WEFORd

The calculation of WEFORd is as follows:

Weighted Equivalent Forced Outage Rate demand - WEFORd
WEFORd = [(FOHd + EFDHd) x NMC]	x 100%
[(SH + FOHd) x NMC]

where

FOHd = f x FOH

EFDHd = (EFDH - EFDHRS) if reserve shutdown events reported, or

= (fp x EFDH) if no reserve shutdown events reported - an approximation.

fp = (SH/AH)

r=Average Forced outage deration=(FOH)/(# of FO occurrences)
D=Average demand time=(SH)/(# of unite actual starts)
T=Average reserve shutdown time=(RSH)/(# of unite attempted starts)

See NERC GADS Appendix F for a definition of each parameter. The Hawaiian Electric Companies follow the methodology described in Note 1, Method (II) of Appendix F.
