CLfvc =
center control line value for the Forced Outage(IMS) frequencies for each of the Transmission Line Circuits in the Voltage Class for Y years prior to the ISO
Operations Date, or the date a TO becomes a PTO.
Y =
number of years prior to the ISO Operations Date (or the date a TO becomes a PTO) for which the PTO has reliable, continuously recorded Outage(IMS) data. Y=10
is preferred.
