Wind Development: An Evolving Art
In significant ways, the experience of
engineering support for wind
development in the U.S. is kind of a
frontier experience:
• Few widely applicable standards
• Many jurisdictions, and a highly
B lk i d regulatory
Balkanized
l t
scene
• Few commonly held expectations
about what we all, in our different
roles, can implicitly expect of each
other. How do we work together?

The owner’s engineer role on a wind
pproject
j sometimes offers flexibilityy
between two other parties that have
inflexible requirements from external
parties.
parties
• The development team is often
confined by permit milestones and
PPA
A contracts.
• The construction team is often

EPC contract
confined byy rigorous
requirements.
• The owner’s engineer often
functions as a washer or cushion
