This report is the response to NERC’s Strategic Initiative on ATC and defines ATC and related terms. From a commercial perspective. ATC represents the capacity left on a transmission line after existing power transfers have been accounted for. It’s the measure that grid operators use to ensure that additional electricity can flow without risking grid stability.
