Please let me know if there are any questions. Gary was unable to find any information in the TSIA that outlined the procedure that we currently use to record maintenance time of 4 hours per month instead of recording the time as it is used. Gary had a conversation with Mike Kelly whom assured him that this has not been done in the past and seems to be an incorrect way to report the maintenance time. Gary also stated that this would lead to error in availability in months were there were 28 days in the month compared to a month with 31 days Mark Howller & Mike Kelly have also conveyed to Gary that using 10 min data to calculate estimated power production and availability was an industry standard. In an attempt to complete the sale of the site, Zilkha has been asked to provide 10 minute data to their potential customers. Grays questions is why are we not using the 10 minute data files to calculate our availability. Gary also wanted to know how the Mon.db file could be more accurate then the Minana.db file, if the Mon.db file is taking samples from other files, and the other files have missing data like the Minana.db does. He also wanted to know how the Mon.db file could be verified if there happened to be a mistake as there appears to be on turbine 9 for the month of April. Where is the raw data proving the numbers in the Mon.db file. We also discussed the faults on turbine 4 for the month of April. Gary stated that the faults he outlined in his letter came from the errordev.db file. He was unaware of the state of the turbine at the time of the faults or if they contributed to down time or not. I am researching this and will inform you as soon as I know. Gary also per warned me of an Email that is planning to go out to Mike Miller. The letter states that over the past 6 months our turbines have performed poorly, and we have attempted to mislead them by over stating out availability. We have also misstated the amount of parts used on site and we have not explained problems to Zilkha, that we are experiencing with our turbines. He also states that we have not provided maintenance's to our turbines in the last 7 months.
