D. TRANSMISSION DIVISION

The Transmission Division provides facilities for the delivery
of Colorado River Storage Project power to major load centers or
to delivery points from which other agencies may transmit the
power to load centers and to interconnect the generating plants of
the Colorado River Storage Project with each other and with ad-
jacent Federal, public. and private utility transmission systems.

Construction Activities

Construction of the CRSP backbone transmission system with
associated communications and control facilities is essentially com-
plete. The remaining connecting link to Eastern Colorado, the Poncha
(Salida) -Midway section of the Curecanti-Midway 230-kv line is
now under construction and completion is expected by August 1968.
The Midway terminal substation will also be completed by that
time. The 345-kv switching station, being constructed near Flagstaff,
Arizona, is nearing completion and should be ready for operation
by December 1966. The original plan of the CRSP backbone system
included a 230-kv switching station near Rifle, Colorado. Specifica-
tions for that substation are now being prepared and construction is
expected to start early in 1967.

Construction of the Hayden-Archer 157-mile, 230-kv transmis-
sion line and Archer substation was completed and the line and
substation energized on January 19, 1966.

Contract for construction of the Poncha-Midway 230-kv trans-
mission line was awarded by the Bureau on February 8, 1966.
ApprOXimately 38 percent of the work was finished at the end of the
report year. Preliminary designs of the Midway substation have
been initiated.

Power Marketing

With the beginning of the 1965-66 winter season, contracts for
the sale of Storage Project power were supplemented to increase
and extend 1966-67 contract rates of delivery to equal estimated
]970-71 power requirements. Power is being marketed in Regions
,3, 4, 5, and 7 of the Bureau of Reclamation which includes the States
()f Colorado, Utah, Wyoming, New Mexico, Arizona, and parts of
California and Nevada. At the end of the 1966 summer season a
totnl of 88 customers including nonpreference customers were under
~on tract. Preference customer contracts generally guarantee that the
. torage Project will supply the 1970-71 contract rates of delivery for
