Notes: • NERC region and reliability assessment area maps are provided on EIA's Electricity Reliability web page: http://www.eia.gov/cneaf/electricity/page/eia411/eia411.html • Circuit miles do not equal physical miles on the ground; the reference terminology for that concept is structural mile. • Some structures were designed and then built to carry future transmission circuits in order to handle expected growth in new capability requirements. • Lines are taken out of service for a variety of reasons including intentional changes to the right-of-way to better useavailable land for different levels of voltage and types of poles and towers.
