Mark did a great job of demonstrating the usefulness of the Mon.db file to Gary for the purpose of calculating availability, and also the method used by GE wind to determine availability. By the end of the second day Gary expressed he had a new found confidence in the accuracy of the Mon.db file data and also in general agreed with the method GE Wind used to calculate availability. Gary did express a few concerns which are listed below. Gary was concerned that we may continue to overlook the fact the turbine may have been put into virtual mode. Mark reassured Gary that new measures were being taken to prevent this situation from being overlooked in the future and during the recalculation of the availability. Gary also expressed that he could see no problem with the 4 hours of maintenance time that was being added each month as long as, in the monthly report the actual availability is list in a sperate column as the adjusted availability. Gary felt that in the recalculation of the availability it may be warranted to count the many breaker operations that occurred in the first few months of the project as downtime rather then Line Out Hours as they may have been counted. This was due to the fact that we made a adjustment to the breaker that later prevented it from tripping as often. This suggested to Gary that the breaker trips were in fact due to improper settings. Another suggestion by Gary was that after a fault, the turbine could take as long as 1 to 2 minutes to began producing as the turbine performed its run up sequence. Gary suggested that during the winter months when the turbines experienced hundreds of Low Gearbox Oil Pressure faults, that this 1 to 2 minute run up sequence would equate to several hundred minutes were the turbine reported available, but was not truly available to produce. He concluded that in the recalculation we may want to count this time as downtime. When asked what method could be agreed upon during the recalculation, Gary stated that after reviewing the method we used he could see no problem with it as long as we did not overlook things like the virtual mode. Gary also stated that as long as the final availability was within 1% of his calculations he would have no complaints. If the final availability numbers were greater then 1% of his calculations then he would need a break down of what was counted and what was not counted for review.
