10
c.

forecasted
weather
conditions.
14
d.
“Grid-enhancing
technology”
means
hardware

software
15

24
f.
“Reconductored
with
an
advanced
conductor”
means
replacing
25
the
existing
electric
conductor
with
a
conductor
that
has
a
26
direct
current
electrical
resistance
not
less
than
ten
percent
27
lower
than
existing
conductors
of
a
similar
diameter
on
the
28
system
and
may
include
rebuilding
support
structures
or
other
29
associated
facilities.
30
g.
“Thermal
limit”
means
the
temperature
an
electric
31
transmission
line
reaches
when
heat
from
the
electric
current
32
flow
within
the
electric
transmission
line
causes
excessive
33
sagging
of
the
electric
transmission
line.
34
h.
“Topology
optimization”
means
a
software
technology

advanced
10
conductor
to
achieve
one
or
more
of
the
purposes
listed
in
11
paragraph
“c”
.
12
b.
The
study
