If we are only talking about a .6% drop in avg. availability, we had better
be ready to defend our numbers. Not just defend but convince Zilkha why we are right with our calcs. Mark F. unless I am mistaken, Gary V. is expecting a bigger drop?? --------------------- Forwarded by Kurt Anderson/EWC/Enron on 07/10/2002 04:03 PM --------------------------- Mark V Walker 07/10/2002 02:04 PM To: Kurt Anderson/EWC/Enron@ENRON cc: Hollis Kimbrough/EWC/Enron@ENRON Subject: Mill Run report through May with Virtual Mode corrections. Summary: The Jan - May 2002 availabilities are revised to exclude virtual mode / pause events. The results showed that every turbine had between one and two hours each month where the WTG was transitioning between states as per design. Therefore, the resulting total hours of pausing and virtual mode for each turbine was decreased by one and a half hours. In addition the pausing due to noise curtailment at turbine 7 between the hours of 7 PM and 5 AM local time was excluded. No other changes were made to the SCADA data. The net result is that the Jan availability dropped by 1.5%, Feb dropped by 0.4%, Mar dropped by 0.3%, Apr dropped by 0.1%. Dec 2001 data was not corrected due becasue the data recovery of the minana files in that month was very poor. The Somerset report is well underway and will be in a similar form.
