2 Economics, public policy increasingly influence transmission planning Mandatory reliability standards, renewable portfolio requirements affect plans While reliably meeting the needs of electricity customers is the top priority for any transmission owner, market economics and public policy initiatives are playing a major role in how utilities plan for their system needs. raditionally, transmission owners performed planning studies and analysis for their individual needs; today, however, while local reliability remains the responsibility of the owner, the trend is toward broader-based planning driven by regional transmission organizations, government agencies and electricity market economics. Changing the way transmission system costs are allocated also affects the planning as well as permitting for system improvements. Regional planning initiatives increasingly focus on projects that provide additional benefits beyond local-area reliability. hese multi-benefit, or Multi-Value Projects (as defined by Midwest Independent System Operator, Inc.), also include economic savings and the ability to move renewable energy from where it is generated to where it can be used. As these projects are identified, regulators from multiple states will need to work together to determine cost sharing as well as permitting. We are working diligently with all stakeholders to design an incremental regional build-out of these projects to move forward efficiently and cost-effectively. Enforceable, mandatory reliability standards, developed by the North American Electric Reliability Corp. and approved by the Federal Energy Regulatory Commission in 2007, also play a role in how we plan, operate and maintain our system. Earlier this year, NERC issued a set of high-priority reliability issues to help the industry focus on standards setting, compliance, training and education. Several of those priorities, including a changing resource mix and the integration of new technologies, will impact the way we plan and operate our system. Our planning process also is affected by pending Environmental Protection Agency regulations for electric generators and the recently issued FERC Order 1000 governing regional planning, public policy requirements and cost allocation. he 2011 Assessment covers the years 2011 through 2020 and indicates a need for $3.8 to $4.4 billion in transmission system improvements. he total includes $1.0 billion in specific network projects, $1.0 billion in asset maintenance, $0.7 billion in multi-benefits projects, and this year a range of $1.1 to $1.7 billion in other capital categories. Other capital categories can include developing or unspecified network projects, interconnection projects and infrastructure relocation. Cost estimate of system improvements otal 10-Year Capital Cost $2.8B $2.7B $2.5B $3.4B $3.8/ $4.4B ransmission is the vital link in bringing power to communities ransmission 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

3 North Central Wisconsin Zone 1 Electric System Overview Slight increases expected in population, employment Population in Zone 1 is projected to grow at 0.6 percent annually between now and Employment is projected to grow at 0.9 percent annually between now and Marathon County will realize the largest increase in population and employment, while Adams County will have the highest growth rate. Electricity usage growing Peak electric demand typically occurs during the summer months, with some winter peaks appearing in the northern portion. Primary electricity users in Zone 1 include a number of large paper mills and food processing plants. Electric load is projected to grow approximately 0.66 percent annually through Helping to keep the lights on, businesses running and communities strong 2011 AC 10-Year Assessment 3

4 System Limitations North Central Wisconsin Zone 1 ransmission system characteristics in Zone 1 AC delivers power in Zone 1 with various transmission facilities including: East-west 345-kV line from Arpin Substation through Stevens Point extending to the Appleton area, 345-kV line extending from Wausau to northeastern Minnesota, 345-kV line extending from Wausau to Stevens Point to eastern Outagamie County (Highway 22), 115-kV network in the northern portion of the zone, and 138-kV and 69-kV network in the southern portion of the zone. here are a number of transmission system performance issues in Zone 1 including overloaded lines and equipment and low system voltages. ransmission system limitations in Zone 1 Key system performance issues in Zone 1 include low voltages and thermal overloads in the southern portion of the zone. hese issues will necessitate a combination of reinforcements. Zone 1 includes the counties of: Adams Marathon Forest (southwestern portion) Fond du Lac (northwest portion) Green Lake Juneau Langlade Lincoln Marquette Monroe (eastern portion) Oneida Shawano (western portion) Vernon (eastern portion) Vilas (southern portion) Waushara Winnebago (western portion) Wood 4
