• Conceived as underground DC cable (two conductors) extending approximately 220 miles
• Several alternative routing scenarios are being considered, including land-based (both overhead and underground) and submarine
• Capacity range from 660 to 2200 MW at +/- 320kV DC.
• Higher transfers may dictate an extension to New Brunswick or Quebec
• AC/DC converter stations on each end
• DC technology is more efficient for long-distance transmission and underground construction

Routing
The preferred project design at this point calls for an overland route from Orrington, Maine to Tewksbury, Massachusetts. Current planning also calls for a route utilizing existing utility or transportation corridors which parallel the Maine, New Hampshire, and Massachusetts coastline. An underground design is being considered and would result in a small project footprint and minimal new environmental disturbance. Before the final scope is established, a submarine cable option and combination alternatives will also be evaluated.

Technical Evaluation Process
A technical feasibility study was conducted in late 2007 which showed this to be an achievable project. In February, presentations were received from key vendors for converter station technology. Further evaluation of cable technology is getting underway. Civil contractors are being engaged to understand installation logistics.

Finalization of scope definition will lead to the initiation of a system study, and a more detailed routing alternative analysis will be conducted. Additional evaluations will include: termination points, co-location issues, material availability, refined cost estimates, procurement processes, and timing.

Summary
The Northeast Energy Link project will establish a critical transmission path enabling renewable generation sources to reach New England markets. The approval and completion of this project brings significant benefits to the electric system and consumers of New England, including the reduction in electricity cost to customers, and positive environmental results from the import of clean, renewable energy sources. Both National Grid and Bangor Hydro are very experienced in large transmission development. This is an advanced and achievable project with sound economic justification, the use of proven technology, the right geographical location, and solid energy input and output assumptions.
