AWEA Wind Resource &
Project Energy Assessment Workshop

September 24 - 25, 2008
Portland, OR

Program Agenda Print Agenda

Program Chairperson:
Clint Johnson
, Vice President - Energy Assessment & Development Services,
Garrad Hassan America, Inc.

(A couple of special meetings are scheduled in conjunction with this workshop. Click here to see the schedule.)

Tuesday, September 23

1:00 pm – 6:00 pm
Optional Pre-Conference Seminar
Introduction to Wind Energy

(additional fee required – not included
in conference registration!
)

NOTE: The workshop includes a half-day pre-conference seminar which will provide an introduction to wind energy with a concentration on resource assessment—an ideal offering for those new to the wind industry or seeking a basic background in resource assessment issues. Since the topics covered during the actual workshop will be presented at a technical level, attending the pre-conference seminar is recommend for those with little or no prior knowledge of resource assessment.
