assumed that the generating reserves would equal 10 percent of the
load and that transmission losses would be offset by diversity.

The capacities shown for project irrigation pumping are average
monthly peaks, based on the assumption that there will be a special
rate for such loads which will not have a seasonal contract rate of
delivery, but will have a demand charge based on the actual monthly
demand. In determining the capacity available for commercial use,
it has been assumed that CRSP capacity would be reserved for project
irrigation pumping up to the maximum monthly peaks, as shown on foot-
note 2 to Table 3. The reservation for irrigation pumping is expected
to increase from 1 MW in 1978 to 113 MW in 1988. As explained above
for energy, the capacity on Table 3 excludes powerplant visitor center
use, Government camp use, the Bonneville Unit pumping, and the anlount
of pumping served out of the Navajo Dam Powerplant, assuming the plant
will be in service by 1982. The project capacity is expected to
increase in 1989 due to the Central Utah Project generation. After
1989, the project capacity is expected to decrease due to upstream
water depletions by participating projects.

D. Power Revenues. The gross annual power revenues of the
CRSP, as shown on Table 1, started in fiscal year 1964 at $502,000 and
have been steadily increasing with a peak of $66,866,000 expected in
fiscal year 1989, the year in which the last generating unit (Central
Utah Project) is estimated to be placed in service. Table 4 gives the
estimated future revenues, broken down into various categories. The
data are displayed to the nearest $1,000 and consequently, some of the
arithmetical totals across or down the columns may differ slightly
from the data shown. A discussion of the categories follows.

1. Project Use. This category includes the use at the
storage unit dams and reservoirs for visitor's centers and Government
camps. For bookkeeping purposes, the annual revenues are calculated
as the metered kWh times 6 mills. The rate assumed for this is
inconsequential, inasmuch as the revenues are counterbalanced by costs
included in the annual O&M expenses. For future years, the annual
revenues and costs for project use have been estimated as $24,000.

"

2. Firm Energy. This category includes the energy
revenue component of the firm energy sold to customers and the energy
supplied for irrigation pumping on the participating projects and for
salinity control. The aforementioned uses have been lumped together in
the revenues, since the same rate applies for irrigation pumping energy
as for firm energy sales. The firm energy revenues shown on Table 4
were obtained by applying the appropriate energy rate to the sum of
the energy shown on Table 2 for project irrigation pumping and firm
sales. For the period through May 1977, the rate applied is 3 mills.
For the period of June 1977 through September 1979, the existing rate
of 3.4 mills is applied. For October 1979 and thereafter, the rate
applied is the proposed rate of 4.5 mills.
