1 March 26, 2014 Transmission Coordination and Planning Committee 2014 Q1 Stakeholder Meeting

2 Introductions Background Transmission Planning Process 2014 TCPC Study Scope Stakeholder Input and Questions Agenda 3/26/2014 2

3 Energy Delivery /26/2014

4 Meeting Objectives Plan the expansion of the transmission system to ensure reliable, efficient delivery of energy to customers at a reasonable cost. Develop and coordinate plans with interested stakeholders at the local, state, and regional level to identify and address concerns in the early stages of project development. Ensure openness and transparency while addressing applicable regulatory requirements. 4 3/26/2014

5 Transmission Planning 5 3/26/2014

6 What is Transmission Planning? The process of evaluating the transmission system to identify transmission facilities required to deliver existing and future generating resources to existing and future customer loads while balancing reliability, societal impact and cost. 3/26/2014 6

7 Types of Planning Studies System Interconnection Requests o Generator, Load or Transmission Interconnection Feasibility Study System Impact Study Facilities Study Transmission Service Study Reliability Study Economic Study 7 3/26/2014

8 Transmission Planning Process Major factors in the process: Future planning periods (5, 10, 20+ years) Load forecasts (existing + future growth scenarios) Generation output (serve local load vs. off-system sales) Generation types (thermal, hydro, wind, solar, etc.) Planned projects (local and regional) System disturbances (consider all relevant outages) Reliability criteria (the measuring stick for adequate transmission system performance) Transmission system commitments (capacity availability) Local, state, and federal regulatory requirements 8 3/26/2014
