New
Mexico
Governor
Bill
Richardson,
a
former
US
Energy
Secretary,
is
to
announce
the
project,
proposed
by
private
developers
Tres
Amigas
LLC
at
a
news
conference
Tuesday
morning.
There
are
three
distinct
and
mostly
separate
grids
covering
the
US,
as
well
as
parts
of
Canada
and
Mexico:
The
Western
Interconnection,
which
includes
states
from
the
Rocky
Mountains
to
the
Pacific
Ocean;
The
Eastern
Interconnection,
including
the
Great
Plains
and
all
points
east;
and
the
Texas
Interconnect,
confined
to
most,
but
not
all,
of
Texas.
Connections
between
any
two
of
the
grids
are
limited…
