WEAF

Hawaiian Electric, Hawaii Electric Light and Maui Electric all use the following formula to calculate WEAF:

Weighted Equivalent Availability Factor - WEAF
WEAF = [(AH - EUDH - EPDH - ESEDH) x NMC]	x 100%
(PH x NMC)

WEAF = [(AH - EFDH - EMDH - EPDH - ESEDH) x NMC]	x 100%
(PH x NMC)

See NERC GADS Appendix F for a definition of each parameter.
