ABSTRACT
NERC revised the earlier reference documents on transfer capability published in 1980 to provide additional clarifi cations and examples. The revised document [2] addresses transmission transfer capability from the perspective of the transmission systems physical characteristics and limitations. It provides the technical basis for discussions about transfer capability. Background information on industry practices related to transfer capability is also presented including defi nitions, concepts, technical issues, and simulation techniques used to calculate and report transmission transfer capability. The report also recommends two transfer capability measures: First Contingency Incremental Transfer Capability (FCITC) and First Contingency Total Transfer Capability (FCTTC). The FCITC is defi ned as the amount of electric power, incremental above normal base power transfers that can be transferred over the interconnected transmission systems in a reliable manner. The FCTTC is defi ned as the total amount of electric power (normal base power transfers plus FCITC) that can be transferred between two areas of the interconnected transmission systems.
