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
State of New JerseyNew 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
