Gas Turbine Failures

David, I said I would send more descriptive data on our gas turbine failures.

The numbers may not be completely consistent with what I provided earlier because we have changed rules for counting valid demands and failures. They should be similar.

Failure to Start Year Demands Failures 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 16 63 54 80 73 47 33 48 35 33 44 8
