A question arose regarding the many operations of our breaker in the pad mounted transformer that took place December through March. Gary's thought is that when we recalculate the availability, we need to count these times as down time and not Line Out Hours as they have currently been counted. I suggested that according to Exhibit GG in the TSIA, LOH is defined in short as any time the grid does not meet "(i) the specifications required by the WTG as set forth in the Technical Specifications", and Gary agrees with this. The problem is that an engineering change on the breaker settings was implemented some time in March to reduce the number of breaker operations on site. We are still seeing many grid faults in the turbine but not in the PMT breaker. The question that Gary brought up is were the original settings of the breaker set to the WTG Technical Specifications and operating due to the on going grid conditions OR were the settings improper to start with causing the breaker to operate while the grid was within Technical Specifications.
