Appalaches-Maine Interconnection

Hydro-Québec began construction on the Appalaches–Maine interconnection line project.  

The project, which involves a new 320-kV direct-current transmission line about 100 km long, has therefore officially entered the construction phase. The work at Appalaches substation is also under way.  

In coming weeks, Hydro-Québec will begin creating access roads and clearing land for the line’s right-of-way on properties for which agreements have been concluded.
