More than two years after the Patrick administration committed to a $35 million New Bedford marine terminal project to serve as a staging ­area for Cape Wind, state officials are now talking up a complex, $100 million project while the developers of the offshore wind farm have held talks with Rhode Island about using that state as a project assembly area.

In New Bedford in October 2010, Governor Deval Patrick announced that a multipurpose terminal would be built there to support offshore wind efforts, with construction costs estimated at $35 million, and said the new pier would capture 600 to 1,000 Cape Wind jobs.
