The stunning action – a formal decision was not required until February 23 – throws the clean energy procurement of Massachusetts into disarray.

By picking the Northern Pass project to import electricity from Canada just last week, the Baker administration gambled that officials in New Hampshire would support building 192 miles of transmission lines across their state.

That bet turned out to be badly misplaced.

The New Hampshire Site Evaluation Committee has voted unanimously to deny a permit to Eversource's controversial Northern Pass project.

On Thursday, the panel was in its third day of deliberations on whether to let the 192-mile transmission line proposal move forward.

CONCORD — The Mass. Office of Energy and Environmental Affairs will “monitor and evaluate” the Site Evaluation Committee’s “shocking” decision Thursday to deny Northern Pass’s application to build a controversial 192-mile transmission line from Pittsburg to Deerfield.

CONCORD — Northern Pass officials vowed to fight for their $1.6 billion project after a state committee unanimously voted Thursday to deny the project’s application.

Governor Charlie Baker is making a big bet on Northern Pass.

Massachusetts opted last week for one large power line to cover a big chunk of its energy needs for the next 20-plus years.
