Today’s LiveWire Spotlight evaluates NERC’s filing to FERC reporting on the use of non-consequential Load loss as a planned element of a single contingency event since TPL-001-4 took effect on January 1, 2015. Two surveys of the planning community identify only four PCs or TPs who used, or expects to use, the TPL-001-4 Table 1, Footnote 12 allowance.

The infrequency of Table 1, Footnote 12 exceptions suggest that planners explore all other viable options prior to its use. Still, NERC will continue to look for signs that indicate a TP or PC is taking undue advantage of the allowance.
