The 320-kV DC underground cable project will provide a conduit for renewable energy from eastern Canada, and northern and eastern Maine; and improve reliability. The approximately 240-mile project will run from the Orrington Substation in northern ME to Tewksbury, MA. The project is being sponsored by Bangor Hydro (a Emera Inc. company) and National Grid USA. The project is being supported by First Wind Holdings headquarted in Boston, MA by plans to develop wind farms in northern and eastern Maine. The project will also enable increased imports of renewable power from New Brunswick throught the recently completed Northeast Reliability Interconnection — the 2nd 144-mile 345-kV circuit developed between Point Lepreau nuclear plant in NB to Orrington substation.
