Emergency Loads. Review the overall emergency requirements for the
area, based on criteria for the facility or as furnished by the using agency,
to determine the following:
a) The emergency loads that may be combined in groups to take
advantage of the coincidence factor.
b) The type of distribution system needed for reliability and to
economically satisfy at least the less critical emergency load requirements.
This reliability can be provided only if the source of electric power is not
the determining factor.
c) Area loads that must be added to individual emergency loads;
for example, security lighting and minimum roadway lighting.
Expansion. The planned development of the area, as shown on the
activity general development map, shall be considered for requirements of
Activity Loads. Activity loads are loads that consist of two or
more area loads served from a single electric power source and an integrated
General Loads. Follow the approach used in para. 2.3 for area
loads. Area loads used for determining activity coincidence demand should be
the area coincident demand exclusive of allowance for load growth.
Coincidence Factor. Refer to para. 2.3.2 for the necessary
approach. Where dissimilar areas, whether residential, administrative, or
industrial, are part of an activity, make a careful analysis of the
coincidence factor used.
Load Growth. As for an area, components should be sized after due
consideration has been given to load growth. Apply this increase to the
coincident demand of the activity.
Expansion. The planned development of the activity, as shown on
its general development map, shall be considered for requirements of future
