Greater Boston reliability project gets nod

Transmission towers at night We received some important backing recently about a series of projects we’ve proposed to improve grid reliability in the Greater Boston area.

ISO-NE (Independent System Operator – New England) announced on February 12, 2015 that a National Grid and Eversource Energy proposal is their preferred option to improve reliability in the Greater Boston power grid. ISO-NE recommended our proposal, the Greater Boston and New Hampshire Solution, over the alternate ‘Sealink’ proposal from Florida-based NextEra Energy.

The Greater Boston and New Hampshire Solution is estimated to cost at least $250 million less than the alternative proposal and will be easier and more cost-effective to repair, maintain, and expand over time.

“This is a win-win situation for Massachusetts residents and businesses since our solution will help to ensure the future reliability of the region’s electrical grid, while maximizing the project’s economic benefits,” said Rudy Wynter, President of National Grid’s Transmission Business. “We’re proud that ISO New England has designated ours as its preferred solution, and we look forward to working with local communities to make this proposal a reality.”

The Greater Boston and New Hampshire Solution will include three notable components:

  1. The Merrimack Valley Reliability Project: A new overhead 345-kV line in existing rights-of-way in Londonderry, Windham, Hudson, and Pelham, NH, and Dracut, Andover, and Tewksbury, MA (in service 2017)
  2. Woburn to Wakefield Line: A new underground 345-kV line through Woburn, Winchester, Stoneham, and Wakefield, MA (in service 2018)
  3. Everett to Woburn Line: A new underground 115-kV line through Everett, Boston (Charlestown), Somerville, Medford, Winchester, and Woburn, MA (in service 2018)

Each of the projects in the Solution will now move forward in siting and permitting approval processes. In anticipation of the decision, National Grid embarked on a public outreach campaign to engage thought leaders, decision-makers and communities around the Solution’s various project proposals in Greater Boston and Southern New Hampshire. This work will continue as the permitting process is underway.
