NEDC - Sutton

Located on the rooftop of the New England Distribution Center, this site allowed National Grid to avoid using excessive land for renewable development and explores the pros and cons of rooftop mounted solar generation. National Grid received regulatory approval for the project in October of 2009 and construction of this site was completed at the end of May 2010.

NEDC - Sutton

Environmental Benefits:

Construction of this project is estimated to save 2,800 pounds of sulfur dioxide, 1,300 pounds of nitrous oxides, and 1.3 million pounds of carbon dioxide per year. This is equivalent to the emissions produced in generating electricity for 200 average homes.

On this per year basis, the 1.3 million lbs of carbon taken out of the atmosphere is the equivalent of removing more than 124 passenger cars from the road; eliminating the CO2 emissions from burning 3.4 railcars of coal; or reducing the CO2 emissions from burning approximately 1,500 barrels of oil.
