What is Planning?
Identification of future infrastructure needs: 1. Serve the expected load reliably2. Meet public policy directives3. Minimize cost and environmental impact
Transmission planning – identify future transmission capacity needs given a future set of loads and resources
3
Reliability and Economic Planning
System Reliability can be characterized as maintaining energy supply to load while responding in a predictable fashion to both planned and unplanned outages in generation and transmission.
System Congestion is a measure of the economic performance which answers the question “while operating within the bounds of reliable operation, how well does the transmission system perform to deliver the lowest cost energy (or energy source of choice) to consumers?”

●TEPPC’s analyses and studies focus on studies with Interconnection-wide implications
Reliability, Cost, Emissions
●TEPPC’s role does not include Detailed project-specific studiesAdvocating projectsIdentifying potential “winners” and “losers” Siting and cost allocation
●Provides governance over the RTEP (Regional Transmission Expansion Project) process
