Analysis of the Wind Resource off New Jersey for Offshore Wind Energy Development Hugh Roarty, Joe Riscica, Laura Palamara, Louis Bowers, Greg Seroka, Josh Kohut, Scott Glenn and Rich Dunk

New Jersey Renewable Goals 23% of its energy from renewable sources by 2021 The nation’s first offshore wind renewable energy standard which requires at least 1,100 megawatts (MW) by 2021 Currently at 0.0 MW

An Advanced Atmosphere/Ocean Assessment Program: State of New Jersey New Jersey Board of Public Utilities (NJBPU) An Advanced Atmosphere/Ocean Assessment Program: Reducing the Risks Associated with Offshore Wind Energy Development As Defined by The NJ Energy Master Plan and The NJ Offshore Wind Energy Economic Development Act Principal Investigators: Dr. Scott Glenn and Dr. Rich Dunk, CCM Team Members: Dr. Josh Kohut, Dr. Hugh Roarty, Louis Bowers, Greg Seroka, John Kerfoot, Laura Palamara, Mike Crowley, Ethan Handel, Colin Evans New Ocean Data Hi-Res Weather Model Spatial Validation Data Wind Power Statistics -Demonstrate variability of the offshore wind resource for designated study area by using high resolution nested atmospheric WRF model -Validate modeling efforts with existing data as well as with developer’s coastal/offshore data (scanning LIDAR, axis LIDAR, three 60m coastal met towers) -NJ sea breeze has large impact on wind resource during peak energy demand season -Sea surface temperature is a critical input variable to the atmospheric model for producing accurate wind resource assessments; RUCOOL has developed a unique technique for declouding satellite imagery to ensure that coastal upwelling and storm mixing processes can be resolved -CODAR is a unique monitoring system for detecting surface currents and the associated spatial wind variability within the study area; wave data and spatial variability of the waves from CODAR can also be used to determine surface roughness features which is an input to the atmospheric model -This work can be used as a basis for a representative forecasting/predicting program
