generation at Glen Canyon Dam is very high over a wide
range of powerplant output. The facility can be run at
very low and very high output, and output can be
increased and decreased rapidly without significantly
increasing the costs of electrical generation, making
it very competitive with other sources of peaking
power. The value of the power, and hence the at-
tractiveness of long-term contracts, is increased by
scheduling power generation to coincide with peak de-
mand. Producing power in this fashion enables WAPA to
sell the greatest amount of power at firm energy rates,
as stipulated in the CRSP Act.

Figure V-3. When operating in a "peaking power" mode,
dam releases increase during periods of high demand
(morning and evening).
