Reliability (Capacity) vs. Economic Transmission
Expansion

• Transmission planning to date has been focused on
  meeting National Electric Reliability Corp.
  reliability standards. Deterministic criteria
  based on the loss of lines and resources (
  generators).
• Minimum capital for transmission
• Not necessarily the minimum cost to the customer
• Energy markets added constraints that allow
  mainly gas generation to provide reliable service
  by relieving constraints by locating in higher
  priced areas
• Wind energy and other types of generation
  generally need transmission to gain access to
  higher priced areas and be able to compete.
