Advantage factors for the nuclear
alternative, .coal-fired alternative and
combustion turbine alternative were
added to the at-market power values
in the amounts of 24 percent, 22
percent and 14 percent, respectively.
These power values are based on depend-
able capacity as defined in the Water
Resouces Council's Report - "Implement-
ing Procedures for Evaluating Hydro
Power Benefits" dated December 1981,
chapter six. The dependable capacity
may reflect a credit for intermittent
capacity. For run-of-river hydro-
electric plants, it will be equal to the
average capacity available durin~ the area
peak load period. For peaking type hydro-
electric plants, the dependable capacity
may be determined by the average capacity
available during daily peak load hours
of the area peak lead season. A proposed
hydro plant shaul d not be credited with
dependable capacity value unless a need
for the capacity and its availability on
the area load has been established.

The desi~n ac voltages of substations
and transmission lines were based on the
existing and planned ac voltages of lines
and substations in the study area. The
estimated investment Gosts for the-ac
facilities were based on costs obtained
from the "Hydro-Electric Power Evaluation"
manual. The Handy Whitman Index updated
to January 1982 was used to compute these
costs.

The FWRO's computerized alternative
power value evaluation program was used
to calculate at-market capacity values and
energy values. This program follows the
power value computation routine as contained
in the "Hydro-Electric Power Evaluation"
manual.
