Kurt & John, I am forwarding this Email from Gary. At this time I have not completed investigating this problem, when I do I'll let you know so far I have been unable to find a reason for this. ---------------------- Forwarded by Joe Thorpe/EWC/Enron on 06/10/2002 02:32 PM --------------------------- GVerkleeren@zilkha.com on 06/07/2002 01:19:32 PM To: joseph.thorpe@ps.ge.com cc: Subject: SCADA & Misc. Joe, Upon my review of the mon files for Mill Run, I have discovered some discrepancies surrounding the recent grid outage on 6-5-02 that require corrective action. The Mill Run site experienced grid downtime on 6-5-02 between 2115 and 2330 hours for a total of 2 hrs and 15 minutes. The associated grid downtime that was logged by the mon files within Visupro recorded the following: WTG#1 - 2hrs 20 minutes WTG#2 - 2hrs 22 minutes WTG#3 - 2hrs 24 minutes WTG#4 - 2hrs 26 minutes WTG#5 - 2hrs 18 minutes WTG#6 - 4hrs 46 minutes WTG#7 - 2hrs 12 minutes WTG#8 - 5hrs 02 minutes WTG#9 - 2hrs 16 minutes WTG#10 - 2hrs 22 minutes The majority of the turbines are within reason except for turbines #6 and #8 which have recorded more than double the actual grid downtime. In addition, WTG#4 reports no data in the mon file for 6-2-02, Can you explain this occurrence? This is not the first time data has been observed to be missing from the mon file of an individual turbine. I also noted that WTG#5 experienced more than 10 hours on repair on 6-6-02, Was there a failed component that was replaced on this date? As previously discussed, I want Visupro to be an effective tool for both you and me. We need to work together to work out all of the bugs and reporting malfunctions so that we can have a high level of confidence that it is performing calculations and reporting accurately. Please forward my concerns to the appropriate people within GE so as to respond to these couple of items in a timely manner. Understanding the mon file discrepancy in particular will be useful for the upcoming meeting with GE personnel to work through the availability calculations. Furthermore, please provide me with the field reports for the shaft inspections recently performed at Mill Run. Am I correct in saying that 3 shafts were tested at Mill Run and none at Somerset? I look forward to your responses Gary Gary Verkleeren Zilkha Renewable Energy 68 Braddock Drive Ohiopyle, PA 15470 Office: 724 434-1542 Mobile: 724 554-0924 Fax: 724 434-1543
