There is a very significant difference,
in some respects, in the tentative Bureau plan
and the tentative plan presented by the private
power companies. The private power companies
involved are the Public Service Company of
Colorado, the Arizona Public Service Company,
the Public Servic~ Company of New Mexico, the
Utah Light and Power Company and the Pacific
Light and Power Company. Their plan involves,
in a large part, construction of transmission
lines by these private companies. Sometime
ago we pointed out to the Board that the Utah
Light and Power Company was constructing a
230 KV line from the vicinity of Salt Lake
City south to Springville, Utah, which is
situated somewhere in here, quite a bit north
of Glen Canyon. Now the basic system evolved
by the power companies is the construction of
multiple 230 KV lines instead of one 345 KV
line. The private power companies feel that
this multiple 230 system has many advantages
over the 345 system. The tap in, for instance,
is cheaper. Just to give you an example, it
costs over a million dollars to tap in to any
of these high voltage lines and the bigger the
line, the more the cost to tap in to it. So
anybody who is expecting to tap in to his
home, who happens to be along this route, to
get storage project power, is in for a very
rude shock, because the initial large expense
of high voltage transmission is in trying to
reduce it to lower voltage.

The use of multiple 230 KV offers a great
many advantages - more facilities, less initial
costs and better operation over the long term
period. So at the present time the Utah Light
and Power is constructing a single 230 KV
line south to the southern part of Utah, and
they say, irrespective of whether or not Glen
Canyon is in existence, that the Board of
Directors of that company and the Board of
Directors of the Arizona Public Service Com-
pany have already authorized the extension of
that line to the Arizona border, at which
point the Arizona Public Service Company will
pick it up and construct a 230 KV line on into
Phoenix, Arizona. They say they are going to
do that irrespective of this project power.
They point out that this project power is
only about one-fifteenth of the total power
that will be required by these five states -
'Arizona and the four upper basin states - by
1980, and that they therefore have to provide
