
ATC has initiated a Northern Area
Reliability Assessment effort to
engage stakeholders and identify
potential reinforcements due to
generation uncertainties in the
northern portion of the ATC system.
While not yet specifically identified
in the project list, the capital forecast
includes consideration of preliminary
alternatives that could include:
-- Plains-National project
-- Lakota-Winona conversion from
69-kV to 138-kV
-- Morgan-Crivitz project
-- Uprates or rebuilds in the
Green Bay area
-- Rhinelander area upgrades
ATC is collaborating with MISO to
complete this assessment in late
2014. Potential generation solutions
also will be considered.
Badger Coulee
Badger Coulee, one of the
17 Multi‑Value Projects proposed
by MISO in late 2011, also is being
reviewed by the Wisconsin PSC.
The 160- to 180-mile 345-kV line
between the La Crosse and Dane
County areas will deliver reliability,
economic and public policy
benefits. Sponsored jointly with
Xcel Energy, the project will
n
Offset the need for about
$160 million in lower-voltage
upgrades in western Wisconsin,
n
Increase access to the
wholesale energy market
and could provide between
$259 million and $841 million in
net economic benefits over the
life of the project and
n
Establish another pathway
for renewable energy into
Wisconsin with a connection to
key load centers.
Cardinal-Hickory Creek
This project between Dane County,
Wis., and Dubuque County, Iowa,
is a 125-mile line that will provide
benefits that exceed its cost. As
a joint venture with ITC Midwest
LLC, this MISO Multi-Value Project
would improve local and regional
reliability and deliver economic
benefits by providing greater
access to the wholesale market.
The 345-kV line would run from
the Cardinal Substation in Dane
County, to the proposed Hickory
Creek Substation in Dubuque
County. Initial Wisconsin public
outreach for routing and siting the
line will begin in fall 2014.
6–7
10 -Year Transmission System Assessment
Major projects update
As noted in our opening letter, this
project began producing economic
benefits as soon as it was placed in
service in late 2013. The 5.3-mile,
345-kV line between substations in
Pleasant Prairie, Wis., and Zion, Ill.,
relieves congestion in the region and
provides savings to electric utilities
and their customers by enabling the
most efficient generators to supply
power to the energy market. It also
has increased local and regional
reliability by providing another
interstate high-voltage connection for
utilities in Illinois and Wisconsin.
Peninsula, helping to accommodate
the transmission of renewable
wind energy being developed in the
west. The station was a quick and
less-expensive solution compared
to a portfolio of transmission lines
studied as alternatives.
Since we were formed in 2001 as a utility solely
focused on electric transmission, we have:
n u
pgraded more than 1,824 miles of transmission line,
n improved 165 electric substations and
n b
uilt 48 new transmission lines (600 miles)
Our progress
performance in line
reliability in 2013
highlighted by a
“Best in Class”
Transmission Reliability
Composite Score for
100‑ to 161‑kV lines.
Today, we have a more robust
network and have established more
connections to systems in other
states. But a regional energy market
is maturing, the grid is being asked to
perform in ways it was not originally
intended, and our interconnected
customer needs continue to change
based on economics and public policy
regarding air quality issues. As a utility
company with an obligation to serve,
we work closely with our customers
not only to provide reliable service,
but also to share information about
how changes in their operations
impact our system.
Regional planning has become a
logical outgrowth of a geographically
broader energy market. As new air
quality rules take effect, older coalfired generation will be retired and
replaced with newer generation,
including renewable energy
developments in areas with a rich
wind resource but without large
load centers. Transmission system
expansion or reconfiguration of the
system will play an important role as
changes are made in generation.
Managing our existing assets goes
hand in hand with our planning
strategy for maintaining and improving
reliability and cost-effectiveness.
Our Quad County Electric Reliability
Project is a major maintenance effort
to replace aging lattice and H-frame
structures and wires on lines in
Waukesha, Jefferson, Dodge and
Washington counties in Wisconsin.
Originally built in the late 1940s, the
58 miles of 138-kilovolt transmission
lines will be upgraded to include fiber
optic wires on portions of the project,
providing high-speed data transfer and
overall support to the electric system.
ATC line reliability maintained top
performance in 2013, highlighted
by a “Best in Class” transmission
reliability composite score for 100‑ to
161-kV lines, and ranked in the top 10
percent for 345- to 500-kV lines. While
lines are performing well, targeted
investment is required to maintain
reliability.
Transmission remains a good
value for the electricity consumer.
Transmission costs within our service
area remain at about 8 to 9 percent of
a retail customer’s electric bill. Retail
customers pay for the generation,
transmission and distribution of
electricity, plus fuel costs, through
regulated utility rates. Generation
and fuel make up the major portion
of the bill, followed by distribution
infrastructure.
We have made progress by actively seeking input
and making our plans and proposals public. To date,
ATC has:
n produced and issued 19 transmission system
assessments to the public,
n h
eld dozens of major public planning and siting
meetings and
n p
articipated in thousands of interactive local,
state and industry discussions, both giving and
receiving information to carry out our duties and
responsibilities.

ATC maintained top
The landscape in which we operate
today looks vastly different than it
did when we began our operations
in 2001. Then, we were operating a
balkanized system of transmission
assets with few interconnections
with each other, let alone connections
with other states. There was little
operating margin, especially during
times of peak demand in the summer.
A more reliable transmission system has enabled us to:
n r
eliably deliver electricity to customers in Wisconsin,
Michigan and Illinois at all hours of the year including
peak demand hours,

SUMMARY REPORT | 2014
Major accomplishments to date
Plans and proposals
for the transmission system
Economics – We evaluate the impact
of transmission congestion on wholesale power prices and study projects
to determine economic savings to
offset most or all of the congestion and
loss costs. An example is evaluating
increased access to markets outside
our footprint.
Solutions: Two projects based on
economics have been completed and
two more are proposed.
For planning purposes, we divide our service area into five zones representing distinct geographic
or usage areas. Within each zone (shown below), we compile and assess the transmission system
needs.
Generator retirements – Similar to
new generator requests, when a large
generator is retired due to age or other
reasons, we will determine how system
requirements will be affected. Changing
economics, age and recently issued
EPA rules are expected to impact
retirements across the U.S. in the next
five to 10 years.
Solution: We are working closely
with generation owners and MISO
to anticipate reliability impacts to our
transmission system.
New generation – When a new generating facility is proposed, we conduct a
system impact study and, if requested,
a facilities study. If the existing transmission system is inadequate to ensure
generator stability or reliable transmission service, we will determine what
system expansion will be needed.
Solutions: 12 generators are
active in the ATC footprint of the MISO
generation queue, and many reflect the
growing development of wind energy
and natural gas.
24 generators added since 2001
required construction of transmission
facilities.
Asset renewal – Keeping transmission
lines, substations and related
equipment in good operating condition
extends the life of the facilities,
improves system performance and
safety, and minimizes the potential
for outages. Part of the $3.3 to
3.9 billion investment ATC will make
over the next 10 years is dedicated
to asset renewal. Major projects at
substations include replacing circuit
breakers, protective relays, lightning
protection and transformers. Major
work on transmission lines involves
rebuilding or upgrading aging power
lines, including the replacement of
structures, conductors, insulators and
other equipment.
Solutions: More than 110 projects
to address asset renewal needs are
anticipated in the next 10 years.
Load growth – Demand for electricity
during peak usage periods is forecasted
to grow at a rate of approximately
0.7 percent across our service
territory from 2015 through 2024.
Solutions: More than 90 projects
are planned for assuring reliability,
at least in part, due to load growth.
Approximately 3 projects were
cancelled, in part, due to slower load
growth rates.
Regulatory environment – Physical
and cyber security and reliability
standards continue to increase, which
may affect planning criteria and facility
design standards.
Solution: We are participating in
the North American Electric Reliability
Corp.’s standards development process
to help anticipate the future impacts of
these changes on our planning criteria
and facility design standards.
Integration of new technologies –
Demand-side management, variable
generation, distributed resources and
smart grid technologies all require
changes in how the grid is planned and
operated to maintain reliability.
Solution: The type of flow-control
device between Upper and Lower
Michigan will be one of three utilized
in the U.S.
Project classifications
Within each zone, we have recommended network and asset renewal projects to address
system limitations. The network projects are classified into one of three possible categories –
Planned, Proposed or Provisional – depending upon the stage a project may be in.

10 -Year Transmission System Assessment
Public policy – Pending air quality
regulations, a maturing wholesale
energy market and renewable energy
mandates have introduced uncertainty
and complexity in transmission
planning.
Solutions: We work closely with
our customers to determine what
changes in their operations will impact
the transmission system. We also
are participating in several regional
transmission studies to identify the
transmission needed to integrate
renewable generation, including wind,
much of which could be located in areas
remote from large load centers.
Distribution interconnections –
The transmission system is dynamic;
changes in load forecasts, replacing
aging distribution facilities, new
customers and existing customers
adding load all drive the need for
additional and/or modified transmissionto-distribution interconnections.
Solutions: 110 are planned in the
next 10 years. More than 362 new or
improved T-D interconnections have
been made since 2001.

Transmission system
limitations in Zone 2
There are a number of transmission
system performance issues in Zone
2 including limited ability to import or
export power, generator instability,
overloaded lines and equipment,
low system voltages and chronic
limitations to transmission service.
Primary drivers of these issues include
a mismatch of load to generation in the
Upper Peninsula and aging facilities in
poor or obsolete condition. In addition,
other studies occurring in parallel with
this Assessment, including Northern
Area Studies performed by ATC and
MISO, have identified several voltage
and thermal limitations. The most
severe limitations occur during off
peak periods.
While not specifically identified in the
project list for this assessment, ATC’s
capital forecast does include dollars
in anticipation of reinforcements
needed to address pending generation
retirements, such as the White Pines
and Presque Isle plants. Potentially,
Electric System Overview
Small increases expected in
population, employment
Population in Zone 2 is projected
to grow about 0.4 percent annually
between now and 2023, and
employment is expected to grow
about 0.8 percent each year in the
same time period. Marquette County,
Mich., is projected to realize the
largest increase in employment, while
Florence County, Wis., is projected to
have the highest growth rate.
Electricity usage
Zone 2 typically experiences peak
electric demand during the winter
months. Ore mining and paper mills
are the largest electricity users in
the zone.
Electric load is forecasted to increase
by 0.5 percent annually through 2024.
Also, locally generated electricity is
declining in the area with smaller,
coal-fired generators most at risk. This
includes generation owned by industry,
municipalities and utilities.
16 – 17
10 -Year Transmission System Assessment
ATC delivers power in Zone 2 with
various transmission facilities including:
n Morgan-Plains and Plains-Dead River
345-kV lines,
n P
lains-Stiles 138-kV double-circuit
line
n Lakota Road-Plains 138-kV line, and
n 138-kV facilities tying the Upper
Peninsula of Michigan to Lower
Michigan.
the scope of the project to address the
White Pine retirement might include
conversion of the 69-kV facilities
between the Conover Substation in
northern Wisconsin and the Winona
Substation in Michigan to 138-kV
operation. The potential scope of
additional solutions to address the
Presque Isle retirement could include a
Plains-National project as well as other
upgrades in Zones 1 and 4.

Rockdale-Wempletown
345-kV line,
Rockdale-Cardinal 345-kV line, and
38-kV facilities from the Nelson
1
Dewey Power Plant, around
the Madison area, and in the
northwest and southeast portions
of Zone 3.
Transmission system
limitations in Zone 3
In our analysis of Zone 3, we
identified low voltages, high
voltages and transmission-facility
overloads. Low voltages are located
in the Verona, Lake Geneva and
Hustisford areas. Several overloads
on 138-kV and 69-kV facilities in
Zone 3 are emerging concerns. The
causes of these emerging issues
include steady growth in certain
areas, power plant retirement
and different generation dispatch
scenarios.
Increases expected in
population, employment
Population in Zone 3 is projected
to grow about 1.0 percent annually
between now and 2023, and
employment is projected to grow
about 1.3 percent each year for
the same time period. Dane
County is projected to realize
the largest increase in population
and employment
Electricity usage
Electric load is forecasted to grow
approximately 1.2 percent annually
through 2024 for all of Zone 3.

Transmission system
limitations in Zone 4
In our analysis of Zone 4 we
identified potential high voltages in
the Outagamie and Calumet County
areas and low voltages in the Brown
County area. In addition, other
studies occurring in parallel with this
Assessment, including Northern
Area Reliability Assessment, have
identified several voltage and
thermal limitations. The most severe
limitations occur during the off-peak
periods. See the Zone 2 section for a
summary of a preliminary preferred
alternative.
Increases expected in
population, employment
Population in Zone 4 is projected to
grow 0.8 percent annually between
now and 2023. Brown County is
expected to realize the largest
increase in population. Employment
is projected to grow 1.0 percent
annually in the same time period,
with the largest increase projected
in Brown County.
Electricity usage
Peak electric demand typically
occurs during the summer months,
although the northern portion
of Zone 4 typically experiences
nearly equal summer and winter
peaks. Paper mills and foundries
in the Green Bay and Appleton
metropolitan areas are some of the
largest electricity users in the zone.
Electric load is forecasted to grow
at approximately 0.4 percent
annually through 2024. Also,
locally generated electricity is
declining in the area with smaller,
coal-fired generators most at risk.
This includes generation owned
by industries, municipalities and
utilities.

limitations in Zone 5
Transmission system performance
issues in Zone 5 are generally
related to heavy market flows from
and to the south, resulting in high
345-kV and 138-kV line loadings
and the need to monitor potential
multiple contingency conditions.
While not specifically identified in
the project list for this assessment,
ATC’s capital forecast includes the
cost of a preliminary alternative
Electric System Overview
Increases expected in
population, employment
Population in Zone 5 is projected to
grow 0.6 percent annually between
now and 2023, and employment
is projected to grow 1.1 percent in
the same time period. Waukesha
County is projected to realize the
largest increase in both population
and employment.
Electricity usage
Peak electric demand typically
occurs during the summer
months. Large industrial loads in
the Milwaukee metropolitan area,
including Charter Steel and Miller
Brewing, are among the largest
electricity users in the zone.
Electric load is forecasted to grow
approximately 0.8 percent annually
through 2024.

10 -Year Transmission System Assessment
ATC delivers power in Zone 5
with various transmission facilities
including:
needed to address additional
constraints identified in the
southeast portion of ATC’s system.
Potentially, the scope of this project
might include additional connections
between existing transmission lines
in this part of the system.
