Generator Facility Rating Methodology

The purpose of this procedure is to document the methodologies used by FPL (generator owner) in rating its generator facilities to meet the requirements of NERC Standards FAC-008-1, FAC-009-1.   This procedure is applicable to fossil, solar photovoltaic and nuclear generator Facilities.

TERMINOLOGY

Bulk Electric System (BES): As defined by the NERC Regional Reliability Organization (RRO), the electrical generation resources, transmission lines, interconnections with neighboring systems, and associated equipment, generally operated at voltages of 100 kV or higher. Radial transmission facilities serving only load with one transmission source are generally not included in this definition.

Equipment Rating: The maximum and minimum voltage, current, frequency, real and reactive power flows on individual equipment under steady state, short-circuit and transient conditions, as permitted or assigned by the equipment owner.

Emergency Rating: The rating as defined by the equipment owner...
