compared with the previous four years' performance, and on a reliability
reporting area basis compared with the previous four years' performance.

applied; interruption causes; and SAIDI, SAIFI, and CAIDI impacts to customers
for the Event on both a reliability reporting area basis and a system-wide
basis.
(d) A listing of the TMED
values that will be used for each reliability reporting area for the
