The SWCC Commissioners
 SWCC Commissioners review technical
reports from Brent, the Technical
Director
 Mike Klemen, Nolan Clark, Malcolm
Lodge
 Each has their strengths and spot
different anomalies that need
clarification
 The experience of the 3 commissioners
is complimentary to each other
What Commissioners do
 Review initial Certification Applications
 Check basic specifications to make
sure things like swept area calculations
are correct, that the documentation is
consistent, and ask for clarification
on this that don't make sense
What Commissioners do
 Review and approve/deny variations
from the standards
 Sometimes variations are allowed
 Sometimes testing must be restarted if
major changes are made
What Commissioners do
 When the final report is submitted, we
review hundreds of pages documenting
the procedures, data, and analyzed
results
Key points for Mike
 My strength is in reviewing data. I have
taken years of data from my turbines
and done lots of data analysis.
 I review data with a fine tooth comb. I
pay particular attention to design specs,
and verifying that the performance
falls within those specs.
 I pay lots of attention to the
safety and function test, verifying that
the turbine is protecting itself and is
under control
Example, RPM data are critical
