The Northern Pass project will go back before the state Site Evaluation Committee next month.
The panel denied the huge power line proposal in February, and developer Eversource had asked it to reconsider.
Now that its written denial of the project is out, the committee has set a hearing on the issue for May 24 in Concord, with an extra day scheduled for June 4 if necessary.
Eversource wants a second chance at the last permit it needs for Northern Pass to be built.
It would carry Canadian hydropower over 200 miles from Quebec, through the White Mountains to central New Hampshire, where it would hook into the New England power grid.
If New Hampshire regulators don't want to re-hear the case, the utility will likely appeal to the state Supreme Court.
