costs. More importantly, this generalized set of turbines (herein after referred to as
the 10-turbine analysis group) provides a very useful datum for comparing value
analysis results with actual or derived mass and cost data.

2.1 Value analysis for wind

Based on extensive value analysis experience for a wide range of real project
economics, up-scaling today's most popular turbine architectures and component
technologies beyond 4 5 MW results in unfavourable customer economics. The

very best value analysis procedures today are computerized in a format that allow
individual component owners to keep their models updated. These procedures
ensure that the modules maintain their functionality relative to each other and in
the overall roll-up to the WPP and electrical grid views.

2.1.1 The cost for value analysis
A rigorous value analysis program is an investment that an OEM must make to ensure
that every dollar spent on new WT technologies or products will result in satisfi ed
