NREL Eastern Wind Integration Transmission Study Data
• 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.
