American Transmission Co. was formed in 2001 to plan, permit, build, own, operate and maintain a high-voltage electric grid that meets the reliability and economic needs of our customers. Our planners continually conduct engineering studies on the electric transmission system, looking for potential problems that may affect future performance. Our studies identify and prioritize future projects needed to improve the adequacy and reliability of the system and meet evolving public priorities.

After nearly 10 full years of operation and $2.2 billion in new and upgraded infrastructure investment, electric system reliability remains our top priority. But looking forward, we see an increasing need for an expanded regional transmission system. Consequently, our planning focus has broadened to consider projects that provide economic and public policy benefits as well. Several factors, including the emerging wholesale market and federal and state policy, play a larger role in our planning process today than they did when we first began operation in 2001.

The majority of the grid’s regional interconnections were made in the late 1950s through the early 1970s to accommodate local reliability needs. Nationally, the transmission system was not designed to accommodate the expanded energy flows required by the current wholesale marketplace.

Renewable portfolio standards also call for a more robust regional grid to move power from wind-rich areas west of Wisconsin to population centers where the electricity is consumed. The changed marketplace and increasing importance of renewable energy sources necessitate a broader view of the system, which influences planning policies and studies.

Since our inception, load growth and operational issues were the primary drivers for transmission improvements, and planning studies were conducted accordingly. Today, finding a way to build the system to allow states to meet their renewable energy standards and getting the full benefit of the Midwest ISO market for ATC customers have become more significant transmission needs. We continue to collaborate with customers and other stakeholders to plan best-value projects that meet system needs and provide multiple benefits.

The 2010 Assessment covers the years 2010 to 2019, and for the second year, we have included asset renewal projects through the full 10-year horizon. Our studies indicate $3.4 billion in necessary transmission system improvements. The total includes $1.0 billion for transmission network upgrades, $0.7 billion for regional multi-value projects, along with $1.7 billion in interconnection and asset renewal projects, infrastructure replacement and relocation, and other smaller network reliability improvements.

Electric System Overviewincreases expected in population, employmentPopulation in Zone 3 is projected to grow about 1.1 percent annually between now and 2020, 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.

higher-than-average demand anticipatedElectric load is expected to grow approximately 2.2 percent annually through 2019 for all of Zone 3.

Transmission is the vital link in bringing power to communitiesTransmission lines move electricity at high voltages over long distances – from power plants to communities

where local utilities deliver power to homes and businesses via distribution lines. A reliable transmission network

provides access to many sources of power, whether they are local or regional. having multiple paths to get power

from producers to consumers lessens the chance that they will experience service interruptions. with an increasing

emphasis on renewable energy, transmission system planning will become even more important to put the power

of wind on the wires.

Transmission system characteristics in Zone 3ATC delivers power in Zone 3 with various transmission facilities including:

n Columbia-North Madison 345-kV lines,

n Columbia-Rockdale 345-kV line,

n Paddock-Rockdale 345-kV line (in-service spring 2010),

n Paddock-Wempletown 345-kV line,

n Rockdale-Wempletown 345-kV line, and

n 138-kV facilities from the Nelson Dewey Power Plant, around the Madison area, and in the northwest and southeast portions of Zone 3.

There are a number of transmission system performance issues in Zone 3 including voltage instability, limited import capability, overloaded lines and equipment, and low system voltages throughout the zone. The causes of these emerging issues include steady growth in certain areas, import capability from Illinois, new power plants and different generation dispatch scenarios.

Transmission system limitations in Zone 3In our analysis of Zone 3, we identified low voltages and transmission facility overloads. Low voltages are particularly serious in the Spring Green, Jefferson, Milton and Brodhead areas. Many overloads on 138-kV and 69-kV facilities through Zone 3 are emerging concerns.

We have implemented seven projects in Zone 3 since the 2009 Assessment, most notably the construction of the Paddock-Rockdale 345-kV line.

Our current plans in Zone 3 include 45 system reliability and economic projects between 2010 and 2024. These projects are in various stages of development. The most notable planned, proposed, provisional and asset renewal projects in Zone 3, along with their projected year of completion and the factors driving the need for the projects, are listed below.
