Cape Wind, Massachusetts (2001-2017)
A 468-megawatt wind farm proposed for Nantucket Sound spent more than a decade in permitting. It cleared federal review in 2010, but local opposition, litigation and the collapse of its power contracts kept it from being built.
The developer won permits but could not secure buyers for the electricity.
The project was abandoned in 2017 and its permits surrendered. No turbine was installed.
Baldon now has the same split: a planning approval in hand and no confirmed route to sell most of its output.
