Based on measurements at multiple heights and in which the
highest anemometer is close to planned hub height, and not
based on lower height measurements
Nonbankable resource estimate is a preliminary assessment of
wind conditions normally used during prospecting for wind sites. It is
normally the first stage of resource estimation when not all the uncer-
tainties in wind conditions are completely understood or completely
quantified and, therefore, the return on investment has a high degree
of uncertainty. Nonbankable resource estimates may be sufficient for
self-financed small and micro wind projects.
