Subject: Trent Mesa Report Elements from Oct 2001 to Dec 2001

Executive Summary
The following report incorporates the monthly meter readings by the site
personnel & review of the mon files from Visupro. In all three months the
project availability ramp up was not attained although the Dec availability
is close. It should be noted that the Oct 2001 grid availability was
extremely poor and that erratic grid conditions are known to cause turbine
trips associated with grid variations. This should be less of a problem due
to the DVAR but the problem may not be eliminated entirely. In November
2001 the Visupro data recovery was only about 85% and it is possible that
there was higher availability but there is no recorded data to prove it. In
contrast the data recovery was over 94% in Dec 2001.
