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

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
