Product Delivery

For this proposal, several basic assumptions have been made to define the
transmi ss i on system necess ary to carry power generated by Diamond Fork.
The system would also be capable of delivering pumping energy for operation
of the Fifth Water Pumped Storage Powerpl ant.

Equivalent or designated Federal Points of Del ivery (FPOD's) would be
established as a result of detailed transmission system analysis and other
transmission considerations which ultimately depend' on project par-
ticipants.

Loads were assumed to be as follows;

_ 440 MW to preference customers in the Northern Division of the
CRSP marketing area delivered over the CRSP transmission system.

- 100 MW delivered at Flaming Gorge Switchyard.

- 200 MW delivered at Sheep Creek Substation.

400 MW delivered to entities in Arizona, California, and Nevada.

.A-

Additional transmission required for this assumed load distribution
is shown schematically in Figure 4. The new transmission includes: 7'f

1. 46 kV and 345 kV transmission lines between the Fifth Water
Switchyard and the powerplants and switchyard facilities
to terminate these lines.

2. A 345 kV transmission line between Sheep Creek and Bonanza
Substations with terminating facilities.

3.

A 345 kV transmission 1 ine from Sheep Creek Substation to SigUrd)
Substation, thence to Glen _ anyon Switchyard, thence to the Navajo
S~itchyard, along with substation facilities to terminate these
llnes. ' '

4. A 345 kV transmission line between Sheep Creek Substation and
Springville Substation, along with substation facilities to ter-
minate this line.

5. A 46 kV transmission line from the Diamond Fork Switchyard to tie
into an existing 46 kV transmission line.

Delivery of power beyond equivalent or designated FPOD's will be addressed
and would define Western's and Reclamation's responsibilities in the
delivery of electric service. As a general practice, all costs, including
losses for del ivery of service beyond the specified contract FPOD's would
be the responsibility of the participant. However, alternatives could be
considered to provide for third-party wheeling or assistance in the con-
struction of required transmission facilities. Arrangements will also be
considered in which participants provide their own pumping energy or where
it is provided for in their behalf by other sources.
