The
Origin
of
the
Name
of
the
US
Power
Grid The
US
power
grid
is
a
complex
network
that
delivers
electricity
from
power
plants
to
homes
and
businesses
across
the
country.
Its
name,
the
power
grid,
comes
from
the
physical
infrastructure
that
makes
up
the
system:
a
network
of
power
lines
and
transformers
that
connect
power
generation
facilities
to
the
end-users. The
system
was
first
developed
in
the
early
1900s
by
several
small
cities
and
towns
that
were
seeking
to
generate
and
distribute
electricity
locally.
The
first
power
plants
were
typically
small
and
powered
by
coal
or
water,
and
the
power
lines
were
strung
up
on
poles
or
buried
underground.
Over
time,
these
local
power
systems
began
to
merge,
creating
a
nationwide
network
that
we
now
know
as
the
US
power
grid. The
name
"power
grid"
was
first
used
in
the
1920s
to
describe
the
interconnected
power
systems
that
were
developing
throughout
the
country.
It
became
a
familiar
term
among
engineers
and
electricians,
and
eventually
became
the
standard
name
for
the
entire
power
system. Today,
the
US
power
grid
is
one
of
the
largest
and
most
complex
systems
in
the
world.
It
is
comprised
of
thousands
of
miles
of
power
lines
and
millions
of
transformers,
and
it
connects
over
9,000
power
plants
to
nearly
145
million
customers.
Despite
its
size
and
complexity,
the
power
grid
remains
an
essential
part
of
modern
society,
providing
the
electricity
that
powers

businesses,
and
industries. In
conclusion,
the
name
"power
grid"
for
the
US
power
system
is
derived
from
the
physical
infrastructure
that
makes
up
the
network.
Its
development
began
with
small
local
power
systems
and
gradually
merged
into
a
national
network
that
plays
a
vital
role
in
modern
society.
