About the NATF
The North American Transmission Forum (NATF) is built on the principle that the open and candid exchange of information among its members is the key to improving the reliability of the transmission systems in the U.S. and Canada.

Proper modeling of external systems is key to providing system operators with situational awareness of both their own and adjacent systems. External modeling also informs operators how changes on adjacent systems can impact their systems.
NATF members recently developed the “NATF EMS External Modeling Reference Document” to provide guidance to those working to improve performance of their EMS external models. The intended audience is personnel responsible for developing and maintaining EMS models for real-time state estimator and real-time contingency analysis.We believe sharing this document with the industry will enhance external system modeling for all system operators, thus enhancing reliable operations for the entire Bulk Electric System. Accordingly, the NATF has posted the document to the Documents section of its public website (www.natf.net).
