Trent Mesa WTG #79 data

Jim,

Attached is our report for WTG 79 which answers the questions posed by
Eickoff. Please note that we provided more information than we were asked
for in anticipation of additional questions from them, yourself and
engineering. In the attached report we have provided graphs which cover the
previous month (versus the previous week), the production since commissioning
(through February), and a fault list.

The gaps in the data occur wherever the SCADA system did not record data or
it was corrupted in some way. Please note the fault data is particularly
susceptible to data integrity problems but it does appear that we had pretty
good data recovery during this period.

In the graph section we included a graph of Gen rpm/rotor rpm which should
yield the gearbox gear ratio (a constant). However, interestingly enough the
values fluctuated from time to time which we cannot explain.

We will have Trent Mesa WTG #30 for you tomorrow morning.

Best Regards,
Hollis
