Vestas Availability 2002

Ilan,

Here is our first attempt at a "Vestas Availability" calculation. We did
this for the US 1.5 fleet for each month in the year 2002.

There are some things you should be aware of in this calculation:

1. The Trent leaning towers are not excluded in these numbers. We are
working on excluding these towers but that is complicated so we won't have it
completed today but you can expect it tomorrow.
2. The Vestas availability number includes a portion of the repair time in
"operational" time while the remainder is not included in the operational
time. We tried to emulate that by inserting a factor along with the VisuPro
RT term. This factor is very soft and can be changed although currently we
have it set as .5.

Please take a look at the results and let me know if you have any questions
or comments.

Thanks,
Hollis

Hollis,

Almost always VA<EA (though not always). I have not put in any kind of note
about leaving out turbines that had resets.
