Dear Michael,

We, too, enjoyed the opportunity to meet with you last Thursday and 
appreciate the candid feedback you and Michael were able to give us regarding 
the PA projects.  We are currently investigating your and Mr. Winsor's issues 
regarding availability, noise, blades, electronic faults, and cold weather 
faults.  I suggest we schedule a conference call with our Operations team and 
Mr. Winsor this week to clarify and resolve any issues you may have.  We 
appreciate your business, and look forward to serving you better in the 
future.

Best regards,
Benjamin Bell

Subject: FW: GEWE reporting and follow-up



I wanted to thank all three of you for coming to meet with us this morning. 
It is very exciting to have GE in this business. I am forwarding the 
following e-mail since I thought you would want to know what the feelings 
currently are in the trenches at Zilkha in terms of the PA projects. The 
projects were commissioned six months ago so I can understand the frustration.

We look forward to seeing you at AWEA and to a long and fruitful relationship.

With best wishes,

Michael

significant data analysis.  We believe that GEWE overstates their 
availability numbers by up to 4%.  We have shared this information with GEWE

Kurt,

I have a few questions relating to the Monthly Reports prepared for the Mill 
Run and Somerset Wind Farms.  They are as follows:

* On April 5th the Main Circuit Breaker located within the pad mounted 
transformer on WTG#7 at Mill Run was torn apart and replaced by Marvin Blanco 
(GE Turbine Tech.).  In addition, on or about this same date IGBT's were 
replaced within the same turbine.  Nowhere in the Monthly report are these 
issues mentioned, please explain?

* WTG#9 at Mill Run experienced downtime between 4-17-02 at 10:00 A.M. and 
4-24-02 at 4:00 P.M. this equates to 7 days - 6 hrs. or 7.25 days.  Assuming 
WTG#7 operated fault free the entire month (its availability at 100%) except 
for the above mentioned period of 7.25 days, the best possible availability 
that could be realized would be            (1-(7.25/30) x 100) = 75.8%.  
Please explain how the availability of this turbine can be 78.6% as listed in 
the Monthly Report?

* On 4-25-02 WTG#8 experienced several hours of repair time due to worn HV 
cable which had been rubbing against the ladder rungs at the yaw deck level.  
Apparently, the bundle of cables sways or moves during normal operation and 
over an extended period it caused significant wear to the protective 
coating/insulation.  Why was this not mentioned?  Are other turbines 
experiencing this problem?  Is there a retrofit being considered?

* On 4-28-02 a storm event with heavy winds rolled through the area.  
Turbines #2, #3, and #8 at Mill Run all experienced faults requiring 
component replacements.  The Summary on individual turbine activity in the 
monthly report does not reflect this, neither does the Consumption Log also 
contained within the Monthly Report, please explain?  In fact, WTG#8 required 
a new rack of IGBT's as a result of this storm event and no mention is made 
in the report to an IGBT replacement for this turbine.  Furthermore, on 
4-30-02 a new rack of IGBT's was installed in WTG#8 and they were blown upon 
start up.  IGBT's are major components, As a minimum I would expect the 
monthly reports to include major component failures/replacements.

* I need clarification on what exactly Section 7. EXHIBITS is attempting to 
demonstrate.  Surely, this is not an attempt to list all faults that a 
turbine experienced for the current month.  How are you selecting the faults 
you choose to include on the list?  For example, WTG#4 lists one (1) fault 
for the month and clearly that was not the case.  As one example, check the 
operational activity for WTG#4 on 4-22-02 where it experienced multiple 
faults among them "Gearbox Oil Pressure Too Low."

We have to have a better account of the operational history of these wind 
farms through GE Wind Monthly Reports.  I understand that the company as a 
whole has been consumed with many other tasks relating to the recent 
acquisition and that your attention has been elsewhere.  Nevertheless, we 
need to work together in order to improve the accuracy and attention to 
important details that is lacking within these reports.

I look forward to working with you and Joe to make these projects better and 
more accountable.

Best Regards,

Gary
