9.7 Advantages and Disadvantages of Technology
A discussion of each of the qualitative screening criteria is provided in this
section.
9.7.1 Fit to KIUC Needs
Although wind cannot provide firm capacity, KIUC interest for reduced fuel
consumption is well met by wind power as shown by the savings demonstrated in Table
9-5 KIUC has sufficient generation to cover all current loads and flexible generation
such that it can compensate for the intermittency of wind power, at least at small elvels of
penetration. In the long term, KIUC would do well to consider project sites with wind
profiles that match load profiles to maximize effective penetration of wind. One such
