A jolt for Cape Wind?

According to Patrick’s office, National Grid will soon file paperwork – a memorandum of understanding between the parties – with state utility regulators that spells out plans for an agreement.

A separate agency, the state’s Department of Energy Resources, will also sign the memorandum and if it’s approved, the talks can begin in earnest. State officials back the project, calling it a major boost for emissions-free power.

But Cape Wind's developers, who have been fighting for years to build the project, are hardly in the clear.

The federal Interior Department gave Cape Wind, which would be located in federal waters, a favorable environmental review early this year.

But a final federal sign-off has been delayed, most recently by questions about whether the waters should be included in the National Register of Historic Places. Two Native American tribes are seeking such a designation, which would create new hurdles for the project.
