1. ATC Planning Zone Meeting Teresa Mogensen Director, Transmission Planning & Service Scott Barnhart Manager, Transmission Planning

2. Welcome and Introductions Your name and affiliation Please state your name and affiliation each time you offer input during today’s discussion

3. Overview of ATC Began operations on January 1, 2001 A transmission-only public utility company with transmission assets in Wisconsin, Michigan and Illinois Offices in Waukesha, Cottage Grove and Green Bay, Wis.; Kingsford, Mich.; and Washington D.C. Owns, plans, constructs, maintains, and operates electric transmission equipment Provides electric transmission service to utilities and other wholesale power buyers Jointly owned by electric cooperatives, investor-owned utilities, municipal utilities, and other public power entities Regulated by Federal Energy Regulatory Commission for rates and tariffs Regulated by states for siting

4. Goals for this Meeting Familiarize you with ATC and the transmission planning process Discuss identified system needs and possible solutions in this region Solicit your ongoing participation in, and shaping of, the planning process Solicit your input in helping identify and refine feasible options to address needs

5. ATC Transmission Planning Philosophies Adequate Infrastructure –To support load growth and system utilization Reliable Service Interconnection –Generators, loads, and other transmission systems Access –To a competitive energy market Collaboration Timeliness of project efforts

6. ATC Planning Bases Individual Load/Generator Zone ATC System Wide US Regional/National Consolidate resolution of needs into cohesive overall plan

7. Process to Date – Ten Year Transmission System Assessment Covers years 2001-2010 Identifies needs, limitations, and violations of planning criteria Lists solutions to certain needs, limitations, and violations –Projects within existing substations –Projects within existing right-of-way –Near term transmission projects Other solutions to be defined after public discussion Initial assessment published June 1, 2001

8. Process to Date-Ten Year Assessment Logistics Developed system performance criteria Developed logical “planning zones” –Facilitates development of projects that serve multiple purposes and resolve multiple issues –Umbrella plans – phased approaches to needs resolution –Allows for more focused public discussions Evaluated peak system usage scenarios Included proposed new generation that had been announced or for which applications had been filed

9. ATC Planning Zones

10. Process to Date – June 8 Introduction Introduced public planning process concepts –Identification and discussion of needs and possible solutions –Importance of your input –Evolutionary process –Iterative process (Needs, Assessment, Input, Analysis, Plan Design, Input) - Repeat –Desire for coordination with you and your processes –Commitments to treat affected landowners fairly and to mitigate the environmental impact of construction, maintenance, and operation activities Introduced and offered initial report for your review Announced upcoming Planning Zone Meetings for more focused discussion

11. Transmission Network Concepts Transmission lines are the highways and interstates of the electric system Transmission system connects power plants to electric distribution systems Distribution systems serve the customers – the cul-de-sacs of the electric system Transmission systems – high voltage – 69,000 volt to 345,000 volt Distribution systems – lower voltage – 46,000 volt down to 120 volt

12. Transmission Network Concepts, continued Distribution systems are typically “radial” systems – loss of a distribution line results in interruption of service to customers Transmission systems are networks – designed so that loss of a transmission line results in no interruption of service to customers Extensive transmission system failures can cause widespread interruption of service

13. Overview and Discussion of Zone Needs Performance Criteria Violations and Other Needs

14. Overview and Discussion of Potential Solutions Proposed Additions

15. Your Regional Plans and Concerns Given what you have heard so far, –General comments and thoughts? –Potential impacts on you? –Your area plans which may be affected? Also, in your area, –What infrastructure planning processes are underway now? –Any current efforts to coordinate your overall infrastructure plans? –Thoughts on most suitable general locations for transmission infrastructure? –What is coming up that we should know about? –What are key issues in this region that we should be aware of? –Any timing coordination issues to consider?

16. Lunch 12:30 – 1:00

17. Focus on Possible Solutions

18. Planned System Additions Upgrading Existing Transmission Lines –Plains-Stiles –Hiawatha-Indian Lake

19. Planned System Additions Various New Distribution Substations

20. Planned System Additions Equipment Additions at Existing Substations: –New transformers at Munising and Straits –Phase shifting transformers at Straits –Current transformer at Cedar –Capacitor banks at Bruce Crossing, Thunder, Dunn Road, Wesmark, Lincoln, Manistique, Detour, St. Ignace & Louis Paper

21. Potential New Right of Way Needs Hiawatha-Indian Lake Indian Lake-Straits West Marinette-Chandler Presque Isle or Dead River - Marquette

22. Moving Ahead What are the best ways to continue to coordinate and work with you? Who else should we be coordinating with? What else would you like to see from us?

23. To Watch For Planning Zone Meetings in July and August Updated Ten Year Assessment in October Planning Zone Meetings in November and December Additional meetings and information as announced
