Site
evaluation combines meteorological evaluation, environmental suitability, and
a lot of site engineering to determine requirements for ground support, power
transmission, access, etc., given the slopes and other characteristics of the
land. Site assessment starts by looking at a site and using local knowledge
about winds, permissions, access, transmission, etc.
This initial investigation is followed up by a preliminary meteorological study typically with SODAR and at least a 20 meter meteorological tower. During this period, wind data is referenced to other local stations. The longer the overlapping records, the more accurate the eventual estimates.
If preliminary data look promising, larger towers, typically 50 meters, are
erected and additional SODAR work is generally warranted. Final studies almost
always require the review of a consulting meteorologist experienced in wind
energy modeling in complex terrain. Davis
Wind is currently using SODAR and standard 20 – 50 Meter meteorological
towers to evaluate the potential of prospective sites.
Wind assessment is critical, but not sufficient to determine whether a site is suitable for wind power. Site permitting, access, and environmental acceptability is necessary to be considered. Dr. Ely heads the overall siting evaluation effort. Ms Sackheim focuses on community relations, permitting and environmental assessment.
