Wind Resource Reporting Assigned to IEC

Sacramento, Calif., April 1, 2008 – IEC has been assigned to develop quarterly wind resource reports based on data downloaded from meteorological towers (confidential location). Equipment on the two towers measures and records wind speeds, wind direction, and temperature. The towers are equipped with Satellite iPack telecom systems that are used for transmitting the stored data. The scope includes: reviewing and cleaning stored data; reporting numbers of missing data elements from each sensor; determining monthly average hourly wind speeds; determining average quarterly wind direction; and calculating wind shear coefficients. IEC is then responsible for extrapolating wind speeds to 80m using wind shear coefficients and using estimated 80m wind speed to drive power curves for three commercially available utility class wind turbine generators. From this information, IEC will then estimate peak energy losses and calculate total monthly and quarterly MWh productions for the three WTGs. Quarterly reports will be submitted to the client for use in future decision-making processes.
