Updated Eastern Interconnect Wind Power Output and Forecasts for ERGIS: July 2012

NREL, Kara Clark (NREL Technical Monitor)

Research output: NRELSubcontract Report


AWS Truepower, LLC (AWST) was retained by the National Renewable Energy Laboratory (NREL) to update wind resource, plant output, and wind power forecasts originally produced by the Eastern Wind Integration and Transmission Study (EWITS). The new data set was to incorporate AWST's updated 200-m wind speed map, additional tall towers that were not included in the original study, and new turbinepower curves. Additionally, a primary objective of this new study was to employ new data synthesis techniques developed for the PJM Renewable Integration Study (PRIS) to eliminate diurnal discontinuities resulting from the assimilation of observations into mesoscale model runs. The updated data set covers the same geographic area, 10-minute time resolution, and 2004?2006 study period for thesame onshore and offshore (Great Lakes and Atlantic coast) sites as the original EWITS data set.
