3.5 Energy Generation
The figures in Section 3.5 illustrate the effects of the operational strategies on
energy generation at Glen Canyon and Hoover. Although 1050 ft is the nominal
minimum power pool at Mead, there is no operating experience for the Hoover
powerplant in its current configuration (after uprating and rewinds) at low
reservoir conditions.
CRSS -Lite does not perform energy computations at this point. Model output
must be transferred from CRSS -Lite to an energy model created from CRSS to
obtain power generation data. The algorithm in CRSS that computes the power
generated at Hoover allows generation at elevations below 1050 ft. According to
the algorithm, power is generated as long as the minimum operating head of 360
ft is available, corresponding to an elevation of about 1011 ft. It is critical then to
view these results in a relative manner and not a strict numeric sense.
