on line in September 1967, the Morrow Point Powerplant in December 1970, and
the Crystal Powerplant in August 1978. The Fontenelle Powerplant of the
Seedskadee participating project went on line in May 1968. Following are
the projected generating capacities with planned uprating of the generators
through replacing stator windings, rotor poles and windings, and by making
other electrical and mechanical modifications as needed:

The capabilities are the maximum amounts that can be generated at each
plant with all units operating. It is estimated that the Glen Canyon
Powerplant will be uprated by FY 1987 and the Blue MesaPowerplant by FY
1988.

Transmission facilities include a high-voltage transmission grid to
deliver power to certain delivery points, to provide interconnections among
the plants of the CRSP units and participating projects, and to interconnect
with other existing Federal and utility systems. Additional transmission
facilities are .planned in order to improve system reliability, to provide
for the accommodation of inadvertent power flows from other systems, to
conserve fuel by better coordination of thermal and hydro resources, and to
allow delivery of power from the additional generation mentioned above. Map
No. 594-400-79 is attached hereto as Exhibit A to show the CRSP powerplants
and transmission facilities, as well as other existing principal power
systems in the CRSP market area.

IV. HISTORY OF TRANSMISSION RATES

The first CRSP firm transmission rate, $4.50 per kilowatt-year, was
established in October 1965. The estimated transmission costs were
$8,968,000 at that time, which were comprised of annual amortization and
OM&R costs of the planned CRSP transmission system, plus estimated costs to
the United States of wheeling over other systems in Utah. The estimated
transmission capacity commitments were 1,986.5 MW, which consisted of
