for use of CRSP facilities, less the estimated revenue for wheeling power
for Ute and SRP. The 3-year average annual transmission capacity
commitments were 1,580.7 MW, which consisted of 1,195.4 MW for the installed,
capacity of the CRSP plants and 385.3 MW for Ute and SRP. Dividing the
average annual cost of $10,453,000 by the capacity of 1,580,700 kW resulted
in a unit cost of $6.61 which was rounded to $6.60 per kW-year for the
established firm transmission rate. The nonfirm transmission rate of 1 mill
per kWh was not revised.

V. PROPOSED TRANSMISSION RATES
Based on data available as of the end of FY 1981, projections were
made, as shown on Table 1, for the three ensuing years of FY 1982, 1983, and
1984 as to the anticipated transmission system investment and OM&R costs;
costs of wheeling over other systems; revenues for rental of CRSP
transmission facilities; and revenues from Ute and SRP because of the
exchange of Ute and SRP coal-fired generationifor CRSP hydro generation.
Table 1 also shows the estimated transmission!capacity commitments and the
annual cost per kW for each of the three futu~e years FY 1982, 1983, and
1984. The average cost per kW for the three jears, $10.27 per kW-year, is
proposed as tne firm transmission rate. A new non-firm transmission rate of
2 mi 11 s per kWh is also proposed. Two mill s per kWh is the energy rate
obtained by applying an annual load factor of 58.2 percent to the firm
transmission rate of $10.27 per kilowatt year. Both rates should become
effective April 1, 1983, or as soon thereafter as possible, where existing
contracts do not permit changes by then. A special nonfirm transmission
rate of 1 mi 11 /hWh for the return of emergency ass i stance is under
consideration.

The annual replacement cost shown for each year on Table 1 is the
average of the estimated CRSP transmission replacements for the FY 1982-2090
period, rather than the replacements which are actually anticipated in the
next 3 years. This average method appears more appropriate, since the
prOjections for the next 3 years include extraordinarily high costs due to
the replacement of the CRSP supervisory control and data acquisition (SCADA)
system. \

Figure 2 shows the historical and proposed firm and non-firm
transmission rates.

VI. HISTORY OF FIRM POWER RATES
The first CRSP firm power rate, the R4-Fl schedule, was established on
March 6, 1962. The charges were:

3 mills per kWh for energy and
$1.275 per kW/Month for capacity.

Under the 1962 marketing criteria, custdmers with no supplemental
supply were permitted to receive their total energy requirements. Customers
with a supplemental supply were permitted to take up to 70 percent seasonal
load factor energy through March 1976. The average rate at 58.2 percent
, seasona 1 load factor was 6 mi 11 s per kWh.
