Description: This feature class/shapefile represents electric power Independent System Operators. Independent System Operators were set up by the Federal Energy Regulatory Commission (FERC) to provide non-discriminatory access to power and to more adequately administer the transmission grid on a regional basis throughout North America. The following updates have been made since the previous release: updated attribution using best available sources.
