The state's Site Evaluation Committee is set to take up the question of whether a utility's application to string power lines from Canada to southern New Hampshire is complete.
The panel meets beginning at 9 a.m. Monday in Concord to consider the application by Eversource to build the Northern Pass transmission project.
Hartford, Connecticut-based Eversource wants to run a 192-mile transmission line from Pittsburg to Deerfield, carrying 1,090 megawatts of Canadian hydro-power to expensive markets in southern New England. Backers say it will create jobs and lower energy costs.
Opponents worry it will hurt property values, tourism and the environment.
The project is the subject of court challenges and the Society for the Protection of New Hampshire Forests has asked the SEC to declare the application incomplete.
